Best Fat Burner Supplements to Lose Weight (Compare Top 2022 Products)

Fat burners have been a hot topic of discussion. Most fat-burning supplements are touted for their supposed ability to boost the metabolism, suppress appetite, and help burn fat for energy production purposes. Since then, natural fat-burning supplements have surfaced at faster rates, giving the scientific community something to stand in support of (at least to a certain degree).

The big question now becomes, “How does one go about choosing the right fat burner?” After investing a lot of time, our editorial team narrowed down the best fat burners of 2021.

Every conceivable perspective into its uses has been accounted for, and interested in finding out how your fat-burning needs can finally be fulfilled. This guide intends to provide relief and access to an endless array of fat burners.

The Best Fat Burners of 2021

As hinted earlier, choosing fat-burning supplements is no small feat, as individuals need to reflect upon the makers, science, clinical doses, and ingredients, among others. Before scavenging the internet for everything it may hold, we developed the ultimate ranking criteria that facilitated discarding possibly ineffective solutions and replacing them with potent kinds.

Before providing an overview of our process, we believe that introducing the best fat burners is the priority. Therefore, without any further delay, here they are:

Lean Belly 3X

image13

Company/Creator: Beyond 40

Starting Price: $59

Lean Belly 3X is touted as an advanced fat-burning supplement that eases inflammation, controls blood sugar, promotes healthy arteries, and maximizes fat cells metabolism. Regarding the brand itself, Beyond 40 is an endeavor that flourished because of a husband-wife duo who wanted to help transform the lives of men and women beyond 40 years of age.

In particular, Shaun and Karen Hadsall explicitly noted that they wish “to help you achieve your best possible health so you can enjoy your best possible life.” Having discovered a passion for fitness and nutrition at different points in life, the two – who are in their 60s and living healthily – decided to share their secrets to wellness.

Formulation Capsules
Dosage 2 capsules a day.
Money-back guarantee 60-day money-back guarantee.
Ingredients Safflower seed oil, BioPerine black pepper, Glycerine.
Price $59
Side effects Free from side effects.

BioFit

image1

Company/Creator: Chrissie Miller

Starting Price: $69

BioFit is a probiotic fat-burning supplement designed to populate the gut for weight loss and maximum immunity. While the idea of ingesting probiotics has recently gotten a lot of attention, only certain strains appear to have some effect, which means that individuals need to be extra careful with exercise and diets.

What initially drew us to this fat burner supplement was the ongoing efforts in educating consumers. Each BioFit purchase appears to include bonus guides, i.e., “The Truth About Dieting” and “Favorite Recipes,” and access to a private members area.

It’s a shame that their efforts are likely to induce doubt, as Chrissie Miller is dubbed the founder, but neither she nor the manufacturers can be verified. We did our research to see whether Chrissie is or worked alongside medical doctors or nutritional specialists, only to find nothing.

Ultimately, would we recommend BioFit? It is too soon to tell, but it looks like the fat burner supplement remains a favorite on the internet!

Formulation Capsule
Dosage 1 capsule daily
Money-back guarantee 180-day money-back guarantee.
Ingredients Bacillus subtilis (DE111), Lactobacillus rhamnosus, Lactobacillus casei, Lactobacillus Plantarum, Lactobacillus acidophilus, Bifidobacterium longum, Bifidobacterium breve
Price $69
Side effects Free from side effects.

Exipure

image8

Company/Creator: Jack Barrett, Dr. James Wilkins, and Dr. Lam

Starting Price: $59

Exipure is a healthy weight loss support supplement that targets burning fat in a whole new approach. Known as a fat burner supplement, the Exipure fat burner ingredients are truly rare and unique as nothing has ever been formulated like it before. Based on bleeding edge clinical data, the Exipure ingredients are scientifically proven to target one of the primary causes of unexplained weight gain, low brown adipose tissue levels.

Known as BAT, or brown fat, has been linked to all kinds of breakthroughs regarding its link to weight gain in adults.

Formulation Capsules
Dosage 2 capsules daily
Money-back guarantee 180-day money-back guarantee
Ingredients Kudzu, Perilla, Holy Basil, White Korean ginseng, Oleuropein, Quercetin.
Price $39
Side effects Free from side effects.

