In April 2010 having reached 206lbs (16st 2lb) I decided to get into losing weight especially as I have a bad back. I lost 30lbs that year and had a wee break over the Xmas hols. January 2011 I got back on the wagon and continued with my 1200 calorie diet but found that my weight just would not shift. I then changed to 1000 cals, then 800 cals for a few weeks and have also tried doing low carbs but with absolutely no loss at all... if I do manage to lose a pound or two it will then go back on again after a few days no matter how I try.
Being on Co-codamol and Naproxen for my pain and having an under active thyroid for which I take 150micgrs of Thyroxine per day, I do feel that this may well have a great deal to do with this problem.
Any suggestions PLEASE!!
Take a break. Up your calorie intake to your BMR for a week, and only do light work outs (I suggest walking). Then cut back down to your 1200 kcal diet (net kcals! you have to factor in kcals burned!) and make sure you're getting a gallon of water a day and plenty of sleep.
If you drop your calories too low your body will start to conserve energy by slowing down the metabolism because it is starving at that point. Its not simply calories in/calories out. The body is more complex than a furnace. Get all your hormones checked as well. Not just sex hormones, but thyroid, insulin, etc. if these are out of whack. It makes it harder to lose weight
