Interesting reports of individuals turning their life upside down. Just don't understand how they account for confounders and seem to make carbs responsible for everything that went wrong before their transition. But since sometimes it's those individual reports that get people to take action, I don't judge, happy for everyone taking charge of their health.

There are many factors driving weigth loss or gain, the macronutrients per se seem to be irrelevant in the long term though: https://pubmed.ncbi.nlm.nih.gov/19246357/

There are health risks involved in low/no carb diets and the article mentions none of those.

Too much carbohydrate creates issues, but I think the real culprit is sugar. The science is pretty solid there. Refined sugar can border on toxic.

Close behind sugar would be heavily processed carbohydrates like white bleached flour, etc., which are not that much better.

But there are of course confounding factors. There are people who eat more of this stuff and are healthy, but they seem to get a lot of exercise. That probably helps in multiple ways including burning up extra sugar quickly.

I'd hypothesize that high carb and especially high sugar diets are really unhealthy when coupled with a more sedentary lifestyle.
