What did you snack on? I can do without bananas but I really like apples.
Now I snack on all kinds of stuff, including M&M's....but when I was dieting I kept to this stuff. I ate every 3 hours and made sure there was protein at every "feeding".
Nuts...primarily cashews, pecans. sometimes peanuts
Cheese...the real stuff, not Velveeta
Breyer's ice cream bars that are carb smart.
Cottage cheese...the real stuff, small curd, with pepper & chives or cilantro. or with fresh blueberries
Yogurt....Greek or the carb-smart stuff. I get it at Kroger's and it's Kroger brand.
Cantelope
Pepperoni or some type of deli meat
