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).
Always eat within 45 minutes of finishing your workout. This meal or snack is the only one of the day that should not contain much fat and should be higher in carbohydrates. For example, have a smoothie made with juice, fruit, and protein powder, but no flaxseeds or oil. Never do your weight training on an empty stomach.
