Usually what happens is that my initial weight loss will be
great at the beginning of the month, but will become more gradual
as my body burns all the glycogen and switches to fat burning.
I remember ten years ago back when I was in the Army during the
fasting month. I lost 3kg in the first three days..... and another
3 kg in the next 27 days.
I don't expect such a drastic weight loss this time round. But
that said, I believe a 4-5 kg loss is a possible outcome.
