Came across an interesting vlog by a popular proponent of fasting/cyclical keto diets, etc. He claims he has abandoned CKD after experimenting with a protein-driven ‘carb up’.
Wondered what others think of the theory behind this: in essence, the idea is you consume a high amount of lean protein, e.g. 400-600g, and nothing else. The process of gluconeogenesis will then convert a chunk of this to glucose to be stored. The effect is you get a carb load without drastic energy swing, rising insulin, etc.
I have researched Lyle McDonald on this but he doesn’t appear to quite address this in depth.
