Weight loss isn't easy nor is it available in one-size-fits-all for most men. If it were, there wouldn't be so many different weight-loss diets and programs popping up every few years as the "Next Best Thing." You can achieve the greatest—and most sustainable—results through good old-fashioned nutrition (check out our list of foods that naturally burn fat) and consistent exercise. However, sometimes losing that last bit of belly fat in order to crush your transformation goals or participate in a bodybuilding competition can feel impossible.
That's where fat burners for men can potentially help. Fat burners aren't a magical pill, but the best ones do often feature ingredients that can help speed up your metabolism through thermogenesis, lipolysis, and increased testosterone production. Some fat burners can also act as an appetite suppressant or pre-workout if satiety and motivation are an issue.

SPECS
- Dosage: 2 tablets
- Ingredients: Capsimax powder, chromium picolinate, caffeine, nopal cactus, L-carnitine fumarate, magnesium stearate
- Form: Tablets
PhenQ is our pick for the best fat burner pills for men because of the five-pronged approach to weight loss—fat burning, reduction in fat accumulation, increased satiety to prevent food cravings, energy boosts, and balances in mood—all while using clean and natural ingredients in each tablet. PhenQ claims to burn fat and increase energy production through a-Lacys reset, a proprietary blend of ALA (alpha-lipoic acid), cysteine, and magnesium in combination with Capsimax powder for its thermogenic effect.(1) Additionally, the capsaicinoids found in Capsimax may help reduce fat accumulations by hindering the body's ability to produce excess fat cells.(2) Further, chromium picolinate, nopal cactus, and caffeine combine their powers to aid in satiety—or the feeling of fullness—by helping to reduce insulin resistance.(3) Lastly, PhenQ offers cognitive support in the form of l-Carnitine, a naturally occurring amino acid that has been shown to help increase energy production and power motivation.(4)
PhenQ has many favorable reviews from its users, but if you aren't happy with your purchase, the company does offer a 60-day money-back guarantee. Also, if you have any sensitivity to caffeine, keep in mind that the two-tablet serving contains 300 milligrams of it, which is the equivalent of roughly three cups of drip coffee.
Best For
- Users looking for clean, natural ingredients
- Men who want a fat burner with high thermogenic and appetite suppressant properties
- Those looking to purchase a larger quantity, as PhenQ offers bundle discounts

Best Fat Burner for Men Over 40 - Transparent Labs Fat Burner
SPECS
- Dosage: 2 capsules, twice daily
- Ingredients: Forslean, green tea extract, 5-HTP, L-tyrosine, L-theanine, caffeine anhydrous, white willow, cayenne pepper, synephrine HCl
- Form: Capsules
For men over 40, we recommend a good balance of thermogenesis with improved mental focus, helping to facilitate healthy and productive workouts.(5) Transparent Labs Fat Burner gets its thermogenic effects from ingredients like cayenne pepper (capsaicin), caffeine anhydrous, and synephrine HCL, the latter being a non-stimulant thermogenic agent. This product also contains some unexpected ingredients in its fat-burning formula including forslean (forskolin) and green tea extract. Forslean, or forskolin, has been shown to have positive effects on decreasing body fat stores and increasing testosterone production in men.(6) Green tea extract is thought to have antioxidant properties that help boost cognitive function and reduce inflammation.(7)
Further, Transparent Labs is a solid brand known for transparent labeling and ingredients with an excellent track record when it comes to sports nutrition and supplements. They recommend that you begin with half the recommended dosage in order to give your body ample time to adjust.
Best For
- Men looking for a thermogenic fat burner with clean, transparent ingredients

SPECS
- Dosage: 2 capsules, twice daily
- Ingredients: Acetyl l-carnitine, forslean, 5-HTP, rhodiola rosea, cayenne pepper extract, fucoxanthin
- Form: Capsules
As the majority of fat-burning supplements somewhat rely on stimulants to get the job done, it can be hard to find a quality, stimulant-free version. Luckily, Transparent Labs Fat Burner Stim-Free has all the potency of a stimulant-based fat burner without the high caffeine levels, making it an especially good choice for men who are past 50 and may not respond as favorably to highly stimulating formulas. This formula features 50 milligrams of cayenne pepper for a more natural approach to thermogenesis. It also uses acetyl L-carnitine and Forslean, potent ingredients that we have previously mentioned, both of which have been shown to help mobilize fat from fat cells and increase levels of satiety.(8) Lastly, the formula contains rhodiola rosea, a nootropic that has been shown to help combat fatigue and boost overall mood.
So, if you are caffeine-averse or prefer an evening training session, a stimulant-free fat burner like Transparent Labs Fat Burner Stim-Free could be an excellent option to help you meet your weight loss goals.
Best For

