    What's good about it specifically? Doesn't seem to be anything groundbreaking. Volek is a known low carb advocate, so it's really not surprising..

    It's so interesting that the body can convert to using fat for fuel instead of glucose. The article is not written by Volek, but it quotes him since he's an expert on the topic. It also quotes Louise Burke, who says no study to date shows that a high fat diet leads to better athletic performance. It's a pretty unbiased article on the topic. I'm sure we'll be seeing more studies on athletes in ketosis in the near future.

    Well right, that's my point. The summary is "maybe it can be beneficial but we haven't been able to prove anything yet"....regardless of it is unbiased or not.

    Yeah, but it's just so cool that the body can make the conversion from glucose to fat for energy, right? Also, if an athlete has a seizure disorder, it is definitely worth looking into.

    They've already happened. For anything involving high intensity, going VLC has a disastrous impact on performance. Every example of a successful "low carb" athlete has turned out to be in reality a "lots of carbs but not quite as many as I used to eat" athlete. The infamous Lakers "low carb" diet, for example, was about 30% carbs, which on a 4000+ intake means 300g/day of carbs.

    That is a loooooooooooooong way from a 30g ketosizer.

    Only to an extent.

    Not sure what happened there. Consider it a riff on your theme. :)

    I'm eating at 1200 cal and quite a bit of exercise, so it's been a juggling experience for me. Once I adjusted to my input in terms of satiety, higher carb totally wins for functional energy the next day.

    In another week, my calories will start creeping up, so don't bother lecturing me. :)

    So the athletes having only 30% carbs before a big event, assuming they are "fat loading", do they fare better or worse than the athletes carb loading? I've heard of mountaineers eating entire sticks of butter on expeditions.

    Not "30% carbs before a big event" - every day, otherwise they wouldn't be able to train properly.

    And eating sticks of butter does not in any way imply ketosis.

    It implies using ketones for fuel.

    You cannot oxidize enough fat to be a competitive runner/cyclist. If you want to be a mid-pack runner (at marathon distance) you can oxidize enough fat. Longer duration events (where you run slower, ie ultras) are more interesting for this approach.

    Thanks for the input everyone, good stuff!

    No, it does not.

    Somehow, I don't think the upcoming Low Carb Winter Olympics will be quiet the crowd pleaser the regular Winter Olympics are, but at least the athletes get as much Bullet Proof Coffee as they can stomach to keep warm.

    Ketones are an acidic by product of fat metabolism.

    I think they only do that because butter has the best calorie to weight ratio. I guess that means that efficient ketosis would be very helpful for mountaineers.

    Thanks! That helps understand it.

    Hasn't this discussion now moved well away from ketone-fueled sports performance, though? I thought that was the point trying to be proven, and all I'm seeing proof of is that butter is a space-efficient source of dense calories.

    Producing ketones does not mean ketosis. Eating high fat is not enough to induce ketosis.

    That it really doesn't sound like you know what ketosis is.

    The body is a great thing. It can run effectively with or without a lot of carbs.

    WTF!! I've never had anyone put words in my mouth like that!! Where did I say "all you need for ketosis is eating high fat"? You have no farking idea what I know.
