Speed up metabolism naturally -

Protein, for example, may be more likely than carbohydrates or fat to promote thermogenesis, the burning of calories in the body. Those who consumed a higher proportion of protein burned more energy than those who consumed less. Some research has suggested that green tea extract may play a role in promoting fat metabolism.

While the Academy of Nutrition and Dietetics says any increase is likely to be small, green tea may help manage weight and health in other ways.

The National Center for Complementary and Integrative Health says it is safe to consume up to 8 cups of green tea a day. People should speak with a doctor before increasing their intake of green tea or consuming it during pregnancy. It may interact with some medications.

During pregnancy, it may increase the risk of birth defects due to low folic acid levels. Does green tea help with weight loss? The authors of a small study found that combining resistance training with dietary measures led to a slight increase in metabolic rate, but it was not statistically significant.

Participants who did only resistance training saw a reduction in fat mass and an increase in lean mass. Research suggests that when a person has more muscle mass, their body uses food for energy more effectively.

In other words, their metabolism is less wasteful. The researchers suggested that fat free mass lean mass and thyroid hormone levels might help account for the variability. Resistance training may involve lifting weights and doing exercises that use the weight of the body or resistance bands to build muscle.

A previous study , from , found that high intensity interval resistance training also increased metabolic rate. Interval training is highly intensive and may be more suitable for people who are already fit than those who are new to regular exercise.

How can exercise help you build muscle? Staying hydrated is essential for the body to function at its best. Water is necessary for optimal metabolism, and it may help a person lose weight.

In , scientists assessed the metabolic rate of 13 people who consumed either or milliliters ml of water. They found evidence of increased fat oxidation after ml when a person is at rest, and concluded that drinking water may have an impact on metabolism. However, they did not find that it increased metabolic rate.

This may happen because the additional water helps the body burn fat preferentially over carbohydrate. How much water should I drink each day? Stress affects hormone levels, and it can cause the body to produce more cortisol than usual. Cortisol is a hormone that helps regulate appetite.

In , researchers found unusually high cortisol levels in people with disordered eating. The body releases cortisol in times of stress. However, the authors of a small study found no evidence linking resting metabolic rate and anxiety.

Stress could also have an indirect impact by affecting eating patterns and sleep, both of which can alter the rate of metabolism. Why does stress happen, and how can I manage it? People who have less sleep may have a lower metabolic rate, according to research from The study took place in a sleep laboratory, and participants slept 4 hours per night for 5 nights followed by one night of 12 hours sleep.

Their metabolic rate fell after the nights with little sleep but returned to their usual levels after the night of recovery sleep. The authors believed the body reduces metabolic rate to conserve energy when a person sleeps less.

They noted this could lead to weight gain in people who do not get enough sleep. The need for sleep varies between individuals, but the Centers for Disease Control and Prevention CDC recommend that adults aged 18—60 should have at least 7 hours per night.

What should you do if you have trouble sleeping? The results of a rodent experiment from suggested that a low intake of various B vitamins could impact the rate at which the body metabolizes lipids, including cholesterol and triglycerides. More research may be needed to understand the relationship between vitamins, metabolism, and weight loss.

A complete guide to B vitamins, types, sources, and more. Some research has suggested that eating spices such as chili, which contains capsaicin, can increase metabolic rate, including the rate at which the body burns fat and uses energy.

Healthcare providers sometimes recommend this strategy to help people manage obesity. While medical literature has shown snacking provides some benefits for certain people, like athletes, there is little evidence of a direct metabolic effect. If you snack, choose nutrient-dense options over foods like cookies, chips, and those with added salts and sugars.

The healthiest snacks are nuts, fresh fruit, and vegetables. Additional ways to boost your metabolism include being active, avoiding crash diets, and reducing stress. Having a sedentary lifestyle can adversely affect your health. It raises the risk of obesity, affects bone and muscle development, and impacts your metabolism.

If you sit for work or are constantly seated at home, take breaks to stand or walk. One study comparing data from Southeast Asia and the United States showed that taking a break to stand or walk every 30 minutes boosted metabolic health in older adults. Countless dietary fads promise to boost your metabolism and manage your weight.

Crash diets focusing on severe food restrictions can prevent your body from getting the nutrients it needs. Aim to eat a variety of foods that provide sufficient calories and essential vitamins and minerals. Blood flow and energy expenditure are redirected from digestion and metabolism to the muscles and the brain.

This slows your metabolic rate, and if the stress persists, this can cause long-term effects. So how can you tell if your metabolism is slow? There can be many signs, with the most common including:.

The thyroid is the small, butterfly-shaped gland in your neck that regulates metabolism. Low thyroid levels slow your metabolic function and raise the risk of complications, such as high cholesterol or coma.

A big part of managing hypothyroidism and preventing these complications is boosting your metabolic rate. Alongside a prescription of levothyroxine , a synthetic thyroid hormone, lifestyle and dietary changes that promote your metabolism play a key role.

Metabolism is the process by which your body converts food into energy. Modifiable factors influencing your metabolic rate include diet, physical activity, and sleep. Incorporating a high-protein diet, high-intensity exercise, strengthening, and better sleep habits are among the ways to boost your metabolism naturally.

Effect of 'water induced thermogenesis' on body weight, body mass index and body composition of overweight subjects. J Clin Diagn Res. One way to nudge the metabolism needle is to change the amount of some cell types by building more lean mass or muscle.

More muscle means more metabolically demanding muscle cells, which translates into a higher resting metabolism. Individual differences in this mass underlie most of the variation in metabolism from person to person, according to Urlacher.

Two people with the same body weight but different proportions of lean mass to fat can eat the same number of calories and still have different weight-gain outcomes. In terms of weight loss, the timing of a gym visit also might make a tiny difference, Urlacher says.

A resting heart rate of 50 beats per minute for one person versus 70 for another just means the heart with the slower resting rate might be more efficient at getting oxygen to tissues, Pontzer says.

Bumping up an exercise regimen to burn through more calories may also seem like a sure way to boost metabolism and lose weight. Evidence suggests instead that daily energy expenditure has a boundary.

If you try to push past this boundary, the body adjusts metabolic expenditure in other activities to get back inside the lines. This energy compensation may explain why simply adding more miles a week can yield fitness and other gains but has little effect on weight. People who exercise also tend to increase caloric intake to compensate for the additional energy expenditure.

But how might metabolism change if you exercise and restrict caloric intake?
