This review is an effort to summarize the role of MMetabolism burning supplements, fat burning foods, and fat flash diet to support the physiological fatt of fat metaolism. The adipose metabo,ism is a Metabolis, connective tissue full of Metabolism and fat cell metabolism.

It is cel for storing fats in the form of triglycerides. It is found all over the body: under the Metabolism and fat cell metabolism subcutaneous fatmetabklism around internal Metabolizm visceral fat far, between muscles, within the bone marrow, and in the breast tissue Nagai et al.

Men tend to store more visceral fat around their internal organsleading to obesity around the middle of their abdomen belly fat Cannon et al.

However, women tend to store more subcutaneous fat within the buttocks and thighs Brown et al. These differences are due to the sex hormones produced by males and females Canoy 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.

The presence, amount, and distribution of each vary depending on the species. WAT is the most common and is the fats that many of us complain of acquiring Divoux et al. It is found meetabolism the waists and thighs, while BAT is mainly found around the neck areas front and back and supraclavicular regions Harms et al.

WAT serves three functions: heat insulation, mechanical cushion, and a source of energy Alligier et al. BAT serves to generate body heat. It derives its color from rich vascularization and densely packed iron-containing mitochondria. Instead of serving as a substrate, the lipid in BAT releases energy directly znd heat, therefore it used in heat production for non-shivering thermogenesis and for utilization of excess caloric intake via diet-induced thermogenesis Kissig et al.

The mechanism of heat generation is related to the metabolism of the mitochondria. Mitochondria from BAT have a specific carrier known as uncoupling protein that transfers protons from outside to inside without subsequent production of ATP Enerbäck Everyone does not carry their adipose tissue in the same anatomical locations.

Adipose tissue that is located in the upper body has been termed apple distribution and meyabolism distribution pattern is found more in men while adipose tissue that is accumulated in the lower body has been termed pear distribution and this distribution pattern is found more in women Karastergiou et al.

A primary factor is genetic background, which can be seen by looking at the similarity in fat distribution within same-sex family members. As mentioned above, gender is also known to affect body fat location.

After the menopause, a change towards upper body fat distribution is observed due to a decrease in hormone lipoprotein lipase LPL activity in the lower body region Inagaki et al.

Upper body fat distribution is correlated with the development of various health problems, including cardiovascular disease, hypertension, diabetes, sleep apnea syndrome, osteoarthritis, and some cancers as most of fats are packed around the internal organs Metabolismm et al. Lower body fat distribution is correlated with the mechanical problems as most of fats are distributed around the hips, thighs and buttocks Dhaliwal and Welborn Calculation of metabklism is a quick test to predict the risk for complications associated with upper-body fat distribution.

Women are at risk if the ratio exceeds 0. Weight cycling is defined as a repeated pattern of losing and regaining body weight. The main causes of it are metbolism weight rapidly, not exercising and bad eating habits Brownell It leads to obesity-related problems, such as high cholesterol, high blood pressure, increased risk for heart disease, and negative blood flow to the heart leading meetabolism plaque buildup in the arteries and potentially leads to stroke or heart attacks Metabolsim et al.

Lipogenesis is the process of fat deposition that occurs in the liver and adipose tissue Kersten Carbohydrate and protein consumed in diet can be converted to fat. The carbohydrates can be stored as glycogen in the liver and muscle and can be also converted to triglycerides in the liver and transferred to adipose tissue for storage.

Amino acids are used for new protein synthesis or they can be converted to carbohydrates and fat Wood et al. Brown fat tissue in the body can burn huge amounts of energy to generate heat, and studies in humans and animals have suggested that increasing the amount of healthy brown fat might help weight management.

However, how to safely and effectively increase brown fat has been a significant challenge for researchers Virtanen et al. The activity of this tissue changes over time: It decreases with age, just as it does in obese individuals and diabetics.

Hence, ways to heat-up thermogenesis in brown fat are being sought which can be used to prevent obesity and diabetes Kissig et al. A simple, innovative tissue-grafting strategy that increases endogenous brown fat has been developed. The method directly converted white fat to brown fat outside the body and then re-implanted it in a patient.

They then used their methods on human subcutaneous fat and were able to effectively convert it to brown fat. This suggests that it might be possible one day to attempt this approach in humans as a potential therapy to help with weight loss, control of blood glucose levels, or to prevent weight gain Nordqvist et al.

