William:

After some digging around on this, I can say with certainty: I don't really know. If you're predominantly fast twitch (question: how do you know?), then it would be interesting and somewhat counter-intuitive that your body prefers near zero carb, when fast twitch operate off glycogen, from what I've gathered.

On the other topic, I too seem to do best on little to no vegetable, fruit, nuts or dairy. Frankly, I don't know if that presents a health issue down the line. I tend to doubt it. I think our bodies are individually and massively complex and how we feel should never be discounted. In fact, I think it ought to be the highest authority, provided what we're eating is real food.

The diet probably helps, and maybe there is something to it. But, I am finding that a paleo/zone/primal approach is probably a better all around approach for many of the reasons you describe…mostly related to hormonal (insulin) control. In the end, for athletics, you have to find what works best for you…but I think that a break from the traditional 65% Carbohydrate diet even for extreme endurance athletes is better. Limiting carbs to more like 40% (very high for primal/paleo) if you are pretty extreme (hours on hours of high end aerobic) exercise. Definitely primal/paleo for the Crossfit/EF/HIIT training with smartly placed carbs.

Robb Wolf has some very good stuff about this. I'm more of an experiment of 1, but am becoming more convinced that fewer carbs, more protein, more fat (this is key) is the best way to fire on all cylinders more of the time.

I wish him well.

This is going off topic of what you were asking for so I will quit before I start ranting.

Richard – you have a great blog and I actually like the fact that you can be a bit direct (and cranky) at times. All good! No good in pretending to be something that you are not. For me, that is what shines through in your blog – we are getting your thoughts, opinions and rants – warts and all.
Keep it up.

I would like to see a photo of your progress soon though

Of course, anyone targeted by such criticism is welcome to come defend themselves.

I'm trying to get through the comments (many, still) I can without a lot of reflection or research. So, let me see what i can come up with tomorrow. Some of your observations are interesting.

I CAN NOT BELIEVE HOW EFFING DUMB THEY HAVE BEEN FOR YEARS AND CONTINUE TO BE ON THIS POINT.

I GET THIS REQUEST ALL THE TIME. I HAVE ASKED TYPEPAD PEOPLE ABOUT IT AND THE RESPONSE IS AS THOUGH THEY'VE NEVER HEARD IT BEFORE. IN MANY WAYS, THEY TOTALLY SUCK.

But, I get that it needs to be intermittent. I think I'm accomplishing that, i.e., not all the time. Do you disagree?
