Best Fat Burners For Men 2023 - We Break Down What Actually Works

The Top Mens Fat Burners Of 2023

At Center TRT we've spent a lot of time testing supplements that claim to be "fat burners", as the market has relatively low regulation in the US, there are a lot of products that simply aren't up to standard. Typically fat burners for men are aimed at not only assisting weight loss through a reduction in appetite, and an increase in resting metabolism, but also at improving workout performance and energy, helping you maintain muscle mass when in a caloric deficit. With that in mind we rate the best weight loss aids, aka the best fat burners, on the following criteria:

- Appetite Suppression
- Thermogenic Increase
- Energy Boost
- Customer Satisfaction
- Ingredient Quality
- Potential Side Effects
- Value

We also dislike proprietary blends, these mean we don't really know if you you're getting good value. And we won't recommend products that we haven't tested ourselves.

Our Top Picks For All Natural Mens Fat Burners 2023

Here at the TRT Center we take health seriously and 9 times out of 10 the absolute best thing you can do for your health if you're overweight is to lose fat. Mens fat burner supplements are no substitute for diet and exercise, and ultimately it is always going to come down to calories you take in vs the calories that you burn. But, these supplements can help increase your resting BMR (base metabolic rate - the number of calories you burn doing nothing) and suppress your appetite. And there's no skirting the issue, the average American man is obese. If you're reading this however, odds are you've either begun your weight loss journey or you've hit a plateau, either way, you're looking to shred fat.

Guys typically have different expectations of their weight loss aids than women. The majority of men will look to combine supplements with heavier exercise routines to help them maintain lean muscle mass, which becomes more difficult the higher their calorie deficit becomes. On top of this, men can typically tolerate more stimulants, and ingredients that cause bloating for females. The best fat burners for men take this into account and are designed to maximise the effects for men. Meaning that they are a fantastic tool to assist you on your fat loss journey.

All of the supplements that we recommend are produced in line with FDA guidelines and contain natural ingredients. And please keep in mind you should always take responsibility and as directed by the manufacturer. Weight management should be handled carefully and you should make sure to maintain a healthy BMI. Check our healthy weight chart for details. We've tested all the products below and rate them as the best fat burners for men in 2023.

What Do The Best Mens Fat Burners Do?

There's generally 4 main ways in which the top fat burners for men work, appetite suppression, thermogenesis, energy increase, craving suppression and fat cell binding in the digestive system. There's a couple of other specialised mens fat burning pills work, such as supporting keto diets with required nutrients that help breakdown fat, that the diet is low in for example.

Improve Thermogenesis

Fat burner supplements for men work in 4 ways, with different burners being better at different elements. Thermogenesis refers to raising your body's resting metabolism, and raising your temperature so you burn more calories whilst working out. It's generally the least effective element of any fat burning pill as it doesn't add a lot of calorie usage. But, even this can be helpful over a long period of time. Focus on this results in very high stimulant fat burning pills, as most of the effective ingredients are also stimulants, which have the added benefit of making you move more when not exercising raising your "NEET" and some overlap for suppressing appetite, like green coffee bean extract shown here.

Supress Appetite

One of the hardest things about trying to lose weight is being hungry. There really is only one way to combat this naturally, and that's by keeping your stomach full with things that have 0 or low calories. Many of the best fat burners for men contain Glucomannan as a result, which expands to 50x it's size, but there are other ingredients. Caffeine and Cayenne Pepper also have appetite suppressant effects as a result these make their way into a many fat burners.

Increase Energy

Not all male fat loss supplement options are full of stimulants, but a lot are quite heavy on caffeine and other stimulants, having more energy and moving more is not only going to help you burn fat, but improve lean muscle mass. If you opt for a stimulant free fat burner, that doesn't mean you won't get any increased energy as a lot of the top rated fat burners contain vitamins and minerals that will boost your energy levels even without stimulants. In most cases when men are looking to shred fat it's to get 6 pack abs and show off a toned physique, which they won't be able to do, if they're losing muscle from not hitting the gym due to calorie deficit driven lethargy.

Fat Binding

Some ingredients, such as green tea leaf extract have been shown to bind to fat lipids in the digestive system preventing your body from breaking them down. That's calories that won't absorb and thus wont become body fat. This means fatty foods will have a slightly reduced effect on your body composition by preventing fat absorption.

