Best Fat Burner Supplements for Weight Loss (Compare Top Pills)

Fat burners have been a hot topic of discussion. They are touted for their supposed ability to boost the metabolism, suppress appetite, and help burn fat for energy production purposes. Since then, natural dietary 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 top 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 Top 21 Fat Burners of 2021

As hinted earlier, choosing fat burners 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 introducing our contenders is most sensical. Therefore, without any further delay, here they are:

  • Lean Belly 3X
  • BioFit
  • ExiPure
  • Biotox Gold
  • Burn Lab Pro
  • cAMP Boost
  • CarboFix
  • Cellucor SuperHD Fat Burner
  • CircadiYin
  • Instant Knockout Cut
  • Hunter Burn
  • Java Burn
  • KetoCharge
  • Leanbean
  • Meticore
  • NitriLEAN
  • Okinawa Flat Belly Tonic
  • PhenGold
  • PhenQ
  • POWHER
  • Resurge

Lean Belly 3X

image 13
  • Company/Creator: Beyond 40
  • Starting Price: $59

Lean Belly 3X is touted as an advanced belly-toning formula 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.

The Lean Belly 3X formula has been devised to bring good and bad fats inside a ring so that the latter can be completely knocked out. We were generally convinced by the idea, given that science stands by fat vs. fat combats. All Lean Belly 3X servings signify the importance of Safflower Seed Oil (1500mg), Conjugated Linoleic Acid (1200mg), and BioPerine® (5mg).

BioFit

image 1
  • Company/Creator: Chrissie Miller
  • Starting Price: $69

BioFit is a probiotic supplement designed to populate the gut for weight loss and maximum immunity. The strains qualified for this supplement include Bacillus Subtilis (DE111™), Lactobacillus Rhamnosus, Lactobacillus Casei Lactobacillus Plantarum, Lactobacillus Acidophilus, Bifidobacterium Longum, and Bifidobacterium Breve (for a combined total of 5.75 billion CFUs). 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 manufacturer was their 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 supplement remains a favorite on the internet!

Exipure

image 8
  • 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 brown fat boosting 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. The Exipure supplement deserves to be one of the top fat burner supplements to buy due to its one of a kind formula consisting of Olive Leaf Oleuropein Extract Blend (20% Oleuropein), Concentrated Bee Propolis, Perilla leaf extract 90% luteolin (perilla frutescens), Holy Basil leaf extract 2.5% Ursolic and Oleanolic acids (ocimum sanctum), Phellodendron amurense bark extract (rich in berberine), Kudzu root extract (Pueraria Lobata), Quercetin (quercetum) and White Korean Ginseng root extract 5% ginsenosides (panax ginseng).

Given the risk-free 180 day money back guarantee and all of the free bonuses for buying in bulk (not to mention the savings), it is hard to pass up one of the most popular, science-based fat burner pills available on the market today.

Biotox Gold

image 2
  • 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 Biotox Gold 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.

Burn Lab Pro

image 3
  • Company/Creator: Opti-Nutra Ltd.
  • Starting Price: $59

Opti-Nutra Ltd. is a brand that has been recognized for developing formulations, selecting ingredients, and manufacturing everything with care. Out of all the 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 supplement 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. My numbers on the scale kept improving.” Of course, her results also stem from her hard work and dieting, but Burn Lab Pro had a role to play. The latter is because each serving is said to deliver GTF Chromium (90mcg), Calcium (262.5mg), HMB from Calcium (1500mg), ForsLean® (375mg), Capsimax® (75mg), and BioPerine® (3.75mg).

cAMP Boost

image 4
  • Company/Creator: Nutraville
  • Starting Price: $67

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. This supplement is trusted to free the body of an enzyme called PDE-4, which blocks fat-burning signals sent to a messenger called cyclic adenosine monophosphate (cAMP). Nutrients essential for its elimination include Grapefruit Extract (450mg), Grains of Paradise Extract (40mg), and Black Pepper Extract (5mg).

