The BEST Way to Use Cardio to Lose Fat (Based on Science)

Elevated fat-burning efficiency -

This accumulation of lipid and its metabolites in the muscle may interfere with the insulin-signalling cascade and cause insulin resistance. It is therefore important to understand the factors that regulate fat metabolism, and the ways to increase fat oxidation in patients and athletes.

Fats are stored mostly in subcutaneous adipose tissue, but we also have small stores in the muscle itself intramuscular triglycerides. At the onset of exercise, neuronal beta-adrenergic stimulation will increase lipolysis the breakdown of fats into fatty acids and glycerol in adipose tissue and muscle.

Catecholamines such as adrenaline and noradrenaline may also rise and contribute to the stimulation of lipolysis. As soon as exercise begins, fatty acids are mobilised. Adipose tissue fatty acids have to be transported from the fat cell to the muscle, be transported across the muscle membrane and then be transported across the mitochondrial membrane for oxidation.

The triglycerides stored in muscle undergo similar lipolysis and these fatty acids can be transported into the mitochondria as well.

During exercise, a mixture of fatty acids derived from adipocytes and intramuscular stores is used. There is evidence that shows that trained individuals store more intramuscular fat and use this more as a source of energy during exercise 1.

Fat oxidation is regulated at various steps of this process. Lipolysis is affected by many factors but is mostly regulated by hormones stimulated by catecholamines and inhibited by insulin. The transport of fatty acids is also dependent on blood supply to the adipose and muscle tissues, as well as the uptake of fatty acids into the muscle and into the mitochondria.

By inhibiting mobilisation of fatty acids or the transport of these fatty acids, we can reduce fat metabolism. However, are there also ways in which we can stimulate these steps and promote fat metabolism?

Exercise intensity — One of the most important factors that determines the rate of fat oxidation during exercise is the intensity. Although several studies have described the relationship between exercise intensity and fat oxidation, only recently was this relationship studied over a wide range of intensities 2.

In absolute terms, carbohydrate oxidation increases proportionally with exercise intensity, whereas the rate of fat oxidation initially increases, but decreases again at higher exercise intensities see figure 1.

So, although it is often claimed that you have to exercise at low intensities to oxidise fat, this is not necessarily true. However, the inter-individual variation is very large.

However, very little research has been done. Recently we used this intensity in a training study with obese individuals. Compared with interval training, their fat oxidation and insulin sensitivity improved more after four weeks steady-state exercise three times per week at an intensity that equalled their individual Fatmax 4.

Dietary effects — The other important factor is diet. A diet high in carbohydrate will suppress fat oxidation, and a diet low in carbohydrate will result in high fat oxidation rates. This effect of insulin on fat oxidation may last as long as six to eight hours after a meal, and this means that the highest fat oxidation rates can be achieved after an overnight fast.

Endurance athletes have often used exercise without breakfast as a way to increase the fat-oxidative capacity of the muscle. Recently, a study was performed at the University of Leuven in Belgium, in which scientists investigated the effect of a six-week endurance training programme carried out for three days per week, each session lasting one to two hours 6.

The participants trained in either the fasted or carbohydrate-fed state. When training was conducted in the fasted state, the researchers observed a decrease in muscle glycogen use, while the activity of various proteins involved in fat metabolism was increased.

However, fat oxidation during exercise was the same in the two groups. It is possible, though, that there are small but significant changes in fat metabolism after fasted training; but, in this study, changes in fat oxidation might have been masked by the fact that these subjects received carbohydrate during their experimental trials.

It must also be noted that training after an overnight fast may reduce your exercise capacity and may therefore only be suitable for low- to moderate- intensity exercise sessions. The efficacy of such training for weight reduction is also not known. Duration of exercise — It has long been established that oxidation becomes increasingly important as exercise progresses.

During ultra-endurance exercise, fat oxidation can reach peaks of 1 gram per minute, although as noted in Dietary effects fat oxidation may be reduced if carbohydrate is ingested before or during exercise.

In terms of weight loss, the duration of exercise may be one of the key factors as it is also the most effective way to increase energy expenditure. Mode of exercise — The exercise modality also has an effect on fat oxidation.

Fat oxidation has been shown to be higher for a given oxygen uptake during walking and running, compared with cycling 7. The reason for this is not known, but it has been suggested that it is related to the greater power output per muscle fibre in cycling compared to that in running.

Gender differences — Although some studies in the literature have found no gender differences in metabolism, the majority of studies now indicate higher rates of fat oxidation in women. In a study that compared men and women over a wide range of exercise intensities, it was shown that the women had higher rates of fat oxidation over the entire range of intensities, and that their fat oxidation peaked at a slightly higher intensity 8.

The differences, however, are small and may not be of any physiological significance. There are many nutrition supplements on the market that claim to increase fat oxidation.

These supplements include caffeine, carnitine, hydroxycitric acid HCA , chromium, conjugated linoleic acid CLA , guarana, citrus aurantium, Asian ginseng, cayenne pepper, coleus forskholii, glucomannan, green tea, psyllium and pyruvate.

