My sister/MOH is doing the herbalife shakes to lose weight before my wedding (completely her choice, I don't care what size she is). I want to lose the 20lbs I've gained in the last year, and she's been pushing for me to try herbalife. She doesn't sell it, she wants to give me some of her shake stuff. I've never tried anything like this before. I've always just ate right and worked out, but lately, I haven't been able to lose anything by doing that. I'm scared to get that kinda help to lose weight. Anyone tried it before? What are your thoughts on it?