Biotox Gold

image2

Company/Creator: Biotox Nutrition

Starting Price: $79

Biotox Gold appears to have heads turning because it is unlike most fat burners introduced in this guide. Specifically, it is a liquid tincture that supposedly encompasses 20 plant-based nutrients that enhance detoxification. As maintained on the official sales page, one bottle suffices to induce a weight loss of 50lbs.

Presently, we neither know anything about Biotox Nutrition’s makers nor is a supplement’s fact available. Why is this solution popular? We have yet to find out, but collectively, our editorial team was not excited about it.

For instance, the claim that individuals can lose up to 50lb on Biotox Gold is nonsensical because healthy weight loss only implies a drop of anywhere between 1 to 2lbs weekly, or equivalently, 4 to 8lbs monthly. Likewise, seeing that the team at Biotox Nutrition isn’t standing proudly next to an alleged strong player in the market is too much of a red flag for us even to consider it.

We included this fat burner supplement in our list to show everyone that solutions in popular demand aren’t all that they are made out to be. Ultimately, we strongly advise consumers to thoroughly investigate the claims made by Biotox Nutrition, as known facts hint at deception.

Formulation Liquid
Dosage 10 drops daily.
Money-back guarantee 60-day money-back guarantee.
Ingredients Malabar tamarind, Panax ginseng, Guarana, Grape seed extract, Capsicum extract, Maca root, Green Tea extract.
Price $79
Side effects Free from side effects.

Burn Lab Pro

image3

Opti-Nutra Ltd. is a brand that has been recognized for developing fat burner supplements, selecting ingredients, and manufacturing everything with care. Out of all the thermogenic fat burner brands in this guide, this team demonstrates the significance of optimizing our biological functions in the cleanest possible manner while equally shining the spotlight on nutritional requirements.

If anyone wants their fats torched, muscles kept, and desire enhanced strength, Burn Lab Pro is deemed the way to go. Interestingly enough, team USA powerlifter Natalie Johnson uses this thermogenic fat burner to meet the physical demands of cutting weight in high-energy sport. She said, “I noticed my recovery getting better and energy levels were higher.

Formulation Capsule
Dosage 2 capsules daily
Money-back guarantee 90-day money-back guarantee.
Ingredients Forslean, Capsimax, Black pepper extract, Chromium.
Price $59
Side effects Free from side effects.

cAMP Boost

image4

The Nutraville team insists that after our 20s, the metabolism decreases by a rate of 10% every decade. Furthermore, by the time we reach our 30s, muscle mass might drop by 3 to 8% every decade. What does this have to do with anything?

Well, believe it or not, it is everything, as consumers might be left to suffer from weight gain, fatigue, stress, and high blood sugar levels, to name the least. To ensure that consumers have full support in upkeeping their health, the team devised a science-baked quiz to help pinpoint the exact Nutraville solution to try. One such solution might be their fat burner called cAMP Boost.

The team describes cAMP Boost as “the ultimate supplement for your weight loss needs,” adding that it is a great inclusion that helps meet a healthier and leaner body.

Formulation Capsules
Dosage 2 capsules daily
Money-back guarantee 365-day money-back guarantee.
Ingredients Sinetrol, Guarana seed, Grapefruit extract, Bioperine.
Price $67
Side effects Free from side effects.

CarboFix

image5

CarboFix is advertised as the best fat burner supplement designed to fight off belly fat, uncontrollable weight gain, and random hunger cries and cravings. By combining six key ingredients, this stimulant-free fat burner is trusted to activate AMPk. In so doing, individuals can supposedly “indulge in favorite carbs guilt-free.”

This weight loss supplement comes with incredible benefits in terms of burning fat without diet and exercise. That’s what makes this natural fat burner the best belly fat burner.

As we searched for more information on the makers, Gold Vida, we discovered that it is a Canadian-based company, but unfortunately, we’ve hit a dead end. People who have been advised to lay off carbohydrates for weight loss purposes might find comfort in CarboFix.

Formulation Capsules
Dosage 2 capsules a day
Money-back guarantee 60-day money-back guarantee.
Ingredients Berberine, Naringin, Chromium, Alpha-lipoic acid, Cinnamon bark.
Price $49
Side effects Free from side effects.

