In a two-year Duke University study, participants assigned to reduce calories by 25% achieved an average reduction of 12%, and their biological age increased by 0.11 years per year, compared with 0.71 years per year among people eating their usual diets.
Notes on verification
Confirmed by Duke Health press release and peer-reviewed CALERIE biobank study (Journals of Gerontology, Series A, 2018), with matching figures for calorie reduction and biological aging rates. [tier=gold indep_score=0.867 clusters=3 claim_tier=notable]
