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!!

How many calories are you getting?
Ketosis is characterized by a fruity quality to the breath, not a metallic flavor in your mouth. Ketosis is very easy to recognize, if you've ever been around a diabetic OR someone on Atkins/other low-carb diet. I think you would be wise to explore some other suggestions listed here.
Personally, I'm new to Paleo, and love it. I find that I am rarely hungry, and that it is easy to under-eat. I never thought I'd ever say "I under-eat quite often." Anyway, I totally follow how I feel regarding food consumption: some days I feel the need for more, but usually less.
Thanks for all your info & insights, fellow cave people :)
Metallic taste in the back of the mouth can also be due to bad pine nuts, heard about something known as "Pine Mouth" yesterday on NPR. http://www.epicurious.com/articlesguides/blogs/editor/2009/05/got-pine-mouth.html
In my family, and this is the only place I have observed this, we have a nasty taste on the back of our mouth when we are deficient in zinc.
My mom displays this most prominently, and when she takes high dose zinc for a while it goes away. I should mention she also drank mostly tap water for years in our copper piped house, so I suspect it may be a zinc/copper interaction.
Anyways, if you're curious there is a simple field test for zinc deficiency which is to put 'Zinc Tally' on your tongue and see if you taste the metal. If it tastes like plain water, you are likely deficient in zinc.
There are several possibilities.
The most likely is hypersensitivity. I found that the more I restricted my diet, the more occasional indulgences in previously tolerable foods hit me hard.
I would suggest trying an all meat restriction diet. Naturally this will create a serious cravings problem.
The solution, I find, is to eat a daily meal of ground beef with eggs in a ratio of 250 g beef to 1 egg.
I eat this with no salt or seasonings, keeping the eggs to a reasonable minimum, and it's the only thing that's cured my health problems (IBS and chronic fatigue complex).
It's most likely a nightshade allergy
According to Medline, common side-effects of calcitriol injections include weakness, headache, somnolence, nausea, vomiting, dry mouth, constipation, muscle pain, bone pain and metallic taste.4 Note the muscle and bone pain—do these sound like nightshade problems I’ve mentioned already? The liver and gall bladder can be affected, resulting in pale or fatty stools, an indication you are not digesting your fats well. Yellowing of skin or eyes (jaundice) is another symptom, indicative of liver issues. Hallucinations can happen, and a rare side effect is overt psychosis. Remember what was said to happen when one eats eggplant every day for a month?

It fits... Eliminate for a few weeks and let us know
Your symptoms match the experience my cousin had a while back - she was fortunate enough to have a dental appointment shortly after her symptoms started, and he diagnosed her with an uncommon infection that involved an imbalance of bacteria throughout her GI tract, impacting taste and digestion. I can't remember any more details (except that it was treated with antibiotics, to which I rolled my eyes wildly), but I would go to a GP or a dentist to see if it's an oral condition (easier to diagnose than more general GI tract problems).
If you can handle eating some fermented foods like sauerkraut, kefir, or even good yoghurt, that could be a good start to see if it's a bacteria issue.
Are you supplementing with Iodine (Iodoral, etc.)? That can leave you with a metallic taste.
Do you eat many nuts? I have noticed a similar bad taste when I eat anything that has almond proteins in it (I am okay with almond oil, but not roasted or raw almonds or almond milk; not even homemade almond milk). Leaves me with a burned, bitter taste on my tongue.
My husband develops this if he uses a lot of Tums, which are mostly calcium carbonate.
So, he stopped eating so many foods that give him heartburn, took Mg and Zinc, and it went away.
I'm suppose you're not using tums, but are you supplementing calcium?
Congrats on starting the journey! How about focusing on some in season soft skinned fruits for a while? Flax might help...try some flax/coconut baked good (lots of recipes online). How about some fish if you are struggling with the meat issue? Fish can be over fried with ground flax and spices with a bit of coconut oil on the pan. Give it a whirl...
