For me, I just brainwashed myself into seeing cookies, chips, pizza as poison. I also make sure that I am never hungry...thus I nosh all day long sometimes. Not having the temptations around also helps...kinda hard when you have kids like I do...but even my kids rarely eat carbs these days....and if they do its not in my home.

Its willpower...some have it...some don't...but everyone can attain it....its all mind over matter.
