How do fat burners work?

Thermogenics are the main type of fat burners on the market. These work by increasing your metabolic rate – all that means is that you are using more calories throughout the day. Even when you’re sat watching TV or on the computer, your body will be using more energy/calories than normal. This is an easy and effective way for bodybuilders and athletes to get leaner, quicker.

Suppressing your appetite – some of the more advanced fat burners on the market have been formulated to help you reduce your food cravings by making you feel full, this is very useful when you’re dieting and eating clean. Anyone that has been on a diet for a long period of time will know how hard it is to avoid eating high-calorie foods, especially after you’ve had a hard workout.

By raising your metabolic rate and helping to reduce the amount that you eat, your body starts becoming a fat-burning machine. This is why fat burners are effective and help you to lose those extra few pounds of stubborn body fat.


What to look out for with a good fat burner?

Every supplement company seems to have a fat burner, some have two or three, all claiming to do the same thing – get you ripped in no time.

Try looking past the hyped up claims and drill straight down to the ingredients – that’s what’s going to do the job for you.

We’ve looked at tons of studies and found that the most effective and safe ingredients available are the natural ones:

Caffeine – Boosts Energy so you are more active and burn more calories

Green tea – This ingredient has many benefits in the body including fat burning. This study shows that green tea increases the rate that the body breaks down fat and increases the utilization of glucose.

Chilli peppers – Particularly Cayenne peppers that contain capsaicinoids which promote weight loss through increased metabolism and this study found that it also reduces appetite.

B vitamins – This important vitamin is helpful when it comes to boosting metabolism and helps convert food into energy.

Glucomannan – This fiber from the konjac plant expands in the stomach and makes you feel fuller for longer so you eat less and have fewer cravings.

Green coffee extract – This extract is one of the best fat burning ingredients. It comes from unroasted coffee beans which are rich in Chlorogenic Acid. In this study, Chlorogenic-Acid was able to inhibit fat absorption and increase fat metabolism in the liver.

Forskolin – This ingredient has been shown to increase the release of fatty acids and this study showed forskolin was able to decrease fat and increase lean body mass in obese people.

Ingredients to Avoid

Fat burners have a bit of a bad rep, a lot of men avoid them because they think they’re dangerous or will give them lots of unwanted side-effects. This is true with some of them, in the past companies have used unsafe ingredients in high amounts, they can raise the heart rate too much, give you a headache, jitters etc. We advise avoiding the following ingredients:

2,4-Dinitrophenol / DNP
1,3 dimethylamylamine / DMAA

Yohimbine and Bitter orange / Synephrine are other ingredients to be careful of, they can be OK in small amounts.

If you have any heart, liver, kidney problems or any serious medical conditions we recommend staying away from fat burners. Always consult your doctor if you are unsure.

Proprietary Blends

Generally, we recommend staying away from supplements that hide their formula in a proprietary blend. This is even more important with a supplement that contains stimulants, you need to know how much you will be taking each day.


Best 5 Fat Burners for Men

We’ve spent a lot of time researching the ingredients, company’s reputation and reading the customer reviews on the best fat burners for men available right now. Here’s the rundown:


1. Instant KnockoutBest Fat Burner

This gets our top spot because it’s been formulated using the latest research, contains the most amount of proven ingredients and has excellent customer reviews. With its name, fist-shaped bottle and red capsules, Instant Knockout is a badass product. Out of all the supplements that we have ever bought and tested, this one by far looks and feels the most premium.

Instant Knockout offers you the ability to:

  • Erase stubborn fat
  • Boost energy levels – train harder (even on a cut)
  • Beat nagging hunger
  • Achieve noticeable results in weeks
  • Avoid side effects with an all-natural formula

How does Instant Knockout work?

The website says it was originally formulated for MMA fighters and boxers to help them get cut up and ripped in time for a fight. It’s literally been created to help you get fighting-fit.

The fat burner is designed to have a thermogenic effect on your body. In other words, it boosts your metabolism. It does this by heating up your body, which then forces it to burn more calories to return to normal temperature. And burning more calories means faster weight- or fat-loss.

Instant Knockout also features a proven appetite suppressant to help you beat nagging hunger – especially useful when you’re on a cut.


Instant Knockout contains nine all-natural and well-researched ingredients. It contains Caffeine, but in a lower dose than most other sports-based fat burners we’ve seen. As a result, it’s unlikely to cause the anxiety that can result from taking too much of the stimulant.

The lack of synthetic or harmful ingredients also means you’ll pass a drugs test if you use to cut before a sporting event.

How to take Instant Knockout

Always stick to the manufacturer’s directions for use. In this case, Roar Ambition (the manufacturer) says you must take 1 capsule with a glass of water, 4 times a day.

In fact, this fat burner’s directions are unusually specific – a sure sign the manufacturer knows what’s it’s doing.

Take your first capsule “immediately after waking up” and your second “between breakfast and lunch”. Then take your third capsule an hour after lunch and your fourth (and final) capsule one hour before dinner.


