Re: Lower Fat vs Lower Carb study

Can you give us an example of an elite cf athlete who does adhere to that type of a diet while training/competing?

Russel Berger, Jason Kahlipa....

Maybe more importantly... a great many firebreathing ordinary crossfit folks. At my cert at least 80% of the people there were chowing down meat, nuts, seeds, some fruit, little starch and no sugar.

Oat bran, mashed potatoes and sandwiches are totally low carb...

Yeah I'll take results over rhetoric every single time. A carb-heavy diet makes sense for elite marathoners who run 125+ miles a week. Elite Kenyan distance runners eat 600g of carbs per day and get a ton of their calories from sugar. So is that what we should do? It sure doesn't seem necessary for people who mostly do resistance training and small amount of cardio/interval training.

I just completed the cert with both of them. Sorry, I don't have a link.

We can dance around all day, but the fact remains that there are thousands of crossfitters out there doing low carb high protein/fat, performing optimally. Regardless of the text book nutritional analysis, it seems to be working. This is the reason the CF advocates it as far as I can tell. I just wonder how this can be explained. If there was a clear advantage to eating low fat high carb (or some other way) this would be obvious because of the way we are able to measure our progress and output.

There is no need to explain something that has not been demonstrated. It is not enough for you to simply claim it. First of all, the ONLY description of anyone's diet is an accurate food log. Not what they report and not what they label it. Do you know for a fact what these thousands of crossfitters actually eat? And do you understand how difficult it is for any individual to know that they are performing "optimally?" We're talking about very time-consuming personal experimentation, and even then it will be lacking controls.

And all it takes for CF to officially advocate something is for Greg Glassman to say it should be advocated. Period. Not because there is any evidence, empirical or otherwise, that it actually works.

You keep increasing the numbers of these hypothetical athletes, but so far haven't actually demonstrated that any of them exist.

You also haven't demonstrated that they are performing "optimally," and you haven't looked at the thousands of crossfitters who are *also* performing "optimally" even though they *aren't* eating a low carb, high protein/fat diet. Nor have you addressed the abundant evidence, on this board and elsewhere, from athletes who find that low carb diets are disastrous for them.

I am going out on a limb.... to suggest that there are a substantial number of crossfitters that follow the diet that is prescribed by Crossfit?

I don't think I am.

Are those people achieving elite level fitness through Crossfit and the prescribed diet? Again, I don't think that is an unreasonable assumption that at least a few are. If the claim here is that a low carb diet is not optimal, why are optimal results being achieved?

Well first, I'm still waiting for evidence that they are.

And second, "optimal" implies that the low carb diet achieves *better* results than other diets, which is an even higher bar. Indeed, if half of the top twenty Crossfitters are following a low carb diet (which I doubt) and half are not, then the low carb diet would only have demonstrated that it's no worse than the alternatives, not that it's "optimal."