Other methods to increase anx fat include chronic cold exposure, which is uncomfortable for most people, and pharmaceuticals that can cause side effects by targeting other organs. In a study carried out on volunteers with higher brown fat levels, volunteers started shivering at lower temperatures compared to those with lower levels.

These volunteers burned an extra calories, a 1. They not only experience an increase in the heat output of brown fat in the cold as they got used to the lower temperatures but also an improvement in the control of blood sugar via insulin Merabolism et al.

Adipose tissue is now known to be a very important and active endocrine organ Coelho et al. It is well established that adipocytes, play a vital role in the storage and release of energy throughout the human body.

A number of different hormones are released from the adipose tissue and these are responsible for different functions within the body Fig. Adipose tissue secretes cytokines like TNF-α, IL-6, and IL-1β, which are involved in sending messages between cells Coelho et al.

Most people really do not know how the fat cells work, how the fat burning process takes place, or where the fat goes when it is burned. It is actually quite a complex physiological process, but many researchers and experts explained it as simply as possible.

When the body loses fat, the fat cell does not go anywhere or move into the muscle cell to be burned. The fat cell itself stays right where it was Mehabolism the skin in thighs, hips, arms, etc. Fat is stored inside the fat cell in the form of triaglycerol.

By lipolysis, each molecule of triaglycerol splits into glycerol and three fatty acids. The reaction catalyzed by hormone-sensitive lipase HSL. Not only because they have a faster metabolism than everyone else as the old adage goes, but also because of their calculated total calorie intake.

They slept 6—8 h a night, drank little or no soft drinks avoiding excessive sugar contentsrarely ate out processed foods are kept to a minimumate meals sitting down people who ate a meal standing up, ate twice as much after they finished metavolism the food, therefore they considered the food to be a snack, not a mealdo not really snack a lot and also built an eating and exercise routine into their lives meals were eaten at regular times during the day.

Too much and too little adipose tissue can cause severe health implications. More commonly, too much adipose tissue leads to obesity, mainly from too much visceral fat.

Obesity leads to a number of ajd health problems. It increases the risk of developing type 2 diabetes as it causes the body to become resistant to insulin. This resistance results in high levels of blood sugar which is bad for health.

Obesity also increases the metaboliem of developing high blood pressure, high cholesterol levels, and an increased tendency for blood to clot leading to risk of heart attacks and stroke Anderson et al. In eating disorders, such as anorexia nervosa, the patients do not eat enough food to maintain their adipose tissue levels.

This means that they can lose a dangerous amount of body weight Kershaw and Flier Insulin in those people may be high, yet it is not enough to normalize the level of glycemia Al-Goblan et al. In order to develop insulin resistance and obesity, thereby causing type 2 diabetes, β-cells should not be able to compensate fully for decreased insulin sensitivity.

Adipose tissue in control of metabolism

However, the molecular basis for how NPRC gene expression is regulated is still poorly understood. We used both a fat cell culture model and high-fat feeding in mice in combination with molecular biology approaches to investigate the transcriptional regulation of NPRC gene expression.

We identified a transcription factor called PPARγ, which stands for p eroxisome p roliferator- a ctivated r eceptor gamma, as a significant regulator of NPRC gene expression in mouse adipocytes, and established a new connection between PPARγ and the control of adipocyte NP signaling in obesity.

PPARγ is also the target of an anti-diabetes drug, as diabetes is a common metabolic consequence of obesity. For the next step, we will investigate the regulation of NPRC gene expression in physiological conditions such as in brown adipose tissue and during adaptive thermogenesis.

Brown fat also appears beneficial for consuming glucose and thus can reduce the risk of type 2 diabetes. This study suggests that interventions that reduce NPRC level or activity could be metabolically beneficial for the treatment of obesity.

This work was supported by funding from the National Institutes of Health and the American Diabetes Association. School of Medicine. The accumulation of fat helps keep you warm by literally providing insulation for your organs.

In humans, too much white fat can cause obesity. Too much white fat around the midsection may also create a higher risk of heart disease, diabetes, and other diseases.

BAT stores energy in a smaller space than white fat. When brown fat burns, it creates heat without shivering. This process is called thermogenesis. During this process, the brown fat also burns calories. Brown fat is highly regarded as a possible treatment for obesity and some metabolic syndromes.

