lindora?

So, when I was in high school, I weighed 175lbs. Since my grandma passed a few years ago, I've gained weight and now weigh in at 245. I've tried working out but I can never seem to keep it up. I am pre diabetic now. My boyfriend is no help either, we even bought a bench press set and he promised me he would work out with me but we've had it for 3 years and he's only worked out twice(only to show off to his friends) and he eats like crap. Junk food/greasy food all the time. I over heard his doctor(who he hasn't seen in 5 years) say that he has high cholesterol and something is going on with his liver. He told him to cut down on alcohol(he doesn't drink) so then he says greasy foods. He wants him to start eating healthier and exercise. anyway my point is, if he sees me lose weight without him then maybe he will start, so I was looking at Lindora...I need a support group. What do you think of lindora? Have you tried it? Does it work? How expensive will it be? Is it worth it?
