Long Term Weight Loss Diets and Obesity Indices: Results of a Network Meta-Analysis.

Background: Scientists have been investigating efficient interventions to prevent and manage obesity. This network meta-analysis (NMA) compared the effect of different diets [moderate macronutrients (MMs), low fat/high carbohydrate (LFHC), high fat/low carbohydrate (HFLC), and usual diet (UD)] on weight, body mass index (BMI), and waist circumference (WC) changes at ≥12 months.

Methods: We searched Medline, Embase, PubMed databases, and the Cochrane Library.
