What’s to come

Many weight loss supplements and fat burners on the market are geared toward both men and women.
However, men tend to have different needs when they want to lose weight and burn fat. They require a higher dosage due to overall body mass and many also favor ingredients that target muscle growth simultaneously.
Some of the best fat burners for males feature natural ingredients such as green coffee bean. We dig into the details of the best fat burner for men and a few others, too.

Best Fat Burners for Men

It requires more than a simple magic capsule if you want to burn fat successfully. The process asks that you optimize your metabolism and suppress your appetite. Keeping a close eye on nutrition and a strict workout regime makes a huge difference, too.
This means you want a well-rounded fat loss supplement that provides numerous benefits, not only to lose weight but maintain energy levels while you’re doing it.
Each of the weight loss supplements on our list may have something to offer you, whether you need a stimulant free option or a serious boost. They mainly focus on natural ingredients.
This includes thermogenic burners, similar to Burn XT, Vintage Burn or Hydroxycut hardcore, but without the raspberry ketones or garcinia cambogia.
What does science have to say?

1. Burn Lab Pro — Best Overall

Burn Lab Pro is a fat burner made exclusively for men. The company is confident that this supplement can:

  • Support intense training
  • Help you gain muscle
  • Lose fat

You take two pills per day, pre workout and a jar contains a month’s supply. It’s gluten-free and a friendly option for vegans.

How Does It Work?

Ingredients in Burn Lab Pro include:

  • Capsimax cayenne pepper extract
  • GTF chromium (as Nutrigensis)
  • Calcium
  • BioPerine black pepper extract
  • ForsLean (Coleus Forskohlii root)
  • HMB (B-hydroxyl B-methylbutyrate)

Capsimax cayenne pepper extract promotes better blood circulation, digestion and metabolism by the heat it creates in the body [1].
GTF chromium (as Nutrigensis) also supports metabolism, which may help speed up the rate at which you lose fat [2].
Calcium makes this supplement a thermogenic fat burner like Burn XT. It’s proven to raise the body’s temperature level. This may prompt a fat burning response [3].
BioPerine black pepper extract might also be another ingredient on this list for boosting metabolism and digestion.
ForsLean (Coleus Forskohlii root) comes from a tropical plant and it’s promoted as a substance for building lean body mass, aka muscle. It also contains enzymes that help free up fatty acids the body burns as fuel. This root could enhance weight loss [4].
HMB (B-hydroxyl B-methylbutyrate) is in the essential amino acid, leucine. Studies show it may help lower fatigue, improve performance and build muscle mass simultaneously [5].

Burn Lab Pro Side Effects

As far as we know, there are no negative effects with this natural formula and ingredients. While many fat burners feature stimulants that can cause restlessness, irritability and insomnia, Burn Lab Pro doesn’t go there.

2. Instant Knockout — Best for Gains

Instant Knockout was made by men, for men. It’s used by pro boxers and MMA fighters alike, like Diego Sanchez, for example. This indicates it ups your performance and energy, while working as a fat burner.
Going into lean mode like the pros and not suffering during the process is the point of this supplement, but you’ll have to consume four capsules throughout the day.

How Does It Work?

This fat burner contains a whopping 10 ingredients.
The first six ingredients are featured in products above:

  • Chromium
  • Green tea leaf extract
  • Glucomannan
  • Caffeine
  • Green coffee bean
  • Cayenne pepper seeds

Chromium and cayenne may enhance metabolic processes and digestion for a better chance at fat loss.
Green tea extract, caffeine and green coffee bean are the stimulants and antioxidants here. Caffeine provides energy for the body in stressful situations like fat burning scenarios.
Glucomannan might ease water retention, due to its antiinflammatory characteristic. This plant might be useful for appetite suppression too.
Instant Knockout also includes the following ingredients:

  • Vitamins B6 and B12
  • Piperine
  • Zinc

Vitamins B6 and B12 function as essential vitamins. They offer support with energy, brain fog and physical performance, all elements of the weight loss process [13] [14].
Piperine is another pepper, similar to cayenne. This spice helps calm inflammation, water retention/bloating. It may improve digestion overall and break down fat deposits [15].
Zinc improves immunity, which can take a hit when the body is under the stress of a strict diet and exercise plan. It also helps convert food into energy, aiding in expenditure and fat burning capabilities [16].

