Abstract: Objectives: To compare the effects of weight loss with and without exercise on 1) dietary prescription adherence and 2) non-structured activity in postmenopausal women. Design: Longitudinal study. Setting: Clinical research setting with facility based exercise and nutrition education. Participants: Overweight and obese women, 45-76 years old. Intervention: 6 months of weight loss alone (WL; N=38) or with aerobic exercise (AEX+WL; N=41). Measurements: Cardiorespiratory fitness (VO2max), resting metabolic rate (RMR), seven day food intake, and physical activity (by Actical accelerometers worn in a subset subgroup: WL: N=10; AEX+WL: N=15) were assessed before and after the interventions. Results: Both interventions resulted in similar weight loss (~9%) and no signficant changes in RMR, while only the AEX+WL group improved VO2max (~10%). At baseline, the AEX+WL group consumed slightly more protein than the WL group (P
