Hello! I would first and foremost discuss or consult your concerns/questions and goals with a professional health specialist, they will be able to to blood and tissue work to get you on the right path ...
That saying, my brother was once obese, and I swear he used every diet trick in the book, however, the one nutrition diet that worked for him and kept the weight off was the The ketogenic diet ( The Keto diet). It is similar to the atkins where it is very low carb, some would argue it's extreme for this very reason and you really have to monitor your diet intricately ( not recommended for people with Diabetes). My brother has such great success with this diet, now in his 40's, he the most healthiest and fit he has ever been in his life.
Again, talk to you doctor, there are various directions to take.

P.S. Plain filtered Water does wonders, I always like to have a fresh quart around me as much as possible.
Best wishes on your healthy journey,
