WRT KBW and ketosis…I’m a physicist so have always done KBW. If I am Keto-ing, I’m fine during high stress or big projects. When I’m not Keto-ing, like during the qualifier I wasn’t, I can gain MASSIVE amounts of weight because I feel the need to eat to concentrate. Of course, you have to get through the adaptation phase, but after that, yes, being in ketosis (or low carb anyway) can keep you doing heavy KBW without overeating. In fact, that is the only way I seem to be able to do it (do good work without eating constantly at my desk). This is all anecdotal of course.

You mentioned video games such as WoW increasing caloric intake, however I have put many hours on that game and always seem to not be hungry or eat while I am playing. I have friends that also play that say the same thing happens to them, not eating for hours at a time while engrossed in gaming.

I was merely making a rather pedantic correction regarding his disagreement with what I wrote in the article. And the brain still uses some glucose (~25% of it’s full requirements still come from glucose even after full blown keto-adaptation). And as anyone who’s done a ketogenic diet, blood sugar can still get crashed. Does that happen during KBW? I have no idea. Most of the studies that suggest that ‘ketogenic diets impair brain function’ look at them during the first week or so, long before adaptation has had time to take place.

Lyle – interesting post. thank you. i’m not sure i get your meaning when Scott questioned your statement that the brain can only use glucose, not fat. in a ketotic state the brain uses more ketones and less glucose than on our usual diet. but of course you know that; was your reply kind of shorthand?
i hope i don’t stay awake worrying about it……………

Chris: Sleep is very complicated and I cannot claim to be an expert in sleep dynamics. Certainly the first thing to deal with is sleep hygiene (your habits at sleep time) and there is a ton of stuff on the web about this. But avoiding computer/light in the eye, stimulants, having a set sleep time a whole bunch of stuff goes into helping people sleep better.

When that doesn’t work, there are numerous supplements that can help with sleep ranging from melatonin to 5-htp to taurine to all kinds of stuff in-between. The problem is that nothing works for everyone and there is often trial and error involved. This is because sleep can get messed up by a variety of different mechanisms and the different products all hit different pathways.

When that fails, drugs are an option, something I truly know nothing about.

I should stop doing things like reading and playing videogames. Drinking beer doesnt require much thought, I guess that is my next main mission.

very interesting review, Im way too obsessive to make my reading and playing make me fat. Drugs help as well.

Lyle – do you have any good resources to help with the sleep portion of the equation?

You ever had a raid go wrong?

More seriously, it’s a good point and I’m quite sure that it is the relationship of stress with the types of KBW being discussed here that is at issue.