SuperHD Fat Burner

image21

SuperHD is the top thermogenic fat burner for men trusted to ramp up weight loss results. It embodies the coming together of a crucial antioxidant and other weight loss properties clinically proven to promote explosive energy, mental focus, a toned physique, and desirable fat burning.

As explained by the Cellucor team, “SuperHD has a multi-dimensional formula with ingredients to help you look and feel your best,” stressing that it’s all about establishing a healthy mind-body connection.

The ingredient of the best belly fat burner list seems like caffeine will have the most significant impact, as the proprietary blend is quite saturated and reflects a relatively low dose. Is this a good thing? Most probably not.

Formulation Capsule
Dosage 2 capsules a day
Money-back guarantee 30-day money-back guarantee.
Ingredients Caffeine, Green tea extract, Fruit extract, N-Acetyl-L-Tyrosine, Amla (Emblica Officinalis) fruit extract, Dandelion (Taraxacum officinale) root extract, Yohimbe (Pausinystalia Yohimbe) bark extract.
Price $29
Side effects Free from side effects.

CircadiYin

image6

CircadiYin is a belly fat burner supplement that promotes sleep to lose weight and stubborn body fat. The unnamed makers affirm that the included fat-burning ingredients can go as far as resetting our circadian rhythm so that metabolic function can be rectified.

Their claims on prioritizing sleep have been fulfilled through this weight loss pill. Additionally, the makers emphasize education through a series of free guides that ensure consumers take the proper steps towards weight management goals (i.e., lifestyle choices, exercise, dieting, detoxifying, etc.).

Individuals should bear in mind that the second result might be a metabolic boost. Whether this formula is solid enough to elicit wanted fat burning is a concern that needs to be brought up with customer service and details on the makers.

This weight loss supplement beats other weight loss supplements and fat burner supplements in terms of reducing fat.

Formulation Capsules
Dosage 1 capsule daily.
Money-back guarantee 30-day money-back guarantee.
Ingredients Melatonin, L-Tryptophan, Chamomile, Magnesium, Valerian, Goji berry.
Price $69

Instant Knockout Cut

image10

With emphasis placed on scientific evidence and reliability, Instant Knockout Cut is the best fat burner that promotes lean muscle mass, weight loss, thermogenesis, and curbing appetite.

The team at Roar Ambition is convinced that their solutions are fundamental for any cutting-related goals because they rely on “high-class facilities in the USA and UK and shipped from there too,” not to forget that their selection for of suppliers understand their mission and assist in “crea[ting] high-end supplements.”

Hunter Burn

image9

We meet Roar Ambition Ltd. yet again, but this time for a thermogenic fat burner called Hunter Burn. Hunter Burn is scientifically designed to “trim the waistline, keep muscle, boost confidence and make you feel unstoppable.”

At first glance, individuals are likely to gather that the team took a “simple is sweet” approach, as only a handful of ingredients qualified to eliminate hunger, to promote utmost wellness, and the more obvious one, fat burning.

Formulation Capsules
Dosage 6 capsules a day
Money-back guarantee 90-day money-back guarantee.
Ingredients Vitamin D3, Konjac root extract, L-theanine, Cayenne Pepper, Matcha green tea.

Java Burn

image11

Java Burn is a 100% natural stimulant-free fat burner intended to boost metabolism. Conceptualized and executed by fitness author John Barban, this supplement is reckoned to set fat storage on fire while curbing the appetite, enhancing energy production, and ensuring that individuals end their day with a caloric deficit.

Very few fat burner supplements can make your body burn fat as this weight loss supplement does.

On the topic of the maker, we trust that his expertise has been reflected in this formula. Specifically, he is certified with NSCA, CSCS, ACE PT, CSEP and holds an undergraduate degree in exercise physiology.

What drew us closer to his career profile are his contributions toward a handful of formulations, some of which are delivered by names such as Muscle Tech, NxLabs, Slimquick, ADS, BlueStar Nutraceuticals, and Empowered Nutrition.

Formulation Powder
Dosage 1 sachet daily
Money-back guarantee 60-day money-back guarantee.
Ingredients Green tea extract, L-theanine, L-carnitine, Chlorogenic acid, Chromium,
Price $49
Side effects Free from side effects.

