«Fat burners melt fat on their own»
Nuanced
What the evidence says
Aside from caffeine (a small effect on expenditure and performance), most 'fat burners' have trivial or non-existent effects. None work without a calorie deficit. Your money goes further on quality food, protein and sleep.
How settled this is
Only caffeine has support, and its effect is modest.
