Sure. But if you live even a little bit active lifestyle, you are going to have issues with this, as converting fat to energy is a much harder process. You can try to counter the point by pointing out that there are ultra-marathoners who are keto. But my two counters against this are: 1) They generally still use some form of carbs during the race, i.e. sugar packets. 2) There is no world class sprinter / 5k / 10k / sprint biker / football player / soccer play that is keto. So fine, you can make the argument that no carb is a better diet for an office potato with no exercise. But I would argue that bumping your carb intake up 25-40% and doing some exercise is going to lead to a much more healthy body and mind (many studies around on the benefits of exercise). TLDR: The problem with office potatoes is being an office potato. You are better fixing it via exercise, vs trying to eat a weird diet that lets you stay skinny while an office potato.
