What is the best weight loss diet for my case?

Dr please help me went to an endocrinologist and she was very thick with me said "you should be ashamed first to then think about slimming" I was shocked at her words. I had cardiac surgery (CIA) and I had to take many vitamins because I had difficulty recovering and I went from 95kg to 104kg today, I spent 8 months of surgery and I did not lose weight. I'm desperate because my dream is to weigh 70kg what diet would be better?
Expert answer:

The best diet for you is one that has been specially prepared for you by a nutritionist and it is always important to have your cardiologist's approval, but in this case I believe he will support you, it is really important that you lose weight.
