I really wish to know why those people were on low carbohydrate diet though. It seems to me that most people don't do that without a good reason.
Even if this ends up with higher mortality (which I highly doubt this claim, there is a lot of research and results it is in conflict with) - I'd rather live feeling like this than the alternative.
I also question the meat claims because there is also a lot of evidence to the contrary. It seems like there may be a confounding variable in there that is skewing the results.
They weren't. It looks like the lowest in the study was ~20%, which is about the upper bound on what could be considered "low carb".
