What Lyle said. This gets advocated over and over. I saw this being asked 10 years ago and I've read logs of people doing it.
The results suck and the gains are minimal. Keto is not a diet for bulking including CKD and TKD. Your body needs to be in an anabolic state overall for continual growth. As Lyle mentions, anything involving ketosis is catabolic and doing the opposite..
