Thermogenesis and metabolic disorders -

Pair that with the fact that diet-induced thermogenesis has been found in studies to be higher in the morning than the evening, and it may lend credibility to why those who eat earlier in the day and participate in biohacking modalities like a morning cold plunge see favorable body composition changes - it may be due to an amplified diet-induced thermogenic response.

The following functional medicine labs can be utilized to assess areas that contribute to diet-induced thermogenesis:. Since adequate digestion and absorption are central to diet-induced thermogenesis, it can be helpful to evaluate the health and function of the GI digestive system through a comprehensive digestive stool analysis.

A healthy gut produces all of the necessary enzymes and compounds needed to digest food, activate brown adipose tissue, and increase metabolic rate in response to the diet; without adequate production of, for example, bile acids, the diet-induced thermogenic response described above may not be as optimal.

Since thyroid function helps modulate thermogenesis as a whole, in addition to the activation of brown adipose tissue, it can be helpful to assess if one's thyroid is working optimally. There's also a close link between thyroid function and bile acids, meaning a full thyroid panel can help provide insight into the bigger picture of how well the metabolic pathways underlying diet-induced thermogenesis are functioning.

Understanding your body fat percentage and the amount of muscle mass you have can be helpful when considering your total daily energy expenditure, calculating the amount of protein and other macronutrients in your diet, and ensuring any weight loss efforts are producing loss of body fat rather than valuable muscle mass.

The ideal nutritional approach to improve thermogenesis would be a diet that meets protein needs or protein-forward nutrition. While many "diets" fit the bill, the diet likely to lead to the highest rate of diet-induced thermogenesis would be a higher protein diet. Adding in foods such as capsaicin cayenne pepper and green tea may also be helpful, and choosing primarily whole food sources of fats and carbohydrates versus processed foods would be ideal.

Many supplements are labeled "thermogenic aids" or "fat burners," with a few ingredients in common that may improve thermogenesis. However, it's critical to note that many of these supplements marketed as " fat burners " contain amounts far beyond a "single" serving of a given compound and are not well-regulated regarding safety and efficacy.

Below are several supplements supported by literature regarding their impact on thermogenesis. Green tea extract and its catechin content have been linked to increases in energy expenditure and thermogenesis, as well as increased fat oxidation. While some studies suggest that any thermogenic aid has a risk of increased heart rate and blood pressure, green tea extract is one of the safest aids, with a daily intake of mg or less in a supplemental form deemed safe.

Caffeine intake has been linked to increased thermogenesis and brown adipose tissue activation. However, many "thermogenic aid" supplements have high amounts of caffeine, up to four times the amount you'd get from drinking one cup of coffee.

Higher caffeine intake also increases the risk of short-term elevated heart rates, palpitations, blood pressure, and anxiety. For those with higher cardiovascular risk, caffeine may not be the best thermogenic aid to consider. Capsaicin supplements have been linked to weight loss through the effect of capsaicin on thermogenesis.

However, the impact may be seen more in lean individuals, as studies have shown inconsistent results in obese populations. Up to 6mg taken daily for 12 weeks has been shown to have favorable effects on body composition, especially when paired with a healthy diet and exercise plan.

In addition to diet composition, studies also show that eating slowly and ensuring that you're chewing your food thoroughly helps to increase the rate of diet-induced thermogenesis. So if you're working on a body composition goal, make sure you're taking the time to pause, slow down, and intentionally chew your meal.

This helps with the digestive process and production of enzymes and hormones important for digestion and translates to expending more calories while digesting your food. Diet-induced thermogenesis refers to the impact your food and digestion can have on the calories expended each day.

The amount of brown adipose tissue BAT one has can correlate with more efficient diet-induced thermogenesis, and diets higher in protein tend to impart a higher percentage of diet-induced thermogenesis to total daily energy expenditure, making them ideal for those looking to lose body fat percentage.

Last, diet-induced thermogenesis is more efficient earlier in the day than at night, which is an important consideration for meal timing and planning as part of a larger holistic approach to one's nutrition.

Importantly, both brown and beige fat cells can impact nutrient homeostasis even independently of its impact on energy expenditure. This point is critical, as it dispels the notion that BAT is merely a heat generator. Several important areas of investigation in the field of BAT biology relate to cardiometabolic disease.

