Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the trial is to assess the effects of weight loss on functional status and lean muscle mass in frail, obese older adults (\>/= 60) who participate in a 6 month weight reduction intervention. Participants will be randomized into one of two study arms: Weight Loss Control: (n = 25) subjects follow a calorie-reduction diet for a weight loss of ≥10%; or Weight Loss-High Protein: (n = 50) subjects follow a calorie-reduction diet for a weight loss of ≥10%, with a high proportion of high quality protein at each meal. Intakes of \> 30g of high quality protein will be achieved three times a day by subjects in this group, predominantly all from animal sources and 60-70% of animal protein from beef. Subject criteria will include obese (\>30 kg/m2) older adults (\>60 yrs.) with mild to moderate functional impairment (by Short Physical Performance Battery; SPPB score \>/= 4)

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Weight Loss Control

Diet counseling and group education lessons. Subjects follow a calorie-reduction diet for a weight loss of ≥10%.

Group Type ACTIVE_COMPARATOR

Diet counseling and group education lessons

Intervention Type BEHAVIORAL

Individual and group diet counseling to achieve a \>10% weight loss

Weight Loss-High Protein

Protein supplementation. Subjects follow a calorie-reduction diet for a weight loss of ≥10%, with a high proportion of protein, including substantial amounts of supplemental protein provided as lean beef. Intakes of \> 30g of high quality protein will be achieved three times a day by subjects in this group, with all or predominantly all from animal source and 60-70% of animal protein from beef.

Group Type EXPERIMENTAL

Protein supplementation

Intervention Type DIETARY_SUPPLEMENT

\> 30g of high quality protein will be achieved three times a day by subjects in this group, with all or predominantly all from animal source and 60-70% of animal protein from beef.
