That’s a pretty cynical question. My doctor advises a vegan diet for her diabetic patients, since it is very effective against type 2 diabetes. Patients who follow her advice are generally off their meds pretty quickly, and pay far fewer visits to my doctor.

Totally anecdotal, but it’s a datapoint that shows there are doctors who adopt profitless treatments if they truly are in the best interest of the patients.
