[Elf] How did Buddy survive on an elf diet?
gpt
While eating a lot of sugary foods can cause weight gain, Buddy seems to be extremely active and appears relatively fit. Diabetes is not actually caused by what you're eating so he should be okay in that regard.

His biggest issue would be cavities, but it appears that by the time Buddy was around Hermey had successfully instituted a good dental program at the North Pole.
