I don't know what info you got, but it was disinformation.
I've lost 42 pounds since Jan 24 of this year. I eat meat, cheeses, eggs and lots of veggies and certain fruits. Works like a charm for me and I don't crave sweets anymore. My cardiologist does not have a problem with this diet.
BTW.......I DON'T need my Prevacid anymore because my heartburn also went away.......along with the added weight.
I started the south beach diet on Monday and it went well till today :). You get lots of cheese sticks, eggs for breakfast, and vegetables like celery and cukes. It's like a modified Atkins and also is developed by a cardiologist. Taught me that baked potatos don't SEEM bad for you, but they turn into sugar immediately.
