Exercise plus weight loss may make your insulin more effective.
Scientists randomly assigned 163 sedentary overweight or obese people to do aerobic exercise at high or moderate intensity. (They used a treadmill, Stair Master, elliptical trainer, or stationary bike.) The people weren’t told to change their diets.
After 8 months, insulin sensitivity improved in those who lost at least 3 percent of their starting weight than in those who lost less. Nearly one out of four participants lost at least that much weight.
Insulin sensitivity improved the most in the group that did moderate-intensity exercise: the equivalent of walking about 12 miles a week at a brisk pace.
What to do: Get moving.