CarboFix

image 5
  • Company/Creator: Gold Vida
  • Starting Price: $49

CarboFix is advertised as an all-natural formula designed to fight off belly fat, uncontrollable weight gain, and random hunger cries and cravings. By combining six key ingredients, this supplement is trusted to activate AMPk. In so doing, individuals can supposedly “indulge in favorite carbs guilt-free.” 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. In fact, each serving contains Chromium (200mcg), Berberine HCL (400mg), Cinnamon (100mg), Benfotiamine (80mg), Naringin (50mg), and Alpha Lipoic Acid (50mg). Hence, is Gold Vida a trustworthy brand? Without any further information on the company, we simply cannot arrive at a sound conclusion.

SuperHD Fat Burner

image 21
  • Company/Creator: Cellucor
  • Starting Price: $28

SuperHD is a thermogenesis-inducing fat burner 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. So, what made the cut? A 193mg-SuperHD Thermogenic & Sensory Blend (i.e., N-Acetyl L-Tyrosine, Amla Fruit Extract, Dandelion Root, Yohimbe, Capsimax, Toothed Clubmoss, and Rauwolfia), Caffeine Anhydrous (160mg), and Green Tea Phytosome (150mg). The ingredient 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.

CircadiYin

image 6
  • Company/Creator: CircadiYin
  • Starting Price: $69

CircadiYin is a dual-purpose supplement that promotes sleep to lose weight. The unnamed makers affirm that the included ingredients can go as far as resetting our circadian rhythm so that metabolic function can be rectified. At the time of writing, each serving is revealed as celebrating a 905mg-Circadian Proprietary Blend consisting of L-Tryptophan, Goji, Chamomile, Lemon Balm, Passionflower, L-Taurine, Hops, St. John’s Wort, GABA, Skullcap, L-Theanine, Ashwagandha, Inositol, and 5-HTP. Other ingredients include Melatonin, Calcium, Magnesium, and Vitamin B6.

Their claims on prioritizing sleep have been fulfilled through this formula. 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.

Instant Knockout Cut

image 10
  • Company/Creator: Roar Ambition Ltd.
  • Starting Price: $59

With emphasis placed on scientific evidence and reliability, Instant Knockout Cut is a fat burner that promotes lean muscle mass, 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.”

Thus, what is it about Instant Knockout Cut that is likely to convince people? The secret rests in the formula, which embodies the positive effects of Vitamin D3 (45mcg), Vitamin B6 (5mg), Vitamin B12 (10mcg), Glucomannan (1800mg), Green Tea Extract (500mg), Caffeine Anhydrous (300mg), L-Theanine (100mg), Cayenne Powder (100mg) and Black Pepper (10mg) on body fat, and metabolism.

Hunter Burn

image 9
  • Company/Creator: Roar Ambition Ltd.
  • Starting Price: $75

We meet Roar Ambition Ltd. yet again, but this time for a 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. To be more precise, each serving (i.e., six capsules) contains Vitamin D3 (75mcg), Konjac Root Extract (3g), White Kidney Bean 20:1 Extract (500mg), L-Theanine (200mg), Matcha Green Tea (200mg), and Cayenne Pepper (125mg).

Java Burn

image 11
  • Company/Creator: John Barban
  • Starting Price: $49

Java Burn is a 100% natural coffee add-on 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. 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. Talk about a well-rounded career, with the opportunity for more in the future! Lastly, we have Java Burn Coffee, encompassing the likes of Green Tea Extract (300mg), Chromium (20mcg), L-Theanine (100mg), L-Carnitine (100mg), Green Coffee Bean Extract (200mg), Vitamin D3 (20mcg), Vitamin B6 (1mg), and Vitamin B12 (5mcg).

KetoCharge

image 12
  • Company/Creator: Wolfson Brads (UK) Limited
  • Starting Price: $59.95

As insinuated in the title, KetoCharge is a ketogenic dietary supplement 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.

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. Matter-of-factly, the CEO, Stewart Lochrie, wants everyone to know that he and his team will work tirelessly “to inspire positive lifestyle change.”

Leanbean

image 14
  • Company/Creator: Ultimate Life
  • Starting Price: $59.99

The supplements 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.”

