I prepare 90% of my meals. the most important thing i have to keep track of is portion size when im eating out. at home i dont have any large plates. the only large dishes are for hosting dinners. i try to fit all the food im eating in one hand... an 8oz piece of lean meat, a pile of cooked veggies and i complete whatever room is left with a moderate amount of carbs. never keep anything at home that doesnt require preparation
