I need tips for losing healthy weight

Hello guys, I gained like almost 20 kilos in last five years of being on meds. Every year I went up several cup sizes. I get really bad hunger urges on antipsychotics. I try to go to sleep after I take them but in the morning I am genuinely insatiable. It’s probably cause I am on the highest dose of antipsychotics and I have recently started antidepressants. Honestly I am very happy and mentally stable currently, I am just very round as well lol. I especially love binging sweets.
