In this article, you will learn everything you need to know about the best fat burners on the market and how they work.
Fat burners are naturally occurring compounds that science shows promote weight loss.
While some literally do burn fat—the fat burner umbrella also includes ingredients that prevent weight gain or promote pound-shedding through other means.
Typically, these compounds fall into the following groups—although some fat burning ingredients cover more than one category:
- Thermogenics—increase the internal body temperature, which in turn elevates the metabolic rate, burning fat for energy.1
- Appetite suppressants—discouraging you from eating and therefore preventing the ingestion of unnecessary calories.cussin
- Hormone boosters—encouraging the body to produce hormones that elevate fat loss.
- Mood enhancers—creating a positive mindset meaning you’re less likely to comfort-eat.2
When more than one of these fat-burning ingredients are combined, you have a fat burner supplement. These products aim to address numerous aspects of weight loss, inducing the most effective way to shed pounds.

Fat burning ingredients
I’ve compiled below what I consider to be an exhaustive best fat burning ingredients 2020 list. Each one of these compounds has completed clinical testing for its shredding ability.
When selecting your weight loss supplements—always ensure they include a majority of these ingredients.
Green Tea Extract
This phenomenal green tea extract includes many features of the most excellent fat burners—making it, if you will, a super-burner.
Firstly, this compound includes caffeine and EGCG (epigallocatechin-3-gallate), which boosts the metabolic rate—burning more calories. Research from Laval University shows that when participants supplemented with these elements,
“Twenty-four-hour energy expenditure increased significantly by about 750 kJ with all EGCG-caffeine mixtures compared with placebo.” 3
Secondly, if you’re consuming green tea extract and partaking in weight training, a study from the University of Birmingham demonstrates that its fat-burning abilities are intensified:
“Green tea extract ingestion can increase fat oxidation during moderate-intensity exercise and can improve insulin sensitivity and glucose tolerance in healthy young men.” 4
Additionally, research on mice has shown that green tea extract can prevent new fat from being formed:
“Dietary supplementation of EGCG resulted in a dose-dependent attenuation of body fat accumulation. Food intake was not affected, but feces energy content was slightly increased by EGCG, indicating a reduced food digestibility and thus reduced long-term energy absorption…supportive of a decreased lipogenesis.” 5
For the ultimate in fat-busting returns, look to ingest more than 270 mg per day of green tea extract.6
While you need to fuel your muscle growth and your workouts through calories—taken to the extreme, excessive food consumption can lead to weight gain. Too much poundage can hide your gains—as the fat sits on top of your muscle.
Glucomannan, coming from the konjac plant, is a fiber. When you consume it, this ingredient swells in the stomach, promoting a feeling of satiety. Thus, making it one of the supreme fat burners for appetite suppression.
One study, from St Michael’s Hospital, Toronto, demonstrated that supplementing with Glucomannan resulted in subjects consuming 47 percent less food than those on a placebo.7
Additional research, published by Cambridge University, explained that consuming one gram of Glucomannan for 16-weeks had tremendous results on both appetite and overall health. They declared,
“A 16-week dietary supplement of soluble fiber in overweight or obese patients was well tolerated, induced satiety and had beneficial effects on some CVD risk factors, the most important of which was a significant decrease in plasma LDL-cholesterol concentrations.” 8
Hence, to witness results, you should consume at least one gram of Glucomannan every day.
The body produces a hormone known as leptin. This powerful compound sends signals to the brain telling you that you’re full and you don’t need to eat anymore.9
Under normal circumstances, leptin is released by the adipose (fat) tissue when they become saturated. However, caffeine is one of the best fat burners for “cheating” this process.
One study explains that:
“Caffeine…(is) able to restore the leptin signaling in neurons by overexpressing anorexigenic peptides…and/or repressing orexigenic peptides (neuropeptide Y/agouti-related peptide), thus decreasing food intake.” 10
Furthermore, caffeine increases mental ability and improves mood by boosting dopamine production, as explained by this research from the University of Lorraine:
“Caffeine activates noradrenaline neurons and seems to affect the local release of dopamine.” 11
This is important.
Feeling stressed or depressed promotes emotional-eating. The dopamine release caused by caffeine can alleviate this situation. 12
This is one ingredient where you need to be careful with the dosage. For best effects, 200 mg of caffeine daily is ideal. However, as some people have low tolerances to caffeine—if you witness any side effects—drop the quantity.
Caffeine truly is the best for fat burning.
People have used this ingredient in Ayurvedic medicine for centuries—where its roots were ground to make tea. However, today, scientists have extracted the active forskolin compound—making it one of the top fat burners.
In 2005, Scientists at the University of Kansas explained:
“Oral ingestion of Forskolin (250 mg of 10% forskolin extract twice a day) for 12 weeks was shown to favorably alter body composition while concurrently increasing bone mass and serum free testosterone levels in overweight and obese men. The results indicate that Forskolin is a possible therapeutic agent for the management and treatment of obesity.” 13
So, what’s the working process?
