Basal metabolic rate is decreased in women with polycystic ovary syndrome and biochemical hyperandrogenemia and is associated with insulin resistance.
OBJECTIVE: To evaluate basal metabolic rate (BMR) in women with PCOS and to determine its association with insulin resistance (IR).
CONCLUSION(S): Women with PCOS, particularly those with IR, present a significantly decreased BMR.
We're talking about a decrease in avg 280 +/-130 kcals per day for PCOS without IR (where the control group measureds 1868 +/- 41kcal per day) and PCOS with Insulin Resistance BMR doesn't just drop it plummets to 1116 +/- 106 kcal per day. There's also a greater variance swing for women with PCOS.
Am I totally grateful that I don't have IR as well as PCOS+androgen disorder.
But it does mean I need to heavily revise for myself what I understood to be a normal diet. Because what it means is that whenever I thought I had reduced the amount I was eating to slowly lose weight (approx 500 per day less) I was in fact barely reducing the amount needed due to having PCOS. (Undiagnosed until mid 40s, and the specialisist said I'd have had it since puberty). So not presenting with typical symptoms and referred pain equalled a decades delay in diagnosis. I'd get an aching near my right hip, but tests showed there was nothing wrong with my hip/area.
Ah well, making fresh start with increased knowledge. If I can reverse the 6.5kg gained in the past 12 months I'll be happy. If I can then reverse the gain since my gallbladder was removed I'll be even happier.