Scientists used to believe that only babies had brown fat. They also thought this fat disappeared by the time most people reached adulthood.

Researchers now know that even adults have small reserves of brown fat. This recruitable type is found in muscles and white fat throughout your body.

Certain drugs can cause the browning of white fat. Thiazolidinediones TZDs , a type of drug used to help manage insulin resistance, can help with brown fat accumulation.

But TZD medications are prescribed to people diagnosed with diabetes and are not available to others. TZDs are also associated with weight gain, fluid retention, and other side effects. Exposing your body to cool and even cold temperatures may help recruit more brown fat cells.

Some research suggests that just 2 hours of exposure each day to temperatures around 66°F 19°C may be enough to turn recruitable fat brown. You may consider taking a cold shower or ice bath.

Turning the thermostat down a few degrees in your home or going outside in cold weather are other ways to cool your body and possibly create more brown fat.

Other research on mice suggests that a protein called irisin may help transform white fat to brown. Humans also produce this protein. One study found that people who were more sedentary produced less irisin than those who exercised more often. Specifically, levels are increased when people do more intense aerobic interval training.

Exercise is highly recommended by doctors for heart health and weight management. Current physical activity guidelines for adults include doing one of the following every week:. But exercise still has many health benefits. More research is needed on humans. Researchers are still trying to understand the genes that control how white and brown fat develops.

In one study , scientists engineered mice to be born with very little brown fat by limiting a protein called Type 1A BMP-receptor. When exposed to cold, the mice created brown fat from their white fat and muscles anyway, showing the power of recruitment.

Abstract Background Adipose tissue is a type of connective tissue composed of adipocytes. 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.

The two kinds of adipose tissue in mammals. Full size image. Distribution of adipose tissue Everyone does not carry their adipose tissue in the same anatomical locations. Factors that determine fat distribution A primary factor is genetic background, which can be seen by looking at the similarity in fat distribution within same-sex family members.

Risks of fat accumulation 1. The process of fat deposition Lipogenesis is the process of fat deposition that occurs in the liver and adipose tissue Kersten Should we try to increase our brown fat content?

White adipose tissue as an endocrine and secretory organ Adipose tissue is now known to be a very important and active endocrine organ Coelho et al. Adipose tissue as an endocrine and secretory organ. What happens when fat cell is burned?

FAT MOBILIZATION

The cells are stained with Oil Red O, which highlights lipid or fat droplets that accumulate with the fat cells. The metabolic studies described here indicated that fat cells produce these fatty acids, in part, from essential amino acids rather than sugar only. In the new study, researchers discovered that as fat cells develop, they change what types of nutrients they metabolize to produce fat and energy.

Pre-adipocytes, which are precursors to fat cells, preferentially consume glucose, a simple sugar, to grow and make energy.

But when pre-adipocytes become fat cells, researchers found that they metabolize not just glucose, but also branched-chain amino acids, a small set of the essential amino acids for humans.

student at UC San Diego and first author of the study. Metallo and his team studied the metabolism of fat cells from the pre-adipocyte stage throughout the fat cell differentiation process. They induced pre-adipocytes to differentiate into fat cells and cultured the cells in media containing nutrients enriched with carbon isotopes, a form of carbon atoms that are used as metabolic tracers in cells, animals, and people.

Through this method, researchers were able to trace what carbon-based nutrients the cells metabolized and what they produced at different stages of the cell differentiation process.

This means that they can lose a dangerous amount of body weight Kershaw and Flier Insulin in those people may be high, yet it is not enough to normalize the level of glycemia Al-Goblan et al.

In order to develop insulin resistance and obesity, thereby causing type 2 diabetes, β-cells should not be able to compensate fully for decreased insulin sensitivity.

The non-esterified fatty acids NEFAs that are secreted from the adipose tissue in obese people may lead to the hypothesis that insulin resistance and β-cell dysfunction are most likely linked Kahn et al.

When we talk about fat loss, much of the information available can be confusing. Commonly, too many calories are mistakenly cut to really low levels to accelerate fat loss, almost certain to leave the plateau where further fat loss is difficult.

Rapid caloric reduction will cause a decrease in muscle mass and slow basal metabolism. The body should be stimulated by certain fat burner to liberate fat, without fat cells resisting are being broken down as fuel Paul These supplements contain a number of ingredients, each with its own proposed mechanism of action Podder et al.

