Question: Why would I develop shortness of breath on a carnivore diet? That can happen in scurvy. So given that vitamin C is one of the higher-risk nutrients on a carnivore diet, that would be the first thing that I would look at. I'm glad it was short-lived. I think it's possible that there are vitamin C-sparing effects of a carnivore diet, but they take a little while to kick in. So as you transition, you had a temporary scurvy and then you had adaptations that mitigated that. Certainly it could be many other things, but without doubt, I would look at vitamin C first and given that it was short-lived, I think that's great. But I think that you should still do some nutritional testing to make sure that you're not in a marginal position on some of those possible things.  This Q&A can also be found as part of a much longer episode, here.
