I'm a middle aged male that found themslevs totally out of control at over 400 lbs. I'm not even sure how much over 400 I was, because the scale wouldn't return a number. Now there is a wake up call!!! I started getting serious January 2015, when the scale would actually register at 390. Set a goal of 2.5 lbs per week, and have been doing my dead level best to stay on track without getting stupid. My diet is basicly a replacement diet, I eat a healthy diet at around 14-1500 cal a day. Then I allow myself to eat as much above that as I want, as long as it is fresh fruit/veg. Working for me so far, the good part is not being hungry, but cravings can still be a bitch.
