This is a valid point. One of the reasons why keto can fail to get you a six-pack is surplus or even equilibrium of calories. You still need a caloric deficit. Keto-adaptation (4-6 weeks is necessary) prepares your enzymes to burn fat instead of glucose and takes away sugar fluctuations and hunger, making caloric restriction possible.
A clear sign of keto-adaptation for me (and I see it repeated by keto experts), is that you are almost never hungry and can go without eating much longer without even thinking about food.
