Hi, I've been away for a while but need some help. I was sleeved on 11/14/13 and initally lost 65 lbs and never got to my goal of 160. I remained at 195 for almost a year and am now creeping up ever so slowly and feel awful. I'm at 202 today. I despertedly want to get to goal and start losing again but I'm at a loss as to where to start. I can still 2 1/2 years out eat very little, only 3 oz of pure Protein at a time. I don't eat serious junk but find myself picking. I am thinking it is a combination of things, I don't think I eat enough (I'm about 700 cals most days), I don't exercise and fear my metabolism is shot. I'm still drink Protein shakes 2 a day. Has anyone out there been in a similar situation? How do I start the weight loss again? Is the 5:2 something to consider? Looking for any and all advice. Thanks in advance.
