Advocates of the diet argue that the increase in diseases of affluence after the dawn of agriculture was caused by changes in diet, but others have countered that it may be that pre-agricultural hunter-gatherers did not suffer from the diseases of affluence because they did not live long enough to develop them.[29] Based on the data from hunter-gatherer populations still in existence, it is estimated that at age 15, life expectancy was an additional 39 years, for a total expected age of 54 years.[30] At age 45, it is estimated that average life expectancy was an additional 19 years, for a total expected age of 64 years.[31][32] That is to say, in such societies, most deaths occurred in childhood or young adulthood; thus, the population of elderly – and the prevalence of diseases of affluence – was much reduced. Excessive food energy intake relative to energy expended, rather than the consumption of specific foods, is more likely to underlie the diseases of affluence. "The health concerns of the industrial world, where calorie-packed foods are readily available, stem not from deviations from a specific diet but from an imbalance between the energy humans consume and the energy humans spend."[33]
Alcohol is a no-no if you are strict paleo. Beer is made from grains, and liquor also contains traces of gluten. But, good news for cider-lovers: most hard ciders are gluten-free, so they are allowed. Check the label to be sure. Red wine is more accepted in the paleo community because it contains the antioxidant resveratrol, but sorry chardonnay lovers, white wine is technically not allowed.

An early client of Glassman's described the CrossFit experience as "agony coupled with laughter." Glassman liked that. It was as if his increasingly fit posse had a subversive secret: combinations of exercises that seemed strange and reckless and maybe dangerous to the ignorant. When Elizer, who volunteered to build the website, asked Glassman if he had a logo in mind, Glassman thought about the idea of agony mixed with laughter, then thought about thumbing his nose at all the ho-hum personal trainers he had ever endured. He came up with a vomiting clown. He called it Uncle Pukie.
Workout 4A & 4B has an 11 min time cap. It is a chipper that begins with the athlete standing tall behind their measured handstand-pushup box. At the start of the ascending clock, the athlete will kick up to a locked out handstand before performing their repetitions. They will then move onto the pull-ups and complete 50 repetitions before moving to the toes to bar to complete another 50 repetitions, and lastly onto the wall-balls, complete 50 repetitions. Athletes may take as many sets, breaking up the work as needed, to complete the required number of repetitions throughout the workout.
It should be noted that U.S. News & World Report just released its annual ranking of diets, and Whole30 ranked dead last. Why? Essentially, the expert panel of over 20 registered dietitians, academics, and medical doctors found the program unsustainable and potentially unhealthy, since, among other issues, it restricts certain food groups and is high in sodium and cholesterol. But, Whole30's co-creator Melissa Hartwig stands behind the program, telling that its animal protein recommendations are in line with government recommendations, and that there are no nutrients in temporarily restricted foods, like grains and legumes, that you can't find in fruits and vegetables.
Greg Glassman and Lauren Jenai founded CrossFit, Inc. in 2000.[14][15] The company was conceived a few years earlier, in 1996, as Cross-Fit.[16] The original CrossFit gym is in Santa Cruz, California, and the first affiliated gym was CrossFit North in Seattle, Washington; there were 13 by 2005, and today there are more than 13,000.[6] Coaches associated with CrossFit include Louie Simmons, John Welbourn, Bob Harper, and Mike Burgener.[17]