Rapidly emerging functions and areas of study in BAT biology incite multiple tissues and processes. For example, neuronal and immune signaling exert a regulatory effect on brown fat cells, cold temperatures induce de novo brown adipocyte differentiation, and substrates beyond glucose can fuel thermogenesis.

Brown fat cells also exert control over endocrine functioning and show heterogeneity with specific metabolic activity. Moreover, WAT can respond to cold temperatures by remodeling to a BAT-like phenotype. While UCP1 generates heat by disruption of the mitochondrial inner membrane electrochemical gradient, UCP1-independent mechanisms that fueling adipocyte thermogenesis also exist.

Understanding the interplay between these systems may lead to strategies for harnessing the power of BAT in the treatment for human metabolic disease. In parallel to the studies of rodent thermogenic adipose tissue, efforts to understand the importance of BAT in humans have continued.

Notably, Becher et al. determined that the presence of BAT in adult humans is linked to the incidence of cardiometabolic disease 9.

Individuals with detectable BAT had lower prevalence of type 2 diabetes, dyslipidemia, congestive heart failure, and hypertension, across different ranges of BMI. This observation is exciting as it supports the hypothesis that BAT can regulate cardiometabolic health, even independent of its potential effect on body weight.

Nevertheless, correlation, of course, does not equal causation. As such, the physiological importance of BAT in adult humans and the potential contribution of BAT dysfunction to the development of metabolic disease has remained a topic of great discussion.

In June of , organizers of the annual meeting of the Endocrine Society ENDO staged a live debate, where leading investigators in the study of human BAT offered their perspectives on the burning question of whether human BAT is a viable target for treatment of cardiometabolic disease.

In this issue of the JCI , these same investigators expand on the discussion, highlighting the challenges Carpentier and Blondin and promise Cypess of human BAT as a therapeutic target 10 , Carpentier and Blondin question the physiological importance of human BAT during acute cold exposure, as the amount of BAT is relatively small in comparison with rodents and cold exposure invokes a multi-organ response e.

Moreover, they raised concerns as to whether 18 F-FDG uptake truly reflects BAT thermogenesis, particularly in older or diabetic subjects, arguing that glucose uptake and metabolism may not be directly coupled to thermogenesis.

As such, they question whether there is sufficient evidence that BAT dysfunction contributes to development of metabolic disease. Substrate preference for BAT thermogenesis has been a topic of discussion.

The development of improved stable isotope tracing techniques is now enabling investigators to elegantly trace nutrient fate and identify critical fuels of thermogenesis in adipocytes 12 , Emanating from these emerging studies is an appreciation of the flexibility of brown adipocytes with respect to fuel selection and the importance of nutritional state fed versus fasted in determining the preferred fuel choice Multiple factors may influence substrate utilization in BAT.

Diurnal BAT activity may be an important factor to consider when studying the therapeutic potential of promoting BAT activity. Other additional experimental factors may need to be considered in the study of BAT thermogenic activity, such as the duration of cold exposure. Cypess remains optimistic about the potential of pharmacological BAT activation to drive improvements in glucose and lipid homeostasis.

Treatment of individuals with the FDA-approved β3-adrenergic receptor agonist, mirabegron, leads to an estimated doubling of BAT mass, increased energy expenditure, increased insulin sensitivity and insulin secretion, and elevated HDL Increasing energy expenditure did not ultimately impact fat mass and body weight, perhaps due compensatory changes in food intake.

Cypess acknowledges that activating BAT as a therapeutic for obesity is likely a big challenge; however, BAT activation through this mechanism may help in the treatment of glucose and lipid disorders.

The choice of utilizing β3-adrenergic receptor agonists to activate BAT is logical. In mice, pharmacological activation of this receptor drives brown adipocyte activation and a substantial degree of energy expenditure. Nevertheless, there are still some limitations to this approach as a tool to study the potential of BAT.

First, both white and brown adipocytes express the β3-adrenergic receptor. It is thus difficult to formally ascribe the beneficial effects of mirabegron solely to its direct action on BAT.

