Try to find a balance... little bit of all the good stuff. Meat, fish, dairy, gains, vegetables and fruits. Well, all of the things you can eat out of those groups. Get myfitnesspal and have a look at how it breaks down nutrition/calories/macros. Use it for a week to just put in what you eat, not to make adjustments. Just a week to get a snapshot of your diet. Once I got food sorted out I feel loads better. Down 14 pounds and I eat like 6 times a day
