My boyfriend recently started the ketogenic diet about 3 weeks ago and I have started noticing that his breath has been getting stronger and stronger.
It smells like a cross between the purple Listerine and the smell you get when you have a cavity. I read that his body is producing keto bodies - hence the smell.
I also read that it should smell like acetone but this smell is stronger and off-putting/ He brushes regularly now but the odor is still there.
Can anyone explain to me what is going on, if they have had any experience with this, what they did, or suggest what I can do to alleviate the situation or tell him to him so he can do something about it. I will also appreciate if someone can explain the science behind it.
