What not to eat when you want to have a six pack abs?

The main thing is not to eat foods high in sugar or fat such as chocolate, chips, cheese and crisps as this just build up as fat and not muscle. Instead eat food high in protein as this will help repair and build up the muscles after a workout. Egg is high in protein (this is why some people drink a glass of egg for breakfast) as well as red meats and fish. Basically just any protein rich foods. Hopefully you're not a vegetarian!