A good fat burner must burn the stored fats for energy, break down and mobilize the fat cells, and increase the metabolic rate to burn stored fats and inhibit fat cells from enlarging Nawrot et al.

The list of supplements that claimed to increase or improve fat metabolism is long. The most popular supplements include caffeine, carnitine, green tea, conjugated linoleic acid, and chromium Westerterp-Plantenga et al.

In this review, the evidence for some of these supplements is briefly summarized. Based on the available literature, caffeine and green tea have data to back up its fat metabolism-enhancing properties.

For many other supplements, although some show some promise, evidence is lacking. The list of supplements is industry-driven and is likely to grow at a rate that is not matched by a similar increase in scientific underpinning.

Caffeine is found in coffee, tea, soft drinks, cocoa, and cola nut. It has been most widely used in fat-loss products Greer et al. Caffeine is not only an energy enhancer but it is also becoming a popular fat loss supplement and workout performance booster Schwenk et al.

Many published studies are documenting its effectiveness at weight loss and reducing body fat Acheson et al. These studies have shown that caffeine is capable of increasing the release of stored fat, as well as the rate at which calories are burned.

The effects of caffeine are best realized when used in combination with other supplements. Caffeine promotes fat loss at two major sites: fat cells and muscle cells.

The action of caffeine at the fat cell appears to be supportive of the fat loss signal generated by neurotransmitters and drugs that stimulate β-adrenergic receptors Klein et al.

These receptors are stimulated by adrenalin and similar chemicals. At rest and without the addition of caffeine, there is not much fat release or increase in calorie burning because of the effect of a competing class of adrenergic receptors, A2-adrenergic receptors Belza et al. While β-receptors promote fat loss and increase calorie burning, the A2-receptors do the opposite Hursel et al.

Green tea extract contains catechin epigallocatechingallate EGCG , the active ingredient Cabrera et al.

It was discovered that EGCG inhibits catechol-O-methyltransferase, an enzyme that breaks down norepinephrine. The higher levels of norepinephrine in the body enhance the overall rate of fat loss by stimulating the release of fatty acids from fat cells into the bloodstream for burning as fuel Johnson et al.

Researchers examined the effects of green tea on weight loss in obese men and women. Participants followed a diet plan with green tea or a placebo for 12 weeks.

Energy expenditure and fat oxidation, or fat burning, were measured at the beginning of the study and during weeks 4, 8, and Scientists observed that the green tea group lost more body fat compared to the placebo group Hofman et al. Protein supplementation is used by athletes to promote positive nitrogen balance throughout the day without dramatically increasing caloric intake Demling Specifically, it is reported that whey protein may help build muscles, increase strength, control appetite, aid in weight loss, improve endurance, and boost energy levels Boirie et al.

Casein is a protein derived from milk products. It is used primarily by athletes to increase muscle mass and strength, control appetite, aid in weight loss, improve endurance, and boost energy levels.

It provides all of the amino acids necessary for growth Delbeke et al. Supplementation with 7-Keto may help increase the metabolic rate, accelerate weight loss, and help burn fat Bobyleva et al. These enzyme activations drive energy-producing substrates in a direction of less efficient ATP production relative to heat production.

The enzymes also promote the utilization of fat stores for energy and heat production Haller et al. Yohimbe comes from the bark of a particular African tree. It may be burn off stubborn body fat Rao et al. Yohimbe is most often promoted in dietary supplements as effective in increasing muscle mass by boosting testosterone levels, accelerating weight loss, and increasing energy levels Zahorska et al.

It is famous by enhancing blood flow and makes the oxidation of fatty acids easier Gades et al. Yohimbine acts on the adrenergic receptor system of fat cells, which regulate thermogenesis.

The beta-subunits of the adrenergic receptors targets of ephedrine can be seen as stimulatory for fat loss as they increase the activity of the enzyme adenyl cyclase and subsequently cAMP levels Manore The alpha-subunits are more suppressive of fat metabolism, in which their activation reduces activity of adenyl cyclase and reduces cAMP levels specifically alpha-2 Carmen and Víctor Yohimbine is a selective alpha-2 adrenergic receptor antagonist as it has a fold higher affinity for the alpha-2 subunit than it does for the alpha-1 subunit, which inhibits activation of the suppressive set of receptors and preserves adenyl cyclase activity and the effects mediated via the beta receptors Lalchandani et al.

