If you are eating at least 5 times a day as directed and you get hungry in between, you may need to add a snack. This depends on how many hours you’re awake and active plus other factors. Many people find that it is ideal to eat every 2.5 hours. Make sure you give your body at least 2 hours and no more than 4 hours. For example- Breakfast at 8am, Snack at 10am, Lunch at Noon, Snack at 2:30, Snack at 5pm, Dinner at 7:30 and Bedtime is 10pm.
