When it comes to reading diet books, always look for what the books have in common. If you focus on what they have different, it will drive you crazy. Many diet books agree on a bunch of the same basic principles. Usually number one is to focus on protein. Protein will keep you full. If you get in the protein, you’re less likely to eat the bad stuff. Then, eat colorful veggies at every meal. More veggies equals less room for crap. Plus they are tasty when you give them a chance and cook them right. Finally, drink a ton of water. Keeping yourself hydrated is one of the easiest changes you can make to stay healthy.
