It's a bit of trial and error to see what works for you. I like to have a variety of textures and flavours eg. apple, peach, celery stick and carrot. I find if I have a bag of grapes open in the fridge at eye level, when I'm in one of those moods to pick I automatically eat a few grapes. This gives me time to realise, oops I'm picking, before I eat anything too devastating.