Mens Fat Burners FAQ

The most commonly asked questions about the best fat burners for men

Do Mens Fat Burning Supplements Work?

Well, the short answer is yes, the long answer is maybe. Firstly it depends on the fat burner, secondly it depends on what you mean by work. Is it a magic pill that's going to give you six pack abs without you making lifestyle changes, no. Is it something that can help supress appetite, maintain energy levels and thus your NEAT (we move less outside of scheduled exercise when we're hungry, this lowers our caloric burn through the day. A high quality fat burner for men will have a blend of ingredients designed to do this, and potentially raise your natural thermogenic calorie burn increasing your BMR (basic metabolic rate, or the amount of calories you use sat still). However, different blends are better for different things.

How Do Fat Burners Work?

Fat burners work in one of three ways, by supressing appetite, raisisng your energy levels, or thermogenesis (making your body run hotter and burning more calories). Generally speaking the most effective use of natural fat burners is the appetite supressant, followed by increased energy then thermogensis. For appetite supression, Gluccomannan is the best ingredient, as it expands 50X in the stomach, making even water feel filling, then stimulants such as caffeine are obviously effective. Move more, burn more calories. Lastly there's the thermogenic ingredients, whilst they do work, they provide the smallest percentage boosts to your weight loss journey, and also many of them have tenuous claims and are not very well understood. It's easy to see 3000mg of Glucomannan becomes the size of a bagel in your stomach (which could be 400kCal, without toppings) making you less hungry and how that would help you lose weight, and also that adding stimulants to the mix burns more calories as you move, but thermogensesis is where things can get complicated and lofty claims get made.

Are Fat Burners Safe?

The ones on this list yes, most natural fat burners, also yes. However, there are some perscription equivilants which do come with dramatic side effects. As for the natural fat burners on our best fat burners list, the worst that is likely to happen is you may have some mild stomach upset if an ingredient doesn't agree with you.

Do You Need Different Fat Burners For Men And Women

Short answer not entirely, but the long answer is yes. The best fat burner for men will not be what's best for women, and there's a simple reason for this, men have different needs when it comes to specific nutrients for the production of testosterone hormones, which aid fat loss and women tend to have more issues with bloating, and won't benefit from said ingredients. Womens fat burners also tend to have ingredients more designed to help curb cravings.

Should I Take Fat Burners For Men?

This is going to depend on a lot of things, firstly, what are you expecting them to do? If you're significantly overweight, then they're probably not the best place to start. We recommend that if your are going to use fat burning supplements then use them when you have reached a plateu. That way they will help you progress that bit futher. If you're looking to get an instant fix without a healthy diet and excersise then no, we don't recommend them as it will only be dissapointing.

Do Fat Burners Make You Sweat?

Some do, some don't those which are focused more on being thermogenic fat burners will probably make you sweat more. Whereas those which are desgined to suppress appetite shouldn't have those effects. If you're concerned about sweating we would recommend hourglass fit from this list as it's low stim and low

Do Fat Burning Supplements Work By Themselves?

The best fat burners for men are designed to assist with weight loss, making it easier to stick to your diet, train harder and give you a small amount of extra calorie burn whilst resting. So, they may do a little bit on their own, but for the most part you're still going to have to do the work, so keep this in mind when taking fat burners.

The Best Mens Fat Burner Supplement

Instant Knockout

Instant Knockout claims the number one spot in best fat burners for men list. And deservedly so, as it is, hands down the best fat burner on the market right now full stop. There's very little we don't like about it. It's a little bit more expensive than some options (but not by much). It's packed with glucomannan (in a large enough dose, unlike a lot of fat burners), which is the best appetite suppression ingredient currently available without a prescription[1].

Beyond that it ticks all the thermogenesis boxes with a healthy dosage of L-theanine, caffeine anhydrous and capsimax, going on to add to the caffeine energy boost with Vitamins B12 & B6. It also makes sure it covers some of the vitamins essential for fat burning that people struggle to get on reduced calorie diets, such as zinc and GTF chromium. This is essential because the only way to lose fat is to have more calories going out than coming in. Designed for top MMA fighters with legendary coach Greg Jackson, it was formulated to help fighters drop fat rapidly for weigh ins without losing muscle mass. As proven fat burners go, instant knockout has been through the ringer, and has been one of the industry's favourites for years. And with a recently improved formula, it's better at helping you lose weight and maintain muscle mass than before, although we do miss the bright red capsule, it did make the fist look a lot better in our review photos.

