Why Use A Fat Burner for Men
Men who want to burn their excess fat and lose weight often find it difficult to make the changes they want without losing muscle mass.
Although this is a problem that is particularly worrisome for men who do bodybuilding or sports, few men relish the idea of reductions in muscle size or strength.
Due to the need to follow low-energy diets, many men who are seeking weight loss experience reductions in vitality and become prone to midday energy slumps and fatigue.
Fatigue can make life miserable. It can also impair productivity at work or while doing sports and has the potential to ruin “family time” as well.
Fortunately, there are fat burners that can help men avoid all these problems and many of the best options can actually support improvements in muscle mass, making it easier for men to attain lean and toned physiques.
The best fat burners for men also help in other areas, such as controlling hunger. So, in addition to making weight loss more efficient, they make it easier as well.
But what are the best fat burners for men, and how do you find them?
We have researched all the most popular fat burning supplements men are using today and compiled a list of the most powerful options that provide the best value for money.
All the options are 100% natural. None of them have a reputation for causing side effects and customer reviews are excellent, right across the board.

PhenQ Ingredient Highlights
PhenQ thermogenic fat burner contains seven key ingredients and all of them have plenty of science behind them. However, in the interest of brevity, we are going to concentrate on a few of the most important ones.
The two most important fat-burning ingredients in PhenQ are a-Lacys Reset and Capsimax.
a-Lacys Reset is a proprietary ingredient that’s exclusive to PhenQ. It pairs the antioxidant alpha-lipoic acid (ALA) with the amino acid cysteine.
Even when it’s acting alone, ALA can accelerate fat loss. .
It also boosts energy by aiding the metabolism of carbohydrates.
Although cysteine has many virtues, it does not directly support weight loss. What it does do is support ALA’s ability to do so, greatly increasing its potency.
a-Lacys Reset is associated with very respectable improvements in fat loss. One of the best things about this little-used ingredient is it supports modest improvements in muscle mass as well.
Capsimax is a proprietary ingredient that harnesses the fat-burning capabilities of the capsaicin that’s naturally occurring in cayenne chili peppers.
Research is highly supportive of using capsaicin for fat loss. An in-depth evaluation of its abilities shows capsaicin increases metabolism, suppresses hunger, and provides other key weight loss benefits including activating brown adipose tissue (BAT). 
Like most of the best fat burners for men, PhenQ also provides a little caffeine. Although the dose is not overly high, it will enhance the energy-boosting capabilities of ALA.
Caffeine is also a proven fat burner supplement, so it’s an extremely useful inclusion. 
In addition to capsaicin, PhenQ also provides another powerful appetite suppressant. it’s called nopal and it comes from a cactus (Caralluma fimbriata).
Research show nopal extracts are good for decreasing hunger and helping decrease waist circumference. 
Where to Buy PhenQ Fat Burning Pills
You can only buy PhenQ from the manufacturer’s website. However, the manufacturer offers rapid free shipping along with plenty of discounts and special deals.
#2. C-Dine 501516 – Fat Burning SARM
<<CLICK to view C-Dine price and current special offers>>
Another natural fat burner that is not lacking in power, C-Dine 501516 is our no. 2 choice for men who are looking for a natural way to reduce and burn excess fat while maintaining muscle mass.
Although it’s a good option for any man who has fat to burn, C-Dine 501516 is a highly specialized product that’s primarily intended for bodybuilders. Especially those who are looking for a safe alternative to Cardarine.
Also known as GW501516, Cardarine is a performance-boosting fat burner that bodybuilders often include in their SARMs cutting stacks.
However, although Cardarine remains a popular option with many bodybuilders, animal testing suggests it may have the potential to cause organ cancers. Some bodybuilders may consider this an acceptable risk but plenty more do not so there has always been a big demand for safe and effective Cardarine alternatives.
C-Dine 501516 is part of a range of supplements produced by Crazy Bulk. The company has developed safe and effective alternatives to all the most popular bodybuilding drugs, including SARMs and steroids.