Yohimbine itself can potentially induce fat loss indirectly via the release of adrenaline which is an activator of beta-adrenergic receptors MacDonald et al.

Increases in plasma free fatty acids and the density of alpha-2 adrenergic receptors remain similar at both time points, suggesting that yohimbine selectively loses the spike in adrenaline but not direct receptor fat burning effects Reiner et al.

Chitosan is a non-digestible fiber extracted from the shells of crabs, lobsters, and other crustaceans. It is prepared in supplement form for products as Chitosan-C and Chitorich Galitzky et al. It is an effective fat binder; it enters the body, binds to the fat in the food, and keeps it from being absorbed by the body Zenk et al.

There are two downsides to this method. First, fat blockers can prevent the body from absorbing nutrients it needs. Second, this bound fat still needs to leave the body, which it often does in the form of stomach pain, unpleasant anal leakage, and diarrhea.

Chitosan is recommended for reducing lowering cholesterol levels and promoting weight loss Pooyandjoo et al. L-Carnitine is a catalyst synthesized from amino acids and required for the transport of fatty acids from the bloodstream into the mitochondria during fats breakdown to generate metabolic energy for maintaining a healthy body weight.

It is widely available as a nutritional supplement Anton et al. Chromium is a trace element, which can increase insulin efficiency.

It reduces insulin resistance, and glucose is diverted towards muscle rather than into fat storage Tian et al. It builds muscle at the expense of body fat gains Fomous et al. Chromium supplementation led to reduced cravings for fat, not carbohydrates Shekelle et al. Ephedrine is a sympathomimetic amine, derived from various plants in the genus Ephedra , commonly used as a powerful stimulant, weight loss supplement, and appetite suppressant Clapham and Arch Synephrine is an alkaloid, derived primarily from the immature fruit of Citrus aurantium , and is commonly used in weight loss.

It has gained significant popularity as an alternative to ephedrine but it is safer and effective than ephedrine Bredsdorff et al. Raspberry ketone is a natural phenolic compound of red raspberries, cranberries, and blackberries Cotten et al.

However, no effects on body weight of rats were observed with doses up to times greater than the estimated intake in humans Ivy The high-dose effect is reported to stem from the alteration of lipid metabolism, increasing norepinephrine-induced lipolysis Onakpoya et al.

Pyruvate is the salt of pyruvic acid, found in most dietary supplements combined with a mineral such as calcium or magnesium to improve stability Whingham et al. It found to enhance weight loss, decrease appetite and fatigue, as well as increase energy levels, exercise endurance, and muscle glycogen stores Onakpoya et al.

Conjugated Linoleic Acid CLA has been found by researchers to encourage fat breakdown Millan et al. CLA transports dietary fat into cells to be burned for energy or used to build muscle Brenot et al.

Suppressants that take away general hunger are called noradrenergic drugs Gray et al. The other class of suppressants works by manipulating serotonin reuptake to prevent a sense of the need to eat more Whelan et al.

For example, Hoodia gordonii , a plant in the South African desert, was originally used by hunters to ward off hunger and regulate thirst on long hunting expeditions. This splendid plant can help to bide the time between meals Madgula et al.

A purified extract of Hoodia , known as P57, was injected in an in vivo study directly into the brains of rats and easily broken down by the liver Spadafranca et al.

However, an in vitro study was found that P57 was generally not inhibited metabolically by human liver enzymes and has a relatively high secretion rate Fu et al. Carb Blockers are composed of the extract of Phaseolus vulgaris , the botanical name for kidney bean and often mixed with other ingredients such as chromium, vanadium, and fenugreek Kelly et al.

They are preventing the enzyme alpha-amylase which is produced in saliva from binding with starches and break down the carbohydrates into molecules that the body will absorb Mussolino et al. Thyroid regulators, such as guggul extract, are an ingredient which is found to improve thyroid functioning to produce more thyroid hormones and increase fat metabolism.

These supplements may keep the basal metabolic rate BMR at higher levels to burn and lose more weight Wilson et al. Some authorities claim that these supplements can safely be used in small amounts and they can be effective at jump-starting weight loss.

Side effects are expected and ranged from uncomfortable to fatal Smith Anyone with any sort of pre-existing heart, hormonal, or digestive condition should seriously consider avoiding fat burning supplements. For other people, it remains a personal choice, but one that should be made with a certain degree of wariness Berdanier et al.