Why We Rate Instant Knockout As The Best Mens Fat Burner

Instant Knockout is what Mike and Jean (our resident gym rats) use, so it's no shock that we're going to give it our number one spot. They don't use it all year round and normally it's part of their January - February cut. Both swear by it's appetite suppressant effects. Boasting an impressive roster of ingredients, each of which having scientific studies backing its efficacy Instant Knockout takes our number one spot. It's had some recent formula tweaks, which have added more of the most effective ingredients to the mix. It's not just for athletic men though, Mike himself lost 50lb when he was overweight, so he wasn't always in shape, and swears instant knockout helped him, although he had already lost 30lb before he started using it, he said it helped him a lot with the last 20lbs. And yes, he did admit the reason he chose instant knockout originally was the cool fist shaped bottle. Being designed for MMA fighters, it's not really a surprise that it functions very well as a men’s fat burning supplement. The only downside to instant knockout's fat burning pill is that if you don't tolerate caffeine very well then it isn't for you. It's quite highly caffeinated, which is commonplace due to the thermogenic effects, energy boost and craving suppression that the well-known stimulant delivers.

Who Should Use Instant Knockout Cut

✔ Anyone looking to cut fat quickly
✔ People who have problems with snacking
✔ People wanting a supplement with the best fat burning ingredients
✔ Serious fitness enthusiasts looking for a solid no nonsense fat burner with tried and true ingredients

What's In Instant Knockout Fat Burners?

Instant Knockout contains Green Tea Extract, Cayenne Peppers, Glucomannan, Caffiene Anhydrous, Vitamin's B6 & B12, GTF Chromium, Zinc, Piperine and Green Coffee Bean. You can read more about the ingredients here. Many of these ingredients are in a lot of top mens fat burners, so the real difference when it comes to mid range fatburners and separating the good ones and the lower quality imitations is the volume of the ingredients. Which Instant Knockouts blend get's bang on. The Glucomannan is the star of the show in most of the fat burning supplements on our list, and we'll show you why below.

What's The Star Ingredient In The Best Weight Loss Supplements?

As you can see in our test to the left, we took two capsules from instant knockout cut them open, and placed them in a ramekin. We added water and left for about a minute. In this time the glucomannan (which swells to 50X it's original size) swelled to fill the ramekin, for context, we folded a bagel down into one the same size, which would be even smaller by the time it reaches your stomach. A bagel with cream cheese is around 400kcal, and on average, this would take less time to break down in your stomach than the fat burning supplements would. Meaning that you'd stay fuller for longer thanks to the supplement and 400 calories a day, is almost 1lb of fat a week. Other ingredients matter too, like the vitamins and minerals, but not many people know how Konjac Root works, and eating less will help you lose weight faster than any other effect from any of the fat burners for men listed.

Does Instant Knockout Work?

Short answer yes, it does, it certainly supresses appetite, there's no denying that, which is going to aid weight loss and it's natural ingredients have all been proven to raise metabolic performance.

The long answer is it's not a miracle in a pill. It's not going to make up for anyone eating far too many calories. But, it can give you the edge to help you shred fat that 10% faster. And if that matters to you, and it does to us. Then instant knockout works a treat, so if you're looking for you next best new fat burner, then we recommend instant knockout as the best value for money hands down.

Also recent changes to instant knockout mean we lose the iconic red capsules to be replaced with clear vegan friendly ones, sure the bottle doesn't look as cool, but removing the artifical colorant making it available to everyone is worth it as far as we're concerned. It's currently available from either roarambition.com or instantknockout.com

The Best Belly Fat burner For Men

Capsiplex Burn

Capsiplex Burn is another good fat burner. We’ve given it a trial, and the results are quite decent. While we would not recommend it above Instant Knockout, it is fair to say it works impressively, especially on belly fat. We can also assure you that it would work as a good pre-workout supplement for building lean muscles. Capsiplex Burn offers a wide range of ingredients in the right proportion. If you need a tested and trusted belly fat burner, Capsiplex Burn is not far off.

Check Capsiplex Deals

What's In Capsiplex?

