best fat burner for men

Getting rid of those extra pounds accumulating over the years can be difficult. You may be doing all the right things – exercising, and eating a healthy diet, but you may still not seeing the fat melt away. Sometimes your body needs a boost, which is where our top eight fat burners for men shine. While it’s not generally recommended that you stop doing all the other things that make you healthy, fat burner supplements can help kick-start your metabolism and help you acheive your weight loss goals. 

Supplements are not silver bullets that will solve your weight loss issues. Supplements are designed to be additions to a healthy diet and lifestyle. You’ll want to incorporate a well-designed exercise plan, get plenty of sleep, and eat a balanced diet. After you have these aspects of your lifestyle in line, fat-burning supplements can really help you reach your desired weight more quickly. There are many ins and outs to picking the right supplement, which you’ll have to consider. 

There are multiple ways in which supplements help you reach your ideal weight. Some contain ingredients to increase your metabolism, others sensitize your insulin response, and others use ingredients to decrease your appetite. These mechanisms can be effective, but figuring out what is preventing you from achieving your weight goal is the first step. 

If you tend to overeat, you’ll want to stick to a product that has a primary ingredient for appetite suppression. However, those who are eating healthy, exercising, and still having difficulty losing weight may want to choose a product that increases metabolism or fat-burning pathways.

  • Caffeine
  • Chromium
  • Green Tea or Green Tea Extracts

  • Cayanne Pepper or Capsacian
  • Black Pepper Extract or Bioperine

These are by no means a comprehensive list of ingredients, but they are some of the most common ones you will come across.

Best Fat Burner For Men 2023


  • Clinical research that supports efficacy
  • Money-back guarantee
  • Multiple fat burning mechnisms 
  • Artificial dyes used

PhenQ comes in at our top spot with a money-back guarantee and clinical research studies supporting the fat-burning capabilities of this supplement. 

PhenQ is a supplement that takes advantage of ingredients that help burn excess fat through multiple mechanisms of action. Some ingredients help sensitize your insulin response, while others speed up your metabolism. The company has also included ingredients that aid in decreasing your appetite. The company ensures that you get pure and quality ingredients by manufacturing its products in the USA and United Kingdom using GMP-approved facilities. 

The money-back-guarantee is also fair without hidden caveats. If you’re unhappy with your purchase after using two bottles, return the empty bottles along with any unopened bottles within 67 days, and you’ll get a full refund. The only downside is that you’ll have to pay for shipping costs.


  • 90-day money-back guarantee
  • No artificial ingredients
  • Decreases appetite
  • Six capsules per day

LeanBean takes our second spot for the best fat burner with a formula tailored specifically to decrease appetite. 

LeanBean has created a supplement combining powerful ingredients such as glucomannan, Garcinia Cambogia, and others. Glucomannan[1] has a unique mechanism in which it works to aid individuals in losing excess fat by which it combines with water creating bulk, and suppressing appetite. The company packs its supplement with more than 3 grams of fiber daily! Since this ingredient is a bulking agent, you’ll want to drink lots of water when taking this supplement. 

Green coffee is another powerhouse ingredient the company utilizes and differs from regular coffee in that the green coffee bean is not roasted. Roasting changes the chemical makeup of the ingredient, and for fat-burning, you’ll want to stick to the green coffee bean.


  • Manufactured in the USA
  • Soy, Gluten, and Dairy Free
  • No fillers or artificial ingredients
  • Price

PhenGold is a well-rounded supplement with ingredients to ignite fat burning and suppress appetite. With clean, pure ingredients, the only downside is the price, but you’ll get a discount if you order more than one bottle at a time. 

PhenGold has eight ingredients to help you shed those unwanted pounds and vitamins to ensure your fat-burning metabolic pathways are optimally functioning. With each serving of this supplement, you’ll get a significant boost in energy and metabolism with 500 mg of green tea, 100 mg of green coffee, and 225 mg of caffeine. In addition, DMAE, L-theanine, and tyrosine are included by the company to improve mood, focus[2], and motivation. 

PhenGold is an excellent choice for a wide variety of individuals as the company specifically avoids common allergens including dairy, gluten, and soy in its products. This product is also vegan and vegetarian-friendly and devoid of unnecessary artificial ingredients.

Instant Knockout

  • Multiple fat loss supplement stak
  • Manufactured in a FDA-approved and GMP-approved facility
  • Affordable
  • Requires four dosings per day

Instant Knockout has a full line of supplements produced to the highest standards for dropping weight and getting shredded. The company also offers a free month of the cut formula when you purchase three months of the product. So you’ll get four months for the price of three! 

If you’re looking for a supplement with a full product line to support your weight loss goals, then you’ll find a perfect fit with Instant Knockout. The cut formula, which is this company’s weight loss product, contains some familiar ingredients such as glucomannan, green tea extract, and caffeine anhydrous. This formula also contains metabolism-boosting ingredients like cayenne pepper[3] and black pepper extract. Black pepper extract has the dual effect of enhancing other nutrient absorption[4] and activating specific receptors in the body that can increase body metabolism. 

