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).
What you eat 30 to 60 minutes before a run can dictate your performance; thus, it's important to make wise, healthy pre-run food choices. When training for a race, it's important to eat before your long runs (those that last more than an hour) and any key workout, such as hill repeats, a tempo run or a track workout.
