I can tell you a drug that works for weight loss. I use it for autoimmune issues. Low Dose Naltrexone. Doctors also prescribe it with Wellbutrin combined in a pill. I don’t take it that way. I chop up a 50 mg naltrexone pill to .5 doses or less. If you want it for autoimmune issues but can’t get the Rheumatologist to prescribe it you can ask for it for weight loss from a primary care physician
I cant say how it would interfere with diabetes but here is a good video on how it works

by the way, good thing I didn’t take any of the wellbutrin because it is heavily involved in the CYP2d6 P450 issues.
