i hope your father in law is alright man.
as far as diet goes ive been going pretty clean food wise for just over a year. if you really have any problems wth junk food, suggest working at mcdonalds for a while or jsut eating there for all three of your meals for a week or two. i worked there for a year and becuase of money was eatng there a lot. when i finally switched over to healthy food, it felt like ecstasy.
im not a vege/pesca/lacto/ovo anything, but i do keep as healthy as i can. i used to be a sucker for soda so to cut it down i allow myself friday lunch with my best friend where treat myself to a 600ml coke. its somethng to look forward to. t boosts my sugar levels just that bit after a long week and it washes down the super healthy wrap that i have with it.
i think it really is all meant to be balanced. sometimes i walk through the supermarket and jsut breath in deeply, and kind of ask my body what it wants. if it wants fruit ill usually be getting the one that it wants at the time. makes me feel great and i have no problem keepng to it.
