Dieting Beats Exercise for Diabetes Prevention, Combination Is Be
Lifestyle changes that include dieting to lose weight and exercise can help prevent type 2 diabetes, but researchers were uncertain which element contributes more. A new study suggests that, in postmenopausal women at least, dietary weight loss alone is effective while exercise alone is not effective, and both together are best of all.
“The effects seems to be additive,” said Caitlin Mason, Ph.D., lead study author. “The women who did both diet and exercise together had the greatest weight loss and greatest improvement in insulin and blood sugar control.” In light of the additional benefits of exercise, such as preserving muscle mass during weight loss, “a combined program is the way to go,” said Mason, a postdoctoral fellow in public health sciences at the Fred Hutchinson Cancer Research Center.