KetoCharge

image12

As insinuated in the title, KetoCharge is the best thermogenic fat burner that burns fat for energy production. Consequently, fat storage is said to shrink with time, permitting individuals to reach their weight loss goals.

Unlike conventional fat burners, those founded on the principles of ketosis (i.e., the metabolic state for desirable results) tend to fuel the body with potassium beta-hydroxybutyrate (800mg). So, we are talking about consistent fat burning and preferred hydration levels essential for healthy mental and physical functions.

Losing weight and stubborn fat becomes easy even without diet and exercise with this weight loss pill. All the properties make this the best fat burner.

The makers are none other than Wolfson Brands (UK) Limited, a team of entrepreneurs, nutritionists, scientists, and business explorers who are all passionate about bridging the gap between healthy living and e-commerce through cutting-edge science time-tested strategies.

Formulation Capsules
Dosage 2 capsules a day
Money-back guarantee 60-day money-back guarantee.
Ingredients Sodium BHB, Magnesium BHB, Calcium BHB.
Price $59
Side effects Free from side effects.

Leanbean

image14

The fat burner supplement industry has always tended to the needs of male athletes and consumers, but seldomly that of females. This has been gradually changing thanks to players like Ultimate Life.

In particular, the team at Ultimate Life developed Leanbean, i.e., a natural fat burner initially targeting female bodybuilders, and now females altogether. As an overall brand, Ultimate Life strongly argues that “achieving your goals don’t have to come at a cost.”

The fat-burning ingredients of this best fat burner increase fat oxidation to lose weight naturally. Naturally, these fat burner pills are counted among the top fat burner supplements.

Furthermore, they affirm that the natural way is ideal, permitting Leanbean to help suppress and slash random hunger cries, stimulate metabolism, and ensure hormonal balance.

Formulation Capsule
Dosage 6 capsules daily.
Money-back guarantee 90-day money-back guarantee.
Ingredients Konjac fiber, Chromium Picolinate, Chloride, Zinc, Green coffee bean extract.
Price $59
Side effects Free from side effects.

Meticore

image15

Meticore is a fat burner supplement that has been established on a particular issue reckoned to disrupt weight loss goals. Specifically, the makers made their case for low core body temperature as the culprit, adding that the Meticore fat-burning pills suffice to trigger and supercharge the metabolism for men and women.

After researching the claims made, science has since demonstrated that low core body temperature is a probable cause for unexplained weight gain, which was uplifting and provided some assurance in terms of effectiveness. You can lose fat and shed body fat from the entire body with this supplement while enjoying other health benefits.

Unfortunately, the popular demand for Meticore does not appear to align with the absence of transparency regarding the manufacturing company and supplement’s fact. Without any further clarification, our editorial team simply cannot make a case for this solution.

Formulation Capsules
Dosage 2 capsules
Money-back guarantee 60-day money-back guarantee.
Ingredients African mango seed, Ginger rhizome, Moringa leaf, Citrous bioflavonoids, Chromium picolinate, Vitamin B12, Fucoxanthin.
Price $59
Side effects Free from side effects.

NitriLEAN

image16

NitriLEAN aims to restore bodily hormones, which in turn is imagined to help reach weight loss targets. Precisely, the makers James Carter, Dr. Yuri Petrov, and All-Natural Nutrition explained that nitric oxide levels need to be rectified because they are essential for fat burning. As beautiful as the process of aging is, these levels will exponentially decay, giving rise to unwanted health conditions.

The magical belly fat reduction benefits of these weight loss pills make users count them among the best fat burners. Being one of the best fat burner supplements, this one can burn fat more effectively than other fat-burning supplements can.

If you want to lose weight fast, this fat burner for men is an exclusive option with a 60-day money-back guarantee. The best fat-reducing product helps you burn fat and lose weight faster than you imagine.

Formulation Capsules
Dosage 2 capsules daily
Money-back guarantee 60-day money-back guarantee.
Ingredients Garcinia Cambogia, Bioperine, Cayenne, Beet-root, Green sed extract.
Price $59

Okinawa Flat Belly Tonic

image17

The Okinawa Flat Belly Tonic is one of the best fat burner supplements for anyone looking for weight management, digestion, or energy/vitality supports. Deemed vegan-friendly, this solution is projected to unmask and destroy the root cause of weight gain.

