A strict paleo diet does not allow dairy products because hunter-gatherers did not milk cows. Some paleo dieters say dairy is OK, especially if it is grass-fed because grass-fed butter, for example, has more omega-3s. Fermented dairy products are also OK for some paleo eaters because they have a lower content of lactose and casein, the two concerns paleo dieters have with dairy.
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 Cosmopolitan.com 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.
At CrossFit, some coaches refer to this as “Uncle Rahbdo,” though it’s not something funny or enjoyable. You can read all about the condition and issues it can cause here. This typically occurs with (primarily male) ex-athletes who have not exercised for a while and come back trying to prove something, and end up working at a higher intensity than their body can handle.
Both feeling hungry all the time and never feeling hungry are common on the Whole30 diet, especially during the first two weeks as your body adjusts to new sources of energy. Eventually, though, you shouldn’t feel those pangs since protein and fiber are filling, and you’ll get plenty of both. Plus, you’re allowed to eat as much as you want and add Whole30-compliant snacks to your meal plan, provided you truly are hungry. One small study of 29 participants published in Nutrition and Metabolism in 2010 found Paleo eaters (who have relatively similar diets to Whole30 followers) felt just as full but consumed fewer calories than their Mediterranean counterparts.
Another 2014 study in the European Journal of Clinical Nutrition compared the effects of the Paleo plan to those of a standard low-fat diet on 70 obese, postmenopausal women. After six months, the Paleo group lost 14 pounds on average, while the other group lost nearly 6 pounds. After a year, the Paleo group had lost 19 pounds on average, and the low-fat dieters had dropped 10 pounds. A year later, both groups had regained some weight: The Paleo group was still down 10 pounds, while the low-fat group had dropped an average of more than 6 pounds.
CrossFit headquarters' aggression can be enough to stunt interest in the WOD--almost. In April 2012, two avid CrossFitters, Jason and Shannon Janke, opened up the PR Cave, a sporting goods store in Yorba Linda, California, designed to cater to boxgoers all around Orange County. In November, they added a sign, "Where CrossFitters Shop," and had the slogan printed on mixer bottles for protein shakes. On January 16, they received a cease-and-desist from CrossFit, objecting to the use of CrossFitter. A month later, CrossFit filed suit.

Every argument that your vegetarian friends use to avoid meat for health reasons is debunked here.
“I think there are a lot of positives about it,” Holley says. “It cuts out a lot of processed foods just naturally, like processed grains or added sugar through soft drinks or juice.” And because the diet promotes eating anti-inflammatory foods — like fruits, vegetables, and unsaturated fats in nuts and certain oils — your health could benefit, Holley explains. Cutting out processed foods and sugar will also help lower your risk of certain diseases, like type 2 diabetes and certain cancers, she says. (6)
