I can really relate to this thread, dad's an obese diabetic and mom has bad cholesterol... I've been LC'ing now for over a year and they have finally come to accept my WOE, and are very good about making LC meals when I come to visit. However, neither of them are willing to try it themselves. I have to accept their choices as they've accepted mine. It's hard not to proselytize though when it's your own family and you know it could help them so much!

My dad eats sweets too I think The biggest difference I've made to him is that he does it when I'm not looking now.
