Abstract

BACKGROUND: Behavioural weight-loss interventions utilising portion-controlled meals (PCMs) produce significant decreases in weight. However, their impact on diet quality during weight maintenance is unknown. The present study aimed to assess the influence of a weight management intervention employing PCMs and increased physical activity on diet quality during weight loss and weight maintenance. METHODS: One hundred and ninety-seven overweight and obese adults [67% women; mean (SD) BMI = 34.0 (4.6) kg m-2 ; age = 46.1 (8.9) years] completed an 18-month trial. The weight-loss phase (0-6 months) consisted of energy restriction, which was achieved using PCMs plus fruits and vegetables and increased physical activity. During weight maintenance (6-18 months), participants consumed a diet designed to maintain weight loss. Body weight and dietary intake were assessed at baseline, and at 6, 12 and 18 months. The Healthy Eating Index-2010 (HEI) was calculated using data obtained from 3-day foo
