Why do I keep smelling melted butter?

[StrongNose44]

This mystery has been plaguing me for over a year. It seems to coincide with when I transition back into the LCHF diet. It makes me think it must be related to metabolic processes in some way, but I can't seem to find any literature about it. It's so weird! I'm the only one who can smell this mystery butter, and I smell it all day long. It's as if someone rubbed butter in my nose! It's been over 24 hours since I've consumed butter, and it was a small amount with a fried egg for breakfast. If anyone has access to medical literature and could look this up, I would be most grateful.
Thanks!

Did you ever find out what was causing it? I get it too.

There is something called phantom smell.  You should see your doctor because it can be a warning sign of other issues.  https://www.nbcnews.com/health/health-news/phantom-smells-may-be-sign-trouble-n890271

I mentioned this to 2 physicians, neither seemed concerned.

Me too! I have been shifting towards the whole30 diet... I always smell butter as soon as I get to work and all day at work.  I work in a hospital. It has to be related to my diet.
