Clean eating would be a good place to start. At the end of the day its how bad do you want it? Yes, there is a lot of awesome food out there but it all comes with a price.. To me and probably a lot of others on this board, its just not worth it down a pizza for 20 minutes only to hinder your goals. Start avoiding all refined processed carbs, and work about 40ish grams of fiber into your diet, black bleans are good for that, they will make you feel fuller on a smaller amount of calories, and give you a decent amount of protein too. Congrats on hitting the gym as much as you are but that will not do it alone as you know. There are some pretty good articles out there on clean eating, just search a list of clean foods and do some grocery shopping, and avoid eating out... in my experience its hard to eat healthy at restaurants. I wish the best for you !