Benefits of Fat Burners for Men
There are many benefits to taking a supplemental fat burner for men, as long as it's being taken in tandem with a balanced diet and consistent training program. Fat burners often contain ingredients that can help increase your metabolism through thermogenesis and use this generation of heat to stimulate weight loss. Additionally, fat-burning pills will also include an appetite suppressant, such as caffeine, to increase your satiety and help you feel fuller for longer; thus preventing overeating or unnecessary snacking.
It is important to have realistic expectations when it comes to weight loss pills. They don't have the ability to burn off excess calories or reduce body fat without a concerted effort on your part. They function more as an aid or a boost to an already active lifestyle. Fat burners may be able to help you lose those last few stubborn pounds of belly fat in order to meet your goal weight, but they aren't a long-term plan to keep the weight off.
How We Chose the Best Fat Burners for Men
The ACTIVE Reviews Team narrowed down our list of the best fat burners for men by researching products from brands that we trust—like Transparent Labs and Kaged—with transparent ingredients, certifications, and positive word-of-mouth from reviewers. We also give extra points to products that have excellent customer service and money-back guarantees.
How to Choose the Best Men’s Fat Burner
Ingredients
There are a lot of common ingredients in the majority of weight loss pills for men. You should expect to see forms of caffeine and capsaicin for their thermogenic and appetite-suppressing effects. That said, men should pay closer attention to the label as not all fat burners will contain testosterone-boosting ingredients, so if that is important to you, you'll want to double-check.
Additionally, because a lot of fat burners, like some pre-workouts, contain stimulants, they work best when cycled. This means that you'll want to cycle your fat burner by taking a one-to-two-week rest period after about four-to-six weeks of use for better efficacy.
Dosage
Some fat burners have much higher caffeine levels than others, so it's best to start with a lower dosage at first in order to gauge how your body will react. Starting at the full dosage—especially when it's four pills—when you aren't ready can have adverse effects that could make you want to discontinue use. You also don't want to feel like you've wasted your time or your money by not taking the correct dosage. As always, if you're concerned about the best dosage for your needs, consult with your physician before taking a fat-burning supplement.
Certifications
Product certifications can either make or break your decision when choosing a fat-burning supplement. Athletes especially will want to look for products with formulas that are third-party tested or Informed Sport Certified in order to reduce the possibility of testing positive for banned substances. Also, products that are certified vegan or non-GMO may be a better fit for men with dietary restrictions or preferences.
Our Final Takeaway
The bottom line is that, even with a rigorous diet and exercise regimen, it can still be tough to burn off those last few pounds. Sometimes, you need a little help to optimize performance and jumpstart your metabolism. We hope this guide helps you locate the product best suited to help you achieve the trim, streamlined appearance you desire.
FAQs About Fat Burners for Men
Are fat burners safe for men to use?
Fat burners, and the majority of weight loss pills, are not regulated by the FDA and should be treated with some initial caution. The ingredients and the amount taken is where a lot of supplements cross over into dangerous territory, so always pay attention to labels and recommended dosages. Some fat burners, including many on our list, do feature natural, searchable ingredients that are combined in pill or powder forms to increase their effectiveness. If you're at all concerned about how your body will react to any of the ingredients in a fat-burning formula, consult with your physician and start with a smaller dosage at first to test how your body will react.
What are the potential side effects of using fat burners?
Fat burners that have high levels of stimulants like caffeine may come with negative side effects such as headaches and nausea, increased heart rate, and difficulty sleeping. If you work out in the evening, you'll especially want a stimulant-free fat burner in order to prevent the possibility of insomnia. Additionally, if you cycle your fat burner, which you should do every four-to-six weeks, you may experience the effects of caffeine withdrawal. This includes increases in fatigue, anxiety, and irritability.
While fat burners with clean, natural ingredients are mostly safe when taken at their recommended dosages, those with high blood pressure, liver problems, or over the age of 65 should probably either abstain from using these supplements or speak with a doctor beforehand.
Are fat burners effective for weight loss?
The short answer is that they can be effective due to ingredients chosen to increase your metabolism and satiety, but this will only be when used in conjunction with a well-balanced diet and exercise plan.
How long should men use fat burners before seeing results?
You should expect a trial period of two to three weeks before seeing results. According to the CDC, the safest—and most sustainable—rate for weight loss is about one to two pounds per week. If you find that you're losing more weight than the recommendation, consult with your physician.
