Dentist Tip: Brushing three times a day is ideal. If you can brush once after every mealâbreakfast, lunch, and dinnerâyou minimize the growth of bacteria in your mouth. But wait an hour after each meal: brushing too soon can cause damage to the enamel of your teeth.
Eat a Small Meal One to Three Hours Before Exercise. If your breakfast is a light, low-fat meal you can workout within one to three hours and get the benefit of the calories with less risk of stomach distress. Opt for a Carb Snack 30 to 90 Minutes Before Exercise. If you want to eat close to your workout time, focus on easily-digested carbohydrates for a quick fuel boost. Ideas for this snack include the classic banana, fruit juice, a low-fat bagel or English muffin, or low-fat yogurt. Energy Snacks for Walkers.
