Comparing between the effect of energy restricted diet and yoga on the resting metabolic rate anthropometric indices and serum adipokine levels in overweight and obese staff women

Weight management is an important strategy to prevent the consequences of obesity. The aim of the study was to compare the effect of yoga practice and energy‑restricted diet on resting metabolic rate (RMR), anthropometric indices, and serum adiponectin and leptin in overweight and obese women.

Obese or overweight women were divided into two groups: yoga practicing and energy‑restricted diet. Exercise trials consisted of 60‑min Hatha yoga equal to 200 kilocalories (kcal) combined with 300 kcal restriction per day, and an energy‑restricted diet consisted of 500 kcal restriction per day. The intervention period for both the groups was 8 weeks. RMR, anthropometric indices, and serum adiponectin, leptin, and lipid profiles were measured at baseline and at the end of the study.

RMR was increased in yoga but not in the diet group (P = 0.001). The level of adiponectin was increased in the yoga group compared with the diet (P = 0.035). The concentration of high‑density lipoprotein‑cholesterol was decreased in the diet group significantly but not in yoga (P = 0.006). The level of leptin was decreased in both the groups (P = 0.001), and there were no significant differences between the two groups.

The findings of the study demonstrated the effect of yoga practicing on RMR, and serum adiponectin, in overweight and obese women. It seems yoga practice with less energy restriction compared with a common energy restriction diet and is more effective in weight management for those who are in weight loss programs.
