The thing about extreme diets is that although they may get results, I'll never not think a bacon cheeseburger or cheesecake is delicious. So making these extreme changes can only last so long. Whenever I did shit like that, I'd get off the diet, or even just lighten it, and suddenly I was back to eating garbage. I feel like the key is to have a diverse diet that is mostly healthy, but has enough bad shit in it to keep that side of me satisfied. Also, although both matter, exercise gets better results than diets do. Sitting on my ass and eating healthy leaves me in worse shape than going out skating a lot and even drinking sugary drinks or eating an occasional burger.
