My fucking doctor (internal medicine) said the same shit. My BMI is 18.5, so I realize I'm on the lower end but literally this is the only doctor that ever says anything, and she said the same when I had a 19.5 BMI. Infact, she's always complained and the "healthy" range has always varied depending on who I see that visit. I see them once a month, every month, for over 3 years so I've just kinda given up at this point, I let them talk and just nod along. It's like "Thanks, but I've seen your weighting teehee room, so I think you've been a bit desensitized to obesity..." Other doctors? "You're in the healthy range, and I don't get to say that often." Yea, I know unfortunately.  Also, guess which doctors office is incompetent? Like charge me cash and bill my insurance for the same visit, incompetent.. (yes, I absolutely deal with this when it happens but still)
