According to Adrienne Rose Johnson, the idea that the primitive diet was superior to current dietary habits dates back to the 1890s with such writers as Dr. Emmet Densmore and Dr. John Harvey Kellogg. Densmore proclaimed that "bread is the staff of death", while Kellogg supported a diet of starchy and grain-based foods.[11] The idea of a Paleolithic diet can be traced to a 1975 book by gastroenterologist Walter Voegtlin,[7]:41 which in 1985 was further developed by Stanley Boyd Eaton and Melvin Konner, and popularized by Loren Cordain in his 2002 book The Paleo Diet.[8] The terms caveman diet and stone-age diet are also used,[12] as is Paleo Diet, trademarked by Cordain.[13]

Saturated fat has been demonized by our health authorities and media. What is the basis for this position on Saturated fat? Are current recommendations for VERY low saturated fat intake justified? How much saturated fat (and what types), if any should one eat? Without a historical and scientific perspective these questions can be nearly impossible to answer.

To the outside world, though, as Glassman's company has exploded from a cult fitness website to a gym concept primed to have more locations than Curves by the end of 2013, CrossFit can appear risky, unhinged: Here is a fitness routine that has sent people to the hospital, overseen by people who may have had no more than two days of instruction. (Although every real trainer I met had considerable experience and was genuinely excellent, I attended the seminar and passed the test on my fourth day reporting this story. I am, believe me, no fitness savant.) And it's all led by a man who, in a 2006 comment, wrote, "We have a therapy for injuries at CrossFit called STFU." As in, Shut the f-k up. That's enough to make even the most devoted laissez faire-ists get a little, well, Uncle Pukie.

The paleo diet is promoted as a way of improving health.[2] There is some evidence that following this diet may lead to improvements in terms of body composition and metabolic effects compared with the typical Western diet[6] or compared with diets recommended by national nutritional guidelines.[9] There is no good evidence that the diet helps with weight loss, other than through the normal mechanisms of calorie restriction.[10] Following the paleo diet can lead to nutritional deficiencies such as an inadequate calcium intake, and side effects can include weakness, diarrhea, and headaches.[3][10]

You may notice that the following meal plans do not include any snacks. This is because, technically, snacking isn’t really something you should do while on a Whole30. Just be sure you’re getting enough food at each meal (which may be hard at first as you adjust to eating whole, real food and no processed “foods”) and you won’t need to snack. If you do feel the need to eat something between meals, try to keep some cut-up veggies on hand so you’ve got something easy and quick nearby and aren’t tempted to grab something non-Whole30.

CrossFit is promoted as both a physical exercise philosophy and a competitive fitness sport, incorporating elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, girevoy sport, calisthenics, strongman, and other exercises. It is practiced by members of over 13,000[6] affiliated gyms,[7] roughly half of which are located in the United States,[8] and by individuals who complete daily workouts (otherwise known as "WODs" or "workouts of the day").[9][10] CrossFit has been criticized for allegedly causing people to suffer from unnecessary injuries and exertional rhabdomyolysis.[11][12][13]
