Whenever summer is fast approaching, most people begin to think about how to sculpt their ideal body and show it off to the world. Unfortunately, even the strictest diets and most hardcore workouts will eventually hit a limit, and you may find yourself struggling to shed the last few stubborn pounds of fat.
Fat burning supplements are a great tool to help you overcome plateaus or enhance your ongoing weight loss journey. But as with all supplements, finding the best thermogenic fat burner can be more challenging than expected. Not only do you need to sift through hundreds of products that don’t work, but you also need to find a fat burning supplement that works in tune with your body for the best possible results.
We’ve looked at many of the most popular thermogenic fat-burner supplements on the market and found several whose results match their claims. Whether you’re just starting your weight loss journey or need an extra push to help you achieve your fat loss goals, here are some of the best fat burning supplements.
Top 5 Best Fat Burners on the Market in 2022
- PhenQ: Best fat burner supplement overall
- PhenGold: Best for stubborn belly fat
- Leanbean: Best fat burner for women
- Instant Knockout Cut: Best fat burner for men
- TrimTone: Best for appetite suppression and energy
#1. PhenQ: Best Fat Burner Pills Overall
PhenQ is the flagship fat burner from Wolfson Berg Limited, a supplement manufacturer known for its health and wellness products. PhenQ contains several natural ingredients that target the fat burning process from five angles. This combination of effects makes PhenQ ideal for anyone struggling with weight loss, no matter which aspect of the process you’re struggling with.
According to the manufacturer, PhenQ offers the following benefits:
- Enhanced fat burning
- Appetite suppression
- Slower fat production
- Boosted energy
- Improved mood
These benefits work together to tackle all of the difficulties most people face during their weight loss journey.
PhenQ combines several well-known weight loss ingredients in a unique blend that enhances your body’s natural fat burning response.
α-Lacys Reset is PhenQ’s proprietary ingredient that boosts thermogenesis — increasing body heat — resulting in faster metabolism. A faster metabolism will need to burn more calories per day, even if your activity levels stay the same. The result is a more significant calorie deficit, meaning that you’ll find it easier to burn fat faster without making significant changes to your diet or workout routine.
According to small-scale clinical studies, α-Lacys Reset may help individuals lose weight while increasing their lean muscle mass. Some studies also suggest the beneficial effects of ALA on conditions related to obesity, such as metabolic syndrome and diabetes.
Capsimax powder contains a blend of pepper extract, vitamin B3, and capsicum that enhances thermogenesis. Piperine is also a bioavailability enhancer, meaning that you’ll get better uptake of—and see better results from—all of PhenQ’s other ingredients.
Nopal extract contains high amounts of fiber and amino acids and acts as a natural appetite suppressant. This water-absorbent fiber stays in your stomach and intestines, helping you feel fuller for longer while flushing fluids from tissues and reducing water weight.
Caffeine offers many weight loss benefits, including appetite suppression, boosting thermogenesis, and reducing fatigue.
L-carnitine is an important amino acid that promotes fat metabolism. By helping your body turn fat stores into energy, this compound enables you to shed weight faster while also keeping your energy levels up.
PhenQ has a 60-day money-back guarantee if you’re not 100% satisfied with your results. The manufacturer also offers free global shipping and multi-buy discounts to save you up to 30% off your purchase price for larger orders.
PhenQ doesn’t contain soy, gluten, or GMOs and is suitable for vegans and vegetarians due to its 100% plant-based formulation.
#2. PhenGold: Best Belly Fat Burner
PhenGold is a weight loss supplement from Swiss Research Labs, Ltd. This reputable manufacturer makes a wide range of weight loss supplements in its FDA-approved and GMP-certified laboratories.
According to the official PhenGold website, the fat burner supplement offers the following benefits. It:
- Improves your body’s ability to burn fat faster and more effectively
- Boosts your metabolism, helping your burn more calories per day
- Curbs cravings and hunger to help you stay in control of your eating
- Increases your energy and focus
- Enhances your mood, helping you stay motivated and focused on your weight loss goals
PhenGold combines several natural ingredients into a unique blend that targets weight loss from several angles. These ingredients work synergistically, meaning that you get better results from the combination of ingredients than you would from a single compound.
