Are snacks necessary? No. Simply ask yourself this question. Are you really hungry or just bored? Keep snacks completely out of sight. If you have a snack habit, replace that habit loop with one that is less destructive to your health. Perhaps a cup of green tea in the afternoon should be your new habit. There’s a simple answer to the question of what to eat at snack time. Nothing. Don’t eat snacks. Period. Simplify your life.
