Brief summary

The present study was based on secondary analysis using the non-intervention control conditions of five separate studies with common measures. The current analysis examine the indirect and direct effects of fat-free mass, fat mass and resting metabolic rate on energy intake in individuals at or close to energy balance.

Detailed description

The current analysis examine the indirect and direct effects of fat-free mass, fat mass and resting metabolic rate on energy intake in individuals at or close to energy balance. The present study was based on secondary analysis using the non-intervention control conditions of five separate studies conducted between the dates of 1998 and 2007. In total, 242 subjects (114 males; 128 females; mean body mass index = 25.6 ± 5.0 kg/m2) were included. In these studies, body composition (air displacement plethysmography), energy expenditure (indirect calorimetry and flex heart rate) and energy intake (weighed dietary records) were measured using common procedures.
