Weight-Loss Surgery May Improve Strength And Mobility
Researchers recruited 47 obese middle-aged adults, 40 percent of whom had diabetes, and tested their physical performance three times: before gastric bypass surgery, six months after, and at the 12-month mark. The participants, who shed an average of 66 percent of their excess body weight, lost some muscle mass but became 32 percent stronger, on average, relative to their new body mass index (BMI, a ratio of weight to height used to estimate how close a person is to a healthy weight). In other words, they became much stronger for their size. They also walked and stood up from sitting substantially faster than they had before surgery. If you’re obese, the option of weight-loss surgery may help you more easily carry out everyday activities.