Instant Knockout Side Effects

One of the biggest pros in Instant Knockout, similar to many supplements, is its energetic boost.
You might experience insomnia if the dose of stimulants is too high for you. We recommend easing into the product for this reason.

3. PhenQ — Best for Water Retention

PhenQ functions as a weight loss supplement that’s made to help you burn fat, suppress your appetite, raise energy levels and reduce inflammation/water retention.
It’s another fat burner and one of the supplements with mostly natural ingredients and comes with a money-back guarantee, should it not bring the results you crave.

How Does It Work?

The PhenQ fat burner ingredients feature:

  • Capsimax powder
  • L carnitine
  • Nopal
  • Caffeine
  • Chromium picolinate
  • α-Lacys Reset® (all rights reserved)

Capsimax powder, similar to the extract, amplifies heat in the body, working towards better metabolic processes.
L carnitine functions as an amino acid, elevating energy production. L carnitine may enhance fat loss and recovery after exercise, too [6].
Nopal comes from a cactus plant and is shown to support metabolism and reduce inflammation [7]. This helps lower water retention in your body.
Caffeine features as the stimulant here. Caffeine provides a boost in energy levels and focus while maintaining a low calorie diet for fat burning.
Chromium picolinate might improve your nutrition overall and enhance metabolism, too.
α-Lacys Reset® (all rights reserved) is a patented combination that includes magnesium. It may support energy production, weight loss and appetite suppression [8].

PhenQ Side Effects

This fat burner supplement comes with no harsh effects that we know of, although this does depend on the individual and one’s sensitivity.
Do be aware that it contains caffeine as a stimulant.

4. PhenGold — Best for Stress

The PhenGold body fat burner focuses on three categories: concentration, metabolic levels and appetite suppression. It contains a few ingredients already covered here like green tea extract, pepper and amino acids, but it’s made to help lower stress, too.
This company offers promo codes and bundles on a regular basis.

How Does It Work?

The PhenGold product features the following:

  • Cayenne pepper
  •  L theanine
  • Green tea
  • L tyrosine
  • Green coffee
  • Rhodiola SP

Cayenne pepper functions similarly to other peppers on this list. It lends the body heat, aiding in multiple processes including but not limited to digestion and metabolism.
L theanine is naturally found in both green and black teas. This amino acid might help fight stress and anxiety, thus inflammation, as well [11].
Green tea as an antioxidant might not only boost nutrition all-around. Green tea extract supports relaxation and heart health, too, both important factors when the body is under stress.
L tyrosine is another amino acid and it works to boost your mood. Research is limited but it might help with appetite suppression.
Green coffee as a stimulant is found in a variety of fat burners. The purported effects are tempting but it could only be moderate.
Rhodiola SP is an herb that might help improve body performance overall and decrease stress [12]. It may aid in losing belly fat, in particular, but studies are inconclusive at this time.

PhenGold Side Effects

PhenGold doesn’t come with adverse reactions, to our knowledge. Even the stimulants in this supplement are relatively minimal.

5. Lean Bean — Best Lightweight

LeanBean is marketed directly to women, but it’s not a gender-selective supplement. In fact, it could make for a good lightweight option for one who requires an energetic boost without the entire package.
It claims success in the following categories:

  • Burn fat
  • Suppress appetite
  • Raise metabolism
  • 100 percent natural

Delivery is free and you’ll get a money back guarantee, as well.

How Does It Work?

This product is mainly made of stimulants, ingredients including:

  • Green coffee
  • Grains of paradise
  • Caffeine
  • Green tea
  • Glucomannan

Green coffee might aid in weight loss by boosting metabolism and lowering inflammation. It’s one of three stimulants in this supplement, offering up energy to boot [9].
Grains of paradise is a lesser known spice, similar to pepper. It might help decrease body fat by increasing energy expenditure and digestion.
Caffeine comes in as the second stimulant made to improve focus when losing weight.
Green tea doesn’t only help you battle fatigue, it also supports your metabolism [10]. It’s an antioxidant, too, offering a hand to overall nutrition.
Glucomannan comes from the konjac plant. This root might help curb your appetite while maintaining a strict diet which is challenging.

