Although health, environmental, and ethical concerns do have an impact on my dietary choices the truth is that I eat mostly for pleasure. Low carbohydrate diets aren't really my thing as I simply love good bread, pasta, and rice as well as good beer too much to consider giving them up or drastically reducing my consumption. I am, however, almost entirely live and let live regarding other people's dietary preferences and I have noted that there seems to be a substantial following here for keto and other low carbohydrate diets. I recently ran across this 2018 paper from The Lancet which is one of the most comprehensive analyses I've seen. The usual caveats apply regarding methodology (dietary questionnaires have not insignificant limitations) and that individual responses to a given diet may lie outside of statistical averages apply but I thought it might be of community interest.
