I didn't become a physician, because my teenage-self unpacked being a physician as telling fat people to eat better food and start exercising -- for 50 years. Turns out there are other specialties... Despite thinking the human body is fascinating, I'm largely happy I don't have to tell unhealthy people to do what they probably already know they should do and then give them a bandaid for their gaping lifestyle problems.
They’re not even allowed to do that any more despite it being a legitimate medical risk (top 5 reasons for death according to the CDC are related to obesity).
