When to eat your snack is up to you, but you should keep in mind two things. First, the snack is more of a mini-meal, and like any other Thrive365 meal, you should eat it at one sitting. Second, the timing of when to eat is balanced out with your dinner – if you expect that you will have a late dinner, then have an afternoon snack. If you expect to have an early dinner, then eat your snack about an hour before you go to bed. All of this will help you to manage your blood glucose levels.
