Does weighted vest use during weight loss influence long-term weight loss maintenance? A pilot study in older adults living with obesity and osteoarthritis
Authors' conclusion
Pilot data signal weighted vest use during caloric restriction may be associated with reduced weight regain via preserved RMR.
Study context
- Population
- Older adults with obesity (70.4 ± 3.1 years, 83% women, 78% white) who completed a 6-month weight loss (WL) intervention and returned for 24-month follow-upconvenience sample
- Participants
- 18 adults
- Comparison
- Caloric restriction plus weighted vest vs caloric restriction only
- WL+VESTn = 9
- WL Onlyn = 9reference
- Outcome
- Weight regain after intentional WL (BW change from baseline)
- Follow-up
- 24 months
