After an operation the problems started: I need to detox and lose weight

I was operated on my spine and unfortunately the operation went badly, so I had a lot of pain for 10 years, they stuffed me with medicines, then I found the right doctor with the right therapy and I slowly got rid of the heaviest medicines that remain only those to sleep and painkillers finally at a very low dose, but I’m continuing to go down but it takes time. I have always had a very fast metabolism, but with all the medicines I have taken I have put on a lot of weight. I am 1.60 tall and weigh 58.5 kilos more weight is increasing because I have quit smoking, I need to detox and lose weight, you can give me the possibility to follow a very effective diet (with things that I can find however, because I tried some books and websites but they talked about foods that in a fairly small country I can’t find, I relied on the internet but many things were not even there) I love fruit and vegetables and I have a need (according to medical analyzes ) of protein because I eat too little meat). Can you give me recipes or a cookbook to follow or a program on which to base myself and be followed in some way? I am willing to pay to get back to my physical shape, because I am starting to skip meals, I no longer see myself in this body, I feel ugly and I am afraid you will also become psychological, I struggle to lose weight and the doctors are worried because having changed them (seen that the first ones just stuffed me with medicines without solving the problem) this new team also raises the problem of weight for a healthier life.
