After-Dinner Workouts Best for Type 2
If you have type 2 diabetes, an after-dinner workout might be your best exercise bet. Researchers studied 13 obese men and women with type 2 diabetes on three different days: During one day, they performed resistance exercise (such as leg presses, shoulder raises, and crunches) before eating a high-carb spaghetti dinner. On another day, they did the same exercises 45 minutes after the same meal. Compared with blood glucose readings on an exercise-free day, blood glucose levels were 30 percent lower when the exercise was done after eating but just 18 percent lower when exercise came before eating. The after-dinner workout also reduced triglycerides (harmful fats in the blood), whereas exercising before had no effect.
