The suggestions "ktstato" gave you are good ones. You don't have to follow the Sample Menus precisely, and you don't have to spend a lot of money.
Look at the Menus, however, to get an idea of how to distribute your calories and fat throughout the day. Then be sure you have three meals and one or two snacks.
You might put almonds in your oatmeal or over cold cereal to bring up the fat in you meal, if needed, and a grilled cheese sandwich could be an easy breasfast.
Make some hard cooked eggs and have one or two with some yogurt and fruit fro breakfast. You might also take a loks through this Breakfast Message, and scroll down further, to get other ideas.
I hope this helps.
