There are people who recommend obese people adopt diets that induce ketosis. These people are not suggesting diets that should be followed by everybody. However there are also people who say that carb intake should be greatly reduced across the board for everybody, that even something seemingly extreme like a 90% reduction of carbs in the average diet wouldn't be enough to induce ketosis but would nevertheless be far healthier. However the current size of the human population is incompatible with anything other than the vast majority of people getting the vast majority of their calories from carbs. For that reason, people recommending a large reduction on carb intake across the board will almost certainly continue to be marginalized, pushed to the sidelines in most mainstream discussions.