Green Tea Extract
Green tea leaf extract contains several compounds that promote weight loss by boosting your body’s metabolism and making it easier to burn fat. It also contains antioxidants that offer additional health benefits in addition to the extract’s weight loss effect.
Green Coffee Bean Extract
Green coffee beans contain several unique compounds that disappear during the roasting process. One, chlorogenic acid, may reduce sugar and fat absorption in the intestine. By letting these sugars and fat pass through your body, you reduce the number of calories your body takes in and increase your daily caloric deficit.
Dimethylethanolamine, or DMAE, is a nootropic that may positively affect mood and improve brain function. The compound works by increasing the production of a neurotransmitter — acetylcholine — responsible for controlling sleep, muscle contractions, and memory.
L-theanine is a vital amino acid involved in stress response. It works as an adaptogen, helping your body adapt to stress and deal with anxiety while also potentially improving your mood and ability to concentrate.
Additional ingredients include:
- Rhodiola rosea
- Cayenne pepper
- Vitamins B3, B6, and B12
PhenGold’s formulation is soy, gluten, dairy, and GMO-free and contains only vegan and vegetarian-friendly ingredients. The manufacturer also offers a 100-day money-back guarantee if you buy a three-month supply and free global shipping. The website also has generous multi-buy discounts that can result in up to 70% savings on your monthly supply.
#3. Leanbean: Highly Rated Fat Burner for Women
Leanbean is a fat burner for women that focuses specifically on the weight loss challenges that many women struggle with the most. According to several studies, women have a more challenging time dealing with cravings during dieting — while men can use willpower to dismiss their cravings, women’s cravings often return stronger than ever. Leanbean aims to address this unique challenge by focusing on appetite suppression instead of thermogenesis.
According to the manufacturer, Leanbean offers the following benefits:
- Increased confidence
- Improved toning
- A boost in energy
- A healthy body
It’s also one of the few stimulant-free fat burners on the market, with no added caffeine or other stimulants that may cause jitteriness or anxiety.
Leanbean only contains four ingredients that contribute to weight loss. These support your body’s normal fat metabolism, allowing you to burn excess fat while maintaining a reduced calorie intake.
The main ingredient in Leanbean, glucomannan, is a natural water-soluble dietary fiber isolated from the root of the konjac plant. Glucomannan is an excellent appetite suppressant as it absorbs water in your stomach, making you feel much fuller for longer without any additional calorie intake. It’s one of the few clinically-proven natural appetite suppressants that can help women stay on top of their diets without having unwanted sugar cravings.
Choline is an essential compound in regulating homocysteine and fat metabolism. The body doesn’t produce enough choline itself, making it an essential nutrient that you need to get from your diet. You may struggle to get adequate choline during a restricted diet, and supplementation supports your body’s natural systems.
Additional supporting ingredients include:
- Vitamins B6 and B12 to reduce tiredness and fatigue
- Chromium picolinate to maintain normal blood glucose levels
- Zinc to maintain protein synthetics and normal fat and carbohydrate metabolism
- Turmeric to promote thermogenesis
- Piperine to improve the bioavailability of the other ingredients
- Green coffee to increase energy levels and help your body burn stored fat
As the premier fat burner for women, Leanbean comes with a 90-day money-back guarantee if you buy the complete bundle. All Leanbean products come from FDA-registered, GMP-certified facilities, ensuring that you get a high-quality, reliable supplement.
Leanbean uses a tracked delivery service and offers free worldwide shopping if you buy the Complete Bundle. This bundle comes with a great multi-buy discount and is the best offer for a three-month supply of this excellent fat burner for women.
#4. Instant Knockout Cut: Top Thermogenic Fat Burner for Men
Instant Knockout Cut is a weight loss supplement aimed at professional and amateur athletes looking to get in fighting condition quickly. It’s rapidly taken off as the premium fat burner for men due to its results and innovative formulation. It also helps preserve muscle mass during a cut, making it an ideal fat burner for men who want to show off their hard-earned physique.
