Many diets today require you to purchase special foods for their diet. That can be good if you can convince your family they too need to eat this way but many times they flat out refuse!!! The one good piece of advice most diets recommend is to drink water. If you drink plain water instead of diet colas, diet powdered drinks, diet add to your water drinks, etc…they can add up to a small fortune. Just going to plain water with a slice of lemon, lime or orange is a cheap drink that is good for you and good for the wallet.
