4 years post liver transplant/needing to lose weight/

Hello! I received a liver transplant in 2020 from a living donor , my daughter. Basically, have done extremely well. Did have colon resection a year ago. Completed a year of Evenity which is believed to have elevated my liver enzymes but is improving.
As of now , I need to lose weight. Transplant sent me to obesity clinic. Basically, the dr suggested surgery, protein drinks, phenterine or injections
and a 1000 calorie a day. The pills would not be good with high blood pressure. Surgery not appropriate. Basically, I’m trying to reduce sugar intake and eat more protein. I am trying to research the injection of Lipo Mino. It differs from the semiglutide which my transplant dr suggested. I worry about the side effects on that one. I welcome input ! I need to
Lose pounds to keep my donated liver healthy! Thank you !