What brought this product to our attention is the ingredients. It contains our top natural ingredients in the right amounts. These include:

Green Tea Extract: Contains catechins – bioactive polyphenols which raise your total energy burn, lift your metabolism and help you burn fat faster.

Green Coffee Extract: Gives you a healthy dose of chlorogenic acid, which is thought to reduce sugar cravings (a prime cause of hunger) to help prevent overeating. It’s also thought to lower cholesterol and improve users’ body composition.

Cayenne Pepper: Packed with capsaicin – a spicy compound which has a thermogenic effect on your body. In other words, it speeds up the rate at which your body processes food into energy and stops it being stored as fat.

Caffeine: A popular stimulant, Caffeine inhibits the adenosine receptors to make you feel more alert. Caffeine can replace the energy you lose when cutting calories.

Glucomannan: Extracted from a plant root, Glucomannan is a dietary fiber that swells up in your stomach to help you feel full and suppress your appetite. This makes dieting a lot easier and helps to stop those sugar and fat cravings in between meals.

Any negatives?

You can only buy it online direct from; you won’t find it on Amazon, GNC, eBay or any supplements shops. At $59, it’s a premium-priced product, so it may not fit your budget.

Instant Knockout also uses gelatin capsules, which means it isn’t suitable for vegans or vegetarians.

What do other people say about Instant Knockout?

Lukas used Instant Knockout to transform his body in just 3 months:

Travis says Instant Knockout is the “no brainer choice” when it comes to fat burners:


Based on the ingredient profile and customer reviews, we strongly recommend Instant Knockout as the best fat burner for men. The combination of the natural stimulants and a proven appetite suppressant make this a perfect product for anyone looking to cut fat safely.

2. Hunter Burn

Hunter burn fat burner

Next, we have another premium fat burner that’s pretty new to the market, but that is already making waves for its sheer effectiveness. Hunter Burn is made by Roar Ambition and is geared toward older guys looking to burn fat and lose weight. However, it can really be used by men of any age. The reviews for Hunter Burn are excellent – and after looking at it closely, we can see why.

Here are some of the benefits of using Hunter Burn:

  • Lose the belly, but not the muscle
  • Stick to your diet more easily
  • Avoid anxiety and energy crashes
  • Maintain the energy to perform at your best
  • Raise your confidence

How does Hunter Burn work?

Each bottle of Hunter Burn contains 180 capsules, which equals a serving size of 6 capsules per day. This amounts to larger dosages and a more powerful formula that is designed to get real results.

Hunter Burn contains at least one ingredient that is shown to help users burn fat AND build/maintain muscle.

But Hunter Burn isn’t just a fat burner. It also contains an appetite suppressant to help you beat cravings, as well as a carb blocker to help stop you putting on weight when you do eat too much.

How should you take Hunter Burn?

According to the manufacturer’s directions, you should swallow 2 capsules with a glass of water, 3 times per day – and you must take each dose half an hour before each of your three main meals.


This “premium” fat burner also uses a cleaner, safer formula. In addition to using the best-quality forms of its 6 all-natural ingredients, Hunter Burn is also free from artificial colors, flavors and preservatives, as well as gluten, soy and GMO.

Unlike most fat burners, Hunter Burners doesn’t contain any harsh stimulants. As a result, it won’t make you feel anxious or jittery.


Hunter Burn’s formula uses 6 proven ingredients all in very generous doses. Let’s take a look at some of the main ingredients:

Vitamin D3: An unusual addition to a fat burner, D3 is more often seen in testosterone boosters. Using it in Hunter Burn may be a genius move – research shows the nutrient helps users maintain and build muscle, as well as cut fat.

Konjac Root Extract: One of the few appetite suppressants recognized by the FDA, Konjac Root is also known as Glucomannan. This ingredient expands in the stomach, so you feel fuller for longer. This leads to you eating less and consuming fewer calories throughout the day. The 3000mg dose of this ingredient certainly delivers.

Green Tea Extract: A popular fat burner ingredient proven to increase metabolism so you burn fat faster than you normally would. Hunter Burn uses Matcha Green Tea – a more sought-after form of the nutrient which is 3 times stronger than the more common types.

Cayenne Pepper: Shown to increase your metabolism through thermogenesis. It has also been shown to reduce your appetite – and this is why it’s one of our favorite ingredients.

White Kidney Bean: Whereas Konjac can help you beat hunger, White Kidney Bean is a carbohydrate blocker which gives you a ‘pass’ on those occasions when you do eat too much.

Any negatives?

The biggest negative with this product is going to be the price. At $75 for a bottle, it certainly deserves its “premium” moniker. That said, there are savings to be made if you buy in bulk.

This product is also only available through the manufacturer’s website. You won’t find it in stores or anywhere else on the internet.