Moreover, β3-adrenergic receptor agonism may not maximally activate BAT thermogenesis in humans. The thermogenic potential of this tissue may thus be underestimated. In fact, human brown adipocytes appear to be more responsive to β2-adrenergic receptor agonism Moreover, the natural response of BAT to cold exposure is not entirely mimicked by agonism of adipocyte β-adrenergic receptors.

In fact, β-adrenergic receptor—independent mechanisms enhancing BAT thermogenesis exist Cold induces a notable remodeling of adipose tissue, including changes in immune cell composition and vascular remodeling Immune cell—derived signals, in turn, amplify the effects of catecholamines on thermogenic gene activation.

As such, the identification of new strategies to better mimic the wide-ranging effects of cold exposure on brown fat tissue — not just mature adipocytes — may enable investigators to test the true potential of this tissue.

Both Carpentier and Cypess agree on one important issue. If the abundance of functional thermogenic fat tissue can be increased in humans, then the chance of a therapeutic benefit is more likely.

Since , several advances have been made in our understanding of the developmental origins of brown adipocytes and the identity of their progenitor cells in adulthood. The natural capacity of white adipocytes to activate a thermogenic phenotype is highlighted by the browning of WAT depots that occurs in humans suffering from severe burns or in those with pheochromocytomas 20 , Advancements in the technology supporting cell-based therapies and organoid development may make it possible to leverage our knowledge of adipocyte development for therapeutic benefit.

Ultimately, successful translation of any approach to the clinic will depend on how putative BAT therapeutics stack up against current medicinal approaches. Emerging incretin-based therapies are proving to be effective for the treatment of obesity and diabetes 22 ; however, not all will benefit from these drugs for various reasons and there is room for complementary approaches.

For example, one can envision leveraging adipose thermogenesis as means to help maintain weight loss. Our understanding of BAT biology continues to increase at an exciting and rapid pace. The physiological importance of BAT in humans remains unclear, as is whether BAT dysfunction is part of the underlying problem leading to aspects of cardiometabolic disease.

Nevertheless, adipose thermogenesis does not have to be part of the problem for it to be part of the solution.

Patience and careful and rigorous science will be needed to fully understand if and how the emerging concepts in the field can be leveraged for the development of therapeutic strategies.

Nevertheless, obesity is a preventable risk factor in cancer. Lifestyle interventions might contribute to reduce the adverse effects of obesity.

Thus, Mediterranean diet interventional studies have been shown to reduce to circulation inflammatory factors, insulin sensitivity and cardiovascular function, with durable responses of up to 2 years in obese patients. Mediterranean diet supplemented with extra-virgin olive oil reduced the incidence of breast cancer compared with a control diet.

Physical activity is another important lifestyle factor which may also contribute to reduced systemic biomarkers of metabolic syndrome associated to obesity. In this scenario, precision nutrition may provide complementary approaches to target the metabolic inflammation associated to "unhealthy obesity".

Herein, we first describe the different types of adipose tissue -thermogenic active brown adipose tissue BAT versus the energy storing white adipose tissue WAT. More specifically, we focus on two axis: 1 the activation of thermogenesis in BAT and browning of WAT; 2 and the potential of augmenting the oxidative capacity of muscles to dissipate energy.

These strategies may be particularly relevant as complementary approaches to alleviate obesity associated effects on chronic inflammation, immunosuppression, angiogenesis and chemotherapy resistance in cancer.

Finally, we summarize main studies where plant derived extracts, mainly, polyphenols and flavonoids, have been applied to increase the energy expenditure. Keywords: bioactive compounds; metabolic diseases; precision nutrition; thermogenesis.

JavaScript is disabled	This gland secretes hormones to regulate many metabolic processes, including energy expenditure the rate at which kilojoules are burned. Thyroid disorders include:. Our genes are the blueprints for the proteins in our body, and our proteins are responsible for the digestion and metabolism of our food. Sometimes, a faulty gene means we produce a protein that is ineffective in dealing with our food, resulting in a metabolic disorder. In most cases, genetic metabolic disorders can be managed under medical supervision, with close attention to diet. The symptoms of genetic metabolic disorders can be very similar to those of other disorders and diseases, making it difficult to pinpoint the exact cause. See your doctor if you suspect you have a metabolic disorder. Some genetic disorders of metabolism include:. This page has been produced in consultation with and approved by:.