If you are a bodybuilder who needs a safe and effective supplement to help with fat burning and cutting, C-Dine 501516 is an excellent option. It will turn up your fat-burning potential while also improving your physical endurance and helping you to avoid loss of muscle mass.
If you only need a safe and effective fat burner supplement, C-Dine 501516 is an excellent option as well but PhenQ has more to offer because it will help you to avoid feeling hungry and stop your diet from getting you down.
Reasons to Choose C-Dine 501516 as Male Fat Burner Supplement
Obviously, if you are a bodybuilder who would otherwise be using Cardarine for cutting, C-Dine 501516 is the top option.
Other good reasons to choose this natural fat-burning supplement include:
- Improved endurance
- Extreme fat burning
- Rapid results
- Enhanced muscle definition
- Faster recovery between workouts
- Excellent customer reviews
- 60-Day Money-Back Guarantee
C-Dine 501516 Ingredient Highlights
C-Dine 501516 is quite a complex fat-burning supplement. It provides 11 key ingredients including vitamins, minerals, and plant extracts.
In common with PhenQ, C-Dine 501516 provides Capsimax, but the similarities end there. C-Dine 501516 is a very different type of fat-burning product that places as much emphasis on improving training capability as it does on burning fat.
However, in addition to being a high-potency fat burner, the capsaicin in Capsimax is also an appetite suppressant. So, although C-Dine 501516 will never be able to beat PhenQ when it comes to providing hunger control, it will still offer some level of support in this area. 
The formulation also provides some Vitamin C. Although it may seem like a strange inclusion, never sell this nutrient short. In addition to boosting immune function, Vitamin C can also help people who are aged 50+ to retain better muscle mass. 
C-Dine 501516 is a stimulant-free fat burner, many men may see that as a plus. However, although there is no caffeine present, the formulation contains B vitamins to boost energy levels instead.
B vitamins help the body extract energy from food. That’s why they are present in so many of the best brands of energy drinks.
C-Dine 501516 also contains Souther Ginseng and choline.
Southern ginseng (Gynostemma pentaphyllum) is a popular therapeutic herb that boasts capabilities that should help Crazy Bulk’s Cardarine alternative deliver efficient fat loss. 
Choline is an excellent addition as well. Research shows it can be very effective for delivering rapid fat loss without any reductions in physical strength. 
Where to Buy C-Dine 501516
C-Dine 501516 is exclusive to the Crazy Bulk website. However, the company allows you to get three bottles for the price of two and five bottles for the price of three. It also offers rapid free shipping as standard to customers all over the world.
#3. Prime Shred – Best Belly Fat Burner for Men – Vegan Friendly
<<CLICK to view Prime Shred price and current special offers>>
Prime Shred is another top-rated fat burner for men that ranks as one of the best fat burner supplements for men who like bodybuilding or sports.
If you have a hectic lifestyle, Prime Shred may be particularly attractive because you only need to take one dose per day. Simply take three capsules at breakfast and that’s it. Job done. Your body will be primed for faster calorie expenditure throughout the day.
However, although most men should be able to use Prime Shred fat burner and attain excellent results, as with many of the top options, to get the best results you will need to commit to a strict healthy diet and get plenty of exercise.
Reasons to Choose Prime Shred to Burn Body Fat Percentage
Prime Shred is one of the best options for men who need a fat burner that will help them to do the following things:
- Break through plateaus
- Burn pure fat
- Get rid of fat in stubborn areas such as belly fat
- Transform their bodies
- Get leaner and more ripped than ever before
In addition to being a powerful weight loss supplement, Prime Shred is also the belly fat burner with the best guarantee. It lasts for 100 days.
Prime Shred Ingredient Highlights
The Prime Shred fat-burning formulation provides 12 ingredients. It’s a mix of nutrients, amino acids, and high-potency botanical extracts.