Instant Knockout offers a complete weight loss system that combines its powerful thermogenic fat burner with a complete meal replacement for best results. However, many people have found they get amazing results with the fat burner without needing the meal replacement as well.
According to the official site, Instant Knockout Cut offers the following benefits:
- Speeds up your metabolism
- Reveals sculpted muscle
- Makes it easier to cut and shred
Instant Knockout Cut contains nine fat burning ingredients that provide appetite suppression and a metabolic boost for maximum weight loss potential. The supplement is in its second iteration and builds on the results and experiences of athletes who used Instant Knockout v1.
A natural appetite suppressant, glucomannan is excellent at helping athletes maintain control of their diet during a challenging cut. This dietary fiber works by absorbing water and expanding in the stomach, which fools your stomach into thinking it’s fuller for longer.
L-theanine is an important amino acid with a vital role in mood regulation and sleep quality. It helps athletes cope with the stresses that may trigger overeating and calm down any jitters or late energy slumps associated with caffeine or other stimulants.
Cayenne Pepper Seeds
Cayenne pepper acts as a thermogenic fat burner, forcing the body to produce more heat and burn more calories. Some studies also show that cayenne pepper extract may even improve insulin sensitivity, enhancing energy storage and use.
Green Tea Extract
In addition to being a potent thermogenic agent, green tea extract also acts as a mild appetite suppressant. Its antioxidant properties offer additional health benefits, protecting your body from free radicals that can cause harmful oxidative damage.
Additional ingredients include:
- Vitamin D3
- Vitamin B6
- Vitamin B12
- Black pepper extract
Instant Knockout uses FDA-registered facilities to produce its supplements, ensuring high-quality, reliable products. All ingredients are considered safe by the FDA and naturally sourced, minimizing the chance of unexpected side effects.
Buying Instant Knockout Cut on the official site allows buyers to take advantage of special bulk buy discounts and free add-ons. These may include detailed nutrition e-books and one exercise program video to help you achieve a four-month body transformation. Even better, the manufacturer offers free worldwide shipping if you choose the four-month supply bundle.
#5. Trimtone: Best for Appetite Suppression and Energy
Trimtone is a natural belly fat burner supplement that tackles fat burning through several different mechanisms, including boosting metabolism, burning stubborn body fat, crushing cravings, and boosting your energy levels.
Trimtone’s manufacturer, Swiss Research Labs, is an experienced dietary supplement manufacturer and has developed similar natural fat burners such as PhenGold. However, Trimtone is a fat burner for women and aims to address the unique challenges that hold women back from losing weight.
According to the manufacturer, Trimtone offers the following fat burning benefits:
- Burn stubborn body fat and unlock body confidence
- Curb cravings and stay on track with your diet goals
- One-a-day formula makes taking a weight loss pill simple
Trimtone uses 100% natural ingredients, with no fillers or unnecessary ingredients to pad out the label.
Caffeine increases thermogenesis, the rate at which your body burns calories. It also speeds up the breakdown of fat, making it an effective fat burner for people looking to increase their calorie deficit and speed up their results.
An added benefit of caffeine is that it increases energy. Many people find that they get tired during prolonged calorie restriction, and getting that extra boost can help you maintain your optimal level of activity.
Grains of Paradise
Grains of paradise activate brown adipose tissue (BAT). This type of fatty tissue raises your body temperature and may also regulate blood sugar levels. By keeping your blood sugar levels constant, you’re less likely to experience crashes or food cravings during the day, making the dieting experience significantly easier to handle.
Many women struggle with food cravings, and having an appetite suppressant is a key component of an effective weight loss supplement. Glucomannan is a dietary fiber that expands in your stomach, helping you feel fuller for longer without consuming any additional calories.
It also helps flush excess water from your muscles, helping you develop a more cut look when you start to lose fat and reveal lean muscle.
The supplement also contains two important plant extracts, namely:
- Green tea extract
- Green coffee bean extract
In addition to free global shipping, if you order three or more bottles, Trimtone comes with a 100-day money-back guarantee as long as you buy more than one month’s supply.
All Trimtone products are made in the USA in GMP-certified facilities, ensuring you get reliable products every time. The manufacturer also offers a generous bulk-buy discount that can save you up to 40% on your order price.
