Summary

Summary

An RCT in 78 police officers with BMI over 30, randomised to a weight-loss diet with carbohydrates concentrated at dinner or to a conventional control diet, over six months. **The experimental group lost more weight, abdominal circumference and body fat**, and reported less hunger. Fasting glucose, average daily insulin, HOMA-IR, lipids, CRP, TNF-α and IL-6 all improved more than in controls. The direction is the opposite of the common claim that carbohydrates at night make you fat.

Editorial review

Bibliographic checks are made by querying Crossref and PubMed. Content checks are made by AI matching the record against the original abstract; they are not expert judgements of validity. Every record is reviewed by the site operator before publication. What has not been checked is shown rather than hidden. About our verification process
