I have been following a Paleo diet for 5 months now, and in the last week I have had an awful, metallic taste in my mouth, accompanied by hypersensitive taste in general. I have been pretty low carb the whole time, so I can't imagine that I am going into ketosis for the first time now (and I even had root vegetables for the first time right before this started, and rice noodles yesterday, so not so low carb this week). It happens all throughout the day, sometimes hitting in the middle of a meal, but it's always there when I wake in the morning.
I have also had waves of nausea, and (most disturbing) a complete aversion to meat and green veggies (pretty much all I eat). I thought that I must be pregnant, but every test, including the most sensitive blood test, have come back negative. It is starting to be a big deal; I ate rice noodles yesterday and felt awful afterwards, only because I am having such a hard time finding things to eat that don't taste gross/make me nauseas.
Any ideas would be greatly appreciated!!
