1. Snacking will NOT ruin your appetite.
Don't deprive yourself when you're hungry. "[Snacking] keeps blood sugar stable" and keeps you from getting too hungry between meals, says Debra Waterhouse, RD, author of Outsmarting the Mother-Daughter Food Trap. Dietitian Constance Brown-Riggs, RD adds you should go no longer than four hours without eating something.
2. You’ll get cramps if you eat before working out.
Eating 30 to 60 minutes before exercising will maximize your workout because it will give you a quick boost of energy. Opt for high-carbohydrate, low-fat, low-fiber snacks with moderate amounts of protein in the 100- to 300-calorie range, such as a glass of chocolate milk, a slice of toast with peanut butter, or a granola bar.
3. Even if you’re running late, eat a quick breakfast.
Eat slowly and take breaks in between bites. "It takes 20 minutes for the brain to register that you feel full," Brown-Riggs says. "If you eat too quickly, you can scarf down a lot of food in a 20-minute period, and then you'll feel stuffed."
