For a man, there is nothing worse than belly fat. Well, maybe annoying people at the gym who take up bench press units texting. That might be worse, but belly fat is pretty bad. Hopefully, my list of the best fat burner supplements for men can serve as a little light at the end of the pudgy tummy.
A fat burner alone might not get rid of excess fat. However, if you combine one of these top notch fat burners with a relatively healthy diet and some exercise, you can certainly make things a heck of a lot easier. The below fat burners, in my humble and expert opinion as a Nutrition & Wellness Consultant (NWC), are the top options in the fat burner supplement industry.

What are the best fat burners? Here’s our top 10 list:
We used our unique Supplement Facts Panel (SFP) analysis formula developed by our certified Nutrition & Wellness consultant in order to come up with what we believe to be the best fat burner supplements on the market. When it comes to fat burning, it simply does not get any better than the top three options on this list.
1. Prime Shred (best fat burner overall)
Prime Shred is the new top dog in the natural fat burner space for a lot of reasons, the most important of which is that it tops the charts in terms of overall potency at nearly 2,000 milligrams per serving. There are 10 active ingredients including Green Tea Extract, Green Coffee Bean, DMAE, Cayenne Pepper, and more.
The balance of thermogenic ingredients, stimulants, and metabolism boosters makes for a very effective and all-encompassing approach to burning fat. When it comes to weight loss, the key is to decrease calorie intake and increase calorie expenditure…well, the Prime Shred formula does exactly that.
Prime Shred is best for:
- Metabolism boost
- Energy boost
- Increased focus
- Burning more calories
- Improving exercise performance
- Decreasing cravings
2. Instant Knockout (best for appetite suppression)
Instant Knockout is without question the most powerful fat burner on the market due to its extremely high potency, excellent ingredient selection, and multi-faceted approach to weight loss. Most fat burners are one dimensional and accomplish one goal, but not this one…
First of all, it provides over 1,500 milligrams worth of active fat burning nutrients per serving, which is the highest number in the industry. The 10 active ingredients include metabolism boosters, appetite suppressors, and energy boosters such as Green Coffee Bean extract. These are the three key components of fat burning, and Instant Knockout thoroughly addresses each one.
In order to burn fat and lose weight, your calorie expenditure must be greater than your calorie intake. So, in other words, you have to burn more calories than you consume. Instant Knockout is designed to both increase calorie expenditure AND decrease calorie intake, which is why we love it so much.
With 500 MG of Green Tea Extract (known to boost metabolism due to high EGCG levels) per serving, you can be confident it will help boost metabolism and ultimately calorie expenditure. On the flipped side, it also contains 500 MG of Glucomannan per serving, which is a very powerful and highly fibrous appetite suppressant. Therefore, it helps you feel less hungry less often, which means your calorie intake decreases.
Instant Knockout is best for:
- Boosting metabolism
- Reducing calorie intake
- Burning stubborn fat
- Inducing thermogenesis
- Suppressing appetite and cravings
3. PhenGold (best for thermogenic benefits)
PhenGold was an easy choice for our second best fat burner because of the amount of clinical data supporting the theory that the formula can produce results. On their website, they show clinical studies and testimonials backing their ingredients and formula as a whole.
The formula is very impressive and highly potent. PhenGold has an exceptionally high overall potency of about 1,600 milligrams per serving and contains 6 active fat burning ingredients including Green Tea, Green Coffee, Cayenne Pepper, and L-Tyrosine.
We also found that PhenGold has received a lot of positive customer reviews and user feedback, which can be important to take into account. The Supplement Facts Panel is highly impressive, user reviews are great, and the website presents clinical evidence of the supplement’s effects regarding its ability to reduce body fat. What more can you ask for?
PhenGold is best for:
- Increasing energy levels
- Burning stubborn fat
- Improving metabolism
- Reducing cravings
- Thermogenic effects
4. CCut (best for bodybuilding benefits)
CCut was designed to function as a natural alternative to the illegal anabolic steroid called Clenbuterol. The steroid Clenbuterol is use by bodybuilders to help them cut weight and achieve a slimmer, more ripped physique as opposed to a bigger, bulkier physique.
Brutal Force, the makers of CCut, set out with the goal of creating a safer, healthier alternative that could produce those same bodybuilding benefits. Obviously, this supplement is not going to be as effective as an actual anabolic steroid. Hopefully that goes without saying.
However, the formula is pretty powerful, and we think they did a great job here. You get about 1,200 milligrams of nutrients in every serving, which is a very high potency level. It only contains three active fat burning ingredients, but all three are very high quality nutrients that have been shown to help produce fat loss, being Garcinia Cambogia, Bitter Orange Extract, and Guarana Extract.
CCut is best for:
- Could help build lean muscle
- Enhancing exercise performance
- Inducing thermogenic benefits
5. Physique Series (best for men who are already fit)
The Physique Series fat burner was created by Transparent Labs, who is a pretty well known USA based company in the sports nutrition space. However, this fat burner is more designed for fit guys who already exercise daily and are just looking for an extra boost. We don’t see it as being great for out-of-shape guys who need to burn fat quickly.
With all that being said, let’s talk about the formula. With nutrients like Forslean, Green Tea Extract, and Cayenne Pepper, this is one of the more comprehensive formulas we’ve seen in the fat burner market place. Cayenne Pepper specifically is one of the strongest thermogenic nutrients out there.
Physique Series is a very well rounded and thoughtfully formulated thermogenic fat burner, but we don’t see it as being able to compete with the top three due to the fact that it lacks a couple of key nutrients and is not quite as potent as the top shelf options.
