Abstract

Objectives: The aim of this study was to evaluate the effects of 8 wk of time-restricted eating (TRE) along with a caloric restriction on metabolic profile, metabolic rate, symptoms of mood, and eating disorders and weight loss in women with overweight or obesity. Methods: Women age 18 to 59 y with a body mass index of ≥25 kg/m2 were enrolled in this parallel-arm, randomized, clinical trial. Participants were randomly allocated into two groups (8-h TRE or non-TRE group) using a 2:1 allocation strategy. Both groups received a diet plan with caloric restriction. Body weight, resting metabolic rate, metabolic profile, and symptoms of mood and eating disorders were evaluated at baseline and on follow up. Results: Thirty-six subjects were included in this study, with 24 in the TRE group and 12 in the non-TRE group. Subject in the TRE group showed more pronounced loss of weight, body fat mass, and fat-free mass than those in the non-TRE group. These losses were not associated with changes in resting metabolic rate, metabolic profile, and eating or mood disorder symptoms. Conclusions: This study showed that 8 wk of TRE does not influence behavioral parameters in individuals with overweight or obesity, but could lead to weight loss.
