If you live with another person and don't want to throw out all your food, buy your food before you start. Buy fruits and vegis so that you will have food for your meals and snacks.
If it is not in your house how can you eat it?
Aim for 4+ servings a day of vegis and 3+ of fruit. If you must drink juice drink just a few ozs not the whole 8 ozs. And mix it with water. Tang is a good thing to keep in your house.
