Summary

Aim of the study is to investigate the effects of high-protein, ultraprocessed foods on the regulation of energy balance in a metabolic chamber. The primary outcome parameter of the study is the energy balance (ad libitum energy intake and energy expenditure).

Detailed description

Each of the two study weeks starts with a 3-day run-in period with controlled diet at home, following 48 hours in a metabolic chamber. On the day the participants leave the metabolic chamber, they keep a food record over the rest of the day at home. 1. week: meals containing 30 % protein (80 % ultraprocessed high-protein foods), physical activity level (PAL) 1.45, 2 intervention days in the metabolic chamber: ad libitum energy intake 2. week: meals containing 13 % protein (80 % ultraprocessed foods with moderate protein content), physical activity level (PAL) 1.45, 2 intervention days in the metabolic chamber: ad libitum energy intake

Interventions

Type	Name	Description
OTHER	high protein diet	48 hours intervention with a 'high protein' ad libitum diet (30 % protein; 80 % commercially available ultraprocessed foods) to measure energy balance in a metabolic chamber at physical activity level of 1.45
OTHER	moderate protein diet	48 hours intervention with a 'moderate protein' ad libitum diet (13 % protein; 80 % commercially available ultraprocessed foods) to measure energy balance in a metabolic chamber at physical activity level of 1.45