With few exceptions, there is little evidence that these supplements, which are marketed as fat burners, actually increase fat oxidation during exercise see table 1. One of the few exceptions however may be green tea extracts.

The mechanisms of this are not well understood but it is likely that the active ingredient in green tea, called epigallocatechin gallate EGCG — a powerful polyphenol with antioxidant properties inhibits the enzyme catechol O-methyltransferase COMT , which is responsible for the breakdown of noradrenaline.

This in turn may result in higher concentrations of noradrenaline and stimulation of lipolysis, making more fatty acids available for oxidation. Environment — Environmental conditions can also influence the type of fuel used. It is known that exercise in a hot environment will increase glycogen use and reduce fat oxidation, and something similar can be observed at high altitude.

Similarly, when it is extremely cold, and especially when shivering, carbohydrate metabolism appears to be stimulated at the expense of fat metabolism.

At present, the only proven way to increase fat oxidation during exercise is to perform regular physical activity. Exercise training will up-regulate the enzymes of the fat oxidation pathways, increase mitochondrial mass, increase blood flow, etc.

Research has shown that as little as four weeks of regular exercise three times per week for minutes can increase fat oxidation rates and cause favourable enzymatic changes However, too little information is available to draw any conclusions about the optimal training programme to achieve these effects.

In one study we investigated maximal rates of fat oxidation in subjects with varying fitness levels. In this study, we had obese and sedentary individuals, as well as professional cyclists 9.

VO2max ranged from Interestingly, although there was a correlation between maximal fat oxidation and maximal oxygen uptake, at an individual level, fitness cannot be used to predict fat oxidation. What this means is that there are some obese individuals that have similar fat oxidation rates to professional cyclists see figure 2!

The large inter-individual variation is related to factors such as diet and gender, but remains in large part unexplained. Fat burning is often associated with weight loss, decreases in body fat and increases in lean body mass.

However, it must be noted that such changes in body weight and body composition can only be achieved with a negative energy balance: you have to eat fewer calories than you expend, independent of the fuels you use!

The optimal exercise type, intensity, and duration for weight loss are still unclear. Current recommendations are mostly focused on increasing energy expenditure and increasing exercise volumes.

Finding the optimal intensity for fat oxidation might aid in losing weight fat loss and in weight maintenance, but evidence for this is currently lacking. It is also important to realise that the amount of fat oxidised during exercise is only small. Fat oxidation rates are on average 0.

So in order to oxidise 1kg of fat mass, more than 33 hours of exercise is required! The duration of exercise, however, plays a crucial role, with an increasing importance of fat oxidation with longer exercise. Of course, this also has the potential to increase daily energy expenditure.

If exercise is the only intervention used, the main goal is usually to increase energy expenditure and reduce body fat. When combined with a diet programme, however, it is mainly used to counteract the decrease in fat oxidation often seen after weight loss Higher fat oxidation rates during exercise are generally reflective of good training status, whereas low fat oxidation rates might be related to obesity and insulin resistance.

The vast majority of nutrition supplements do not have the desired effects. Currently, the only highly effective way to increase fat oxidation is through exercise training, although it is still unclear what the best training regimen is to get the largest improvements.

Finally, it is important to note that there is a very large inter-individual variation in fat oxidation that is only partly explained by the factors mentioned above. This means that although the factors mentioned above can influence fat oxidation, they cannot predict fat oxidation rates in an individual.

High Intensity Training. Environmental Training. Recovery Strategies. For extremely high-intensity activity, your body uses the phosphagen system.

As intensity decreases from extremely high, you shift to the glycolytic system and, eventually, to the oxidative system for moderate- to low-intensity activity. The phosphagen system is responsible for producing short-acting, rapidly available energy. When you start physical activity, you use existing stores of ATP quickly.

Since you can only store a relatively small amount of ATP, the phosphagen system uses creatine phosphate CP, also called phosphocreatine to make more ATP.

CP is a molecule your body uses primarily to create ATP very quickly, rather than carbs or fat. You can build your CP stores in two ways. First, you can get it through your diet by eating red meat and fish.

Your body also makes CP from amino acids in your liver, kidneys, and pancreas. For activity longer than 10 seconds, your body activates the glycolytic system to make more ATP. The glycolytic system uses carbohydrates—blood glucose and muscle glycogen—to produce ATP.

Fast glycolysis is somewhat inefficient, producing only a small amount of ATP from glucose. Slow glycolysis requires oxygen and takes longer to make ATP because the process involves many more steps than fast glycolysis. While it lacks speed, it efficiently produces more ATP per molecule of glucose—or muscle glycogen—than fast glycolysis does.

So, you need both fast and slow glycolysis to produce ATP: the former to meet your immediate need for energy, and the latter to sustain energy. It enables you to oxidize burn using oxygen all 3 macronutrients —carbs, fat, and protein.

