Empowered With Movement to Prevent Obesity and Weight Regain

Summary

This study will help determine the appropriate type, amount and intensity of physical activity most beneficial for preventing weight regain after weight loss in older adults.

Conditions

• Obesity
• Weight Loss
• Sedentary Lifestyle

Interventions

BEHAVIORAL

Weight loss

All participants will undergo a dietary WL intervention designed to elicit behavioral changes leading to decreased caloric intake sufficient to yield a \~10% loss of initial body mass. The WL intervention includes nutrition education, state-of-the-art behavioral methods for promoting WL, and strategies that optimize self-regulation.

BEHAVIORAL

Exercise

Perform structured aerobic exercise (mostly treadmill walking) of moderate-intensity for 4-5 days/week, progressing to a duration of 200 min/week. Participants will attend center-based sessions for at least 3 days/week during the first intensive 6-month phase and at least one day/week during the second 3-month transition phase (months 7-9), with recording of home-based exercise for the other 2-4 days/week.

BEHAVIORAL

Sitless

Encouraged and taught to reduce sedentary behavior (SB) during waking hours. The SitLess treatment targets increases in postural shifts and light, spontaneous physical activity (SPA) (MET level \<3).
