I was 64kg before I was on Olanzapine full time. Two years later I was 98kg.
Been on Latuda for two years, and I stayed at 98kg. However the last few months I am now down to 86kg by eating healthy and everything I eat I halve what I would have had normally. I try to only have a maximum of 1,200 calories per day where possible.
I am aiming to get down to 75kg, but I want to do it gradually. I need to try and exercise but was supposed to start for 2017, but not got to it yet :-/