Capsiplex contains a wide range of effective ingredients. This impressed us. We can see they got caffeine from Green Tea and Green Coffee extract, vitamins B3, B6, and B12, Potassium Iodide, Chromium Picolinate, L-Tyrosine, L-Arginine HCl, and black pepper, which is 95% Piperine.
However, the flagship ingredients we noticed in Capsiplex Burn are their patented cayenne pepper extract known as Capsimax and Innoslim, their patented ginseng and astragalus blend. Capsimax is a metabolism booster, fat liberator, and appetite annihilator. Innoslim also functions to burn fat, decrease calorie absorption from food, and redirect the few absorbed calories to help you build lean muscles.
We can ascertain that Capsimax, Innoslim, and other ingredients in Capsiplex Burn make a good mix. They are all important ingredients to burn fat, especially if you want to burn belly fat.

Who Should Use Capsiplex Burn?

✔Men who want to burn belly fat.
✔People who struggle to stay focused while training hard on a low-calorie diet.
✔Men, 18 and older, who want to lose fat fast to reveal the muscle underneath.

What Stands Out In Capsiplex Burn?

What we noticed in Capsiplex Burn is the low amount of vitamins B6 and B12 included. You can also see that it completely lacks vitamin D3 as well as glucomannan, the best appetite suppressor in weight loss supplements. However, besides this, it is a fairly rounded supplement overall. Innoslim, its patented ginseng and aspergillus blend, does a lot by decreasing the absorption of calories from food. Capsimax (cayenne pepper) also does its best to suppress appetite in glucomannan’s stead. If you want to burn belly fat and do not mind its few low points, Capsiplex Burn is a great pick.

Does Capsiplex Burn Work?

This is a yes from us. Capsiplex Burn absolutely works. However, you must note that Capsiplex Burn is not a magic pill.

You still need to exercise regularly and follow a strict, low-calorie diet.
Capsiplex Burn is tested and trusted, and we recommend it if you want to get your abs out for the summer.

It's definitely a good choice if you're looking for a thermogenic fat burner to support working out.

Caffeine Free Fat Burners For Men

Instant Knockout tops our best fat burners for men list, with Hunter Burn coming in second. Men generally tollerate high caffeine fat burning supplements better than women do, and at it's price point it does make it the best value. The question of which mens option you should choose is going to come down to if you're consuming a caffeinated pre workout and your budget. If you're already intaking a high volume of caffeine then go with hunter burn, however if you're not a coffee fiend then the best mens fat burner by dollar value is by far instant knockout.

The Best Premium Fat burners For Men

Hunter Burn

We've tested Hunter Burn a few times, and personally we had great results, but there wasn't quite enough difference for us personally recommend it over Instant Knockout. That doesn't mean that Hunter Burn isn't a great weight loss supplement. It is, and to be honest we quite like all of the hunter evolve range, they do seem to be geared towards having a softer effect on your stomach and promoting overall health. In short hunter offers a great range of supplements for men, even if they are a little expensive. But, if you're the sort of man who wants the very best, then hunter burn has the highest dosages of the strongest ingredients (excluding caffeine).

What's In Hunter Burn?

Hunter Burn includes a relatively small list of ingredients, but the ones it does use come with a price tag, they manage to avoid caffiene as used in cheaper supplement and the core list contains the following, D3, Konjac Root Extract, White Kidney Bean Extract, L-Theanine, Cayenne Pepper Extract and Matcha Gren Tea.

The most notable ingredients that marks Hunter Burn out as a premium fat burner for men is the Konjac Root and L - Theanine. Konjac Root is a particularly effective appetite supressent, helping prevent food cravings even in a calorie deficit, and the L Theanine amino acids help increase performance and can even help ward of illness. The product is also a lot friendlier when it comes to mixing it with pre workouts that contain caffiene.

Who Should Use Hunter Burn?

✔People who don't mind spending a bit more for a better product
✔People looking for a no caffiene fat burner
✔People who don't mind spending a bit more for a better product

What Stands Out In Hunter Burn?

