Best Protein | Best Mass Gainer | Best Pre-Workout | Best Fat-Burner

Everyone’s weight-loss journey is different and personal, but the fundamentals that power it should be the same: consistent exercise and strategic nutrition. When you have those in place, a fat burner can help you turn up the heat or prepare for an important deadline.

These 10 different fat burners are all favorites of our fitness community to make weight control just a little more manageable and tolerable. As part of a complete, healthy plan to lose weight, they’re designed not only to help you see better results, but also feel better doing it.

Key ingredients: Caffeine, choline, alpha GPC
Caffeine per serving: 200 mg
Rating: 9.4 out of 10

When it comes to the energy you get from your fat burner, you need to think about quality, not just quantity. More caffeine is not necessarily better, especially if it leaves you jittery and with the attention span of a 3-year-old. One of our highest-rated fat-burners, QuadraLean blends nootropic ingredients with green-tea-derived caffeine into its stimulant formula for laser-focused energy that keeps your head in the game.*

Best Contest-Prep Fat-Burner: Beverly International 7-Keto MuscLean

://www.bodybuilding.com/images/2021/april/best-fat-burners-supplements-of-2021-4-700xh.jpg”/>

Key ingredients: 7-Keto DHEA, green tea, guarana
Caffeine per serving: 110 mg
Rating: 9.1 out of 10

This pill-based formula has been a staple in the repertoire of serious physique athletes since 2003. There are no fly-by-night ingredients here! 7-Keto DHEA, the flagship ingredient in 7-Keto MuscLean, has been extensively tested and patented for its effects on weight loss. It also takes a “just enough” approach to caffeine, with around the amount of a cup of coffee. This allows you to still prioritize sleep, which is crucial if you’re calorie-deprived and training hard.*

://www.bodybuilding.com/images/2021/april/best-fat-burners-supplements-of-2021-5-700xh.jpg”/>

Key ingredients: Caffeine, acetyl L-carnitine, L-tyrosine, Capsimax
Caffeine per serving: 200 mg
Rating: 8.5 out of 10

Key ingredients: Caffeine, L-tyrosine, Capsimax, green coffee
Caffeine per serving: 200 mg
Rating: 8.6 out of 10

We’ve all known someone who decided to lose weight, then transformed into a cranky, moody, miserable human being who complains constantly about…well, everything. Ripped Juice EX2 contains a blend of nutrients, herbs, and stimulants to support mood, energy, and appetite control to make your weight-loss journey less painful for you and everyone around you. Potent ingredients like N-acetyl tyrosine, a more bioavailable form of tyrosine, add up to an efficient formula that fits in just one capsule per serving.*

Best Nighttime Fat Burner: EVL NiteLean

Key ingredients: Melatonin, L-theanine, GABA, 5-HTP
Caffeine per serving: 0 mg
Rating: 9.9 out of 10

Good sleep is possibly the most underrated fat burner of all. Especially when you’re on a calorie-restricted diet, research has shown that the better you sleep, the better your weight-loss results. It also helps you focus and make good nutrition decisions; ever notice your carb cravings increase when you haven’t slept enough?

Our reviewers note that NiteLean’s stimulant-free blend helped them fall asleep, but also helped them wake up feeling ready to attack their workouts the next day.

Best CLA: Signature CLA Weight-Loss Supplement

://www.bodybuilding.com/images/2021/april/best-fat-burners-supplements-of-2021-8-v2-700xh.jpg”/>

Key ingredients: Conjugated linoleic acid (CLA)
Caffeine per serving: 0 mg
Rating: 8.6 out of 10

CLA is a popular nutrient for helping hold onto muscle mass as you lean down, so your workouts, body composition, and hard-earned definition don’t become casualties of your diet. Since Signature CLA is completely stimulant-free (it’s actually a healthy, naturally-occurring polyunsaturated fat that helps you lose fat), this is a great weight-loss supplement to add any time of day if you’re sensitive to caffeine, or in addition to a stimulant fat burner.*

Best Diuretic: MHP Xpel Maximum Strength Diuretic

://www.bodybuilding.com/images/2021/april/best-fat-burners-supplements-of-2021-9-700xh.jpg”/>

Key ingredients: Juniper berry fruit, dandelion root
Caffeine per serving: 75 mg
Rating: 8.9 out of 10

Diuretics cause you to lose water weight, not actual fat. That said, water weight and fat weight both look the same from the outside. MHP Xpel is a favorite of physique athletes to “peak” for an upcoming special event like a contest or photo shoot. In addition to its herbal diuretic blend, it includes green tea and guarana for a little energy bump and appetite support.

Best Women’s Fat Burner: NLA Shred Her

://www.bodybuilding.com/images/2021/april/best-fat-burners-supplements-of-2021-10-700xh.jpg”/>

Key ingredients: Green tea, taurine, caffeine
Caffeine per serving: 170 mg
Rating: 8.5 out of 10

If you’re a woman, especially a petite woman, the level of stimulants contained in fat burners formulated for men can be overkill. NLA’s all-natural fat burner is formulated and dosed specifically for women, with just enough stimulants to support fat loss and help with appetite, but not enough to send you to the moon. And since two capsules make a serving, you can even take just half a dose at a time. This is helpful if you also drink coffee, or if you want to spread your fat burner’s effects over the day.