Overall, this is a really nice fat burner with strong, natural and effective ingredients. The use of 2 appetite suppressing ingredients will definitely have you eating less. And when you add in faster metabolism, it’s clear Hunter Burn is one of the most powerful fat burners we’ve seen. It is on the more expensive side, but if you don’t mind spending the extra money, it is well worth it. Check out Hunter Burn review here.

3. PhysiqueSeries Fat Burner and Stim-Free Fat Burner


Best Fat Burner


Next up we have another really nice fat burner from Transparent Labs. This one is a bit cheaper than our first products but is still very effective so it could be a good choice for people looking to save a few bucks.

This is another one that has some really good ingredients and some really nice reviews. We also really like that this one has a stimulant free version as well for guys who may not like stimulants or may not be able to handle them very well.

There are no proprietary blends, fillers or artificial with this fat burner. This one is as the company name says, transparent.

Transparent Labs covered all the bases and made a really nice product that easily comes in second place.


This fat burner features 500mg of forskolin as one of its main fat burning ingredients. Forskolin has been shown to reduce body fat while maintaining muscle. It is getting a lot of buzz right now as a newer and better fat burning ingredient and it is living up to all the hype.

On top of that, it also contains some of our other favorite stimulants – Green Tea, Cayenne Pepper, and Caffeine. These work together to naturally increase your metabolism for faster fat burning.

The stim-free version uses Acetyl L-Carnitine which also increases fat metabolism and is a non-stimulant.

This product also has a nice dose of 5-HTP to reduce appetite and keep those cravings down.

Any negatives?

Only available online
Premium priced, but worth it.


PhysiqueSeries Fat Burner and Stim-Free Fat Burner is a really nice, natural formula. It has mostly positive reviews out there and is a cheaper alternative to Instant Knockout or Hunter Burn. If you are looking for a stimulant free fat burner this would be your best choice.

4. SPORT Fat Burner by Performance Labs

SPORT Fat Burner by Performance labs

Next up we have a newer product with SPORT Fat Burner by Performance Labs. It is another really nice product for you to think about.

This product is designed to stimulate fat-dissolving enzymes and fat-burning hormones and also increase your energy levels so you burn more calories throughout the day. On top of that Sport Fat Burner is designed to help you preserve that hard-earned muscle in the process. Long story short, the fat goes and the muscle stays. Let’s take a look at what they put into it:


Like all Performance Lab products, their Fat Burner is natural, clean and safe to use daily.

It’s been designed for performance, not cheating. So you won’t find any stimulants or caffeine. The capsules are vegan-friendly and prebiotic-infused for easy digestion.

The proven combo of Cayenne and Black Pepper will have you burning through calories. Without sending your heart rate and blood pressure sky high.

A 250 mg dose of Coleus Forskohlii will help with natural thermogenesis. Plus, it triggers some very handy enzymes that will encourage your body to unbind fats. Maximizing lean muscle.

But the star of this show is the 1000 mg of Beta-hydroxy beta-methylbutyrate. HMB is a real multi-tasker of muscle-friendly bioactivities, helping you to:

  • Build bigger and stronger muscles – thanks to super-efficient protein synthesis and increased oxygen consumption.
  • Train harder for longer – by delaying the build-up of lactic acid.
  • Burn fat as fuel – rather than losing precious muscle mass
  • Neutralize damaging enzymes that are produced by high-intensity training.

So if you’re cutting calories – or even fasting – in combination with training, but don’t want to lose bulk. You’ve found your brand.

They also do a complimentary Whole Food Multivitamin that we recommend stacking with your Fat Burner. That way you won’t miss out on vital nutrients on your shredding mission.

Any negatives?

Performance Lab® don’t sell via Amazon, so you’ll have to go to their website. But they ship worldwide and their customer service is top-notch. Quality like this doesn’t come cheap though. They are one of the more expensive on the market.


Quality product from a quality company. All-natural and safe to use every day. And you can also put Performance Lab® SPORT Fat Burner to the test without risking a penny. If you’re not 100% satisfied with the results after 30 days, they’ll refund your money. You literally have nothing to lose.



5. SuperHD Xtreme by Cellucor

best fat burners for men

SuperHD Xtreme is made to work on 4 levels including mood, energy, definition, and focus. It’s made by Cellucor and it is their top of the line fat burner they make. They also have 5 other fat burners in their line-up but this one is the best of the bunch.


This one has a big dose of caffeine with a 300mg dose per pill. It also features their patented Teacor which is a stimulant that studies have shown people do not build a tolerance to like caffeine and other stimulants. They also put in some Cayenne extract in here and a few other things but it looks to be mainly a fat burner based mainly on stimulants. If you have a type of sensitivity to stimulants you should probably avoid this one.

Any Negatives?

This one may be too many stimulants for some people and it is also a bit on the pricey side.


While this one does have pretty good reviews SuperHD Xtreme is definitely not the best value on the list. If you like stimulants and you don’t mind spending money this one could work for you but I would spend my money more wisely.