Most fat burner supplements often contain questionable ingredients and increase risk for an array of serious consequences, including heart palpitations, seizures, psychosis, severe anxiety, distress, and mood swings Wardlaw et al.

There are three macro-nutrients that can be present in food: fat, protein, and carbohydrate. One gram of protein yields 4 calories, 1 g of carbohydrate yields 4 calories, and 1 g of fat yields 9 calories. So basically, fats can provide double calories to the body compared to the other two nutrient units, but this does not mean that fats are bad, they are not Montama et al.

Many healthy fats are essential for the harmonious functioning of the body and foods that provide these fats need to be an integral part of the diet Schmitt et al. The body also needs to expend energy in order to digest foods to get energy from them, so a small percentage of old fuel is burnt off in the process of acquiring new fuel.

The harder the food is to digest the more energy is expended to digest it Jeukendrup et al. Fat is an important nutrient for health and plays many different roles in the body. It supplies the body with energy, helps the body absorb vitamins A, D, E, and K, and helps the body grow and develop Vanhala et al.

They found to lower cholesterol levels and reduce the risk of heart disease. They are divided into monounsaturated fat, which can be found in avocados, nuts, and vegetable oils Hooper et al. They are found in beef and veal meat, chicken meat, and dairy products Kim et al.

They are made from a chemical process known as partial hydrogenation; this is when liquid oil is made into solid fat. Trans fats have been shown to raise bad cholesterol LDL levels and lower good cholesterol HDL , increasing the risks for heart disease Prentice They are found in hard margarines, shortening, cakes, cookies, crackers, croissants, doughnuts, muffins, pastries, and other snack foods Carlsen et al.

Although fat contains more calories than protein or carbohydrates, the secret is in what fats actually do when they enter the body that makes the difference.

Saturated and trans fats, especially when combined with high carbs will pile on the pounds. Controlling carbs allow the body to return to its natural ability to burn fat. As long as the carbs intake is controlled, the calories from fat are immediately used for energy which means they would not be stored.

The second step, involves the consumed fats within the body to generate energy. Trans fats, found in pre-packaged foods and baked goods, and anything deep fried should be avoided.

Anything with hydrogenated or partially hydrogenated vegetable oil is a pound packer Vanhala et al. Good fats help in burning body fat, not to feel hungry, enhance metabolism, and stimulate certain hormones that have many functions within the body. There are certain foods that are better than others for fat burning: Avocados, is rich in oleic acid and beta-sitosterol monounsaturated fats , it helps in fat burning and lowers LDL cholesterol and triglycerides Schneider et al.

Nuts cashews, pecans, almonds, walnuts, peanuts Harris ; Parra et al. Omega-3 fats help burn fat by enhancing the body response to leptin that signals the brain to suppress appetite and eat less for maintaining weight loss.

Leptin stimulation reduces the activity of neuropeptide Y, a neurotransmitter that can trigger the hunger reflex Holm and this in turn increase the metabolism by enhancing the thyroid output King Palm oil, coconut oil, and cow butter contain medium chain triglycerides MCTs , saturated fats, with an unusual chemical structure that can be digested easily.

They contain fewer calories than other fats and they are absorbed and used directly for energy. Foods rich in MCTs suppress the appetite and help lose body fat Naber et al. All literatures, articles, and newsletters refer that the five mechanisms of how proteins burn fats were achieved by consuming protein-rich meals, which stimulate glucagon and growth hormone release and rich also in nitrogen, boost metabolism, suppress appetite, and get us to feel full Karst et al.

We wrote in the next section some examples of these proteins. The following mechanisms are through which protein may assist the body in burning fat more effectively. By keeping insulin production low, the body can access and utilize fat as a fuel source more effectively.

Glucagon stimulates the liver breakdown of glycogen to glucose and stimulates the gluconeogenesis in the liver by increasing the uptake of amino acids.

Protein stimulates growth hormone GH release from the anterior pituitary. GH may indirectly promote fat loss. It acts directly on the fat cells and stimulates the release of fatty acids and glycerol into the blood stream. A particular amino acid, glutamine, has been shown to dramatically boost growth hormone release in the body, which then may promote greater fat burning Guo et al.

Protein provides the building blocks of body tissues and regular consumption of it, i. 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.

