Disturbia... The hardest thing about dieting is actually doing it for yourself.
Whenever I diet for a show I can do it... its hard as balls but I do it because I have to, and I can drop anywhere from 70-50 lbs in 4 months..
Whenever I try to diet for myself to look better, to be healthier, whatever it is, I always FAIL and FAIL hard! Even if its just 20 lbs LOL I can't ever diet in the off-season!
Something else I do when prepping for a show, I pay the the application fees as soon as I possibly can, and I tell every person in the world that would listen that I'm competing, all that adds to the motivation of staying on track!
I think setting a target, a legit target (not just saying... by this time I will weigh this much), makes a world of a difference. Have you thought about competing? Even as a novice... that maybe the solution to get you to reach your goals. how much weight do you actually need to lose?
