Pre-packaged foods are not that good for you. Loaded with salts and MSG's.

Ditch the processed cheese. Fat free doesn't mean it's better. It usually means it's replaced with chemical/artificial foods instead. Ditch cheese altogther if you want to lose weight.

Try oatmeal for breakfast. Drink more water. Eat fruits and salads, and if you want meat, buy it fresh or packaged as a whole, like ground beef for example. Avoid the pre-packaged sandwich meats and quick dinners.

Buy a LB of ground beef, fry it up and make spaggetti.

If you want sandwich meat, buy it from the deli section fresh and ask them to slice it up. Not the stuff vaccuum sealed in plastic.
