9 Best Fat Burners for Men 
There is no escaping the fact that losing weight can be a slow and challenging process. You need to exercise regularly and watch what you eat and drink. You may even need to give up some of your favorite foods. There may also be times where you feel tired, moody, or hungry.
The good news is that fat burners can help you lose weight more quickly and easily. But which are the best fat burners for men?
There are hundreds of different fat burners around, and some are more effective than others. Some of these popular supplements are nothing more than caffeine pills. In contrast, others contain exotic herbs and other ingredients that calm your appetite and increase your metabolism, making any diet much easier to stick to.
To help you choose the right fat burner, we’ve tried, tested, and reviewed eight of the best. Each of these products can help you lose weight quicker and easier, but only when combined with a healthy diet and regular exercise program.

- Proven, tested ingredients
- Vegan-approved formulation
- Boosts mental and physical energy
- Not suitable for users with caffeine sensitivities
- Only available online
With 145mg of caffeine per serving, Phen Gold is a high-stim fat burner that should not be used after 3-5 pm as it could stop you sleeping. However, it’s proven formulation will speed up fat loss. This is a top-rated, well-reviewed product.
Alpha Lion Shredder is a potent fat burner, pre-workout energizer, and appetite suppressant designed to make losing weight quicker and easier. Packed with tried-and-tested, scientifically proven ingredients, this well-formulated product attacks stored body fat on several different fronts at once.
- Scientifically proven, high-stim formula
- All-day energy matrix to beat fatigue and improve vitality
- Fat burning matrix to increase metabolism
- X-factor matrix to decrease hunger and increase insulin sensitivity
With 300mg of caffeine per serving, you’ll definitely feel this product working. Not only will it crank your metabolism up to the max, it’ll also boost your energy so that you can work out harder and longer than usual. This will accelerate the fat loss process even more.
- Easy to use
- Powerful formula
- Proven ingredients
- Increases energy while boosting fat burning and decreasing hunger
- May contain too much caffeine for some users
- Quite expensive
- A 90-capsule container will only last 15 days if you take the recommended six capsules per day
While no fat burner will work unless you eat right and exercise, the powerful ingredients in Alpha Lion Shredder will multiply your efforts, so you lose weight and burn fat faster than ever before. The high caffeine content may be a problem for some users, but any side effects can be avoided by using less than the recommended six capsules per day.
If you want a fat burner you can really feel working, Instant Knockout is the one for you. Loaded with 300mg of caffeine per serving, this product will boost your energy and focus for faster fat burning and great workouts.

- Powerful, proven formula
- High energy ingredients
- Ideal for exercisers
- Suppresses hunger while accelerating fat loss
- 300 mg of caffeine may cause unwanted side effects in some users
Instant Knockout is part fat burner and part pre-workout energizer. If you take this product much after 5 pm, it’ll probably keep you awake all night too! If you are okay with such a high-stim fat burner, this product will definitely help you lose weight faster.
Clenbutrol is not the same as clenbuterol – a drug used by bodybuilders to burn fat and build muscle. However, this product does contain active, safe, natural, fat-burning ingredients that can help you lose weight.
- Vitamin B3 for enhanced fat burning
- Garcinia cambogia for less new fat cell formation
- Bitter orange extract for increased metabolic rate and thermogenesis
- Guarana extract to boost energy and fight fatigue
This is an excellent product that contains several proven fat-burning ingredients. However, marketing it as a clenbuterol alternative is very misleading as there is nothing in its formulation to support these claims. That’s a shame because, inaccurate marketing strategies aside, this product should still help you burn fat and lose weight.
- Powerful, proven formulation
- Modest caffeine content
- Designed to boost focus, energy and fat burning, while suppressing appetite
- Very misleadingly named product
- Contains gelatin so not suitable for vegetarians or vegans
Clenbutrol should not be confused with clenbuterol, but that doesn’t mean it’s not a good fat burner for men. This fat burner is safe and legal to use, but the same cannot be said for similarly named clenbuterol.
Burn XT is another high-stim fat burner designed with men in mind. This well-formulated product contains the same amount of caffeine as two large cups of coffee, so you’ll definitely feel it working. It’s ideal for dieters looking for more mental and physical energy.
- Acetyl-l-carnitine for increased fat burning and more energy
- Green tea leaf extract for its thermogenic properties
- Anhydrous caffeine for energy, focus, and fat burning
- Cayenne pepper extract for increased thermogenesis
- Bioperine to increase the effectiveness of the other ingredients
Thermogenic supplements increase your temperature, which, in turn, speeds up fat burning. In simple terms, thermogenics turn up your fat-burning thermostat. Burn XT contains two thermogenic agents to ensure you burn fat as fast as possible.
- Powerful formulation
- Boosts mental and physical energy
- Suitable for vegetarians and vegans
- Budget-friendly price
- 275 mg of caffeine per serving may cause unwanted side effects in some users
This high-caffeine fat burner is ideal for people who want a product that has a noticeable effect on energy and focus. It may be too intense for some, but as high-stim fat burners go, this one is very good.

