Höchsmann C, Fearnbach N, Dorling JL, et al. - Two 8-week overfeeding studies, the PROOF Study (N = 25; 16 males; 16 African American; 24.1 years; 25.1 kg/m², inpatient) and the EAT Study (N = 35; 29 males; 20 White; 26.7 years; 25.5 kg/m², free-living), were analyzed to assess the effect of overfeeding on eating behaviors and psychological constructs.

• Participants in both the studies were overfed 40% above baseline (daily) energy requirements for eight weeks.

• Depressive symptoms increased and fear of fatness enhanced following 8 weeks of overfeeding.

• A reduction in hunger, desire to eat, and food cravings appeared during overfeeding.

• There were temporary changes in these outcomes; the changes subsided after overfeeding.

• Body dissatisfaction, which was linked with overfeeding/weight gain, remained after overfeeding.
