NCT01715753

Brief Summary

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 Arms (2)

Weight Loss Control

ACTIVE COMPARATOR

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

Behavioral: Diet counseling and group education lessons

Weight Loss-High Protein

EXPERIMENTAL

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.

Dietary Supplement: Protein supplementation

Interventions

Protein supplementationDIETARY_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.

Weight Loss-High Protein

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