When there's two pieces of cheese left, I remind myself that if I eat only one, now, I'll have the other for later and I won't have to spend money on some other food at that time. The cheese is an example. I do this with desserts and other foods, too. Sometimes it works and I wait which saves money, other times temptation is great. Also, if weight is lost and clothes fit better then I won't need to buy that next size up.