What Are Fat Burning Supplements and How Do They Work?
Losing weight is all about burning more calories than you consume, forcing your body to raid its stored fat for energy. Fat burning supplements can help you tackle the problem from multiple angles — some will suppress your appetite, making it easier to restrict your calorie intake, while others will force your body to burn calories faster.
Thermogenic fat burners work by slightly raising your body temperature and speeding up your metabolism. Every person has a basal metabolic rate or the number of calories you need to burn every day simply to stay alive. Raising your body temperature also raises your BMR, meaning that your body needs more calories to maintain its core temperature and physiological activities. By raising your calorie needs and keeping your diet the same, you increase your daily caloric deficit, kickstarting the fat burning process and making it slightly easier to lose belly fat.
Appetite suppressants are the second type of popular fat loss supplement, and they work by limiting your calorie intake. Some of these dietary supplements target hunger and fat burning hormones, while others fill up your stomach with low-calorie “fillers” such as dietary fiber. Because you don’t feel hungry, you’re more likely to stick to your healthy diet, and the longer you stay on top of your deficit, the higher your chances of losing weight and hopefully keeping it off.
The best fat burner supplements combine these two mechanisms into one pill. Some natural fat burners will also include ingredients that improve energy and mood, which often take a nosedive during a strict weight loss diet. The more aspects of fat loss a supplement targets, the better it is at helping individuals lose weight.
How We Ranked the Top Fat Burner Pills
Finding the best fat burning supplement can be a considerable challenge. While many products promise amazing results in burning fat and sculpting the perfect body, few can back up their claims. And many thermogenic fat burners have similar formulations and ingredients, making it even more difficult to differentiate between a good fat burning supplement and a great one.
In our search for the best fat burner supplement, we took a close look at manufacturer claims, ingredients, and several other factors to identify which supplements are worth your time and money. We looked at four key aspects when ranking these supplements and finding the best ones on the market today.
All high-quality fat burners share one thing in common: ingredients with some scientific backing for their weight loss effectiveness. In general, we looked for ingredients, such as green tea extract, green coffee bean extract, and glucomannan, that have several studies showing that these compounds have a statistically significant effect on humans.
Many of the best weight loss pills claim that their ingredients are “clinically proven” to work but will only cite one or two studies where the results are less than convincing. While that’s not to say that these ingredients don’t work at all, it’s better to approach them with a healthy dose of skepticism until more studies show a clearer picture.
When looking for an effective natural fat burner, it’s important to consider how certain fat burning ingredients work together. For instance, some of the most effective fat burners will combine thermogenic enhancers with an appetite suppressant or fat oxidation booster for a multi-pronged approach instead of simply relying on one mechanism of action.
Many unscrupulous supplement manufacturers make bold claims about the benefits of their products, but with little evidence to back these claims up.
Even the best belly fat burner in the world can’t perform miracles, so we prefer supplements that make realistic and reasonable claims. Instead of claims such as “lose 20 pounds in one week!” we looked for fat burning pills that promoted sustainable results and realistic options to help customers lose weight. We also avoided any supplements that promised to target certain regions, like getting rid of abdominal fat or thigh fat, as people will lose weight in these regions according to their unique biochemistry and genetics.
The best way to find weight loss pills that actually work is to look at customer reviews. These reviews are also a great place to see if a product has any potential safety issues or common side effects.
When looking at customer reviews, we made sure to look at overall trends instead of one or two very positive or very negative reviews. Burning fat is a complex process, and not everyone responds to fat burner supplements in the same way. However, if most people say they say a result and shed stubborn fat, then it’s a good indicator that a product is worth a try.
We also made sure to look at current formulations. Instant Knockout Cut, a popular fat burner for men, recently released the second version of their supplement, so we only looked at recent reviews to see how the new version compares to the old one. It also lets us see if the new fat burner has any drawbacks compared to the old formulation.
Price and Guarantee
A supplement’s price is a good indicator of its quality. Rock-bottom prices are often an indicator of poor-quality products, as many of the natural ingredients in the best weight loss supplements are expensive to source. Cheap products will probably have fillers and sub-standard quality products, making them a waste of your money and time.
