Adjusted BMR was 1,868 +/- 41 kcal/day in the control group, 1,445.57 +/- 76 in all PCOS women, 1,590 +/- 130 in PCOS women without IR and 1,116 +/- 106 in PCOS women with IR.   Insulin resistant PCOS females have a BMR about 700 calories lower than normal. That's about a 1.5 lb a week weight gain if you are following standard dietary calorie use charts. I have PCOS and didn't know this, I can garauntee most PCOS suffers won't know this. I wonder how that works? Lowered energy output through lower activity because they don't burn carbs properly, which lead to fatigue?  I can testify, my energy is crap on the odd occassions I backslide and eat carbs.
