Hello' I'm matthew and I'm from Australia. I'm 25 years old and currently weight around 98-99 kgs. My weight target is 85 kgs. I started to rapidly gain weight a while after I started taking olanzapine 5mg medication but once i got to about 100 kgs it stabilized. Now I want to try and lose weight but not sure exactly what to do, I was drinking alcohol for ages everyday until just about 2 days ago.

I do Karate once a week for 60 minutes, i only really eat breakfast and lunch and sometimes a snack like chips, sandwich, etc. So what should I do? oh btw giving up the olanzapine is not an option.
