I guess there are quite a few methods that can help, some of them are better and some less. I can tell you what worked for me. One of the things that helped me the most was to start getting in shape, but fitness in the full term of the word. I hired a personal trainer who is also a nutritionist and he built me an organized and orderly menu, I had to take pictures of everything I eat for him and that's how I also felt uncomfortable "sinning" and eating things I shouldn't. This combined with 4 physical trainings a week brought beautiful results and quite quickly. I lost almost 30 kg in weight. There's still a way to go but I'm not giving up. I also know about various bariatric surgeries but their complications and the possibility that they won't work and I'll stay fat scared me, so I preferred to go for the more classic method. What have you already tried? What methods were you thinking about?