However, your system uses protein for energy only in times of starvation and during exercise sessions longer than 90 minutes. Even then, the amount of protein used to produce ATP is small compared to the amounts of carbs and fat used.

Then, when you exercise longer than 3 minutes, the ratio shifts back to using fat to produce ATP, especially as you reach 30 minutes or longer. Fat oxidation is the slowest but most efficient method of producing ATP.

It produces the most ATP per molecule of fat burned. High-intensity exercise and short-duration, moderate-intensity exercise almost exclusively use CP and carbs to produce more ATP. However, fat oxidation continues at a relatively high rate after a long or intense workout to help your body recover and replace ATP.

Appropriate rest between exercise sets, and recovery between workout days, allows you to build back your energy stores. For example, muscular-endurance training requires less rest between sets because you train your body in a relatively low energy state.

It allows your muscles to perform endurance tasks for longer over time. Strength , hypertrophy , and power training all require longer rest periods between sets to build back ATP and CP stores, so you can apply maximum force to your lifts.

How do your energy systems influence weight management? Managing your weight is largely a game of calories in versus calories out, with some other factors such as genetics and hormone levels. Cardiorespiratory cardio training burns more calories per hour of exercise than resistance training because it gives your body more time to activate your slow glycolysis and oxidative systems.

For cardio, as a general rule, you burn about calories for every mile traveled by foot—walking or running. However, where those calories come from—carbs or fat—depends entirely on the intensity and duration of the exercise.

Since 2 miles is a fairly short distance, you will probably finish the run in less time than it takes for your body to start the fat-oxidation process.

Resistance training for muscular strength and hypertrophy primarily uses the phosphagen system and fast glycolysis for energy. Your body can burn about calories per hour during intense weightlifting.

So how can we know at which point our body will switch from using fat to other fuels for energy? One approach researchers take is assessing how much fat is being used for energy during different exercise intensities. By measuring how much air a person expels during an exercise test which gets progressively harder, physiologists have been able to calculate the relative contributions of fat and carbohydrates to meet the exercise demand at different intensities.

The rate of fat being burned starts to decline at higher intensities as the body requires energy more rapidly. Another point to consider is how much fat we actually burn during exercise if we express it in grams per minute. The answer is: surprisingly little. Even in studies with athletes, at FATmax, participants only burned on average a mere 0.

This would equate to around 30 grams of fat per hour. In the average person, this appears to be even lower, ranging between 0. To put it in perspective, one pound of fat weighs around grams. So, though training in this fat burning zone will help with fat loss, this might also help explain why it takes some people longer to lose fat through exercise.

But there is evidence that following certain diets such as intermittent fasting or a ketogenic, high fat diet and longer exercise can increase the actual amount of fat we burn.

What You Need to Know About Burning Fat	Caffeine is a drug used all over the world, usually for its stimulant effects. It increases alertness, lowers the perceived exertion of exercise, and decreases reaction time. Caffeine is also known as a fat burner. It works by increasing the rate of fatty acid metabolism. It also decreases the rate of carbohydrate glucose metabolism during aerobic exercise. Green tea also has caffeine, though less than coffee. That makes it preferable to people who are sensitive to this ingredient. You can find green tea drinks in almost any convenience store. Protein is known for increasing metabolism. This fat burning nutrient also suppresses your appetite. It fills you up, so you feel fuller longer. A review in Nutrition and Health looked at 21 studies involving a weight loss supplement. It found that a thermogenic fat burner may provide limited benefits. However, a supplement was less effective than exercise alone or diet combined with exercise. Some research has looked at the effectiveness of individual ingredients. They also had a greater decrease in body mass index. Though, the magnitude of weight loss decreased significantly over time. This suggests that carnitine may provide better results in the short versus long-term. Another study involved subjects consuming caffeine pre workout. After two weeks, the group receiving caffeine had a greater decrease in body fat. Yet, there was no difference in energy expenditure at rest or during exercise. Instead, caffeine appeared to increase energy post workout. Studies involving green tea extract have also shown positive results. One involved overweight female participants. Those receiving green tea extract had greater weight loss. They also had more improved body fat percentages. Some research even connects green tea with greater belly fat loss, specifically. What about protein for fat loss? One review reports that higher protein intake helps athletes achieve weight loss without losing muscle mass. It also provides increased energy for making it through their training. Although some supplements have promising effects, there are concerns about their safety. For instance, consuming too much caffeine is known to raise blood pressure. Increased blood pressure puts people at risk of heart attack and death. In some cases, the use of a fat burner has led to other health issues. For instance, one case report connected this type of supplement with acute liver failure. Another linked a fat burner with the development of severe lactic acidosis. This is when the body produces more lactic acid than it can metabolize. One such ingredient is 2,4-Dinitrophenol or DNP. Research indicates that DNP has health risks for humans, to the point where they recommend it be banned for consumption. Yet, out of 94 supplements reviewed, 14 contained DNP. DNP was used in medical practice in the s but was found to have severe toxicity. So, it was withdrawn from use. Now it is used by bodybuilders and extreme dieters. It works by inhibiting energy production in the cells. This aids in fat loss. Unfortunately, there is no one-size-fits-all answer to this question. Longer-duration cardio will help contribute to your daily calorie deficit because you need to burn a lot of carbs and fat to support the workout.

