Written by Isaac Robertson

When some folks hear “fat burner,” they reject the notion outright.

Others have the opposite reaction and think of them as a kind of miracle ​pill that is going to generate weight loss while they eat pizza and watch the game.

The truth about fat burners, at least the top ones, lies somewhere in the middle. They’re neither a hoax nor a miracle.

What they can and will do is help you get the most from your weight loss efforts by increasing your metabolism, decreasing your appetite and attacking the fat stores you’ve so carefully constructed by eating all those pizzas.

Below are the top fat burners for men on the market today based on our detailed research.

1. Editor's Choice:​​​​ Instant Knockout

Instant Knockout is produced by Roar Ambition and generates its fat burning effects by raising your metabolism 24 hours a day, not just when you’re working out.

Ever wonder why skinny people are skinny? It’s not because they don’t eat. Many of them eat like pigs. It’s because they have a naturally fast metabolism.

It seeks to replicate that through its use of metabolism boosting ingredients including caffeine and glucomannan along with green coffee bean extract, zinc, vitamins B6 and B12, and more.

The bottom line is that Instant Knockout won’t allow food to linger in your system and turn into fat stores.

Roar Ambition claims that during the first few weeks of use, as long as you continue to exercise and eat well, too, you’ll find some noticeable changes in your body you probably didn't see before. This is why a lot of people, including us consider it as the best fat burner for men.

PROS

  • Helps stimulates the metabolism.
  • Reduces food cravings.
  • ​Promotes thermogenesis.
  • ​Enhances your amount of available energy.

CONS

  • ​The gelatin capsules won’t agree with vegans.

​2. PhenQ Weight Loss Pills

There are a lot of snake oil type weight loss pills out there, and I’m always suspicious when I see new ones pop up.​

But, when I saw results achieved by a few friends of mine using PhenQ, I had to dig deeper.

Basically, the company focuses a lot on having created a unique blend of ingredients that you would normally only achieve by stacking multiple supplements. As a result, you get a number of benefits from one product at a lower price.

Having looked at hundreds of online reviews, I noticed that fat loss and appetite suppression were some of the strong points that users point to.

PhenQ
Best Price GreenBTN

Combine this with a healthy diet and some regular exercising, and you are likely to notice a difference in your appearance.

PROS

  • ​Helps to boost fat burning metabolism to target stored body fat
  • ​Good appetite suppression reported by users
  • Helps reduce fat storage process
  • Helps boost physical and mental energy

CONS

  • ​Only available as pills not in powder form

​3. CrazyBulk Clenbutrol

You’ll probably struggle to find a gym these days where you don’t see someone taking some sort of a CrazyBulk product. 

The company really has made a name for itself, and this Clenbutrol supplement is a very good example.

According to the creators, the ingredients chosen have been scientifically proven to boost thermogenic processes in your body.

That fancy term basically means that your body will turn up the heat a little and in doing this will burn stored body fat.

It’s not a magic pill that will allow you to eat donuts all day and sit on the couch. But looking at user reviews, I did notice indications that it works well with daily exercise.

CrazyBulk Clenbutrol

​As long your overall diet and exercise routine is healthy, you will see a faster weight loss progress. It’s also a good option for bodybuilders during a cutting cycle.

PROS

  • Natural ingredients create a safe and legal product
  • Helps boosts thermogenic processes to burn more fat
  • Helps boost energy levels throughout the day
  • ​Gluten-free and no artificial additives.

CONS

  • ​Requires taking 3 capsules per day

4. BURN-XT

Burn XT takes a 3-pronged approach, unlike some of the other fat burners on the market that we would recommend.

The company that made it seeks to help boost energy levels, increase your metabolic rate and suppress your appetite. Does it work?

For the most part, it would be "yes." I could feel a noticeable boost in energy an hour after taking Burn XT.

And after eating, we did not seem to stay physically full as long as before, which is a sign your body is metabolizing food faster.

