Annie, the best decision I've made...obese all my life, tried every diet known (some worked) and so far -- I'm 4 months out -- have the tool finally that has allowed me to lose the weight! So far, I'm about half-way to goal and have lost 80 lbs. eating is definitely different - I can't eat anywhere near as much as I did - thus the tool I mentioned. Check everything out,research!! Make your decision that's good for you. For me, I would do it again in a New York minute! Good luck, this is quite the journey
