It seems the bodies of the majority isn’t so very happy with their woe, though.
I don’t say keto is good for most people, I don’t know that (only that the opinion keto is the best for everyone is very biased and wrong) but overdoing carbs harmed me even when I had no idea low-carb is an option.
And it doesn’t matter who is the target. Too many articles talk about carbs being awesome and much fat being bad while it’s simply not true at all.
Sometimes one needs to eat more carbs though, indeed. At least this article talks about problems - not like adding carbs would be the only option but at least it doesn’t say I am an idiot to eat little carbs when I feel way better that way.
