Review the snacks you keep on hand around the house and at work. Do they help or harm your overall health goals?
I've learned that if there aren't any corn chips or soft drinks in the house and I am limited to lower fat & less sugary snacks – like fresh baby carrots, baked blue corn tortilla chips, apples, and soda water – I am just as happy and have a lot more energy.
Don't torture yourself by keeping a bunch of stuff around that you don't actually want yourself to eat. Make it easy to snack well.