According to this article on Observer, it’s also a good idea to avoid fat burning pills that are more expensive than average. These will often contain the same ingredients as more affordable fat burners but at a higher markup and flashier marketing.
Most of the best belly fat burners will offer a 60-day money-back guarantee if you’re not 100% satisfied with your results. As people respond differently to weight loss supplements, having a money-back guarantee means that you can try a product without worrying that you’ll have wasted your money if it doesn’t work. However, be sure to read the fine print, as manufacturers only offer these guarantees on bulk offers or certain products. Most will also require that you pay for shipping and won’t include this payment in your refund.
Things to Consider When Choosing the Best Fat Burner
We hope that our list of top fat burning supplements has helped you narrow down your choices to a few options with proven track records. However, while all of these will help you lose weight, some may work better for you than others, and knowing how to evaluate dietary supplements can help you choose the best belly fat burner for your particular needs.
Price per Serving
Gauging the true value of weight loss supplements can be tricky because they vary dramatically in dosages. Some weight loss pills require that you take four or more per day, while others only need one in the morning. If both products cost the same, you’ll get much less value from the first product that you’ll use four times faster.
A good way around this is to calculate the price per serving or price per month. The good news is that high-quality fat burning supplements work based on monthly supply instead of the number of capsules in a bottle, making it much easier to calculate the true price of taking this supplement in the long run.
All of the best fat burners have a refund policy, but it’s always a good idea to read the fine print. Some supplements may require that you send back any opened and unopened bottles and pay for this shipping, while others have restrictions on the products they’re willing to refund.
Fat burner supplements can take several months to work, and it’s important to factor this into the refund policy. If a company offers a 30-day money-back guarantee, it may be too short for you to adequately decide if the product works or not. Look for fat burners with longer refund windows that give the product enough time to work.
A clean label refers to a fat burner with a completely transparent ingredient list. Some manufacturers will hide ingredients in proprietary formulas, making it difficult to figure out what’s really in the supplement. In some cases, these opaque names may protect a patented formula, while in others, it may be to hide chemicals and fillers.
In most cases, reputable fat burner supplement manufacturers will stick to clean labels. The only exception in our list is PhenQ, which has α-Lacys Reset (a proprietary blend) as its primary ingredient. However, the full formulation of α-Lacys Reset is available on request and in the clinical studies using the ingredient, showing that Wolfson Berg has nothing to hide.
Most reputable fat burner supplements will use clinically-backed ingredients in their products, but it’s also vital that these ingredients come in the right concentration.
Correct dosing is essential to making the best thermogenic fat burner possible. Too low a dose won’t have any effect, while too high a dose means wasting valuable ingredients and potentially creating unwanted side effects.
But how do you know what the right dose is? Scientific studies will always mention ingredient amounts, so it’s just as simple as checking the literature. For instance, studies show that 3 g of glucomannan per day is an effective dose, so aim for fat burners with that amount in a serving while allowing for a bit of wiggle room.
High-quality weight loss supplements will aim to use natural and ethically-sourced ingredients wherever possible, especially in the case of extracts and plant-based ingredients.
That said, there are some limitations that manufacturers have to consider when developing their fat burner. Most vitamins, fatty acids, minerals, and amino acids found in supplements are manufactured in a lab. However, that doesn’t mean that they’re unhealthy or dangerous — in fact, synthetic nutrients are often more pure and consistent in quality than those derived from extracts and isolates.
Stimulants are a huge component of many of the best fat burners on the market, as they’re excellent thermogenic boosters and appetite suppressants. However, some people get unpleasant side effects from stimulants, including anxiety, insomnia, and jitteriness.
When looking for stimulants in your weight loss pill, make sure to note the presence of green tea and green coffee beans, and caffeine. Both green tea and green coffee beans also contain a hefty dose of stimulants, and when combined with added caffeine, they may be too much for sensitive individuals. This also applies if you’re taking a green tea supplement — consider using a stimulant-free fat burner to prevent unwanted side effects.
How Much Do Good Fat Burners Cost?
