It's not truly scientific to be changing a lot of factors at once, but I've decided to stop the true fasting over 12 hrs and re-introduce some foods, viz. fruit. I just feel that a true fast over the day doesn't work well for me re fat loss and LBM-maintenance. OTOH, the LBM-loss might be simply water loss which may indicate that I'm having less inflammation problems.
By only adding fruit I'll go in-between a true fast and eating. At least that's how I'm justifying this move.
I'm simply not happy with the drop in maintenance, even though apparently this is a maintenance that is normal for women my age and height (I'm 43 y.o. and 1,59m tall/short) working out every other day but otherwise having a sedentary job with only some walking.
Contrarian and anti-KISS!
diet: back to 3 square meals but skipping lunch = 2 short fasts.