How your body burns fat and carbs during exercise. Weight management How do your energy systems influence weight management? However, the reality is more complex. According to an older study from , the optimal heart rate for burning fat is actually between The American Council on Exercise ACE caution against relying too heavily on the fat burning heart rate. They suggest that a person should work with a fitness trainer to help determine their exercise capabilities. The ACE also have their own heart rate chart that shows heart rate zones based on age and the fitness level of the person. Like the authors of the study, the ACE also point out that a person will burn fat regardless of whether they are in the fat burning or cardio zone during exercise. Still, for some, keeping an eye on their heart rate during exercise can help them maintain their intensity or pick up their pace if the activity is not challenging enough. A person should always speak to a doctor before starting a new exercise program. A doctor or other healthcare provider can recommend healthy heart rate levels and other tips for people who are looking to lose weight. However, people will burn calories and fat regardless of their heart rate when exercising. A person who is interested in burning fat should discuss their goals with a doctor, who can recommend exercises and safe heart rates based on their needs and fitness levels.

Heart rate zones: How to find your max heart rate for fat burning	Other research, however, has found that increased fat intake does result in greater fat oxidation during exercise. Researchers from New Zealand compared the effects of a day high-carbohydrate diet, a day high-fat diet, and an Performance in the minute test was slightly better after the high-carb diet, but not to a statistically significant degree, while performance in the km test was slightly better, but again not to a statistically significant degree, following the high-fat diet. Fat oxidation was significantly greater during the km test following the high-fat diet. Like this study, other studies have also suggested that, while increased fat intake may increase endurance, it may also reduce performance in shorter higher-intensity races. The rationale for this approach is that a couple of weeks on a high-fat diet will stimulate increases in fat oxidation capacity during exercise, and that following this adaptation period with a couple of days of carbo-loading immediately preceding a race or other maximal endurance effort will maximize muscle glycogen stores, so the athlete has the best of both worlds. A recent study from University of Cape Town, South Africa, suggests that this strategy just might work. Researchers examined the effects of a high-fat diet versus a habitual diet prior to carbohydrate loading on fuel metabolism and cycling time-trial performance. Five trained cyclists participated in two day randomized cross-over trials during which they consumed either a 65 percent fat diet or their habitual 30 percent fat diet for 10 days, before switching to a 70 percent carbohydrate diet for three days. All subjects then performed a cycling test consisting of 2. The high-fat diet resulted in increased total fat oxidation and reduced total carbohydrate oxidation during exercise. Most noteworthy, the high-fat treatment was also associated with improved time trial times. On average, the cyclists completed the km time trial 4. The problem with this study is that the design of the exercise test was biased to take advantage of improved fat burning. The initial 2. But if this study had instead involved a time trial after a standard warm-up, it is unlikely that the high-fat diet would have been seen to result in better performance. Indeed, other studies have found that a high-fat diet followed by a carbo-loading phase impairs performance in high-intensity time trials. Perhaps the best-known advocate of this approach was Phil Maffetone, an endurance sports coach who made his name by developing a training philosophy that was characterized by an extreme emphasis on the importance of fat metabolism. Over time, Maffetone believed, the athlete would be able to swim, bike or run faster and faster at the same, low, fat-burning intensity. Conversely, diets high in whole grains are tied to a lower body mass index BMI and body weight, plus a smaller waist circumference Aim to replace refined carbs from pastries, processed foods, pastas, white breads, and breakfast cereals with whole grains like whole wheat, quinoa, buckwheat, barley, and oats. Cardio, also known as aerobic exercise, is one of the most common forms of exercise. Adding cardio to your routine may be one of the most effective ways to enhance fat burning and weight loss. For example, one review of 15 studies tied increased aerobic exercise to decreased belly fat in middle-age women Other studies have found that aerobic exercise may increase muscle mass and decrease belly fat, waist circumference, and body fat 32 , 33 , Most research recommends — minutes of moderate to vigorous exercise per week, or roughly 20—40 minutes of cardio each day Running, walking, cycling, and swimming are just a few examples of cardio workouts. Studies show that the more aerobic exercise people get, the more body fat they tend to lose. Cardio may also help reduce waist circumference and increase muscle mass. The caffeine in coffee stimulates your central nervous system, increases metabolism, and boosts the breakdown of fatty acids Caffeine has also been shown to enhance fat burning during aerobic exercise, particularly for those who are untrained or sedentary One large review of 12 studies associated increased coffee intake with a lower risk of obesity, especially for men. Another study including 2, people linked higher caffeine intake to a higher rate of success with weight loss maintenance 38 , To maximize the health benefits of coffee, avoid adding large amounts of cream and sugar. Instead, enjoy it black or with a small splash of milk. Coffee contains caffeine, which may boost metabolism and fat breakdown. Studies suggest that high caffeine intake may aid weight loss. High intensity interval training HIIT is a form of exercise that pairs quick bursts of activity with short recovery periods to keep your heart rate elevated. Studies show that HIIT is incredibly effective at ramping up fat burning and promoting sustainable weight loss. One review found that doing HIIT 3 times weekly for an average of 10 weeks significantly reduced body fat mass and waist circumference For an easy way to get started, try alternating between walking and jogging or sprinting for 30 seconds at a time. You can also cycle between exercises like burpees, pushups, or squats with short rest periods in between. HIIT may increase fat burning and help you expend more calories in a shorter period than other forms of exercise. Probiotics are a type of beneficial bacteria found in your digestive tract. In fact, these bacteria have been shown to play a role in everything from immunity to mental health Increasing your intake of probiotics through either food or supplements may also rev up fat burning and support long-term weight management. One review of 15 studies showed that people who took probiotics experienced significantly larger reductions in body weight, fat percentage, and BMI compared with those who took a placebo Another small study showed that taking probiotic supplements helped people following a high fat, high calorie diet stave off fat and weight gain Certain strains of probiotics in the genus Lactobacillus may be especially effective at aiding weight and fat loss Taking supplements is a simple, convenient way to get in a concentrated dose of probiotics every day. Alternatively, you can eat probiotic-rich foods like kefir, tempeh, natto, kombucha, kimchi, and sauerkraut. Taking probiotic supplements or increasing your intake of probiotic foods may help reduce body weight and fat percentage. Intermittent fasting is a diet pattern that involves cycling between periods of eating and fasting. Although it may not be a good fit for everyone, some research indicates that it may enhance both weight loss and fat loss. One review on intermittent fasting examined alternate-day fasting, a method in which you alternate between days of fasting and eating normally. Another small study showed that eating only during an 8-hour window each day helped decrease fat mass and maintain muscle mass when combined with resistance training Intermittent fasting has been shown to reduce body weight and body fat. It may also help preserve muscle mass when combined with resistance training. Studies suggest that gradual weight loss may be more beneficial for improving body composition and reducing body fat. Losing weight slowly may also reduce the risk of putting it back on again later 48, Both dietary strategies and exercise can help reduce belly fat. You lose fat when you take in fewer calories, or less energy, than you use. Exercise can help burn fat and either maintain or build muscle No foods will specifically enable you to burn belly fat, but you are less likely to continue gaining weight if you focus on fresh fruits and vegetables, healthy fats, and whole grains rather than highly processed foods with a lot of refined carbs and added sugar. Rather, you should incorporate healthy habits into your routine, such as eating whole grains instead of refined carbs, replacing sugary drinks with water, trying probiotics, or drinking coffee. Be sure to pair these simple nutrition tips with a well-rounded diet and active lifestyle to promote long-lasting, sustainable fat burning.

