摘要

The purpose of this study was to explore whether and how gravitational loading during intentional weight loss (WL) influences subsequent weight regain. Pilot data come from a convenience sample of 18 older adults (70.4 ± 3.1 years, 83% women, 78% white) with obesity who participated in a 6-month WL intervention and also returned for 24-month follow-up assessment. Participants were originally assigned to 6-months of caloric restriction plus 10 h/day weighted vest use (WL+VEST; n = 9) or caloric restriction only (WL Only; n = 9). Body weight (BW) and resting metabolic rate (RMR) were collected at baseline, 6, and 24 months. WL+VEST and WL Only participants lost significant and similar amounts of BW by 6-months [WL+VEST: –11.2 kg (95% CI: −14.6, −7.7) versus WL Only: –10.3 kg (95% CI: −13.7, −6.8)]; p = 0.71. By 24-months, the WL+VEST group regained approximately half of lost BW [−4.8 kg from baseline (95% CI: −9.6, 0.1)], while the WL Only group regained all lost BW [+0.9 kg from baseline (95% CI: −3.9, 5.8)]; p = 0.10. Change in RMR from baseline to 6 months was −16.3 (95% CI: –100.8, 68.2) kcal/day and −237.5 (95% CI: −321.9, −153.0) kcal/day for the WL+VEST and WL Only groups, respectively (p < 0.01); and was modestly and inversely associated with change in BW from 6 to 24 months (r = −0.39, p = 0.11). Pilot data signal weighted vest use during caloric restriction may be associated with reduced weight regain via preserved RMR.
