The most studied natural fat-burning ingredient. EGCG increases metabolic rate by 3-4% and enhances fat oxidation during exercise. Look for 500mg+ standardised to 50% EGCG.
Shuttles fatty acids into mitochondria for energy production. Most effective when taken before cardio. Safe for daily use with no stimulant effect. Works best paired with exercise.
Increases thermogenesis and energy expenditure by 5-8%. Effective at 100-200mg per serving. Higher doses bring diminishing returns and sleep disruption. Cycle to avoid tolerance.
Do fat burners actually work?
Fat burners can modestly increase metabolic rate and energy expenditure, but they are not magic pills. Without a caloric deficit from diet and exercise, no fat burner will produce meaningful results. Think of them as a 5-10% boost on top of an already solid nutrition and training plan.
Are fat burners safe?
Reputable fat burners using studied ingredients like green tea extract, L-Carnitine, and moderate caffeine (under 300mg) are safe for most healthy adults. Avoid products with hidden stimulants, proprietary blends, or banned substances like DMAA. Always check FSSAI certification.
Should I take a fat burner every day?
Cycle fat burners 4-6 weeks on, 2 weeks off to prevent tolerance buildup, especially for caffeinated products. Stim-free options like L-Carnitine can be taken daily without cycling.
Can women take fat burners?
Yes. Most fat burners are unisex. Women may want to start with half the recommended dose to assess caffeine sensitivity. Stim-free L-Carnitine is a good starting point for women new to fat burners.
Fat burner vs green tea extract - which is better?
Green tea extract (standardised to EGCG) is the most researched individual fat-burning ingredient. Many fat burners are just green tea extract + caffeine + fillers at a higher price. If budget is tight, standalone green tea extract capsules give you the core benefit.
When should I take a fat burner?
Take it 30-45 minutes before your workout for maximum fat oxidation during training. Avoid taking caffeinated fat burners after 3pm to protect sleep quality. On rest days, take it in the morning with breakfast.
