"[A]n increasing body of evidence is beginning to suggest that when eaten in isolation, fat doesn't contribute to weight gain. On the other hand, dozens of studies indicate that sugar alone is significantly tied to packing on pounds. That's not all. A recent analysis found that drinking sugar-sweetened beverages like soda was associated with an increased risk of death, particularly among people who drank at least two a day."

This 2017 review surveys 16 clinical trials testing the metabolic effects and health benefits of three intermittent fasting variations: alternate-day fasting, modified fasting regimens, and time-restricted feeding. The authors conclude intermittent fasting can improve metabolic markers related to chronic disease.

The speed and force with which the clean (and, yes, the snatch) drives loads give it developmental properties that other weight training movements cannot match. Deadlifts, squats, and bench presses will never approximate the speed and force and consequently the power required of a clean at larger loads. For this simple reason, while these are important movements, they are not the clean’s peers. Power is that important.

This 2013 analysis, led by Robert Lustig and cited in his lecture at CrossFit HQ on March 9, 2019, investigates the association between sugar availability and diabetes through a review of international food supply data from the U.N. Food and Agricultural Organization. While the analysis is limited by its correlative nature and other issues surrounding both international and observational research, the data indicate that changes in sugar consumption have a stronger association with diabetes prevalence than changes in overall caloric consumption and that, at a population level, sugar consumption and GDP predict diabetes prevalence.

"From 1997 through 2016, medical marketing expanded substantially, and spending increased from $17.7 to $29.9 billion, with direct-to-consumer advertising for prescription drugs and health services accounting for the most rapid growth, and pharmaceutical marketing to health professionals accounting for most promotional spending."

Prof. Tim Noakes shares a telling anecdote that demonstrates how Gatorade and the Gatorade Sports Science Institute (GSSI) sought to promote their commercial interests by mischaracterizing dehydration as a medical disease and propagating a fundamental misunderstanding of the causes of hyponatremia. In 2004, Noakes took a quiz on the GSSI website. The quiz was designed to test scientists’ and medical professionals’ knowledge of the factors that cause hyponatremia. Noakes, a foremost expert in the field, failed the quiz, which he determined was a lesson in indoctrination, not real science. Here, he recounts the experience while analyzing the flaws in each of the quiz’s seven questions.