Although Prime shred has a modest amount of caffeine, it contains several B vitamins as well. This makes it one of the best fat burners for men who love to train and are seeking plenty of extra energy to help them to do it.
As with the previous two fat burners, Prime Shred’s potency as a fat burner is partly attributable to capsaicin. As we pointed out earlier, it’s a versatile natural compound that boosts metabolism and helps control hunger as well. 
Prime Shred also provides green tea leaf extract. Like capsaicin, green tea has excellent credentials as a fat burner. The metabolism boost it provides can last a long time. Often up to 24 hours a day. 
Prime Shred provides green coffee bean extract as well, along with a decent dose of Rhodiola rosea.
Green coffee bean extract provides chlorogenic acid. Research shows this compound can be very useful for reducing stubborn fat and reducing waist circumference. 
Rhodiola rosea is an adaptogen herb. It’s unlikely to increase weight loss but it’s very good for reducing anxiety and stress. Research suggests Rhodiola rosea may also offer protection from burnout.
Prime Shred is the only top-ranking fat burner for men that provides this ingredient and its presence helps make this supplement one of the best options for men who like to push themselves extra hard in the gym. 
Where to Buy Prime Shred Natural Fat Burner Supplements
Prime Shred is another premium fat burner that’s only available via the official website. However, as with most of the other top options, shipping is always free and the site offers some cracking money-saving deals.
#4. Instant Knockout Cut – Pre Workout Natural Fat Burner
<<CLICK to view Instant Knockout price and current special offers>>
Instant Knockout Cut is an all-natural weight loss supplement that used to be only available to professional fighters but is now available to all.
As with a lot of the top fat burner pills for men, Instant Knockout Cut is heavily geared towards improving workout capacity and has tremendous potential both as a fat burner and as a pre-workout.
Unfortunately, if you choose this fat burning pill, you will need to take four doses per day. However, with plenty of caffeine and B vitamins locked inside each capsule, Instant Knockout is a great option for men who often find themselves running out of steam during the day.
Reasons to Choose Instant Knockout Cut
Instant Knockout Cut provides the following benefits:
- Hunger suppression and suppress appetite
- Enhanced fat-burning capabilities
- Fat metabolism
- Extra energy throughout the day
- Improvements in physical stamina and training ability
Instant Knockout Cut Ingredient Highlights
Although Instant Knockout Cut has excellent credentials as an energy booster and appetite suppressant, its fat-burning capabilities are greater still.
The formulation contains three of the most powerful natural fat burners⸺cayenne, green tea extract, and green coffee bean extract. [2, 8, 9]
Instant Knockout Cut’s fat-burning processes are further supported by the presence of caffeine, which also contributes much to the supplement’s energy-boosting effect. However, caffeine does not need to go it alone in this regard because the formulation contains some B vitamins as well.
Instant Knockout Cut also has an ingredient we have not covered before because it is not present in any of the other best fat burners for men. It’s called glucomannan and it’s one of the most respected natural appetite suppressants in the world.
Glucomannan is a high-fiber ingredient that’s milled from the roots of the Asian konjac plant. It’s incredibly absorbent and can soak up 50 times its weight in water.
When glucomannan hydrates, it expands considerably, filling the stomach. This increases satiety, dulling the desire for food. 
Where to Buy Instant Knockout Cut
Instant Knockout Cut is another thermogenic fat burner supplement that is only available directly from the manufacturer.
Free shipping is offered to customers in the USA and UK, but you have to order two bottles or more to get it.
When you order three bottles, the offer of free shipping becomes worldwide. Unfortunately, there are no discounts to be had or any special deals. Nor is there a money-back guarantee.
These things are a little disappointing but customer reviews suggest the results Instant Knockout Cut provides are not and it remains the go-to fat-burning supplement with many top-ranking professional fighters and trainers.
#5. Clenbutrol – Cutting Steroid Alternative
<<CLICK to view Clenbutrol price and current special offers>>
Clenbutrol has much in common with C-Dine 501516. Both weight loss supplements are manufactured by Crazy Bulk and are primarily aimed at bodybuilders who are seeking safe alternatives to fat-burning drugs.
