Weight loss by diet reduces muscle strength

Diet-induced weight loss results in a significant reduction in knee extensor strength in overweight or obese adults, this systematic review of 27 included papers and meta-analysis finds. In the meta-analysis, knee-extensor strength fell by 7.5% compared with baseline levels (p < 0.001). An observed decrease in hand-grip strength was not statistically significant. Weight training or other physical exercise should accompany weight loss by diet.
