It's a fair point about skiing being an anaerobic activity and that on a ketogenic diet, your top end performance suffers. The point that Peter Attia makes in his presentation, is that once you become Keto-adapted, you develop Metabolic Flexability. In otherwords, because you use less glycogen as a fuel source, when you eventually do need it, it is much quicker to replenish. Probably a Fight or Flight mechanism.
Is all skiing anaerobic? How much does conditioning have to play on your bodies ability to recover/ replenish glycogen? What if you never reach your Anearobic Threshold?
Yeah, interesting questions all. Particularly for recreational skiers. If you aren't concerned with the absolute maximum performance, can a ketogenic diet provide good-enough performance?
I just noticed this other post from Peter: http://eatingacademy.com/sports-and-nut ... n-co-exist which is fascinating. He claims to be able to calculate his glycogen deficit and maintain ketosis by simply replenishing exactly the amount of carbs he needs. This seems sort of similar to the cyclical ketogenic diet except that it is precisely targeted. It's an uber-physio-geek approach that isn't particularly practical for the average person, but it is fascinating none the less...