In so doing, the fat-burning processes are believed to not only persist throughout the day but also well into one’s sleep. Imagine the strength of this formula if it can activate metabolic rates to such lengths!

For instance, very little is known on the Flat team. Then there’s the lack of a detailed ingredient list coupled with unknown concentrations per serving. Ultimately, we are surprised to see popular demand for the Okinawa Flat Belly Tonic, given that more research is needed.

Formulation Powder
Dosage One scoop daily.
Money-back guarantee 90-day money-back guarantee.
Ingredients Shilajit extract, Ginger root, White tea extract, Green tea extract, Bitter melon extract.
Price $89
Side effects Free from side effects.

PhenGold

image18

At Swiss Research Labs Limited, celebrating scientific discoveries and clinically effective doses is just a fraction of what individuals expect.

They want everyone to know that customer wellness is of utmost priority, which is why Swiss Research Labs Limited invested heavily in research and development to bring PhenGold to the market. As a dual-purpose weight loss formula, PhenGold might induce weight loss when coupled with healthy meal portions and physical activity.

The latter needs stress, as most companies tend to tempt consumers by insisting that diets and exercises are unnecessary, but that is far from the truth.

Formulation Capsules
Dosage 3 capsules a day
Money-back guarantee 100-day money-back guarantee.
Ingredients Cayenne Pepper, BioPerine black pepper, L-tyrosine, Rhodiola Rosea, L-Theanine, Green coffee, Green tea leaf extract.
Price $59
Side effects Free from side effects.

PhenQ

image19

Another solution brought to us by the very Wolfson Brands (UK) Limited, PhenQ, is one of the most impressive thermogenic fat burners intended to provide an extra push for men and women who have specific weight management goals.

No matter whether you’re looking for a fat burner for men or a fat burner for women, PhenQ fat-burning pills will surely make you lose weight and burn excess fat without a healthy diet.

By specific, we mean anything from shrinking fat storage and suppressing appetite to blocking fat production and improving mood and energy levels.

Money-back guarantee 30-day money-back guarantee.
Ingredients Capsimax powder, Chromium picolinate, Caffeine, Nopal, L-carnitine fumarate.

Cut

image7

POWHER Cut is portrayed as a unique fat burner for women that carries clinically proven ingredients essential for reducing cravings and caloric intakes, burning fat, supporting normal fat metabolism and boosting energy during exercise.

As a team that decided to take matters into their own hands when very few tailored solutions were available for women, POWHER strongly frowns upon false promises and unrealistic goals. The team shared openly that their solutions don’t overpromise.

They don’t underperform. They just work, enabling women to perform, achieve and realize their ambitions.” How can anyone neglect the fact that Cut reflects the input of scientists and registered dieticians?

Formulation Capsules
Dosage 6 capsules daily
Money-back guarantee 90-day money-back guarantee.
Ingredients Taurine, Beta-alanine, Tyrosine, Lysine, L-citrulline malate, Coconut water.
Price $65
Side effects Free from side effects.

Resurge

image20

The concept for Resurge was brought to us by John Barban, the same maker of Java Burn. He reasons that sleep deprivation is detrimental to our metabolism and reparation processes. Recall that during our sleep, the body recoups from an exhausting day, and when this isn’t fulfilled as needed, our health is compromised in unimaginable ways; weight is one of them!

If you’re concerned about belly fat, this fat burner comes among the natural fat burners that aid in losing weight without a diet and exercise plan.

With Resurge, deep sleep might be achieved. Thus, increases in human growth hormone can be anticipated (i.e., aids in muscle building and reparation of bodily tissues) while supercharging the metabolism.

Formulation Capsules
Dosage 1 capsule daily.
Money-back guarantee 30-day money-back guarantee.
Ingredients Melatonin, L-Tryptophan, Chamomile, Magnesium, Valerian, Goji berry.
Price $69
Side effects Free from side effects.

These are the popular thermogenic fat burner supplements that can reduce stubborn belly fat and induce your weight loss journey. Most fat burners claim to burn stored fat, but these best fat-burning supplements do that in reality. Apart from losing weight, you will be able to retain muscle mass throughout your weight loss journey with these natural fat burners.