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. Each serving is said to fuel the body with Vitamin B6 (3.72mg), Vitamin B12 (6.4mcg), Chromium (120mcg), Green Coffee (600mg), Acai Berry (800mg), Green Tea Extract (200mg), Turmeric (200mg), Glucomannan (500mg), Garcinia Cambogia (400mg), Cayenne (60mg), Black Pepper (20mg), and Raspberry Ketones (8mg).

Meticore

image 15
  • Company/Creator: Meticore
  • Starting Price: $59

Meticore is a dietary 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 formula suffices to trigger and supercharge the metabolism for men and women. The ultimate question now is, “How does one address low core body temperature?” Simple, at least according to the makers, who believe that the combined effects of six natural ingredients are all that’s needed. These include Turmeric, African Mango, Ginger, Moringa, Bioflavonoids, Fucoxanthin, Vitamin B12 (10mcg), and Chromium (35mcg).

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. 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.

NitriLEAN

image 16
  • Company/Creator: All Natural Nutrition
  • Starting Price: $59

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. For people wondering what the process of heightening nitric oxide levels may entail, our search led to a serving size highlighting the benefits of Beet Root (100mg), L-Citrulline (220mg), Hawthorn Extract (100mg), Green Tea Extract (500mg), Garcinia Cambogia (100mg), Cayenne Pepper (50mg), Grape Seed Extract (50mg), and BioPerine (5mg).

Yet another supplement founded on scientific reasoning, the entire NitriLEAN team appears to have fallen short on transparency. We arrived at this conclusion because of our unsuccessful attempt at verifying the credentials of the supposed makers and manufacturing companies. Hence, we encourage interested parties to investigate this solution before proceeding thoroughly.

Okinawa Flat Belly Tonic

image 17
  • Company/Creator: Flat
  • Starting Price: $89

The Okinawa Flat Belly Tonic is a suitable supplement 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! Well, our curiosity piqued as well, leading to the unearthing of Green Tea (EGCG), Inulin, Momordica Charantia, Hibiscus, Acai Berry, and Aronia Berry. As interesting as this alleged formula might be, several gray areas make us uneasy. 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.

PhenGold

image 18
  • Company/Creator: Swiss Research Labs Limited
  • Starting Price: $74.99

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. Every PhenGold serving reflects the union between Vitamin B3 (15mg), Vitamin B6 (1.3mg), Vitamin B12 (24mcg), Green Tea (500mg), L-Tyrosine (300mg), Rhodiola (250mg), L-Theanine (250mg), Caffeine Anhydrous (225mg), Cayenne (200mg), DMAE Bitartrate (150mg), Green Coffee (100mg) and BioPerine® (5mg).

PhenQ

image 19
  • Company/Creator: Wolfson Brands (UK) Limited
  • Starting Price: $69.95

Another solution brought to us by the very Wolfson Brands (UK) Limited, PhenQ, is a dietary supplement intended to provide an extra push for men and women who have specific weight management goals. By specific, we mean anything from shrinking fat storage and suppressing appetite to blocking fat production and improving mood and energy levels. At first glance, individuals are likely to learn that PhenQ encompasses clinically effective doses coupled with studies that educate consumers on how the supplement might work. Each ingredient, patented or not, has been included, reflecting their commitment to research and development. Hence, what makes PhenQ so potent? Elements such as L-Carnitine Fumarate (150mg), Caffeine Anhydrous (142.5mg), A-Lacys Reset (25mg), Nopal derived from Capsicum Extract (20mg), Niacin Powder (8mg), Piperine Extract (4.5mg), and Chromium (3mg).

Cut

image 7
  • Company/Creator: POWHER
  • Starting Price: $65

POWHER Cut is portrayed as a unique cutting supplement that carries clinically proven ingredients essential for reducing cravings and caloric intakes, 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 realise their ambitions.” How can anyone neglect the fact that Cut reflects the input of scientists and registered dieticians?

