I don't even mention what I'm eating. If I'm eating out with others I order a salad like Cobb or Chefs and an appropriate dressing and let it go at that. The only people I've told about this are my sis and my daughters. It was my sis that convinced me that it works. I was doubtful when she said she was doing it but she's at 130 and looks wonderful. One of my daughters is on it and doing great though she had only a few pounds to lose.
When I go to the potlucks I take a meat dish and then have some of that and some green salad. Nobody even notices. If I don't eat dessert, well, "I'm full already."