Clenbutrol is the Crazy Bulk substitute for Clenbuterol. Did you spot the difference? The drug has the letter “e” before the final three letters. The Crazy Bulk alternative does not.
Often stacked with cutting steroids, Clenbuterol is possibly a little safer than Cardarine because it has no links with organ damage or cancers.
However, Clenbuterol can cause a lot of other unpleasant side effects including heart palpitations, muscle cramps, weak bones, and cardiac hypertrophy.
Some bodybuilders have been hospitalized due to using this drug, Crazy Bulk Clenbutrol is a far better alternative.
Reasons to Choose Clenbutrol as a Male Thermogenic Fat Burner
Definitely choose this fat burner instead if you were previously considering using Clenbuterol.
Other reasons to choose it include:
- Powerful fat burner for men
- Improves physical performance
- Great as a pre-workout
- Supports lean muscle mass
- Excellent Customer reviews
- 60-Day Money-Back Guarantee
Clenbutrol Ingredient Highlights
If you choose to use Crazy Bulk Clenbuterol for fat burning, you need to take three capsules per day, pre-workout. Like the drug it replaces, Crazy Bulk’s supplement is both a fat burner and a performance enhancer.
Each dose provides four key ingredients. One of them is vitamin B3, to help provide energy.
Clenbutrol also provides guarana extract and bitter orange.
Guarana is a fruit that’s high in caffeine. However, it’s a slow-acting stimulant that rereleases its caffeine content slowly. This reduces the risk of side effects while also prolonging the benefits.
Bitter orange is a citrus fruit. It provides the stimulant synephrine, which is good for increasing energy and also has excellent credentials as a fat burner. Research suggests it works particularly well when used in conjunction with exercise. 
Clenbutrol is intended to be used pre-workout. That makes bitter orange a particularly well-chosen inclusion.
The final ingredient is garcinia cambogia. It’s a fruit extract too. Another excellent inclusion, garcinia cambogia provides hydroxycitric acid (HCA).
HCA is a versatile compound that controls hunger while also helping the body to burn visceral fat (belly fat) more efficiently. [13, 14]
Where to Buy Clenbutrol
As with all Crazy Bulk supplements, you can only buy Clenbutrol via the official company website. Shipping is free (worldwide) and, if you want to get extra bang for the buck, it’s possible to get three bottles for the price of two or five bottles for the price of three.
No matter how big or small your order, your purchase will be protected by Crazy Bulk’s standard 60-day money-back guarantee.

How Do Fat Burners Speed Up Weight Loss?
Fat burners accelerate fat loss in several ways. The main thing they do is boost metabolism. More often than not, they do this by increasing thermogenesis. Supplements that work in this way are sometimes marketed as thermogenic fat burners. However, this is not always the case.
Most of the best fat burners for men contain extracts taken from green tea and/or cayenne. Both options increase thermogenesis yet many of the top options are not marketed as thermogenic fat burners. However, the manufacturers often mention their supplements’ ability to increase thermogenesis.
Thermogenesis is the process responsible for generating heat within the body. Exercise increases it, causing the body to lose extra energy as heat. Thermogenic fat burners such as red chili pepper capsaicin and green tea catechins cause the body to lose extra energy in this way too.
Many of the best fat burners for men also provide appetite suppressants. These make fat loss less unpleasant by reducing or removing the discomfort of hunger.
Without hunger to weaken will and determination, it becomes easier to stick to the kind of low-energy diet that forces the body to begin burning its fat.
Good fat burners also fight fatigue. That’s another welcome bonus when you are following a low-calorie lifestyle. PhenQ goes a bit further by suppressing fat cell creation and enhancing mood.
Factors to Consider Before Buying Burner Supplements for Men
Here are some things to consider before buying male thermogenic fat burner supplements.
Before you use any brand of supplement, you need to know what is inside and what the ingredients can do⸺good and bad.
