You forgot to hashtag #bacon to include this in the active #bacon trend.
That's one of those twitter things. I hate twitter. Since I like Google+ I'll learn. #bacon
Yep. I forget all the reasoning of why ketones are really efficient energy source. I'll have to read all of what he's got going on there.
That site is a serious time sink, but in a good way.
Something wonky in those numbers pre/post, pre "aerobic base" at 104 bpm, post at 162 bpm, whaaaat?

Power numbers will tell the real tale, as would training state/history.
aerobic base: He's not burning glycogen as a majority of his fuel until 162bpm.

I'm sure he's breathing pretty heavy at that point, regardless of fuel.
Shouldn't be breathing heavy, tis less than what he defines at the next level as "all day speed".

50/50 glyco/fat by his definition of "aerobic base".
His nomenclature of aerobic base seems odd. At 162 bpm, and to transition to more than 50% glycogen, seems high for aerobic base. It is an interesting topic using ketones for energy. I'm sure it takes a while to adapt your body to use ketones. I wouldn't think it would be a recommendation for all athletes to do, though, or even the general population.
Ketogenic diets are beneficial to folks with epilepsy and T2 diabetes.
Which is cool and all, but I personally haven't run across many Type II diabetics in bike racing, and without a wee bit of reproducible research, I have yet to be sold on ketogenic diets in general.
Ketosis won't keep one from bonking, to be sure.

Bonking isn't a problem: my activity level is pretty much sedentary compared to where I was 2 years ago. I currently bike to work 3 times a month and run about 8 miles a week.

But I also drink 1/3 of the coffee I used to. Keto feels like the fog has lifted.
