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.

"Lifting and carrying bags of groceries, pulling down your suitcase from a train’s overhead luggage rack, bending down to pick something off the floor, or climbing stairs are all examples of 'functional movement' we all do daily. CrossFit™ aims to provide opportunities for people to prepare themselves to tackle these functional movement needs. ... CrossFit™ is training everyone, young and old, to stay healthy, well, and engaged with the world around them. The program is 'infinitely scalable,' meaning prescribed workout patterns (weights, movements, etc.) can be changed to accommodate the needs of anyone, regardless of age, who wishes to participate."

This 2017 review surveys 17 trials that tested the effects of a very low calorie diet (VLCD) on people with diabetes. A VLCD is defined as a diet of fewer than 800 calories per day. Seven of 14 trials that looked at fasting glucose showed that a VLCD led to significant improvements, while three out of four found the same for fasting insulin. Nine studies looked at blood pressure, and all showed significant improvements. Ten of 14 studies that tracked blood lipids showed significant reductions in total cholesterol and triglyceride levels. No adverse effects linked to VLCDs were reported. This review shows the difficulty of using existing evidence to clearly assess the impact of a VLCD on diabetes, in large part because the parameters of a VLCD have not been consistently defined. However, the review also shows that a number of trials using VLCDs demonstrated rapid, clinically meaningful improvements in metabolic markers that were sustained even after the VLCD concluded.
