For our rankings, we preferred only products that included clinically-backed ingredients that are proven to be both safe and effective for male specific fat loss. This included ingredients such as caffeine, 5-HTP, and yohimbine.
Controlling your appetite is imperative for weight loss, which is why we rewarded supplements like PhenQ that included potent satiety inducing ingredients. The best fat burners also help speed up your metabolism. Instant Knockout both speeds up your metabolism and suppresses your appetite, which is why it was ranked #1.
It’s common to lose muscle when you’re in a fat-burning state, which is why we included fat burners that included ingredients to preserve lean muscle. Crazy Mass Cutting Stack appeared in our top 5 because of its potent ability to protect your muscle while still slashing fat. Lean-XT has a similar effect, thus it followed closely behind.

Another powerful fat burner for men is caffeine, which increases your metabolic rate and the fat-burning process. Caffeine also provides your body with a host of other benefits, such as improving your memory, energy, focus, and cognitive functioning. One meta-analysis looking at the effects caffeine had on weight loss found that caffeine successfully supports weight loss though variety of pathways (2).

Aside from increasing your lean muscle mass, taking the right supplement can aid this as well.

According to the research, the participants resting metabolic rate significantly increased (8).
Another 2016 study involving 13 female participants showed a substantially increased resting metabolic rate from the consumption of a single-dose thermogenic supplement (9).
