Increased weight-load improves body composition by reducing fat mass and waist circumference, and by increasing lean mass in participants with obesity: a single-centre randomised controlled trial.

ABSTRACT:

Background

To investigate the effects of increased weight-loading on body weight, body composition, fat mass distribution, physical activity and energy balance in individuals with obesity.

Methods

This single-centre non-blinded randomised controlled trial was conducted from August 1, 2021, through February 28, 2022. Adults with obesity class 1 (body mass index, BMI 30-35 kg/m²) were assigned to wear either a heavy (high load; 11% of body weight, n = 28) or light (low load; 1% of body weight, n = 30) weight vest for 8 h per day over 5 weeks.

Results

High-load treatment reduced fat mass (mean difference - 2.60%; 95% CI - 3.79, - 1.41) and increased lean mass (mean difference 1.40%; 95% CI 0.37, 2.42), with no significant effect on body weight. Fat mass reduct