Seeing the versatility of experts involved in formulating POWHER Cut, it only makes sense to dive into the contents of this dietary supplement, right? Well, by the looks of it, each serving contains Magnesium (33.33mg), Selenium (18.22mcg), Chromium (40mcg), Glucomannan (1000mg), Choline (30mg), and Natural Caffeine (33.33mg).

Resurge

image 20
  • Company/Creator: John Barban & Adonis Lifestyle
  • Starting Price: $49

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!

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. What might a deep sleep formula entail? Each serving is said to contain L-Arginine (1200mg), L-Lysine (1200mg), L-Theanine (200mg), Ashwagandha (150mg), Griffonia Simplicifolia (100mg), Melatonin (10mg), Magnesium (50mg), and Zinc (15mg).

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 ensure 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 supplement 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. In all honesty, we’ve come across several highly-priced solutions yet don’t even house the fundamentals. Therefore, pricing was the last thing on our mind, and as a result, we succeeded in finding fat burners that encompass all financial stances.

The Scientific Outlook: Where Does the Community Stand Regarding 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 that 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].

That said, one study looked at the effects of both caffeine and caffeine anhydrous on strength and sprint performance. In the end, the researchers found that “neither [caffeine] nor [caffeine anhydrous] improved strength outcomes more than [the placebo].” They further explained that “while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise [6].”

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 Fat Burners

Q: What is a fat burner?

A: A fat burner is a supplement that claims to increase fat metabolism, energy consumption, fat oxidation, and weight loss while possibly preventing fat storage from persisting.

Q: How do fat burners work?

A: According to a piece expounding on the different layers of fat burners, it has been argued that they are typically formulated to stimulate hormonal reactions in the body, which in turn help with breaking down fat. The final result? A by-product that is often desired for fueling purposes. Of course, the exact mechanism varies based on the type of fat burners under question, but in general, it starts and ends similarly [11].

Q: Which fat burners are helpful?

A: Refer to our top picks for 2021, as they have been reviewed, tested, and confirmed to have a certain level of impact on shrinking and eradicating fat. Mind you that some aren’t as great as we would have liked but have been included to showcase the different ways scams may take form.

Q: How much weight can one expect to lose with fat burners?

A: When paired with rigorous training and healthy eating cycles, fat burners can lead to anywhere between 1 to 3lbs of weight loss per week. For continued results, individuals will need to be consistent in their lifestyle choices. Otherwise, a rebound effect is highly plausible.

Q: How long does it take to see results with fat burners?

A: As seen in most scientific evidence provided above, a minimum of 12 weeks is highly recommended for results to unravel gradually.

Q: What ingredients should consumers be eyeing in 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: 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: Are fat burners effective alone or when coupled with dieting and exercise?

A: Fat burners alone are rarely enough! If people think they can get away with exercising or eating healthy while on fat burners, they’ve got several surprises coming their way, some of which include weight gain, intact belly fat, and the absence of desirable results.

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].

Q: Are fat burners legal?

A: As long as they do not contain any banned substances, they are deemed legal. It is important to note that the FDA does not approve dietary supplements unless it contains a new dietary ingredient that has not been marketed in the US before.

Q: Are fat burners worth it?

A: It can be worth it for people who are on their last stretch of fat that needs burning, but once again, on their own, they are meaningless.

The Top 21 Fat Burners of 2021 Final Verdict

Ultimately, fat burners 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. By substance, we mean very little available on the manufacturer, supplement’s fact, or the use of outlandish claims to lure in consumers. This goes to show that even those that appear truthful at first glance are far from it! We encourage everyone to actively do their due diligence before investing – seeing how our health will be on the line otherwise!

A ranking system can put things into perspective and facilitate a smoothened elimination process while unmasking the scammers. Our approach is not set in stone; hence, individuals can either add or remove factors as seen fit. While we might have repeated ourselves several times now, individuals must realize three things; first, not all fat burners are made equally; second, not all ingredients have been clinically tested. Most of all, fat burners elicit close to nothing on their own. Ultimately, the next course of action would be to assess one’s health, eating habits, and exercise routine and see which of the top 21 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.