The first thing you'll notice about Hunter Burn is the small ingredients list, what you may not notice is the high dosage of the most effective ingredients. The Konjac Root extract, or Glucomannan, is incredibly effective, but also quite pricey. D3 is always good and L Theanine is also quite interesting it has to be taken in more than 100mg to be effective (most cheap fat burners don't put enough in if they include it at all), but not only does it help burn fat and improve focus, it also helps aid sleep. Which if you're using more caffeine (to suppress appetite and for energy to help your weight loss journey) this is an ideal supplement for you.

Is Hunter Burn The Best Fat Burner For Sleep?

Arguably yes, we gave it the title of best premium fat burner, but you'll notice that we haven't listed a best fat burner for sleep or best night time fat burner, although if you've red this far, you can probably gather that this caffeine free fat burner, could well take that title as well. And for us it does, which is why we've not listed another with that title.

Typically speaking it's incredibly well received by the men who've reviewed it. And we've seen them touted as the best fat burning supplements for men over 30, which makes sense as getting older and having more issues with some of the harsher ingredients in other supplements would make hunter a better option for older guys.

Why Would I Choose Premium Mens Fat Burners?

If you want to make sure that you get the best ingredients, and if you're not tolerant of caffeine, which is in a lot of the mid range and cheaper fat burner supplements, then you may have to pay a little bit more, Hunter Burn is incredibly effective for appetite suppression so if that's your key sticking point this one is going to work wonders for you. If you're over 50 we would also recommend using a caffeine free fat burner, with ingredients that are gentler for your stomach, like Hunter Burn.

Animal Cuts - Best Fat Burner For Mens Bodybuilding

Animal Cuts is a great option, but if you don't like taking a lot of pills it isn't going to be for you. Nine pills a day to be exact. Due to the extreme volume of ingredients in animal cuts you can only take it for 3 weeks at a time, so we wouldn't recommend it for anyone who has a long way to go. But, it is great for a short term shred. For men looking to drop those last couple of pounds before an important day though it has got pretty much everything in it that could possibly help. It's very high on the caffeine and full of ingredients that cover other bases beyond simply stripping fat.

It's a good option for if you have a high tolerance for caffeine, but don't cope well with glucomannan. Missing glucomannan it loses some points on appetite suppression, but it does also contain a multitude of mood boosting ingredients like ashwagandha, which can be great when you're aiming for very low body fat percentages. This is really a supplement for body builders, not the average person. But, it's great at what it does.

There's a couple of bulking ingredients in here, that could've meant you wouldn't have to take quite so many pills to get the same effect which is a little disappointing.

Animal Cuts ingredients list is interesting, beyond fat burning ingredients, it even targets water stripping. Dandelion root which is a known diuretic[1]. This is effective for reducing bloating. Some people struggle with water retention more than others, so again this isn't a fat burner for every man, it's really designed for men with a single day in mind.

It contains a nootropic complex, which only becomes necessary when you're aiming for single digit body fat percentages, at this point most men struggle to focus as much and mood becomes lower.

We can't stress enough that Animal cuts is a short term mens fat burner, and should only be taken by men looking to shred for a competition or a week long vacation. Not, long term weight loss.

The metabolic complex in animal cuts is solid, it relies on a heavy blend of caffeinated ingredients, with various tea extracts, and coffee extracts. It already contains caffeine anhydrous which is an incredibly effective stimulant.

L-Tyrosine is used for craving management and Animal Cuts is pretty effective at this, which helps largely when you're down below 12% body fat. There's a host of other ingredients and you can read more about Animal Cuts in our full review.

Burn Lab Pro - Best Thermogenic Fat Burning Supplement

Burn Lab Pro is focused on the thermogenic element of fat burning. It's the only none budget weight loss supplement on our list that doesn't have glucomannan for appetite suppression.

Some men don't have problems with their appetite, but do want to burn slightly more calories in the gym. This is where Burn Lab becomes a good option. This highly specialised weight loss supplement is not something we'd recommend for most people, but is a good day to day alternative to animal stak.

Burn lab is a good product, but we don't think it's a good all rounder. So, if like most of us you struggle to feel full on a low calorie diet to cut body fat, then it shouldn't be your go to. However, if you're looking for a supplement that will help boost your metabolism, and you're already training hard at the gym and eating right then burn lab pro fat burning support is great.

HMB is a good and relatively unique ingredient for a thermogenic fat burner, and coleus foskohlii is OK. We'd have liked to have seen some caffeine in here for added thermogenic effect, but if you'd rather get caffeine from another source then again this could be a plus.

