Want to be smaller

Hi! I saw a few posts on here where people have had weight loss surgery and their BMIs are less than 35. I cannot find a doctor who will perform any type of procedure on me because my BMI is 33. I go to the gym and I eat fairly healthy, I just need a little extra help. I don’t want to take pills. I just want to eat less. I live in the Northeast part of the US, so finding a doctor should, in theory, be easy. But it’s not. Could someone please send me some info on a doc or program who will help me? Thanks!!