Consuming Forskolin elevates your cAMP (cyclic adenosine monophosphate) levels. This “messenger” encourages your body to produce lipase and cyclase.14
These two enzymes breakdown fatty acids—which are then used for energy-burning them as fuel and promoting weight loss.15
Furthermore, Forskolin boosts the production of T3 and T4 hormones—which prevent the onset of hypothyroidism which leads to weight gain.16 17
For significant pound-shedding—use a dose of 250 mg or above—as proven effective in the University of Kansas research.
The amino acid 5-HTP (5-hydroxytryptophan), elevates the production of serotonin, as explained in this clinical study:
“5-HTP is well absorbed from an oral dose, with about 70 percent ending up in the bloodstream. It easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin. In the CNS, serotonin levels have been implicated in the regulation of sleep, depression, anxiety, aggression, appetite.” 18
Hence, this makes it one of the effective fat burners, since it:
- Improves sleep—scientists have linked insufficient and interrupted sleep to obesity and weight gain.19
- Elevates mood—preventing excess calorie intake through inhibition of comfort-eating.
- Regulates the appetite.
Furthermore, scientists at the University of Queensland explained that:
“This study shows that…5-hydroxytryptophan…is adequately absorbed…and that the supplementation of the diet of overweight women with 5-hydroxytryptophan increases the feeling of satiety associated with a decrease in BMI.” 20
An effective dose of 5-HTP is around 100 mg or more daily.
One of the good fat burners for the dedicated bodybuilder.
Research from The Journal of Physiology states:
“Carnitine has a crucial role in lipid oxidation by mediating the translocation of long-chained fatty acids into mitochondria…supplementation resulted in reduced glycogen utilization, and is consistent with increased lipid oxidation.” 21
In short, instead of using glycogen stores for energy—carnitine burns fat. The more fat that’s burned, the higher your weight loss.
Additionally, experts explain that carnitine increases power, raises endurance and reduces recovery time.22
Green Coffee Bean
I would consider green coffee bean as the best fat burner for belly fat.
Let me explain.
Under normal circumstances, coffee beans are roasted to intensify their flavor. Which makes an excellent espresso—but destroys much of the nutritional value.
Green coffee beans are unadulterated—meaning that their fat-shedding powers aren’t lost.
Research from Japan explains that:
“It was found that 0.5 percent and 1 percent green bean coffee extract reduced visceral fat content and body weight.” 23
It’s not just the fact that this ingredient lowered weight—it’s the emphasis on the burning of visceral fat. This type of fat (also known as organ fat or intra-abdominal fat) is the enemy of bodybuilders.
It sits on our chests and stomach, covering the pecs and six-pack—hiding all your hard-earned gains.
The power behind green coffee bean lies in its chlorogenic acid content. This compound prevents fat accumulation, elevates fat-burning hormones and burns fat and glucose.24 25
To reveal your toned muscle—consume around 100 mg of this ingredient per day.
I consider cayenne not just one of the top fat burners—but also possibly the best thermogenic fat burner 2020.
Experts at the University of Maastricht examined the power of cayenne pepper, mainly concentrating on its capsaicin content. They explain:
“Tools for obesity management, including consumption of capsaicin…have been proposed as strategies for weight loss and weight maintenance, as they…increase energy expenditure (4-5 percent), fat oxidation (10-16 percent) and have been proposed to counteract the decrease in metabolic rate that is present during weight loss. Daily increases in thermogenesis of approximately 300-400 kJ can eventually lead to substantial weight loss.” 26
Additionally, a study in 2015 concluded that capsaicin inhibited the appetite:
“Capsaicin-treated subjects reported less desire to consume fatty foods, sweet foods, salty foods, and food overall, and achieved greater satiety after meals.” 27
To achieve the thermogenic and hunger preventing effects of cayenne pepper, consume 100 mg daily.
Also known as bitter orange, citrus Aurantium, is one of the most excellent fat burners known—as powerful as the now discouraged Ephedrine.
Ephedrine used to be the go-to weight loss product—a stimulant which promoted weight loss through thermogenesis.28
However, little knowledge of its long-term dangers—combined with the known side effects of heart palpitations, gastrointestinal complications, and psychiatric disorders led to it falling out of fashion.
In 2002, scientists from Georgetown University Medical Center explained that:
“Ephedrine has proven time and time again that it is an effective weight loss agent through its ability to increase thermogenesis and quench appetite. However, the publicity concerning adverse reactions has led to its gradual withdrawal from use…Citrus aurantium may be the best thermogenic substitute for ephedra.” 29
Experts believe it is the synephrine content that promotes hunger suppressing and fat-burning benefits. I recommend a 10-20 mg serving daily.
“Do Fat Burners Work?”
Yes. However, ensure you do some research.
