Hi there!
Well, I am lucky, in a way, to not have a family to feed. I'm doing this SB thing for just me and a very understanding boyfriend who has (at least at home and when we go out to dinner) changed his diet to accomodate mine. I do know, however, how it feels to start over on SB.
Briefly, I lost 35 lbs. in 3 months on SB in early 2001. I kept the weight off for about a year and slowly, let it all creep back, and then some. When I was 50 lbs lighter, I thought I still needed to lose weight and didn't fully appreciate what I'd accomplished. That was a mistake! Oh, if I knew then what I know now, right?
Anyway, the amazing thing is, even though a couple of years have passed, shopping, reading labels, and preparing healthy food all came back to me like I'd never stopped. I feel so comfortable and happy with my food choices now. Of course all the overeating and eating whatever the **** I wanted to between then and now left me feeling pretty empty, down on myself and emotionally downtrodden. It's like a breath of fresh air to allow myself to eat healthy and take care of me. I guess my point is, it's like riding a bicycle.
Advice I've received from other SBers is to buy the latest edition of the book and re-read it. There are some changes from the old edition, plus it's in paperback now. I have done that. I've been back to this WOE for two weeks tomorrow, and I've lost 8 lbs. (I know it's water, who are we kidding? but I'll take what I can get!)
I'm sorry I can't help with the issue about feeding your family. Try not to think about it as "punishment" when you don't eat certain things that your family eats. You're definitely rewarding yourself when you make the healthiest choice for you. Best of luck to you!
