Protein and Resistance Exercise to Stop Sarcopenic Obesity Now
Sponsor: University of Alabama at Birmingham
Summary
The purpose of this study is to examine the separate and combined effects of a high-protein (HP) diet and resistance training (RT) on body composition and potential biological moderators of body weight in women and men \>50y. All participants will receive dietary physical activity guidance through our group-based weight loss program, State of Slim (SOS). The SOS program will be delivered via the Zoom videoconferencing platform. These participants will be randomized to receive either a counseling-based HP diet plan or RT plan. Body composition assessments at 8 wk will identify responders and non-responders; the latter will be re-randomized to "augment" (HP: add protein supplements; RT: supervise RT) or "combine" (HP with protein supplements + supervised RT).

Conditions
Interventions
High Protein Diet Counseling
16 week group-based weight loss program with counseling to consume a high protein diet. Approximate macronutrient distributions (carbohydrate:protein:fat) will be 32%:40%:28%.
Resistance Training Counseling
16 week weight loss program with resistance training counseling. Participants receive counseling to follow a full-body and progressive resistance exercise training program using resistance bands that are provided by the study.
Intensify Initial Intervention
For non-responding participants initially assigned to receive high-protein dietary counseling, whey protein supplements will be provided to participants with instruction to consume the supplement twice daily. For non-responding participants initially assigned to receive resistance exercise training, participants will receive 2 days per week of small-group supervised resistance exercise training.
Combined Supplement and Supervised Resistance Training
Non-responders from either initial randomized group assigned to this intervention receive the twice daily protein supplements and twice weekly small-group supervised resistance exercise training sessions.