Science has proven that numerous natural compounds can burn fat, prevent lipid accumulation, and inhibit the appetite. Only use supplements that contain the best ingredients, as illustrated in this article.
“How Long Does It Take for a Fat Burner to Work?”
It depends on the ingredients. Those which contain appetite suppressants have the most immediate effect—with users seeing a reduction in hunger within the first week.
For thermogenic and fat inhibitor compounds—the first results are witnessed after about a month—although the most profound losses are seen after 12 weeks of continuous use.
“What Is the Name of Illegal Fat Burners?”
The most common illegal fat burners (usually because they’re the most damaging to health), are:
“Do Fat Burners Come With Side Effects?”
The top fat burners are 100 percent natural ingredients, which are unlikely to cause any adverse health issues.
However, many fat burner supplements include stimulant caffeine—which can promote side effects such as agitation, headaches, and stomach upsets.
“What Is the Best Appetite Suppressant?”
The best hunger-preventing compound is probably the fiber glucomannan.
Hence, look for supplements that contain this ingredient—such as ShredFierce for men and Leanbean for women.
“How Do I Know If a Fat Burner Is a Scam?”
Signs that a fat burner supplement is a scam include:
- Ingredients are not individually quantified.
- The supplement includes a proprietary blend.
- None of the compounds are proven by science to reduce fat—check this article for the best ingredients.
- The company doesn’t offer a money-back guarantee.
- User testimonials are either absent, harmful or appear fake.
- The product makes ridiculous claims—or calls itself a “magic” pill or similar.
“Is protein important for losing weight?”
Yes, protein is essential, but that doesn’t mean you need protein powder in your diet.
Protein is crucial to maintain and rebuild muscle mass after exercise. It is especially important when you are dieting and eating fewer calories than usual. Protein-rich foods such as chicken, meat, fish, nuts, eggs, and beans are right to eat on a cutting diet to prevent muscle loss.
“Will Fat Burners Work Without Diet and Exercise?”
No, a healthy diet and exercise are vital—and if any fat burner supplement makes this claim—it’s untruthful.
You cannot take some lose weight tablets without putting in any work.
Nutrition, a healthy diet, eating enough protein, sleep is more important to burn more fat than using a weight loss supplement.
Fat burners vastly accelerate the process to burn more fat. However, you still need to exercise and watch the diet to lose weight.
“How Much Does a Fat Burner Help With Weight Loss?”
Fat burner supplements are invaluable tools when trying to lose weight.
The best examples target crucial areas such as preventing fat accumulation, inhibiting the appetite, and burning body fat through thermogenesis.
While you can shed pounds through diet and exercise alone—fat burners speed up your progress to lose weight.
“Do you need to count calories to lose weight?”
Many people like the approach to counting calories to lose weight, but is it a must to lose weight? No.
Many healthy and productive weight-loss diets do not require you to count calories.
The keto diet and many low carb diets do not require you to count calories.
They work by limiting the carbohydrate intake in your nutrition because too much carbohydrate consumption is often the reason people get fat in the first place.
“What is the most simple weight loss diet?”
The most simple weight loss diet does not require you to count calories.
It works that way that you cannot eat any carbohydrates expect after workouts.
So you can eat carbs after working out but not any other time.
Eat protein-rich foods (chicken, fish, steak, eggs, etc.), green leafy vegetables in your other meals, and remember to drink a lot of water.
This diet should work very fast, and you don’t need to pay attention to calories consumed.
“What is a thermogenic?”
A thermogenic is a fat burner that increases the internal temperature in the body, which increases metabolism. It is often referred to as these ingredients as a thermogenic, and they are beneficial to increase fat loss.
“How do you increase metabolism?”
The most effective way to boost metabolism is to exercise and lift weights. Keep protein-rich foods in your diet, drink cold water, and sleep well.
You can also use some fat burners that naturally increase your metabolism.
“Do You Need a Fat Burner to Lose Belly Fat?”
Science has shown that one of the most effective fat burners for belly fat is green coffee bean extract. Numerous studies demonstrate it can directly target abdominal weight even though I have a hard time believing that it works like that. The most effective way to lose belly fat is to aim to lose weight. At some point, your body will start to burn more fat in your belly area. You cannot spot reduce fat; you have to watch your diet, nutrition and exercise regularly to speed up metabolism.
“Is MCT Good for weight loss?”
MCT can increase the release of hormones that make you feel full, which is very good to decrease consumed calories. It is a healthy way to burn more fat, and you can add MCT into your healthy diet.
“What Foods Help Burn Fat?”
Fat burners in food form are:
- Cayenne pepper.
- Grape Fruit.40
- Green tea. 42
- Garlic. 43
- MCT Oil
“How to Take the Fat Burners”
Fat burners are oral supplements. As such, they’re taken daily with water and require no needles.
Each burner or supplement will have its directions for use and serving size. Follow the manufacturer’s instructions since many may contain stimulants such as caffeine—which could promote unwanted effects if taken to excess.
