most of my weight i had lost in the first year, i still fluctuate though. i haven't had to exercise really, the only reason would be to tone up. As far as appetite, you do get some back but you want to be careful to not overdue it. it does take time to get to know your limits. its not as easy as you think but you will get to know and adjust to the lifestyle. it is so totally worth it though. i wouldn't take it back dot anything in the world. good luck to you all and let me know how you guys do! Im excited for you all.