Perhaps the one area where we weren't bowled over was appetite suppression, because we still were visited by hunger pangs and a desire to carb up from time to time. But then again, the decision to resist those pangs are still entirely up to you.

PROS

  • A reliable thermogenic fat burner.
  • ​No hinky ingredients hidden away.
  • ​No artificial preservatives, flavors or dyes.
  • ​Full money-back guarantee if not satisfied.

​CONS

  • ​There were times when we felt a bit jittery.

5. Vintage Burn

The makers of Vintage Burn are concerned that in some cases, ​pills like this can also be muscle burners.

The fact is, however, that most of the times when a person loses both fat and muscle it’s because they’re not exercising.

They’re just bombarding their system with these high quality fat burner supplements that also consume muscle tissue unless you do something (like exercise) to fend them off.

That said, the quest to create a pill that won’t touch your muscle tissue as well is a noble one.

Green Button

To do so, Vintage Burn utilizes two ingredients you don't find in most other products: raspberry ketones and chrysin. Raspberry ketones metabolize fat stores unlike anything else, and chrysin works effectively to preserve your muscle and help you retain an elevated metabolic rate, even while at rest.

PROS

  • May probably be the best fat burner for men.
  • Contains raspberry ketones.
  • Improves alertness and elevates mood.
  • More affordable than some alternatives.

​CONS

  • Contains a fair amount of caffeine.

6. Simply Health

Simply Health hits most of the right notes in its quest to be taken seriously as a world-class supplement.

The makers of this fat burner have done their homework -- and that's evident by the ingredient list that includes L-carnitine, garcinia cambogia, conjugated linolenic acid, and more.

All these ingredients work to either help raise your metabolic rate or attack stores or both and is said to have ample scientific evidence behind them to support their claims of effectiveness.

Simply Health is produced in an FDA certified facility that is regularly inspected to ensure it conforms to the exacting guidelines laid out by the Good Manufacturing Practices code.

Simply Health
Green Button

This is said to be a product of high purity that also happens to be reliable and easy to use.

PROS

  • ​Targets belly fat.
  • Helps increase metabolic rate.
  • ​Stymies appetite.
  • ​Made in the USA under strict guidelines.

​CONS

  • ​Claims of appetite suppression may be exaggerated.

7. Evlution Nutrition Trans4orm

Evlution’s Trans4orm has a very straightforward approach to calorie and fat burning:

​Stimulation.

It's an approach that has been proven effective for decades, but it's not one without risks that a more well-rounded approach can help you avoid.

That's not to say that Trans4orm is dangerous.

Just that its heavy reliance on synephrine and caffeine could be problematic for some folks; leaving them feeling a bit jittery and perhaps interfering with their ability to get to sleep.

Green Button

That said, perhaps if you put all the extra energy Trans4orm is going to supply you in your workouts, you’ll likely be able to get to sleep just fine.

The problems arise when you don’t exercise and are essentially lying around with lots of static energy coursing through your body.

So, get up and make sure you work it off.

PROS

  • Helps increase energy as advertised.
  • ​A valuable aid in the gym.
  • Helps improve focus and mental acuity.

​CONS

  • ​Failing to workout is not a good idea.

​What Is a Fat Burner?

fat burning pills

​It is any drug or, for the purposes of this list, a ​pill that purports to assist your body in burning fat it would otherwise store.​[1]​​​

These are most effectively employed as part of an overall diet and exercise regime aimed at losing weight and building muscle.

Over the years there have been many types on the market, including so-called “diet pills” that were little more than straight amphetamines and were prone to be abused.

Natural fat burning supplements like the ones profiled above are a much safer yet equally effective way to reduce weight without risking addiction or other odious health issues.

​The term 'fat burner' is used to describe nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure, impair fat absorption, increase weight loss, increase fat oxidation during exercise, or somehow cause long-term adaptations that promote fat metabolism.

​How Does ​It Work?

There are three main approaches to fat and calorie burning.