However, it only improves fat-burning capacity within the fat-burning zone itself—that is, at lower exercise intensities. Indeed, despite being well adapted for fat burning, elite male marathon runners oxidize carbohydrate almost exclusively during competition. Only slower marathon runners plus and ultramarathon runners are likely to benefit from emphasizing training in their fat-burning zone. In summary, there is probably nothing special you need to do with your diet or your training to become a fat-burning machine and, as such, a faster racer. Fat burning is a very popular and often-used term among endurance athletes. But is it really important to burn fat — and, if so, how can it best be achieved? Professor Asker Jeukendrup looks at what the research says. Fat burning is often associated with weight loss, decreases in body fat and increases in lean body mass, all of which can be advantageous for an athlete. It is known that well-trained endurance athletes have an increased capacity to oxidise fatty acids. This enables them to use fat as a fuel when their carbohydrate stores become limited. In contrast, patients with obesity, insulin resistance and type II diabetes may have an impaired capacity to oxidise fat. As a result, fatty acids may be stored in their muscles and in other tissues. This accumulation of lipid and its metabolites in the muscle may interfere with the insulin-signalling cascade and cause insulin resistance. It is therefore important to understand the factors that regulate fat metabolism, and the ways to increase fat oxidation in patients and athletes. Fats are stored mostly in subcutaneous adipose tissue, but we also have small stores in the muscle itself intramuscular triglycerides. At the onset of exercise, neuronal beta-adrenergic stimulation will increase lipolysis the breakdown of fats into fatty acids and glycerol in adipose tissue and muscle. Catecholamines such as adrenaline and noradrenaline may also rise and contribute to the stimulation of lipolysis. As soon as exercise begins, fatty acids are mobilised. Adipose tissue fatty acids have to be transported from the fat cell to the muscle, be transported across the muscle membrane and then be transported across the mitochondrial membrane for oxidation. The triglycerides stored in muscle undergo similar lipolysis and these fatty acids can be transported into the mitochondria as well. During exercise, a mixture of fatty acids derived from adipocytes and intramuscular stores is used. There is evidence that shows that trained individuals store more intramuscular fat and use this more as a source of energy during exercise 1. Fat oxidation is regulated at various steps of this process. Lipolysis is affected by many factors but is mostly regulated by hormones stimulated by catecholamines and inhibited by insulin. The transport of fatty acids is also dependent on blood supply to the adipose and muscle tissues, as well as the uptake of fatty acids into the muscle and into the mitochondria. By inhibiting mobilisation of fatty acids or the transport of these fatty acids, we can reduce fat metabolism. However, are there also ways in which we can stimulate these steps and promote fat metabolism? Exercise intensity — One of the most important factors that determines the rate of fat oxidation during exercise is the intensity. Although several studies have described the relationship between exercise intensity and fat oxidation, only recently was this relationship studied over a wide range of intensities 2. In absolute terms, carbohydrate oxidation increases proportionally with exercise intensity, whereas the rate of fat oxidation initially increases, but decreases again at higher exercise intensities see figure 1. So, although it is often claimed that you have to exercise at low intensities to oxidise fat, this is not necessarily true. However, the inter-individual variation is very large. However, very little research has been done. Recently we used this intensity in a training study with obese individuals. Compared with interval training, their fat oxidation and insulin sensitivity improved more after four weeks steady-state exercise three times per week at an intensity that equalled their individual Fatmax 4. Dietary effects — The other important factor is diet. A diet high in carbohydrate will suppress fat oxidation, and a diet low in carbohydrate will result in high fat oxidation rates. This effect of insulin on fat oxidation may last as long as six to eight hours after a meal, and this means that the highest fat oxidation rates can be achieved after an overnight fast. Endurance athletes have often used exercise without breakfast as a way to increase the fat-oxidative capacity of the muscle. Recently, a study was performed at the University of Leuven in Belgium, in which scientists investigated the effect of a six-week endurance training programme carried out for three days per week, each session lasting one to two hours 6. The participants trained in either the fasted or carbohydrate-fed state. When training was conducted in the fasted state, the researchers observed a decrease in muscle glycogen use, while the activity of various proteins involved in fat metabolism was increased. However, fat oxidation during exercise was the same in the two groups. It is possible, though, that there are small but significant changes in fat metabolism after fasted training; but, in this study, changes in fat oxidation might have been masked by the fact that these subjects received carbohydrate during their experimental trials. It must also be noted that training after an overnight fast may reduce your exercise capacity and may therefore only be suitable for low- to moderate- intensity exercise sessions. The efficacy of such training for weight reduction is also not known. Duration of exercise — It has long been established that oxidation becomes increasingly important as exercise