Chromium is a pretty standard pick, calcium is probably not something we'd have put in a thermogenic fat burner, but it never hurts for men to get some extra. It just doesn't really fit.

HMB is the most interesting element that's in here. It has been effective and was more effective at supporting body recomposition for men in trials. And this was also true for men who had been training longer. It's pretty common as a supplement in the bodybuilding community and for good reason. There's some evidence that HMB helps speed up fat oxidation in muscle cells improving your body's ability to convert it into energy over muscle tissue. Whilst it isn't going help boost metabolism by itself it could help you get more from your workouts, without simply raising body temperature like a lot of competitors, and as burn lab does that too, we've awarded them the title of the best thermogenic fat burners on our list. It does also appear to have some anti fatigue effects, so does double up it's efficacy in this regard.

Forslean is middling in it's effectiveness, in theory it helps promote creation of lipase enzymes used to break down fat, but unfortunately the evidence suggests it's only mildly effective. On a positive note however, it is by no stretch the main ingredient.

Capsimax makes it into most fat burning pills for men that are designed with thermogenesis in mind. It's been around for a while and is pretty well studied for it's ability to boost metabolism.

Burn lab pro will work best when taken over a longer period of time as it's increasing your calorie burn, which will always make a small difference than something which cuts appetite.

The Best Natural Fat Burners You Can Get

Breaking it down into our top 3 fat burners for men we have some clear winners with instant knockout being best overall fat burner, but also the best fat burner for men, animal cuts taking best for bodybuilding and hunter burn taking the spot of best premium fat burner for men.

We've tested all of them for a long time having used each one for at least a period of 90 days and with people who are used to taking fat burners. As such we can say we've been satisfied with the performance personally and that the science backs up the claims when it comes to the all natural ingredients.

Not Our Top Fat Burners For Men But Still Good

Why would I buy anything not in the top 3 fat burners? Well there are a few reasons, usually it's because a different fat burner will meet a specific need. Not all fat burners are perfect for the same thing, some can't be paired up with other supplements and some aren't suitable for other diets. One easy example, would be our best fat burner without caffeine, after all caffeine one of the most powerful appetite suppressants and metabolism raiser, as a result it makes it's way into a lot of fat burners, but if your daily diet already contains a lot of caffeinated drinks, or you have medication which means you can't take it, you could be looking for fat burners for men without caffeine? This is where our "other" categories come in.

Best fat Burner For People Who Don't Like Tablets

OxyShred - Non Stim

Not as good as hunter burn f you're looking for none stim fat burning supplements. And most people considering OxyShred are usually just looking for a caffiene free option, but where it really shines is for people who have difficulty swallowing pills, this may not seem like a huge market, but it's good that it's on the market. As men generally tolerate high stim consumption and konjac extracts very well, we don't recommend this unless you have issues with these ingredients. Whilst we wouldn't normally recommend a fat burner supplement that doesn't contain glucomannan, the fact is a powdered option can't contain the supplement as it would thicken the mixture far too much. So, even though it's not perfect, Oxy still makes for a useful if a little niche, stim free fat burner.

OxyShred Non-Stim contains all of the fat burning ingredients you would expect from a stimulant free fat burner, with the exclusion of caffiene, it contains Acetyl L-Carnitine, Raspberry Ketones and CLA, and Huperzine A this should not only help with fat burning, but it should also function as a nootropic, boosting focus and alertness in general which comes as an added bonus helping you lose weight and burn fat.

What We Think Over OxyShred Overall

OxyShred is an OK none stim burner overall, but the market for people who can't swallow pills is quite small, Raspberry Ketones are also typically more of a bulking product, and not one of the most effective options for a mans fat burner. Other than that we liked it and in it's particular sub category taste matters so we had to give it some extra points for that.

The main problem with powdered fat burners is going to be that they can't contain glucomannan, which is the most effective ingredient, in fact in some countries it's the only ingredient which you can legally claim to be an effective hunger suppressant.