As a result, the thermic effect of food TEF , which means the amount of energy expended through the process of digestion increases, which increases the overall amount of calories the body burns during the day Banni Protein has powerful appetite suppressing effects, especially compared to the other macronutrients.

Its appetite-suppressing qualities come from the fact that protein stimulates the release of cholecystokinin CCK from the stomach cells. This hormone then travels through the bloodstream to the hypothalamus in the brain where it tells the brain that the stomach is full Whingham et al.

From the aforementioned 5 mechanisms, it is easy to conclude why protein can help promote fat burning in the body. It can help in fat burning by simply making an effort to add a small portion of protein, from a variety of protein sources to each meal.

Protein, foliate, and vitamin D are found in red meat beef, veal, pork , skinless turkey, and chicken. Proteins are not only more complex to digest and assimilate but they also require more energy to be stored as fats, so, they help to feel full and help the body in fat loss Coyle and Patrick Dairy products provide whey protein and casein that build muscle, control appetite, and aid in weight loss Boirie et al.

They contain CLA that works to lower the triglycerides and cholesterol leading to upregulate the body metabolism Leonard ; Kim et al. The process of converting dairy down into lactic acid causes the body to utilize the energy stored in fat.

Low-fat dairy products such as cheese, milk, and yogurt contain calcium and complex carbohydrates which work to kick metabolism into action and burn fat Villarroel et al.

Peanut butter provides protein, vitamins B 3 and E, magnesium, cortisol, foliate, dietary fiber, and arginine all of which increase protein synthesis, boost metabolism, and help in fat burning Christensen et al.

Eggs are rich in satiating protein. Eggs for breakfast can boost weight loss plan more than a carbohydrate-rich breakfast Soerensen et al.

Several studies have correlated higher calcium intakes with lower body weight or less weight gain over time Parikh et al. Two explanations have been proposed. First, high-calcium intakes might reduce calcium concentrations in fat cells by decreasing the production of parathyroid hormone and the active form of vitamin D.

Decreased intracellular calcium concentrations, in turn, might increase fat breakdown and discourage fat accumulation in these cells Earthman et al.

Second, calcium from food or supplements might bind to small amounts of dietary fat in the digestive tract and prevent absorption of this fat Mallard et al. 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.

Nevertheless, the association between vitamin D and obesity raises the question of whether increasing vitamin D concentrations might reduce body weight Gittleman ; Young et al. Fruits, although all fruits are strong healthy food, the fact is that only some have fat-burning properties.

The best choices include citrus fruits; the low-glycemic fruits lemons, limes, oranges, tangerines, and grapefruits , grapes, cherries, and kiwi fruits. These fruits contain vitamin C, which not only works to dilute fat and cholesterol by its acidity but also helps release the fat cells.

Apples and berries, especially raspberries, are the most pectin-rich fruit which limits the ability to absorb fat. Another choice is peaches, pears, plums, strawberries, and pomegranates. They are rich in vitamins and minerals, high in water content, and have low glycemic index.

They found to improve body metabolism and reduce bad cholesterol Denker et al. Bananas and mangoes make for excellent snack foods as well as breakfast foods. Berries are extremely high in B vitamins that stimulate the thyroid hormone and boost metabolism.

It is advised to eat the fruits whole for added fiber and increased the feeling of fullness Gittleman Grapefruit has been an integral part of many diets. Its fat-burning mechanism is due to the high-fiber content that is known to burn more calories during the digestive process than calories in the grapefruit itself.

Grapefruit pills were found to improve insulin resistance compared to its juice Terry Vegetables have a low-calorie profile while containing essential minerals and vitamin that improve the metabolism of the body, except for certain calorie-rich vegetables like potatoes and sweet potatoes.

Potatoes were preferred to be cooked with the outer skin because it is a good source of insoluble fibers Li Veggies like broccoli, spinach, artichoke, peas, cauliflower, cabbage, and carrots are excellent sources of minerals and have low calories that offer fat burning.

They are rich in fiber, which delays hunger Biesiekierski Cucumbers are high in sulfur and silicone, both of which help the body rid itself of fat content. Beets are rich in iron, potassium, magnesium, and fiber.

They enrich the blood and aid in liver function, thus helping to rid the body of fat through elimination Whitehead et al. Onions and garlic also make great fat burners. The best way to cook veggies would be to boil them or stir fry them with healthy oils like olive oil, sunflower oil, Soybean oil or sesame oil Julkunen et al.

