What are fat burners?

Fat burners are supplements claiming to accelerate fat loss, often using stimulants, mild thermogenics, or appetite suppressants. Their effects are small compared to diet and training.

How does it work?

Ingredients like caffeine raise energy expenditure slightly and reduce appetite. Some add yohimbine or capsaicin with modest effects. Benefits are minor and offset by tolerance and side effects if lifestyle is not aligned.

Practical application

Focus on a sustainable deficit (0.5-1.0% body weight/week), high protein, and resistance training. If adding a burner, start with caffeine alone to gauge effect. Avoid stacking stimulants; watch sleep and heart rate. Skip if anxious or sensitive. Many “proprietary blends” underdose key ingredients—verify labels.

FundamentalsDeficit + protein + lifting first.
