Yes, there are hundreds, probably thousands of articles on the keto diet by this point. One thing to realize is that the keto diet is an "all or nothing" kind of diet.
Those ratios (e.g., only around 5% of calories as carbs, 20% as protein, and a whopping 75% of calories as fats/oils) are carefully designed to PUT YOU INTO KETOSIS after a number of days or weeks.
If you don't achieve or else fall out of ketosis -- because of 1) how you eat; and 2) your particular genetic makeup -- then the body won't be properly producing and/or burning the ketones.
That's why this diet was rated DEAD LAST in the 2018 US News & World Report analysis of 40 different diets. Curiously, for all the talk about keto diets being good for diabetics, it scored very poorly in the rankings for 1) diabetes health; 2) heart health; and 3) longterm weight loss.
The vegan diet scored in the top 3-5 positions on all three of those parameters. (Yet the analysts only rated that diet #19 because of obvious restrictions on what you can eat and "lack of social support". For many vegans that's not a problem at all. We choose the ethical route and that's that.)
The largely plant-based Mediterranean and DASH diets scored the highest in those health parameters and ease of staying on the diet, according to that US News & World Report listing.