Some natural ingredients, such as cayenne pepper extract and green tea have plenty of scientific research to back up their abilities. All of the supplements we recommend on this page, contain credible ingredients such as these.
However, many manufacturers fail to disclose all the ingredients they are using and/or hide the inclusion rates. If you do not know what is in a supplement or how much, it’s best to avoid it.
Even when supplements use credible ingredients like green tea leaf extract, black pepper extract and caffeine, results will not be forthcoming if they do not provide enough.
Unfortunately, in the case of caffeine, many supplement manufacturers use too much. They do this because it is such a cheap ingredient to use. This type of tactic can produce supplements that produce short-term weight loss but are equally good at causing jitters, nausea, and other unpleasant side effects.
It’s also best to avoid fat burners that contain lots of unnecessary binders, fillers, or other useless ingredients. Their presence adds no value and may interfere with the abilities of the key ingredients.
None of the premium fat burners that made our top 5 contain unnecessary binders or fillers. If they did, they would never have earned a place on our list.
If you choose any of the men’s fat burners we recommend on this page, side effects and other undesirable issues should not be a concern.
However, if you decide to throw caution to the wind and go it alone, avoid fat-burning supplements that contain banned or dangerous ingredients such as ephedra, DNP, and DMAA.
Fat Burner for Men Customer Reviews
Customer reviews are also important. They provide you with an idea about the kind of results to expect from men’s fat burning pills. If lots of people have plenty of good things to say, that’s great.
However, if they are complaining about side effects, poor customer service, billing issues, or scams, that’s very informative too. It’s a sign you need to be looking elsewhere.
Men’s Fat Burner Price
You will not be able to buy any of the best fat burners for men and pay Dime Store prices. It would be great if you could, but it’s not how things are. It’s important to retain realistic expectations.
There may be products that fit into that price bracket but they are more likely to deliver disappointment than to help you to burn fat and lose weight.
However, paying over the odds does not guarantee an effective product either. It’s very easy to pay £100 or more per month and end up with a fat burner that does nothing at all.
Even if you do not take advantage of special savings and discounts, it’s possible to buy any of the top fat-burning supplements we reccomend and pay around $50-$80 per month.
Where finances permit, we strongly suggest taking advantage of special deals that provide discounts and/or extra bottles of pills.
Most men who are seeking fat burners and weight loss support have long journeys ahead of them. It’s not sensible to pay the full price month after month when so many of the top manufacturers offer better ways to do it.
How Do Fat Burners Work?
Fat burners, also known as thermogenics or fat oxidizers, are dietary supplements used to increase energy and reduce body fat. Commonly used ingredients include caffeine, synephrine, capsaicin and forskolin.
Each of these components activate thermogenesis – the process of producing heat in the body. This increases core body temperature and metabolism to burn more calories throughout the day. Additionally, some have appetite-suppressant qualities which help manage cravings and control unhealthy snacking.
When taken together in correct doses, these ingredients can helpto move fat cells from storage into the bloodstream where it is used for energy instead of being deposited on the body as fat.
Therefore utilizing a quality fat burning supplement can be effective in helping men and women reach their weight loss goals by increasing their metabolism, decreasing appetite and ultimately helping to lose fat.
Best Fat Burner for Men Summary
Burning fat and losing weight can be a challenging task. It can be even harder for men who are concerned about losing muscle.
However, there is a solution for every problem under the sun and, in this case, we have found not just one but five.
Of course, depending on your personal level of fitness and body goals, certain options may be more appealing than others.
As we said at the beginning of this guide to male fat burners, PhenQ stands out as being the best weight loss pill for most men requiring help to lose weight and reduce stored fat.
The other four options are for men with more specialist fat-burning and training needs. Instant Knockout Cut is a good example. If you are a keen participant in any of the fighting sports, it’s probably going to be the best option to choose.
In all cases, the best fat burners are the ones that provide men with support in all the specific areas they need it the most.