Two processes of metabolism Metabolic rate Metabolism and age-related weight gain Hormonal disorders of metabolism Genetic disorders of metabolism Where to get help. Two processes of metabolism Our metabolism is complex — put simply it has 2 parts, which are carefully regulated by the body to make sure they remain in balance. They are: Catabolism — the breakdown of food components such as carbohydrates , proteins and dietary fats into their simpler forms, which can then be used to provide energy and the basic building blocks needed for growth and repair. Anabolism — the part of metabolism in which our body is built or repaired. Anabolism requires energy that ultimately comes from our food. When we eat more than we need for daily anabolism, the excess nutrients are typically stored in our body as fat. Thermic effect of food also known as thermogenesis — your body uses energy to digest the foods and drinks you consume and also absorbs, transports and stores their nutrients. Energy used during physical activity — this is the energy used by physical movement and it varies the most depending on how much energy you use each day. Physical activity includes planned exercise like going for a run or playing sport but also includes all incidental activity such as hanging out the washing, playing with the dog or even fidgeting! Basal metabolic rate BMR The BMR refers to the amount of energy your body needs to maintain homeostasis. Factors that affect our BMR Your BMR is influenced by multiple factors working in combination, including: Body size — larger adult bodies have more metabolising tissue and a larger BMR. Amount of lean muscle tissue — muscle burns kilojoules rapidly. Crash dieting, starving or fasting — eating too few kilojoules encourages the body to slow the metabolism to conserve energy. Age — metabolism slows with age due to loss of muscle tissue, but also due to hormonal and neurological changes. Growth — infants and children have higher energy demands per unit of body weight due to the energy demands of growth and the extra energy needed to maintain their body temperature. Gender — generally, men have faster metabolisms because they tend to be larger. Genetic predisposition — your metabolic rate may be partly decided by your genes. Hormonal and nervous controls — BMR is controlled by the nervous and hormonal systems. Hormonal imbalances can influence how quickly or slowly the body burns kilojoules. Environmental temperature — if temperature is very low or very high, the body has to work harder to maintain its normal body temperature, which increases the BMR. Infection or illness — BMR increases because the body has to work harder to build new tissues and to create an immune response. Amount of physical activity — hard-working muscles need plenty of energy to burn. Regular exercise increases muscle mass and teaches the body to burn kilojoules at a faster rate, even when at rest. Drugs — like caffeine or nicotine , can increase the BMR. Dietary deficiencies — for example, a diet low in iodine reduces thyroid function and slows the metabolism. Thermic effect of food Your BMR rises after you eat because you use energy to eat, digest and metabolise the food you have just eaten. Hot spicy foods for example, foods containing chilli, horseradish and mustard can have a significant thermic effect. Energy used during physical activity During strenuous or vigorous physical activity, our muscles may burn through as much as 3, kJ per hour. Metabolism and age-related weight gain Muscle tissue has a large appetite for kilojoules. Hormonal disorders of metabolism Hormones help regulate our metabolism. Thyroid disorders include: Hypothyroidism underactive thyroid — the metabolism slows because the thyroid gland does not release enough hormones. Some of the symptoms of hypothyroidism include unusual weight gain, lethargy, depression and constipation. Hyperthyroidism overactive thyroid — the gland releases larger quantities of hormones than necessary and speeds the metabolism. Some of the symptoms of hyperthyroidism include increased appetite, weight loss, nervousness and diarrhoea. Genetic disorders of metabolism Our genes are the blueprints for the proteins in our body, and our proteins are responsible for the digestion and metabolism of our food. Some genetic disorders of metabolism include: Fructose intolerance — the inability to break down fructose, which is a type of sugar found in fruit, fruit juices, sugar for example, cane sugar , honey and certain vegetables. Galactosaemia — the inability to convert the carbohydrate galactose into glucose. Galactose is not found by itself in nature. Thus, Mediterranean diet interventional studies have been shown to reduce to circulation inflammatory factors, insulin sensitivity and cardiovascular function, with durable responses of up to 2 years in obese patients. Mediterranean diet supplemented with extra-virgin olive oil reduced the incidence of breast cancer compared with a control diet. Physical activity is another important lifestyle factor which may also contribute to reduced systemic biomarkers of metabolic syndrome associated to obesity.