Best budget High Stim fat burner

T5 Hardcore

This the very first fat burner Mike (our office expert on weight loss aids) ever tried, and it's definitely a solid contender, but it does fall short of our top 3, and it isn't really much cheaper, about a $10 difference. It works, but definitely is not as good of an appetite suppressant as Instant Knockout, which is where it falls short. That all said, the product is really well rated on amazon, with reviews typically having it sit around 4 - 5 stars. Realistically though, it's only going to give you an energy boost, which can be helpful when you're dieting to lose weight. Honestly, it's almost misleading to call it a fat burning supplement, it should be marketing as an energy booster or a specifically thermogenic fat burner for men.

What Is T5 Hardcore Fat Burner Missing?

So as we mentioned it could use a better appetite suppressant, that said, the better appetite supressants such as Glucomannan are usually only found in more expensive fat burners, which is why T5 is still a good budget burner. It does have Cayenne Pepper, which does have some appetite supressing effects, it just is by no means the best option. That said if curbing appetite isn't your primary concern and fatigue due to calorie restriction is more of an issue on your weight loss journey, then this fat burner then this is a good option. It's quite heavy on the green tea leaf extract and the green coffee beans so if you're not looking for a stimulant, then you should avoid this weight loss supplement.

But, we'd always recommend looking at instant knockout our best fat burner for men instead.

Best Keto Fat Burner

Keto Charge

Most fat burners are keto friendly, but Keto Charge is designed to supplement the Keto diet with vitamins that you'll people on Keto diets and is packed with "healthy salts" BHB Ketones, designed to get your body into ketosis faster and keep it there. Making this something of a unique offering, now, if you're not following a keto diet, this fat burner is pretty much pointless. But, if you are it's definitely worth a look.

What Makes Keto Charge Interesting?

In theory this fat burner is designed to keep the body in ketosis for longer, the exact blend is proprietary, which we don't like, this is why it didn't make it into the top 3 fat burners, despite all the positive reviews, but it's core ingredient is Beta-Hydroxybutyrate (BHB for short). BHB is a chemical produced in the body to help create energy when not enough carbohydrates or sugars have been eaten. This makes it particularly potent as an addition for people utilizing ketosis to burn fat as increased energy levels will reduce the likelihood of snacking and allow them to work out more intensely. Making Keto charge a great option as a Ketogenic Fat Burner for men.

What We Don't Like About Keto Charge

The only thing we don't like is that it's a proprietary blend, we don't expect any dangerous ingredients as the parent company is reputable, but it does mean we can't analyze it's value properly. There are however a lot of positive customer reviews and John our resident Keto dieter did rate his experience positively.

Best Money back Fat Burner

PhenQ

PhenQ is one of the most popular, if not the most popular fat burner on the market. It's also backed by a money back guarantee, giving it a unique selling point. That doesn't mean PhenQ is the best option out there, and honestly we don't really rate it that highly, but it does mean that you're not risking your money when you make the purchase, which definitely counts for something. And thus as one of the most popular it get's a mention on our list. Our problem is that it doesn't do much to reduce hunger, a key component in a good weight loss supplement.

If you are set on PhenQ, however, then you can find it here. But, we don't really recommend it. It's not exactly a great male fat burner, as it misses out on the most effective ingredients. Perhaps if you have a particularly delicate consitution, then it's passable. But, we'd recommend you pick one of the others from the list.

What we can say about PhenQ is that it does seem that they honor their money back guarantee, but the fact that they have too so often perhaps doesn't bode too well. PhenQ has a few unique fat burning ingredients, but they're mostly there so that Phen can claim to be different to the other dietary supplements and other fat burner supplements rather than them being more effective.

Dishonorable Mentions: The Fat Burners To Avoid

Anything illegal, anything banned, anything that costs less than $20 (usually an easy sign to spot a shoddy product). Other than that it typically depends on your needs, if you're looking for something to take in the evening then you'll want something that's designed to be a night time fat burner, which typically would be without caffiene like hunter burn, or if your female something that is less likely to cause bloating such as hourglass fit or leanbean. Any fat burner that claims you only have to take one pill a day, most of the ingredients are not effective at such low dosages and if they are, then they likely contain ingredients that may not be legal.

The Criteria For Our Best Fat Burners For Men List

Our best fat burners were ranked with the following criterea in mind, quality of ingredients, are the ingredients in large enough volumes to have impact.

How Do Mens Fat Burners Work?

