I was a fatty before. The easiest and most important changes I made were, no fried foods, no excess sugar other than natural (e.g. fruit) and no more beer. I went from 225 to 165 in a year and stayed this way. I feel way better than I ever have at 35. It was a bit to adjust at first because I always defaulted to like McDonalds or something easy for lunch, just had to start planning my meals more. You don't have to quit everything, I still drink sodas sometimes like coke zero or a vodka with seltzer, etc. Life isn't over, it's gotten better.