Torching Away The Bad Players Using Our Ranking System

From above, it should be apparent that no two solutions are alike. Additionally, a good number of the supposed best lack substance after all. So, how did they manage to make it to our top 2021 guide? Things will make a little more sense once consumers delve through crucial factors within our customizable ranking system, as seen below:

Company & Transparency

As with any supplement, the first two critical factors are company background and transparency. For a team to tout that their solutions are top-notch implies confidence on their end.

So, why should they hide? A lot of the popularly sought supplements in our guide lack even the slightest knowledge of the company. This only raises red flags that need to be reflected upon. Ignoring them can lead to an ineffective solution sold for money-grabbing purposes.

Similarly, transparency ties in with everything and represents a company’s ability to convince consumers. By convince, we mean anything ranging from a supplement’s fact and laying down the processes that led to a supplement to lab testing and sourced ingredients. Failing to fulfill these foundational facets puts a supplement at significant risk for doubt.

Scientifically Backed Ingredients at Clinically Effective Doses

There have been several contradictions surrounding the existence of fat burners, where many ingredients supposedly serve as mere fillers. Given that only a handful has been clinically studied to elicit results, we were on the lookout for such elements. As long as there was some hint of effectiveness in science and clinical dosing, a supplement qualified.

Type of Fat Burner

It turns out that fat burners come in various types, differing in the process to the final goal. Our search led us to appetite suppressants, thermogenic fat burners, fat blockers, and stimulant-free fat burners, all of which have been welcomed with open arms. For those wondering how different these four genuinely are, the first ensures satiety (while preventing binge eating), the second increases body temperature, the third prevents absorption of fats (also preventing fat storage), and the last type is caffeine-free fat burners.

Advertised Benefits

There’s a lot of fun in reading through advertised benefits. While some companies state them as they are expected, others make outlandish claims that are beyond factual. Anything that flaunts fat burning without exercise or healthy lifestyle choices to us is a complete scam. Comparably, companies that avow significant reductions in weight (say beyond 10lbs a month) with just a supplement alone should be questioned to great lengths.

Popularity

Popularity is rarely included in guides like this. Still, we decided to go the extra mile to show everyone that just because a popular supplement doesn’t mean it carries substance. Several internet deals insist on solutions as being “#1 in all of America”, but nothing is usually known about the company or even the concentration of selected ingredients when a closer look is taken. Ultimately, purchasing a supplement with nothing but a significant slash to prices is (most often) equivalent to putting one’s health at risk, and we decided to bring them to light.

Uniqueness

Uniqueness is anything and everything that sets a brand apart from the rest; otherwise, how would we have managed to narrow down our top picks right? Our editorial team sought anything that symbolizes a company’s efforts, such as doctor/physician-formulated, third-party lab testing and availability of results, informative blogs, patented and proven ingredients, money-back guarantees, and contributions toward societal advancements.

Verified Customer Reviews

Verified Customer reviews provide some insight into a thermogenic fat burner under consideration. Our goal wasn’t to only analyze the five-star reviews but also to be extra vigilant regarding the one-star reviews. Why? The latter is a great way to assess any potential side effects, the likelihood of occurrence, and the rate at which one’s health may be compromised. Of course, this wasn’t the make-or-break deal; however, reviews also helped understand the seriousness of side effects, which are rarely discussed.

Value for Money

Value for money is determined based on the number of factors that a supplement fulfills on our ranking system. Price never meant everything, and this holds to this date. Therefore, pricing was the last thing on our minds, and as a result, we succeeded in finding the best fat burners that encompass all financial stances.

The Scientific Outlook: Where Does the Community Stand Regarding Thermogenic Fat Burners?

Things are about to unravel scientifically as we explore fat burners through the lens of clinical trials, studied dosing, and findings accordingly.

This is an unavoidable step because the FDA doesn’t regulate dietary supplements, meaning that manufacturers are not restricted to a set of guidelines. Therefore, if one chooses not to conduct third-party testing, there’s no one to point the finger at them.

To see where our picks stand within the scientific community, we reviewed the top five recurring ingredients. Here’s what there is to learn:

Chromium

Chromium is an essential trace mineral trusted to improve insulin sensitivity while enhancing protein, carbohydrate, and lipid metabolism, explained one source [1]. To what extent do Chromium’s metabolism-boosting effects hold? Another source referenced a more extensive analysis encompassing nine different studies totaling 622 overweight or obese people searching for answers.