progresses. During ultra-endurance exercise, fat oxidation can reach peaks of 1 gram per minute, although as noted in Dietary effects fat oxidation may be reduced if carbohydrate is ingested before or during exercise. In terms of weight loss, the duration of exercise may be one of the key factors as it is also the most effective way to increase energy expenditure. Mode of exercise — The exercise modality also has an effect on fat oxidation. Fat oxidation has been shown to be higher for a given oxygen uptake during walking and running, compared with cycling 7. The reason for this is not known, but it has been suggested that it is related to the greater power output per muscle fibre in cycling compared to that in running. Gender differences — Although some studies in the literature have found no gender differences in metabolism, the majority of studies now indicate higher rates of fat oxidation in women. In a study that compared men and women over a wide range of exercise intensities, it was shown that the women had higher rates of fat oxidation over the entire range of intensities, and that their fat oxidation peaked at a slightly higher intensity 8. The differences, however, are small and may not be of any physiological significance. There are many nutrition supplements on the market that claim to increase fat oxidation. These supplements include caffeine, carnitine, hydroxycitric acid HCA , chromium, conjugated linoleic acid CLA , guarana, citrus aurantium, Asian ginseng, cayenne pepper, coleus forskholii, glucomannan, green tea, psyllium and pyruvate. With few exceptions, there is little evidence that these supplements, which are marketed as fat burners, actually increase fat oxidation during exercise see table 1. One of the few exceptions however may be green tea extracts. The mechanisms of this are not well understood but it is likely that the active ingredient in green tea, called epigallocatechin gallate EGCG — a powerful polyphenol with antioxidant properties inhibits the enzyme catechol O-methyltransferase COMT , which is responsible for the breakdown of noradrenaline. This in turn may result in higher concentrations of noradrenaline and stimulation of lipolysis, making more fatty acids available for oxidation. Environment — Environmental conditions can also influence the type of fuel used. It is known that exercise in a hot environment will increase glycogen use and reduce fat oxidation, and something similar can be observed at high altitude. Similarly, when it is extremely cold, and especially when shivering, carbohydrate metabolism appears to be stimulated at the expense of fat metabolism. At present, the only proven way to increase fat oxidation during exercise is to perform regular physical activity. Exercise training will up-regulate the enzymes of the fat oxidation pathways, increase mitochondrial mass, increase blood flow, etc. Research has shown that as little as four weeks of regular exercise three times per week for minutes can increase fat oxidation rates and cause favourable enzymatic changes However, too little information is available to draw any conclusions about the optimal training programme to achieve these effects. In one study we investigated maximal rates of fat oxidation in subjects with varying fitness levels. In this study, we had obese and sedentary individuals, as well as professional cyclists 9. VO2max ranged from Interestingly, although there was a correlation between maximal fat oxidation and maximal oxygen uptake, at an individual level, fitness cannot be used to predict fat oxidation. What this means is that there are some obese individuals that have similar fat oxidation rates to professional cyclists see figure 2! The large inter-individual variation is related to factors such as diet and gender, but remains in large part unexplained. Fat burning is often associated with weight loss, decreases in body fat and increases in lean body mass. However, it must be noted that such changes in body weight and body composition can only be achieved with a negative energy balance: you have to eat fewer calories than you expend, independent of the fuels you use! The optimal exercise type, intensity, and duration for weight loss are still unclear. Current recommendations are mostly focused on increasing energy expenditure and increasing exercise volumes. Finding the optimal intensity for fat oxidation might aid in losing weight fat loss and in weight maintenance, but evidence for this is currently lacking. It is also important to realise that the amount of fat oxidised during exercise is only small. Fat oxidation rates are on average 0. So in order to oxidise 1kg of fat mass, more than 33 hours of exercise is required! The duration of exercise, however, plays a crucial role, with an increasing importance of fat oxidation with longer exercise. Of course, this also has the potential to increase daily energy expenditure. If exercise is the only intervention used, the main goal is usually to increase energy expenditure and reduce body fat. When combined with a diet programme, however, it is mainly used to counteract the decrease in fat oxidation often seen after weight loss Higher fat oxidation rates during exercise are generally reflective of good training status, whereas low fat oxidation rates might be related to obesity and insulin resistance. The vast majority of nutrition supplements do not have the desired effects. Currently, the only highly effective way to increase fat oxidation is through exercise training, although it is still unclear what the best training regimen is to get the largest improvements. Finally, it is important to note that there is a very large inter-individual variation in fat oxidation that is only partly explained by the factors mentioned above. This means that although the factors mentioned above can influence fat oxidation, they cannot predict fat oxidation rates in an individual.

