I tried the calorie cut for about a month between 1200 and 1600 a day...it was miserable! I worked out 30minutes a day Mon, Tues, Fri, Sat (Days not in school

). Plus I did silly things like hold my legs out at my desk during the day for as long as I could, I would walk down the steps from my office (once in the stairway the door would lock and you had to go to the ground level to get out) twice a day, park far from the door, take the long way around the office to the bathroom, etc. I mean no weight loss!! I would go down to maybe 159 and the next week I'd be 162 again. It is crazy. I try to make a 500calorie a day deficit every day which should = out to 1 lb lost per week but nothing! My hubby says I have metabolic resistance to weight loss and that I just have to keep trying different things until I find what works.
Any ideas? I've had thyroid tests and that is fine, I'm hypoglycemic so I don't eat sugar. I don't eat junk food. I eat lots of chicken (grilled), salad, small dinners usually just one item, no pasta or rice...lots of broccoli.
