I found this fascinating. I was just reading about aldehydes in “The Big Fat Surprise.” I’m not a chemist, but there seems to be some connection between naturally occurring body ketones causing a fruity smell, and the other ketone bodies.
Any chemists out there that can explain this further? Also, people have been asking me what fragrance I have been wearing lately. (I haven’t.)
After my morning work out, I smell like beef. I do shower shortly afterwards. And my smell returns to my normal sort of sweet pork kinda of smell. Have been eating a carnivore diet for 14 weeks and more.
There may be some acetone being exhaled on your breath. That gives a type of fruity smell.
From what little I’ve read about nasal scent receptors, quite disparate molecules can apparently smell similar; they don’t have to be chemically related. (And conversely, I would suspect that chemically related molecules could possibly smell quite different.) The key is whether the molecule in question has a structural group that fits the receptor and triggers it; and any molecule containing that structural group can latch onto that receptor, regardless of what the rest of the molecule is like.
