My maintenance bmi seems to hover around 22.7something: 5'5" and 135-137 lbs. I started at 149 lbs and bmi of 24.83
My goal was to go from size 14 (US) back to size 12 that I had been for many years before the pounds started to creep on. I reached that goal at 139 lbs. and decided to go to 135 to make "a nice round number". I've been maintaining almost 2 years and find that sometimes I stay near 135 with no fasting week after week and other times I need to fast weekly to keep in range.
I'm 74 years old and use HRT (estrogen patch and progesterone capsule) I'm sure this must effect my weight and metabolism along with helping my mood, energy, skin and bone strength, etc.
We're all so different, aren't we?
