I'm also new to this site - and looking for an on-line group for support. I am following the concepts of IP without the purchase of the food. I have an underactive thyroid so find it extremely difficult to lose weight. I did great my first month on this new plan (Feb, 2014) and lost 8lbs and 7 inches. I'm only 5 feet tall and would like to lose 40-45lbs. I weighed today and was up 2lbs - totally deflated me but I know this plan is the only way I can lose the weight. I have tried many diets with only a small amount of weight lost, and then I lose interest and motivation. I am interested in hearing if anyone else has struggles with the IP protocol and hypothyroidism. Is it more of a slow process if you have thyroid issues? It seems other people I have read about are losing more each week than I am. May be it has to do with the amount I need to lose? I would appreciate any feedback. Thanks!