LeanBean Side Effects

The only major player to watch for here is the fact that this supplement contains three stimulants. It could create a feeling of jitteriness or an upset stomach because of this, but it’s not a given.

6. Zotrim — Best for Curbing Appetite

The Zotrim product markets itself with a focus on suppressing the appetite. It may be suitable for those whose cravings are a weak point.
The stimulant dosage is low, equating to around the same amount of caffeine that exists in a regular cup of coffee.

How Does It Work?

Zotrim ingredients are:

  • Damiana
  • Vitamins B6 and B3
  • Guarana
  • Yerba mate
  • Caffeine

Damiana is a plant that works to slow down the emptying of your bowels, which means it keeps your appetite at bay for longer [17].
Vitamins B6 and B3, like many B vitamins, support energy production and blood cell formation. They lighten chronic fatigue, which can be a result of weight loss.
Guarana comes from Brazil and this herb is both a stimulant and metabolic booster. It might decrease the formation of fat cells, aiding in lean body mass [18].
Yerba mate is a gentle stimulant. It comes with a slew of potential benefits like the suppression of one’s appetite, lowered inflammation, better metabolism and more.

Zotrim Side Effects

The natural fat burning ingredients in Zotrim shouldn’t cause adverse reactions in most customers. With those who have stomach sensitivities, it might cause minor bloating or nausea, though.

How Can Fat Burning Supplements Help You Lose Weight?

Research tells us that fat burners work in some scenarios. The ingredients in fat burning supplements for men help you lose weight by ramping up metabolic processes, suppressing your appetite and burning fat.
They also:

  • Boost energy
  • Are backed by science
  • Support muscle retention
  • Don’t require a prescription

For success, it’s imperative that alongside using a fat burner, you follow manufacturer and medical guidelines, too. Most advise that you also exercise and eat a low calorie diet for the best results.

What Is the Male Fat Burner Hormone?

Multiple hormones aid in fat burning but the big one here is testosterone. Having low T levels can lead to easy weight gain. This is another reason why men need to continue a disciplined exercise regime for fat loss.

How to Choose the Best Fat Burners for Men

Each fat burner has a different focus and ingredients to match, whether that’s to curb cravings or increase energy levels. Some are more well-rounded than others and it’s up to the consumer to decide which product is best for them.
For example, if you have difficulties with blood pressure or experience anxiety due to a high caffeine intake, you’ll want to avoid a fat burner that’s high in stimulants.

Are Fat Burners Legal?

Any fat burner approved by the FDA (Food and Drug Administration) is legal. Not all fat burners are, though, but each one on our list qualifies.

Are Fat Burners Safe?

Generally speaking, any fat burner that contains only natural ingredients and is FDA approved will be a safe option. Many fall into this category.
A fat burner that’s safe for one individual, may not be for another one, though. As we’ve mentioned, each person or man has specific needs. It’s a good idea to discuss this with a doctor before consuming a fat burner to be sure.

Do Fat Burners Have Side Effects?

All of the fat burners on our list come with minimal negative reactions overall. This is because the majority of the fat burning ingredients described here are natural.
More than likely, the worst side effect you’ll experience with one of these fat burners is an upset stomach or jitteriness.

How To Use Fat Burners?

Each fat burner manufacturer lays out specific instructions for the product.
This includes when to take the supplement and what other stipulations exist. For example, can you take your chosen product alongside something else? Determining these factors will be important in helping you reach your goals.
Many high quality fat burner supplements also provide tips and suggestions on their official sites to make the most of your journey. Companies like Evlution Nutrition go further and offer loads of other products to support weight loss, like T boosters and more.


Many fat burners feature ingredients like caffeine, green tea extract and L carnitine to aid with losing weight and burning fat.
These supplements might help boost nutrition all-around, as well, depending on what they offer. The best fat burner for men will help you burn stored fat, without losing out on muscle gain in the process.
One of the best options is Burn Lab Pro. It’s free of stimulants and the pros of this product include weight loss support, along with training recovery and more. If you want to lose fat, it could be possible, so long as you maintain a strict diet and workout plan at the same time.
Make sure to consult your doctor should you have any negative experiences with fat burners.
