2. Lower Your Weight. If you're overweight, you might not have to lose as much as you think to make a difference. In one study, people who had prediabetes and lost 5% to 7% of their body weight (just 10-14 pounds in someone who weights 200 pounds) cut their chances of getting diabetes by 58%.
Ideally, two to four hours before a workout, eat a meal that is rich in complex carbohydrates (think oatmeal or brown rice), moderate in lean protein (think chicken or low-fat and fat-free dairy foods), lower in fat (think nuts and oils) and fiber (think broccoli and cauliflower) and includes plenty of fluids (think water or low-calorie beverage).
Depending on how heavy a meal you have eaten, wait at least 30 minutes to two hours before exercising. The bigger the meal the longer you will need to wait. If you just eat a light snack such as pretzels or a fruit drink, you should be ready to work out within 30 minutes.If you exercise first thing in the morning, some fruit or a small amount of juice and water should suffice.ating a high-carbohydrate snack two hours before exercising can leave you ample energy and a calm stomach for a great workout. Many athletes avoid food within two hours of a very hard workout, but can tolerate a lighter snack within one to two hours of a light workout.
