Doctors, nurses, scientists, lawyers have the lowest rates of obesity according to the cdc. Protective professionals, police, firemen, security guards, and prison protection, and truckers,  have the highest of all.  My personal experience in the hospital is that there are very few visibly overweight doctors, but I work in a large academic medical center with many young residents in training. Hospital pharmacists are almost all good looking and fit,  as are most PT and OT people. Nurses are a grab bag. Lots of older really fkn fat ones, but most young ones are not fat. Case managers are almost ALL huge planetary sized amorphous blobs of congealed oils.