- Green tree extract for energy and fat burning
- Green coffee bean extract for increased thermogenesis
- Caffeine anhydrous for energy, focus, and fat burning
- Raspberry ketones for energy
- Garcinia cambogia to prevent the formation of new fat cells
This doctor-formulated fat burner contains a lot of proven ingredients. And, yet, despite having been formulated by a world-regarded nutritional expert, it contains clinically unproven raspberry ketones and a proprietary blend, which means it’s impossible to know how much of each ingredient you are consuming. This fat burner definitely works, but more label clarity would have been useful. For example, this product contains caffeine, but it is unclear how much.
- Good range of ingredients
- Fast-acting formulation
- Suitable for vegetarians and vegans
- Well-priced product
- Proprietary blend means quantities are not known
- Contains unspecified amounts of caffeine
While this product really does work, it’s hard to say exactly why because the amount of each ingredient is not known. It does contain caffeine, and it’s a safe bet to say it’s at least 100 mg per serving, but it may be more. If you are okay with caffeine, then this product should produce great results. However, if you are sensitive to the effects of caffeine, you may want to avoid this product as it might contain more than you are comfortable taking.
Key Information about Fat Burners for Men
Fat burners can definitely help you lose weight faster and easier. But, before you use these powerful supplements, make sure you consider the following essential information.
How to get the most out of fat burners
Fat burners are very effective supplements, but you’ll get more from them if you use them properly. You can’t just pop a few capsules and expect to start losing weight! Get the most from your chosen product by using it correctly.
- Follow the manufacturer’s instructions – each formulation is different, so make sure you check the guidelines and follow them. This includes any information on timing as well as how many capsules you need to take.
- Start off with the smallest recommended dose – taking too much too soon could cause unwanted side effects. If you are given a range to use, start at the low end and increase gradually and according to your tolerance.
- Do not exceed the recommended daily maximum – when it comes to fat burners, more is not always better. In most cases, exceeding the maximum recommended dose won’t help you lose weight faster, but will make any side effects worse.
- Combine fat burners with a sensible diet and exercise program – as effective as fat burners can be, they aren’t magic bullets. They support healthy weight loss and only work if you work too. Think of fat burners as effort multipliers; the harder you try, the better their effect will be.
- Don’t take fat burners for prolonged periods – fat burners work best when used for relatively short periods, such as 2-3 months. If you use a fat burner for longer than this, you may become accustomed to the ingredients, and they may cease being effective. If you need to use a fat burner for a long time, swap formulations from time to time to avoid developing a tolerance.
Potential side effects
Fat burners usually contain natural, proven, safe ingredients. However, because they affect your metabolism and energy levels, they may also have some unwanted side effects. Those side effects include:
- Stomach upsets
- Loose stools
- Increased urination
In most cases, the main ingredient responsible for any side effects is caffeine. Some fat burners contain way more caffeine than a large, strong coffee. If you have a caffeine sensitivity, you may find that your chosen fat burner comes with some unwanted side effects. If caffeine causes problems, choose a stim-free fat burner. These products increase your metabolism without caffeine and usually have far fewer side effects.
Ingredients to look for and ingredients to avoid
Fat burners contain lots of different ingredients. Some are herbs and spices, while others are vitamins, minerals, or amino acids. The best ingredients to look for in fat burners are natural as they usually have the least number of unwanted side effects.
It’s impractical to list all the ingredients used in fat burners. Still, some of the best choices include green tea extract, L-carnitine, L-tyrosine, CLA, green coffee bean extract, curcumin, ginger, cinnamon, ashwagandha root extract, niacin, chromium picolinate, and glucomannan.
Harmful or useless ingredients you should try and avoid include:
Ephedrine – a once-popular thermogenic, ephedrine, and its close relative ephedra, have been banned by the FDA because of their dangerous side effects.
Raspberry ketones – unlike real BHB ketones, raspberry ketones won’t increase fat burning, boost your energy, or speed up your metabolism. They are not the same ketones your body produces during a low-carb keto diet.
Naringin – extracted from grapefruit, naringin may help you lose weight, but we don’t really know how this substance works. It’s only effective for a few people too. Naringin probably won’t do you any harm, but it’s not a proven fat burner.
Hordenine – chemically similar to bitter orange extract, hordenine is often used in place of this proven fat fighter. There is very little evidence to support the effectiveness of this compound. Seek out real bitter orange extract instead, an ingredient supported by science.
DHEA – this naturally occurring hormone may help you burn fat and build muscle. Still, it comes with a lot of side effects, such as increased testosterone production. Most men should avoid manipulating their hormone levels as doing so can lead to serious medical problems.
Fat burners for men make weight loss easier. They don’t work miracles, but, combined with a sensible diet and exercise program, they can help you get a better weight loss return for your time and energy.
Some fat burners make sticking to your diet easier, by beating hunger and providing you with a much-needed psychological boost. Others enhance fat burning by speeding up your metabolic rate. Some do both.
With so many products to choose from, it can be hard to decide which one is right for you. The main choice you need to make is whether to buy a product that contains a lot of caffeine or one that’s caffeine and stim-free. Caffeine IS an effective fat burner and energizer, but it also comes with a host of side effects, not least anxiety, and insomnia.
Once you have made this critical decision, you should find choosing the best fat burner much easier. Use your selected product following the manufacturer’s instructions and in conjunction with a sensible diet and exercise program, and you’ll soon be on your way to reaching your weight loss goals.
