What are your carb sources? I would cut down carbs. See if your workouts suffer from it. I am cutting my carbs right now and so far, so good. The first few days were a little dodgy, but my energy has leveled out. I do NOT however do Crossfit, but do workout rather regularly on my own and do conditioning drills, as well as a lot of strength work. I'm not sure if or how it compares to CF.

CrossFit On a Low Carb Paleo Diet: Mat Lalonde Reporting
I have no idea what a "Fran" is, maybe somebody can shed light on that. I'm just assuming it's a hard workout where people usually drag their asses. It seems Mat Lalonde had a good experience with this. [[Also, I vaguely recall a post by either Robb or Mat where they talk about how they crashed HARD after one workout on VLC... but I can't find it, if somebody knows of this -- and it's dated after this article -- would you mind posting it? thanks]]
It's been roughly a week since I started, so not enough time. All I'm doing differently is not eating potatoes. I usually always eat meat and/or eggs, then some quick veggies, mostly the dark green variety, and that's it. I'm comfortable eating similar stuff day in and day out but the wonderful thing about protein is it has many faces. Fish of all delicious kinds, beef, pork, chicken, duck... shoot you'd be hard pressed to get bored I think.
I'm going to see how I do. I'm also replacing cream with coconut milk but do still use butter, not everyday, but sometimes.
