If you want to dunk, you don't need crossfit, you need knowledge of plyometrics and you need a bigger squat. I can see it helping somewhat in the knowledge department, but so can a weekend reading starting strength and the vertical jump bible.
P.s. - I'm training to dunk too.
Problem B:Humans seem to have adapted rather well to milk and grains
Problem C: Providing a diet high in red meat is environmentally unsound / impossible
Problem D: Health problems resulting from a diet high in red meats
Main Outcome Measures Primary outcome was resting energy expenditure (REE), with secondary outcomes of total energy expenditure (TEE), hormone levels, and metabolic syndrome components.
Conclusion Among overweight and obese young adults compared with pre–weight-loss energy expenditure, isocaloric feeding following 10% to 15% weight loss resulted in decreases in REE and TEE that were greatest with the low-fat diet, intermediate with the low–glycemic index diet, and least with the very low-carbohydrate diet.
A recent large study in the Journal of the American Medical Association found that people with diagnosed, undiagnosed, and “latent” celiac disease or gluten sensitivity had a higher risk of death, mostly from heart disease and cancer. (i)
This study looked at almost 30,000 patients from 1969 to 2008 and examined deaths in three groups: Those with full-blown celiac disease, those with inflammation of their intestine but not full-blown celiac disease, and those with latent celiac disease or gluten sensitivity (elevated gluten antibodies but negative intestinal biopsy).
The findings were dramatic. There was a 39 percent increased risk of death in those with celiac disease, 72 percent increased risk in those with gut inflammation related to gluten, and 35 percent increased risk in those with gluten sensitivity but no celiac disease.
And it’s not just a few who suffer, but millions. Far more people have gluten sensitivity than you think–especially those who are chronically ill. The most serious form of allergy to gluten, celiac disease, affects one in 100 people, or three million Americans, most of who don’t know they have it. But milder forms of gluten sensitivity are even more common and may affect up to one-third of the American population.
Agree there are a lot of problems with "paleo", the biggest one of which is that's a lot of people's interpretation of it is essentially dogma based on conjecture about what people may / may not have eaten. Also, there seems to be an obsessive focus on eating steaks. Muscle meat is the least nutritious part of an animal. Organ meat is where most of the goodness is.
When I first started researching paleo, I thought it was awesome. We changed our diet to fit todays "paleo" diet. It worked wonders for us, in total dropped about 75# between me and my wife in 6 months. A few months ago I meet a cattle farmer that does paleo. Talking to him, his "paleo" diet is far different than what todays fad paleo diet is, the basis of his diet is omega-3 intake. After doing research I have started working on improving our omega-3 intake, it has been eye opening how little omega-3 is in todays paleo diet!!!