Good fat burners tend to cost between $50 and $70 for a month’s supply. However, many manufacturers offer bulk-buy discounts or subscription models that reduce this monthly cost dramatically.
We recommend buying individual bottles while still shopping around for the best fat burner for your needs and then switching over to these discount options once you’ve found your ideal natural fat burner.
Are Fat Loss Supplements FDA Approved?
No. Since natural fat burners are dietary supplements and not prescription medicines, they don’t need FDA approval. This means that manufacturers don’t need to prove that their product works through clinical trials or undergo stringent quality control.
However, it’s essential to shop around for a manufacturer with FDA-registered facilities, as this will ensure that their fat burning supplement meets several quality standards for reliability and consistency.
Can Fat Burner Pills Help You Lose Weight Without Diet and Exercise?
Not really. Fat burners contain ingredients that can enhance the effects of fat burning hormones and metabolism, but these aren’t enough to help you lose weight alone. These natural ingredients work very gently and subtly to burn off stubborn belly fat, which is why natural fat burners are so safe to use and don’t have harsh side effects like prescription weight loss pills.
Fat burners are supplements, and they work best as a supplement to a healthy diet and regular exercise routine to help you lose weight. Fat burners are also a useful tool in preventing unwanted weight gain when you start returning to a calorie-neutral diet or when you need to take a couple of weeks away from your normal exercise routine.
How Does it Take to Lose Weight with Thermogenic Fat Burners?
Results vary from person to person, depending on how fast they normally burn fat, their current exercise and diet habits, and even the amount of excess fat they have.
Most people see results within one to two months of starting a new fat burner. Some people may see instant fat loss, while others see a gradual change in their overall body composition over several months. Most people may also see a dramatic shift in the scale within the first week or two during a diet, but it’s essential not to get too excited as this is usually due to water weight loss and not actual fat loss.
How to Get the Best Results with Fat Burning Pills
The key to weight loss is, first, to lock in your diet and exercise routine. The goal is to create a sustainable caloric deficit of between 100 to 500 calories per day, which requires eating a healthy diet and moving around every day. By creating sustainable habits, you also avoid the potential for rapid weight gain once you stop your current eating plan.
It’s important to note that even the best fat burners won’t miraculously help you shed stubborn fat automatically. Instead, it’s a good idea to view them as an extra tool in addition to diet and exercise that can give you a helping hand when you hit a plateau or need to speed up your weight loss for an important occasion.
The key to helping your body burn fat and get the results you want is to use your supplement exactly as directed. Some supplements will require you to take several pills during the day, while others only need you to take one pill in the morning before breakfast. It’s always tempting to take more than you should in the hope that it will work faster, but unfortunately, weight loss pills work slowly, and taking too many won’t do anything other than cost you more money for no gain.
When Should You Consider Prescription Weight Loss Pills?
Some people struggle to lose weight even if their diet and exercise routine is on point. Taking a fat burning supplement may be enough to kickstart your body’s fat burning mode, but even that may not be enough to shift extremely stubborn fat.
If you’re still struggling to lose weight, you may benefit from prescription weight loss pills, especially if you’re putting yourself in danger with a massive calorie deficit (starvation diets, overexercising, etc.). It’s vital to speak to a doctor first, as they’ll be able to help diagnose any underlying issues or detect problems that may stop you from losing weight safely and effectively.
Some fat burners contain ingredients that interact with other medicines or may be unsuitable for pregnant or lactating women. We recommend talking to your physician before starting any diet or exercise routine or when considering a supplement. Your doctor will be able to evaluate whether a particular supplement is the best option for you and offer you alternatives to fat burners if necessary.
Many of us have unwanted belly fat, and fat burners are an appealing option to speed up the process of getting rid of stored fat. Unfortunately, finding the best fat burner can take more effort than sticking to your diet, especially as plenty of products with low-quality ingredients don’t even work.
We’ve taken a lot of the guesswork out of finding the right supplement. All of the fat burners on our list are from reputable manufacturers and contain scientifically-backed ingredients, such as green tea extract, glucomannan, and caffeine. If you’re looking for an added tool in your weight loss arsenal, these are great options to tackle unwanted belly fat and get your body beach-ready for the summer.
