First of all, it’s unclear if it can really live up to its claim to improve overall health by following the diet of our ancestors. While we can all benefit from reducing our intake of processed foods and increasing fruit and vegetable consumption, many dispute whether our ancestors were really all that much healthier than we are today given their significantly shorter life span. In fact, one study even demonstrated that they may have had increased rates of atherosclerosis, or hardened arteries. (5)
“Hartwig, a sports nutritionist and cocreator of the Whole30 diet plan, packs her fourth book on the subject with 150 recipes that are, as the cover proclaims in all-caps, “totally compliant.” That means heavy emphasis on eggs, meat, fish, and fresh vegetables, but no grains, dairy, legumes or added sugars. Whether or not one buys into Whole30, there is no denying that Hartwig has come up with a clever array of healthy and flavorful dishes. Highlights include Asian beef zoodle (zucchini noodles) soup, which is similar to Vietnamese pho but uses zucchini noodles, and grilled Jamaican jerk salmon with fresh mango salsa. Many of the recipes come courtesy of guest cooks from various food blogs. For instance, Michelle Smith, from the Whole Smiths blog, contributes cherry-chipotle BBQ chicken thighs, with the fruit providing the sweetness and ground chipotle bringing the heat. Veteran food and cocktail photographer Brent Herrig drives home the point that a burger served on a tomato slice is as delectable as one on a bun, and that meatballs do just fine in a cream sauce made with coconut milk.

CrossFit, Inc. licenses the CrossFit name to gyms for an annual fee and certifies trainers. Besides the standard two-day "Level 1 Trainer Course", specialty seminars include gymnastics, Olympic weightlifting, powerlifting, strongman, running and endurance, rowing, kettlebells, mobility and recovery, CrossFit Kids, CrossFit Football, and self-defense and striking. Other specialized adaptations include programs for pregnant women, seniors, and military special operations candidates. Affiliates develop their own programming, pricing, and instructional methods. Many athletes and trainers see themselves as part of a contrarian, insurgent movement that questions conventional fitness wisdom. In addition to performing prescribed workouts, they follow CrossFit's nutrition recommendations, adopting a paleo and/or zone diet.
The WHO trial (so named because the international team of principal investigators contained World Health Organization members) tested the potential of clofibrate, a “pre-statin” cholesterol-lowering agent, to reduce heart attack morbidity and mortality. The investigators ultimately concluded that clofibrate "cannot be recommended as a lipid-lowering drug for community-wide primary prevention of ischaemic heart disease.” Nevertheless, clofibrate remained in use until 2002, when it was pulled for increasing cancer rates. In their review of studies such as the WHO trial, Uffe Ravnskov and David Diamond observe, “Despite the largely disappointing findings from 50 years of cholesterol lower[ing] trials, the indictment and conviction of cholesterol as the causal agent in CVD [cardiovascular disease] has stood the test of time. … [Yet] the grand effort to reduce cholesterol as a strategy to improve health has failed.”