Some employ them all while others focus on just one or two. Those approaches are:

  • ​Appetite Suppression - Appetite suppression is an important tool in the fat ​burners, and there are two principal ways it's accomplished. The first is by working to increase production of the hormones serotonin and dopamine while the second - and far more popular - is to simply fool your stomach into feeling full. The​ products above all take this latter approach.

  • ​Preventing Fat Absorption - The right combination of natural ingredients can help your digestive system metabolize fat as energy rather than storing it away for that rainy day that never comes. Raspberry ketones are an excellent example of this.
  • Speeds up metabolism - Most fat burners today does this in one way or another. Some use caffeine, while some use a variety of other ingredients like L-carnitine, garcinia cambogia and more. The goal is to make faster, more effective use of the food you eat.

We have a full-depth guide that explains all of this as well as whether or not do fat burners work? You can also watch the video below which also explains how these fat loss pills work in the body.

​​Factors to Consider ​Before Buying Fat Burning Pills

Each is different, but in general you'll want to look for these things in your fat ​burners.

  • Proven ingredients - You’ll want to see some or all of these on the ingredient list: green tea extract, caffeine, yohimbine, cayenne pepper, black pepper extract, green coffee bean extract, and more including raspberry ketones and Garcinia Cambogia.
  • ​Amount of caffeine - Make no mistake, caffeine is the most effective natural stimulant ever discovered and can undoubtedly help you burn more fat. The thing with caffeine is that it works so good it’s easy to use too much and lie awake all night. Check the caffeine content.
nutrition facts
  • ​The brand - Some companies have been producing high-quality ​fat burners for years while others have only recently appeared on the scene and don't have a proven record to back them up. Do your research on little-known brands before deciding to use them.
  • ​Overall value - Some fat burners are going to cost substantially more than others, so if you're on a budget, you'll want to keep that in mind. There are some out there that are both effective and affordable, such as Instant Knockout.

​​Natural ​Ingredients For ​Weight Loss

natural fat and calorie burners

​It is important to know some of the natural weight loss agents that can be found in your fat ​burner. Here are some of those ingredients:

  • ​Caffeine - Caffeine is the grandaddy of fat burners that stimulates the metabolism while lighting a fire under your energy levels. Oldest and still the best.
  • Green tea extract - is known to boost the metabolism and prevent fat absorption. It won't give you a kick like caffeine, but it will go to work on your body.
  • Protein powder - A diet that is high in protein and low in carbs has been shown to be great at burning fat. Just be sure to look for balance in this type of diet.
  • ​Soluble fiber - Soluble fiber helps curb your appetite by combining with water in the digestive tract and making you feel fuller than you are. When you eat less your body seeks energy from fat, and you lose weight.
  • Yohimbine - Yohimbine blocks the body's alpha 2 adrenergic receptors thereby freeing up adrenaline stores and providing you an energy boost. The more energy you exert, the more fat you'll burn.

​Are There Potential Side Effects?

There are a lot of myths and rumors swirling around about these ​fat burners. The fact is that the vast majority are perfectly safe and produce no side effects in most of the people who take them.

​But that's not to say they are entirely risk-free; rather, the risks have just been blown out of proportion in some circles.

​Fat burners are basically safe although you should be aware of the following:

  • ​Those with weak or compromised cardiovascular systems may put undue stress on their heart by consuming some of the stimulants used in fat burning products. While these people are the exception, the risk cannot simply be swept under the rug. Consult your doctor before using this type of product just to be sure.
  • ​Some folks will experience mood swings, and, if too much caffeine is taken with no exercise program to help burn off the excess energy, they may become more aggressive than they typically are. Avoid this by making sure you exercise.

  • ​Some people have allergic reactions to certain ingredients. If you have any doubts about whether the ingredients in a particular ​supplement are right for you, consult your doctor before taking them.
  • Finally, some people complain that certain stimulants used to kickstart the metabolism give them an upset stomach. Caffeine will certainly do this to some folks with sensitive systems. If it happens to you, the best advice is to try a different products that doesn’t rely so heavily on caffeine. There are plenty out there.