Physique Series is best for:
- Fit men
- Guys who lift weights regularly
- Helping induce thermogenesis
- Boosting athletic performance
6. Trans4orm (best for BCAAs)
Trans4orm made it onto this list despite its low overall potency because of its formula transparency and high quality ingredients. These weight loss pills contain proven fat burners such as Green Tea and L-Tyrosine in pretty high dosages, those being 500 MG and 200 MG respectively. That’s pretty impressive…
The problem is, the dosages really start to drop off and get much smaller from that point forward in this formula, which ultimately leads to an overall potency of just over 1,000 MG per serving. This is still solid, but at the end of the day, the fact is Trans4orm is 50% less potent than our top ranked best fat burner.
We simply can’t recommend this weight loss supplement as highly due to its comparative lack of potency and sort of one dimensional formula. It’s just not as comprehensive or powerful as our top choices.
Trans4orm is best for:
- High amino acid dosages
- Elevating energy levels
- Enhancing athletic performance
7. Shred Matrix (best for convenience)
Shred Matrix is a very solid Muscle Pharm fat burning supplement that would be higher up on this list if it didn’t use one giant proprietary blend. We love seeing that the overall potency per serving is as high as it is, but we need to see individual dosage sizes. It’s a big problem that all of the dosage sizes are hidden inside of this giant proprietary blend…it means we don’t know exactly what we are getting here.
Shred Matrix had a real shot at one of the top spots on this list, but a proprietary blend the size of this one is just too significant of a problem. We can’t comfortably recommend a supplement unless we know exactly what’s in it, and the blend prevents us from being able to know that.
Shred Matrix is best for:
- Fat burners that can be bought at GNC
- High stimulant dosages
- Significant amount of caffeine for boosting energy
8. Cellucor Super HD (best for energy boosting)
Cellucor Super HD just barely made it into this list. Would we classify it as one of the best fat burners overall? No, but the formula is solid enough that it earned one of the last spots on our list. The biggest issues here are proprietary blend use and lack of overall potency, but aside from that, Cellucor has a pretty decent formula here…
Super HD has Caffeine Anhydrous, L-Tyrosine, and a great blend of B Vitamins. The dosages of some ingredients are disclosed, which is good…we just wish ALL dosages were disclosed. Also, it packs under 1,000 MG per serving, which is pretty weak.
Due to the low overall potency and lack of transparency with many of the ingredient dosages, we don’t see this fat burning supplement as being able to compete with the elite fat burners that are ranked more highly on this list. It’s just not quite at that top notch level.
Cellucor Super HD is best for:
- Beginners who prefer a mild formula
- People who don’t mind proprietary blends
- Boosting energy levels
- High stim formula
9. Shred Jym (best for L-Carnitine supplementation)
Shred Jym was created by the ultra popular company Jym Supplement Science, which is what initially brought it onto our radar. This supplement is a brand new addition to our best fat burners list and has the chance to work its way up into a higher spot, but for right now based on what we see, a bottom spot on the list is where we feel it belongs.
Shred Jym has a pretty high overall potency, but the problem is that 1,500 of the 2,000+ milligrams are just one ingredient: Acetyl-L-Carnitine. This is a great ingredient, but we would like to see the potency spread throughout the formula instead of so ultra concentrated in one spot.
Due to the supplement being too dependent on one single ingredient, we don’t feel comfortable recommending Shred Jym very highly on this list.
Shred Jym is best for:
- Believers in L-Carnitine
- High BCAA dosages
- Exercise performance enhancement
10. Vintage Burn (best for ketogenic dieters)
Vintage Burn is a decent option for people on the ketogenic diet because of the fact that it contains raspberry ketones, which can help if you are trying to get into ketosis. It’s not going to get the job done on it’s own, but it can certainly provide a little extra help.
Outside of that, the formula also contains Garcinia Cambogia, Green Tea Leaf, and Green Coffee Bean. These are all high quality ingredients that can increase metabolism and calorie expenditure, but a couple of the dosages are low.
The biggest problem with Vintage Burn is that it’s missing appetite suppressants, which as we mentioned before, are the key to decreasing calorie intake. Vintage Burn is missing too many key ingredients to be ranked any higher on this list.
Vintage Burn is best for:
- Increasing metabolism
- High Garcinia Cambogia dosage
- High levels of caffeine
What’s the top thermogenic fat burner on the market 2022? Our conclusion
Instant Knockout easily takes the top spot as the most effective fat burner supplement due to its high concentration of appetite suppressants, large dosages of metabolism boosters, and all around multidimensional approach to weight loss.
There is just no other supplement like it. No other fat burner supplement contains 500 milligrams of appetite suppressants, and no other fat burner has such an equally balanced focus on decreasing calorie intake while increasing calorie expenditure, which is the most effective weight management strategy.
It is the most potent formula and the most well rounded formula, and the transparency and lack of a proprietary blend is much appreciated. It’s not often you get that kind of transparency in sports nutrition.
FAQs on thermogenics/fat burners
Are fat burners safe?
While you should always consult your doctor, fat burners are generally safe for most people since they only contain natural ingredients. Thermogenics are natural, and none of the supplements on this list contain any “red flag” ingredients.
Do fat burners burn muscle?
No, fat burners don’t burn muscle as long as they utilize the correct ingredients. Illegal anabolic steroids tend to burn muscle, and so do prescription drugs. However, natural fat burners typically do not have that side effect. They usually help you lose fat without reducing muscle mass.
Do fat burners upset your stomach?
Fat burners typically do not cause upset stomach. If you have a particularly sensitive stomach, then you may experience discomfort due to the appetite suppressants, but most people don’t notice.
Do thermogenic fat burners work?
Yes, thermogenic fat burners have worked for a lot of people. The process of thermogenesis significantly increases the number of calories you burn throughout the day, which has helped many people burn fat.