You can also couple the cut formula with the Instant Knockout complete, which can be used as a meal replacement to keep you satiated throughout the day.

Prime Shred

  • Manufactured in the USA
  • Soy, Gluten, and Dairy Free
  • 100-day money-back guarantee
  • $15 return shipping fee

Prime Shred is a well-formulated supplement with all the leading weight loss ingredients at the middle of the market price range. 

Its money-back guarantee makes this brand stand out from its competitors. While other supplement brands offer a money-back guarantee, Prime Shred provides one of the most comprehensive in the industry. You’ll have 100 days to decide whether or not Prime Shred is for you; they only ask that you return any unused product you’ve purchased and pay a $15 shipping and administrative fee. In addition, they only ask that you give the supplement a fair try by using it consistently for 50 days. That’s a reasonable ask in our books!

The supplement has ten ingredients: green tea extract, DMAE, L-tyrosine, green coffee, L-theanine, Rhodiola, Bioperine, vitamin B complex, caffeine anhydrous, and cayenne pepper. The manufacturer suggests you take three capsules daily as the recommended serving size.

Ultra Omega Burn

  • Simple familiar ingredients
  • Manufactured at an FDA-approved facility
  • No artificial ingredients
  • Not varied fat burning ingredients
  • Not vegan friendly

Ultra Omega Burn is the ideal choice for those wanting to keep the variation of ingredients and the risk of side effects minimal. However, this product isn’t suitable for strict vegans as it’s made from fish. 

Ultra Omega Burn is precisely what the name suggests, a combination of Omega fatty acids. Over the years, omega-3 fatty acids have been a hot topic as research studies have shown various health benefits[5] from regularly supplementing these ingredients. But did you ever think of using Omegas for weight loss? This supplement contains a nutrient called Palmitoylethanolamide[6], an Omega-7 fatty acid obtained from olive oil, which may increase your body’s fat-burning capability. 

Besides Omega’s, this supplement also contains green tea extract and caffeine, enhancing fat burning. In addition, the company includes chitosan, which will work to suppress your appetite. If you’re still skeptical, try the product, as a one-year money-back guarantee covers you.

Burn Lab Pro

  • Multiple fat burning ingredients
  • Stimulant-free
  • Soy, Gluten, and Dairy Free
  • Only a 30-day money-back guarantee

If you’re looking for a stimulant-free fat burner with no unnecessary additives, then you may have found your perfect product in the Burn Lab Pro. 

Burn Lab Pro utilizes five primary ingredients in their supplement: Coleus Forskohlii, Chili Pepper Extract, ß-Hydroxy ß-Methylbutyrate, Cultured Glucose Tolerance Factor (GTF) Chromium, and Black Pepper Extract. This supplement will be ideal for a wide range of individuals as its soy, gluten, and dairy-free. Burn Lab Pro designed this product to burn fat, increase exercise intensity, and increase muscle growth. 
The company has added ß-Hydroxy ß-Methylbutyrate for increased muscle growth and exercise intensity. Coleus Forskohlii has been added by the company to help burn excess fat and increase muscle growth. The Chili Pepper Extract is added to boost metabolism, while the Cultured Glucose Tolerance Factor (GTF) Chromium regulates metabolism and decreases appetite[7].


  • Promotes restful sleep
  • Manufactured in the USA in a cGMP certified facility
  • No fillers or dyes
  • LeanPM melatonin-free contains carrageenan

If you’re looking to lose weight while you get a restful night’s sleep, then you’ll want to take a closer look at LeanPM. 

This company makes two versions of the LeanPM supplement, one containing melatonin and the other being melatonin-free. The melatonin LeanPM includes ECGC, L-theanine, 5-HTP, Melatonin, Bioperine, magnesium, and vitamin B6. 

ECGC, L-theanine, 5-HTP, Rutaecarpine, Lemon Balm, magnesium, and vitamin B6 are included in the Melatonin-free version.

Both the LeanPm versions are stimulant-free, which makes sense, given it’s a sleep-promoting supplement. Since this supplement was designed to be taken at night, you can combine this supplement with another daytime fat burner. Some research shows that carrageenan may be linked to irritable bowel disease (IBD)[8] activity, so those with preexisting IBD may want to stick to the melatonin-containing LeanPM. 

Potential Side Effects

The potential side effects of fat burner supplements depend on the ingredients included in the supplements. May companies imply or even blatantly advertise that there are no side effects since these are natural ingredients, but this isn’t true. While many natural ingredients have minimal side effects, you can expect side effects from anything that has a real physiological response on the body. 
For example, caffeine anhydrous is a natural ingredient, but if you ingest too much caffeine, you may experience, among other symptoms[9]:

  • Irritability
  • Nervousness
  • Rapid Heartbeat
  • Trouble Sleeping

Make sure to do a little extra research on the ingredients included in the particular supplement you select, so you’re well informed on the potential side effects.
