It's a choice. If you really want to make the decision to go forward, you adapt to your surroundings.

I have 5 kids (who are all thin), who still eat the same stuff they ate before. I made the choice to say it was time to take care of my situation and I don't expect them to eat the same stuff as I do and vice-versa. I have noticed that their carb intake has decreased, and I think it has alot to do with a new attitude that they see me (and my wife) with. But if they want fries with their burger, or a bowl of spaghetti, we cook it for them. We then proceed to eat the things we're supposed to. If this is for the rest of my life, and not just while I'm dropping some weight, I might as well get used to eating stuff that may differ from those around me. After years of poor dicipline that left me 150 lbs. overweight, it's time to get past the point of using others as a crutch for my own lack of control.
