I think the deal with primal is that it is a lifestyle and the eating supports an activity level that lacks the day to day intensity of CrossFit. He pretty much doesn't support CrossFit.
Since I started CrossFit, I'd say I am closer to paleo than primal. I still eat the clean foods, but eat less fat and more carbs. I think above all, you can't have it both ways. You can't eat a ribeye, potatoe, butter, sour cream, banana and chocolate. You can eat a ribeye, butter and chocolate OR you can eat sirloin, potato and a banana. For me, the leaner meats, less fat and higher carbs make my workouts better. And I focus on protein above all.
I try and eat per the WOD. On a lifting day, lots of protein, more fats, less carbs. Yesterday was Filthy Fifty so I ate a lot of carbs and starches, protein and much less fat. My dinner was a protein shake with a lot of fruit as I literally could not fathom eating something high in fat.
I'm now down two dress sizes and up 5 lbs since starting Crossfit about 3-4 months ago, so I'd say I am putting on lean mass and burning fat. The trade off is that I do believe I carry around more water weight, which is OK with me.
And pretty much Mark Sisson doesn't advocate CrossFit. His "primal" weight loss fitness suggestion is a lot different intensity than CrossFit. I think you need to follow the primal system for it to work. So it is probably not the best nutrition to follow for constant high intensity working out. Just like eating more carbs isn't going to really cut it for the lower intensity PB workout.nobody is saying that fruit isn't primal, but eating mountains of it isn't recommended as a fat-loss technique in the pb either
Another thing, while I am making points. A really hard intense holy shit sprint workout kills my appetite. And if I go into a workout like that feeling for lack of a better word, satiated, it just shuts me down. I like being a little hungry. A lot of primal is based around eating in a way that you don't feel hungry.
i find any intense workout to shut down my appetite for awhile too, even if i go in in a fasted state.
i disagree though about "eating so you don't feel hungry." if you're not eating lots of junk/grains/sugars you're not falsely tripping the switch that screams "EAT RIGHT NOW ZOMG IMMEDIATELY IF NOT SOONER!!!!!!!!!!!" and many on here seem to find no hassle in going 12+ hours without eating. i find even if actual hunger rears its head, it's pretty easily tamped down. like you, i like feeling hungry sometimes. keeps me better in-tune with what and when i eat.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.

Eating fruit is not the same as drinking a coke. The reason high fructose corn syrup is such as problem is that if you took a 32 ounce coke and tried to cut enough sugar can to equal the sugar content, you'd need a sugar cane 8 feet long. It's physically impossible to eat that much sugar. However, you process sugar from corn, concentrate it and then dilute it with a small bit of soda water and bam...you magically have concentrated sugar.
Imagine now this sugar content in all your foods.
Fruit has a very smart amount of sugar in it and it releases very slowly in the gut. There is no worry about fruit. In addition, fruit has a lot of important anti-oxidants and nutrients. I'd say eat away...at least until we kill off the honey bee anyway.
Make fruit time an excuse to try new fruits, as well.