Conversely, diets high in whole grains are tied to a lower body mass index BMI and body weight, plus a smaller waist circumference Aim to replace refined carbs from pastries, processed foods, pastas, white breads, and breakfast cereals with whole grains like whole wheat, quinoa, buckwheat, barley, and oats.

Cardio, also known as aerobic exercise, is one of the most common forms of exercise. Adding cardio to your routine may be one of the most effective ways to enhance fat burning and weight loss.

For example, one review of 15 studies tied increased aerobic exercise to decreased belly fat in middle-age women Other studies have found that aerobic exercise may increase muscle mass and decrease belly fat, waist circumference, and body fat 32 , 33 , Most research recommends — minutes of moderate to vigorous exercise per week, or roughly 20—40 minutes of cardio each day Running, walking, cycling, and swimming are just a few examples of cardio workouts.

Studies show that the more aerobic exercise people get, the more body fat they tend to lose. Cardio may also help reduce waist circumference and increase muscle mass. The caffeine in coffee stimulates your central nervous system, increases metabolism, and boosts the breakdown of fatty acids Caffeine has also been shown to enhance fat burning during aerobic exercise, particularly for those who are untrained or sedentary One large review of 12 studies associated increased coffee intake with a lower risk of obesity, especially for men.

Another study including 2, people linked higher caffeine intake to a higher rate of success with weight loss maintenance 38 , To maximize the health benefits of coffee, avoid adding large amounts of cream and sugar. Instead, enjoy it black or with a small splash of milk.

Coffee contains caffeine, which may boost metabolism and fat breakdown. Studies suggest that high caffeine intake may aid weight loss. High intensity interval training HIIT is a form of exercise that pairs quick bursts of activity with short recovery periods to keep your heart rate elevated.

Studies show that HIIT is incredibly effective at ramping up fat burning and promoting sustainable weight loss. One review found that doing HIIT 3 times weekly for an average of 10 weeks significantly reduced body fat mass and waist circumference For an easy way to get started, try alternating between walking and jogging or sprinting for 30 seconds at a time.

You can also cycle between exercises like burpees, pushups, or squats with short rest periods in between. HIIT may increase fat burning and help you expend more calories in a shorter period than other forms of exercise.

Probiotics are a type of beneficial bacteria found in your digestive tract. In fact, these bacteria have been shown to play a role in everything from immunity to mental health Increasing your intake of probiotics through either food or supplements may also rev up fat burning and support long-term weight management.

One review of 15 studies showed that people who took probiotics experienced significantly larger reductions in body weight, fat percentage, and BMI compared with those who took a placebo Another small study showed that taking probiotic supplements helped people following a high fat, high calorie diet stave off fat and weight gain Certain strains of probiotics in the genus Lactobacillus may be especially effective at aiding weight and fat loss Taking supplements is a simple, convenient way to get in a concentrated dose of probiotics every day.

