Effects on mood and satiety of 4 days of partial energy deficit (60%) or energy excess (150%)
Abstract
We previously demonstrated that up to 48‐h of near total calorie deprivation does not affect mood or cognitive performance but does alter satiety. In this study we examined effects of partial energy deficiency (ED) and overfeeding (OF) on mood and satiety. Volunteers (10M, 4F, age 22 ± 2 yr, BMI 25.0 ± 3.8) underwent 4 days of EB, 4 days of ED (60% of energy balance (EB)), and 4 days of OF (150% of EB) in the laboratory. Macronutrient composition, daily activities and total energy expenditure were held constant. ED reduced self‐reported vigor compared to EB (p=0.02) as assessed by the Profile of Mood (POMS) state but OF had no effect on mood (Table). Both ED and OF affected perception of satiety as assessed with the SLIM questionnaire, with OF increasing satiety and ED decreasing it (p<0.001). This study indicates substantial, sustained underfeeding adversely affects mood but overfeeding does not, and that OF and ED both alter perception of hunger.