Grains and Seeds are rich in fibers which can control the blood sugar. Oats are rich in fiber, especially, insoluble β-glucan which is found in researches to stabilize the blood sugar of type II diabetics better than other types of fiber and improves metabolism Ramdath et al.

Oats also are digested slowly, keeping insulin production down. It is advised to eat one bowl of oatmeal at breakfast Mudryj et al.

They can balance copper and zinc which support thyroid function and boost metabolism Whiting et al. They are excellent sources of dietary fiber and are known to lower the bad cholesterol and thus contribute to heart health.

The best way to eat legumes would be to eat the whole grains Earthman et al. Not only is flax oil rich in omega-3 but it also is found to lower cholesterol van Avesaat et al. Thermogenic foods, are foods that help burn fat by heating up the body Pathak et al. Capsaicin, a well-known thermogenic compound found in chili peppers, jalapenos, and ginger, works to heat up the body, speed up metabolism, and burn fats Rhoades and Tanner It would not count as food because it has no calories.

Water helps improve the overall metabolism of the body and thus helps burn fat. And of course, water helps flush out toxins and thus improves the capacity of the body to stay healthy Gittleman Many studies have shown that extra water intake, especially up to ml at mealtime, was conducive to weight loss Stookey et al.

Certain foods are rich in their water content and thus help in the process of fat reduction and feeling full quickly, for example are watermelons, cantaloupes, cucumbers, snake gourd, papaya, and chard Rosenberg et al. The ingested and the environmental toxins that were taken every day can be stored in fat cells.

Toxins released during weight loss had the capacity to damage the fat-burning mitochondria and interfere with the thyroid hormones and their receptor sites, interfere with enzymes, and interfere with leptin signals to hunger reflex.

A number of studies have been found that a decreased metabolic rate is in response to the presence of toxins affecting the thyroid hormones and the rate at which the liver excretes them Hsueh et al.

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. In addition to limiting carbohydrates, it recommends eating fat-burning fats, high-fiber vegetables and fruit, clean protein, and thermogenic foods and supplements Gittleman Caloric intake on the fat flush plan ranges from to calories per day, which is in line with the nutrition recommendations for weight loss Klein and Kiat During this phase, margarine, sugar, oils except flaxseed oil , grains, bread, cereal, starchy vegetables, dairy products, and some spices are restricted.

During the second phase, calories are increased from to calories daily. It includes the same food that is in the first but with the addition of butternut, sweet potato, fresh or frozen peas, brown rice, and carrots once weekly.

This phase continues until reaching the needed weight. The last phase is to maintain weight loss and entail or more calories daily. Certain foods that were eliminated in phase 1 are reintroduced back such as some starchy carbohydrates, dairy, and gluten-free grains Gittleman It aims to cleanse the liver, improve wellness, and produce weight loss.

An expert opinion is that the elimination of all margarine, fats, oil, sugar, bread, grains, high-carbohydrate vegetables, and dairy products can be difficult for some people because they found the remaining food list so restrictive.

Fat flush plan is incompatible with vegetarian diet because of the importance of eating lean protein from animal sources, which they cannot do; so vegetarians face difficulty in following this diet. The plant-based protein could be a substitute animal-based protein for vegetarians.

Protein found in soybean and legumes is considered as an acceptable protein substitute on the Fat flush plan. The lacto-ovo vegetarians consume eggs, light yogurt, and light cheeses as a source of protein Picco We can turn our body into fat-burning machine by including low-calorie foods instead of high-calorie foods in our diet.

The fat burning supplements are not alone to burn fats alone. Without a proper diet and regular exercise, we cannot reach the needed goal. If we decide to start any fat flush dietary program, we should seek approval from the doctor prior to starting. To avoid toxins which delay the burning process, we should eat organic foods as much as we can, avoid processed foods, and use natural product to be away from chemicals, additives, or preservatives.

Too much fats increase the risk of diabetes with the alarming complications of cardiovascular disorders. Modification of an unhealthy diet, bad eating habits, and lifestyle factors should remain the cornerstone in managing body fats.

New kinds of natural foods should be added in daily meals to improve fat burning process to avoid health complications. Scientific efforts must certainly be more oriented to discover how we should try to increase our brown fat cells to help in fat burning.