Alternatively, you can eat probiotic-rich foods like kefir, tempeh, natto, kombucha, kimchi, and sauerkraut. Taking probiotic supplements or increasing your intake of probiotic foods may help reduce body weight and fat percentage.

Intermittent fasting is a diet pattern that involves cycling between periods of eating and fasting. Although it may not be a good fit for everyone, some research indicates that it may enhance both weight loss and fat loss.

One review on intermittent fasting examined alternate-day fasting, a method in which you alternate between days of fasting and eating normally. Another small study showed that eating only during an 8-hour window each day helped decrease fat mass and maintain muscle mass when combined with resistance training Intermittent fasting has been shown to reduce body weight and body fat.

It may also help preserve muscle mass when combined with resistance training. Studies suggest that gradual weight loss may be more beneficial for improving body composition and reducing body fat.

Losing weight slowly may also reduce the risk of putting it back on again later 48, Both dietary strategies and exercise can help reduce belly fat.

You lose fat when you take in fewer calories, or less energy, than you use. Exercise can help burn fat and either maintain or build muscle No foods will specifically enable you to burn belly fat, but you are less likely to continue gaining weight if you focus on fresh fruits and vegetables, healthy fats, and whole grains rather than highly processed foods with a lot of refined carbs and added sugar.

Rather, you should incorporate healthy habits into your routine, such as eating whole grains instead of refined carbs, replacing sugary drinks with water, trying probiotics, or drinking coffee. Be sure to pair these simple nutrition tips with a well-rounded diet and active lifestyle to promote long-lasting, sustainable fat burning.

Aim of work This review will focus on the recent advances in fat burning supplements, fat burning foods, and fat flash diet.

Conclusion The human body can act as a fat-burning machine by depending on low-calorie foods instead of high-calorie foods in addition to doing regular exercise, avoiding toxins and processed food, and applying any fat flush dietary program under the approval of a professional doctor.

Background Adipose tissue is a loose connective tissue composed of adipocytes and is responsible for storing energy in the form of lipids; at the same time, it cushions and insulates the body Birbrair et al.

Adipose tissue The adipose tissue is a loose connective tissue full of adipocytes. Structure of adipose tissue The very important God-given cellular components are found in adipose tissue in two different forms: white adipose tissue WAT and brown adipose tissue BAT Fig.

Fat burners When we talk about fat loss, much of the information available can be confusing. Fat-burning supplements The list of supplements that claimed to increase or improve fat metabolism is long. Classes of supplements In this review, the evidence for some of these supplements is briefly summarized.

Energy enhancers 1. Protein and amino acids products 1. Testosterone enhancers 1. Lean body enhancers 1. Miscellaneous 1. Fat burning supplements safety Some authorities claim that these supplements can safely be used in small amounts and they can be effective at jump-starting weight loss.

Macronutrients There are three macro-nutrients that can be present in food: fat, protein, and carbohydrate. Fats: the good, the bad, and the ugly Fat is an important nutrient for health and plays many different roles in the body. The ugly: trans fats They are made from a chemical process known as partial hydrogenation; this is when liquid oil is made into solid fat.

How does fat burn fat? Fat-burning natural foods, rich in good fats Good fats help in burning body fat, not to feel hungry, enhance metabolism, and stimulate certain hormones that have many functions within the body. How does protein burn fat?

Mechanism 2: Stimulates growth hormone release Protein stimulates growth hormone GH release from the anterior pituitary. Mechanism 3: Increases protein synthesis Protein provides the building blocks of body tissues and regular consumption of it, i.

Mechanism 4: Boosts metabolism Not only does protein promote greater energy expenditure by maintaining an elevated metabolic rate but it also boosts the metabolism because it requires more energy to be digested compared to the other macronutrients, carbohydrate, and fat.

Mechanism 5: Suppresses appetite Protein has powerful appetite suppressing effects, especially compared to the other macronutrients. Fat-burning foods, rich in proteins From the aforementioned 5 mechanisms, it is easy to conclude why protein can help promote fat burning in the body.

Micronutrients Calcium Several studies have correlated higher calcium intakes with lower body weight or less weight gain over time Parikh et al. Vitamin D Observational studies indicate that greater body weights are associated with lower vitamin D status, and obese individuals frequently have marginal or deficient circulating levels of vitamin D Lim et al.

Other fat-burning foods 1. Water It would not count as food because it has no calories. The link between weight gain, weight loss, and toxins The ingested and the environmental toxins that were taken every day can be stored in fat cells.

Fat flush diet detox diet Fat flush is a low-carbohydrate eating plan devised with a focus on weight loss while detoxing the liver and lymphatic systems to enhance overall health.

The function of fat flush plan It aims to cleanse the liver, improve wellness, and produce weight loss. Conclusion We can turn our body into fat-burning machine by including low-calorie foods instead of high-calorie foods in our diet.
