I hear it all the time. I can't (my least favorite 'phrase')...stop eating. I can't stop eating sweets. I can't stop eating the fresh bread they give you at the restaurant. I can't, I can't, I can't...No wonder you think that to change is but a dream. Of course you can!!
How can one change? Focus all of your energy, not on fighting the old, but on building the new. Stop hating your body, stop thinking about your old and current habits. TRY something new, something different. Starting right now!
