Well I got my op on 4 January. Started my pre-op diet on 21 dec. I was 132kg
I got operated on 4 Jan. On 21 January I was 118kg. Lost 14kg in 1 month from pre-op.
21 Feb, i was 111kg
21 march, I was 108kg
21 April I am 104kg.
So it was a massive loss at first, but now down to losing 3 or 4kg per month.