Natural fat burners work by either helping to curb appetite, increasing thermogenesis, binding to fat sells to stop them being absorbed in the bodies digestive tracks, or addressing vitamin deficiencies that can result in unwanted fat storage and difficulties breaking down existing fat. The other common benefit of stimulants is that they encourage you to move more, even if this is in relatively subtle ways this typically results in an increase in calories used in a day.

Why Do I Have To Take Fat Burner Supplements So Often?

Unfortunately a lot of the ingredients are only effective in high dosages, for example Glucomannan needs to be consumed in over 1000mg a day to be effective, as it has to saturate your system. This is true across a lot of the ingredients. Fat burners that suggest lower dosages are normally not effective.

When is the Best Time To Take Fat Burners For Men?

Different fat burners are designed for different times of day, although the vast majority of the most effective fat burners do require you to take them multiple times per day. Our top best fat burner, instant knockout, does recommend you take it 4 times per day. Some fat burners are designed more for before sleep use, these will typically be low caffeine and not focus on appetite suppressing as you are unlikely to be eating in your sleep.

How Much Do Fat Burners Cost?

Fat burners tend to vary in price from as little as $19 to 100s of dollars, that said like all things you get what you pay for, at the low end you pretty much just get a caffeine pill, and at the high end you tend to get more high quality none caffeine related ingredients.

What Are Legal Fat Burners?

Legal or natural fat burner supplements are blends of minerals and vitamins utilized in the body to break down fat that are often underserved by western diets and lifestyles. As such these formulas do tend to have a positive effect for most people. The other core element is appetite suppression which is usually handled in cheaper fat burners with caffeine or other stimulants, whereas more expensive fat burners will tend to use compounds which bind to fat and stop it being absorbed into the body in the intestinal tract.

What Ingredients Are In The Best Fat Burners

Green Tea Extract

Green Tea Extract is a staple across most fat burners, it's not the most expensive ingredient and works well at binding fat in the stomach so it passes through the body rather than being absorbed into the body. One study found that catechins, which are the main nutrients in green tea, would boost fat oxidation up to 16% in just 24 hours[1] and a second proved that green tea extract is effective at assisting weight loss[2].

Cayenne Peppers

Cayenne Pepper seeds contain a compound called Capsaicin, this ingredient can be seen to reduce appetite, dramatically and also increase the bodies BMR (baseline metabolic rate) as is seen in this often cited study[3].

Vitamin D3

D3 has more of an impact on hormones than almost any other vitamin, not only is it proven to increase testosterone in men by up to 25%. It also boosts overall strength and increases production of lean muscle mass and is essential for maintaining healthy bone strength. The body can absorb vitamin D3 through sunlight, however, most people in the northern united states and Europe do not get nearly enough vitamin D3, leading some countries health boards such as the UK's NHS to recommend taking a D3 supplement all year round.

Caffeine Anhydrous

This dehydrated form of caffeine has been demonstrated to increase thermogenesis (fat storage usage) and improve performance whilst training. Using this overall review of thirteen randomized controlled trials, caffeine anhydrous definitively boosts energy and training performance as well as increasing metabolism.

Vitamin B6 & B12

Multiple scientific studies show that these two vitamins (B6 and B12) help reduce fatigue during exercise and stimulate fat loss when dieting, which is why they make their way into most pre workouts, and most weight loss supplements.

Glucomannan

Glucomannan is in most of the best fat burners, it's appetite supressent effects are incredibly potent in comparison to it's volume making it one of the must have ingredients for any premium fat burner. If it is not included in at least 1000mg dosages it is unlikely to have much effect, which is why our top 3 fat burners that use this ingredient have it in greater volumes. Whilst, you could argue it doesn't "burn fat" it's going to help you lose weight more effectively than anything else on fat burning ingredients list.

L-Theanine

It does need to be taken in more than 100mg to actually have any effect though, making it too expensive to include meaningfully in cheaper products. Ideally it should be included in quantities of 200mg as exampled in hunter burn.

Chromium

Chromium is more essential for men when it comes to burning fat, it helps aid hormonal regulation within the body and Testosterone plays a larger part in mens fat burners. It is still a beneficial nutrient for women, and helps burn fat deposits from unwanted areas when hormone production is causing storage aka stomach and thighs.

Black Pepper Extract

Black pepper extract or Peperine has been shown to block the formation of new fat cells, there have been relatively limited studies on this, but currently the results look very promising.
