Abstract Objectives Weight loss interventions for older adults often reduce bone mineral density (BMD), increasing risk of subsequent detrimental outcomes. This study explored the long-term impact of a higher protein diet plus exercise versus a diet plus exercise control treatment on body weight, bone mineral density at 3 sites, and fracture risk. Methods Obese (BMI 34.3 ± 4.7 kg/m2) older adults (n = 55; age = 70.0 ± 6.1 yrs) with Short Physical Performance Battery (SPPB) score = 9.2 ± 1.4 (out of 12) who completed a 6-month weight loss plus exercise trial were invited to return for assessment 12 months later. The original randomization was to either 0.8 g protein/kg body weight (Control) or 1.2 g protein/kg body weight, predominantly dairy (Protein). The 18-month assessment included BMD by DEXA (Hologic, Horizon model A) for femoral neck (FN), total hip (TH), and spine (lumbar vertebrae 1–4; LS), as well body weight and secondary outcomes for Fracture Risk Assessment Tool (FRAX). Results A total of 38 (69.1%) study completers were assessed at 18 mo. Body weight was lower than baseline for both Control and Protein (P < 0.01), with Control (−4.8%) trending towards better maintenance of weight loss vs Protein (−2.3%) (P = 0.06). BMD at 18 mo. was not different from baseline in both Control and Protein for LS (0.01 ± 0.05 g/cm2 and −0.0002 ± 0.05 g/cm2; P = 0.512), FN (−0.01 ± 0.07 g/cm2 and −.009 ± 0.04 g/cm2; P = 0.814) and TH (−0.012 ± 0.03 g/cm2 and −.008 ± 0.033 g/cm2; P = 0.685). Change in BMD at 18 mo. did not differ by group at any site; the previously reported Protein group increase in LS at 6 mo. was not sustained. For individual fracture risk, between 0 and 18 mo., 6 improved (5 osteopenia to normal, 1 osteoporosis to osteopenia) and 1 worsened (normal to osteopenia but FRAX score below total and hip fracture thresholds). Conclusions The finding that obese older adults can maintain a lower body weight for 12 months without a decline in BMD and no increase in fracture risk amplifies our previous findings of legacy benefits of a short term obesity intervention for older adults. Further study is needed to determine if the protein benefit to LS is sustained if the higher protein intake is continued long term.

This study examines the effects of weight loss by caloric restriction (WL) and aerobic exercise plus weight loss (AEx+WL) on total and regional bone mineral density (BMD) in older women. Healthy, postmenopausal women [age 63 ± 1 (SE) yr] not on hormone-replacement therapy underwent 6 mo of WL ( n = 15) consisting of dietary counseling one time per week with a caloric deficit (250–350 kcal/day) or AEx+WL ( n = 15) consisting of treadmill exercise three times per week in addition to the weight loss. Maximal aerobic capacity increased only in the AEx+WL group ( P < 0.001). Body weight, percent fat, and fat mass decreased similarly in both groups ( P < 0.005), with no changes in fat-free mass. Total body BMD (by dual-energy X-ray absorptiometry) decreased in both groups ( P < 0.05). Femoral neck, Ward’s triangle, and greater trochanter BMD decreased in the WL group ( P ≤ 0.05) but were not significantly different after AEx+WL. L2–L4BMD did not significantly change in either group. Thus WL and AEx+WL both result in losses of total body BMD; however, AEx+WL appears to prevent the loss in regional BMD seen with WL alone in healthy, older women. This suggests that the addition of exercise to weight-loss programs may reduce the risk for bone loss.