In the end, doses of up to 1mg per day led to “very small amounts of weight loss (2.4lbs) after 12 to 16 weeks.” Another in-depth analysis supposedly arrived at comparable conclusions [2].

It was generally highlighted that “chromium picolinate is not effective at producing meaningful weight loss in overweight or obese individuals. It appears to be even less effective in normal-weight individuals, even when combined with exercise.”

Capsicum Extract

Capsicum extract is rich in antioxidants, and anti-inflammatory properties essential for anti-cancer benefits, reports one source [3], but where do we stand regarding fat burning?

One study was conducted to evaluate the effects of capsaicinoids (i.e., a component extracted from capsicum) on body fat and fat mass while factoring in “body habitus, diet, and metabolic propensity.” Seventy-five participants were recruited for this study (ranging between 18 and 56 years). After the 12-week mark, “percent change in body fat after 12 weeks of treatment was 5.91% units lower in CAPs 4mg subjects than placebo [4].”

Caffeine Anhydrous

Caffeine anhydrous is superior to regular coffee because it neither contains water nor does it undergo extensive processing. As summarized by one source, this ingredient can improve athletic performance.

However, the side effects of taking anything in excess can have negative implications. Specifically, individuals may experience vomiting, rapid heartbeat, chest pain, disorientation, seizures, and possibly death [5].

Green Tea Extract

Yet another ingredient with antioxidant properties is green tea. Matter-of-factly, it is probably one of the richest sources known to humankind.

In terms of weight loss, one source explained that green tea contains catechins and caffeine, both of which have been proven to assist in weight loss by stimulating thermogenesis. For people unaware of the term “thermogenesis,” it entails burning calories by producing heat.

Interestingly, the same source referred to an older study with 14 people, where the combination of green tea and guarana extract led to burning an extra 179 calories in the following 24 hours [7].

L-Theanine

Finally, we have L-theanine, an amino acid that has been linked to regulating mood, emotions, cognitive function, and appetite, among others [8]. As for its effect on weight loss, one source noted that L-theanine (which also happens to be inside green tea) could create a savory taste.

This, in turn, might reduce appetite and thus, decrease caloric intake [9]. Additionally, we stumbled upon one piece involving an animal study. In it, the researchers discovered that L-theanine had been proven to promote the browning of white fat (i.e., the wrong kinds) in obese mice [10].

Frequently Asked Questions About Thermogenic Fat Burners

Q: What ingredients should consumers be eyeing in the best fat burners?

A: Based on the claims made in one source, the likes of L-carnitine, green tea, capsicum, and Gymnema Sylvestre extract are the most effective. That said, there are plenty out there, and we encourage everyone to explore and research further into matters.

Q: Are fat burners safe?

A: The best fat burners are generally safe to consume, but there have been reports of mild side effects such as constipation, nausea, gas, diarrhea, and black stools. Infrequent cases include vomiting, abdominal bloating, and intense abdominal pain [12].

Q: Why must fat burners be consumed with exercise and dieting?

A: Fat burners are recommended right before a workout session because this is trusted to activate their fat-burning effects. Some benefits may arise from fat burners alone, but they are likely marginally and cannot be compared to results obtained with healthy eating choices and exercise.

Q: What natural foods constitute fat-burning capacities?

A: One source insists that the likes of beans, beef, yogurt, red bell peppers, broccoli, edamame, and diluted vinegar can help burn belly fat [13]. Others may include chocolate milk, bananas, turkey, cottage cheese, cherries, peanut butter, kefir, almonds, high fiber cereal, string cheese, and protein powder [14].

The Best Fat Burners of 2021 Final Verdict

Ultimately, fat burner supplements may aid in torching away stubborn fat while keeping consumers energized during their workouts. There are four fundamental types out there, each one representing different goals that need to be met.

After investing time into research, we’ve arrived at 21 supplements that have either been supported by our ranking system or popular demand. In the majority of the cases, the ones deemed popular lacked substance, preventing us from sharing our opinion on effectiveness and value for money.

Ultimately, the next course of action would be to assess one’s health, eating habits, and exercise routine and see which of the best fat burners of 2021 resonates the most with one’s respective goals. Until we meet again, we hope our guide provided pointers on how to take weight management goals to the next level.
