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).
If running on empty doesn't feel good to you, you will want to hydrate with water and eat something light that digests easily. A good pre-run breakfast for those who run three to six miles can be something as simple as a banana, water and maybe a cup of coffee an hour or so before starting your workout. You could also eat toast with jam or half of a carbohydrate bar, if that works for you.
