The claimEvidence B · meta-analysis
16:8 intermittent fasting boosts metabolism
The evidence
TRE matches plain calorie restriction; no metabolic uplift. Harmful for pregnancy or eating-disorder history.
Why the claim spreads
Time-restricted eating went viral via best-selling books and influencer before/after photos; 'boosts metabolism' is far more clickable than 'it's just calorie restriction with a clock on it.'
