Don't know what to snack on? First, i'll give you this link to Livestrong. The site is great for keeping track of what you eat. Eating snacks between main meals is highly reccommended, so dont be afraid of opening the doors of your fridge 3 hours after you ate. Snacking can often be tricky because we don't really know what to look for when checking our pantries and fridges. You shouldn't snack on stuff you just found on your fridge or pantry, since it can lead to making poor choices. When going for a bite to eat, you should have predetermined foods that fit your diet.
