CrossFit Health is an investigation into the ills of modern medicine and the wilful abuse of the public’s trust in science. The lessons learned from the legal dismantling of fake science, a crooked journal, and perjuring scientists have given us a forensic view as to how everything might have gone so wrong. We’re calling the combination of runaway medical costs and disease rates — which many profit from but none combat effectively — “The Mess.”

Dr. Aseem Malhotra, MD, explains which lifestyle factors can impair immunity and which are protective against respiratory illness. As more data on the coronavirus becomes available, it is becoming clearer which groups are at greater risk of developing severe complications. Obesity, Type 2 diabetes, high blood pressure, and smoking appear to put people at greater risk, while exercise and good nutrition improve the body’s defenses.

Dr. Aseem Malhotra is a best-selling author, researcher, and one of the most well-known cardiologists in the U.K. His views on cholesterol and sugar, controversial primarily among those who choose to promote special interests at the expense of public health, have landed him in numerous front-page news articles and on primetime television shows. Here, Malhotra discusses his experiences moving from clinical practice into the public eye and shares the lessons he has learned about public health advocacy along the way.

Evidence-based medicine (EBM) grew from the recognition that medical recommendations should become more scientific, Dr. Malcolm Kendrick explains. Unfortunately, several factors confound the endeavor. Kendrick notes life expectancies have begun to decline in the U.S. and U.K. and suggests this may be due, in part, to the unreliable evidence doctors use to treat their patients. Citing prominent voices from the scientific scholarship, he discusses several reasons why our most trusted studies — randomized controlled trials and meta-analyses — are unreliable. “Can EBM be salvaged?” Kendrick asks. “Only if the public and politicians, and of course doctors, wake up to the fact that ‘something has gone fundamentally wrong with one of our greatest human creations,’” he concludes.

Jim McCarter, MD and Ph.D., is an expert on the ketogenic diet, particularly its effectiveness for treating and reversing Type 2 diabetes (T2D). McCarter’s research into the health-related effects of corn syrup and sugar led to his discovery of many misconceptions he had “dating back to medical school.” During this presentation, McCarter focuses on correcting some of these misconceptions about nutrition and metabolic health. He outlines the benefits of ketosis and equips listeners to address 40 common myths about the ketogenic diet.

“American taxpayers spend $30 billion annually funding biomedical research. By some estimates, half of the results from these studies can’t be replicated elsewhere — the science is simply wrong. Often, research institutes and academia emphasize publishing results over getting the right answers, incentivizing poor experimental design, improper methods, and sloppy statistics. Bad science doesn’t just hold back medical progress, it can sign the equivalent of a death sentence. ... In Rigor Mortis, award-winning science journalist Richard F. Harris reveals these urgent issues with vivid anecdotes, personal stories, and interviews with the nation’s top biomedical researchers. We need to fix our dysfunctional biomedical system — now.”

Cristin Kearns was managing dental clinics for Kaiser and researching the link between gum disease and Type 2 diabetes when she came across a brochure with the CDC’s dietary recommendations for diabetics. The bad advice she found in the brochure forever altered the trajectory of her career and led to her development of a large digital archive — a record of instances in which the Sugar Association, a 501(c)6 formerly known as the Sugar Research Foundation (SRF), used public relations campaigns and industry funding to influence scientific research, education, and public policy in support of its mission to promote sugar consumption.

In September 2019, "The Chair of the British Parliament Science and Technology Committee, Sir Norman Lamb MP made calls for a full investigation into cholesterol lowering statin drugs. It was instigated after a letter was written to him signed by a number of eminent international doctors including the editor of the BMJ, the Past President of the Royal College of Physicians and the Director of the Centre of Evidence Based Medicine in Brazil wrote a letter calling for a full parliamentary inquiry into the controversial medication. Here, lead author Cardiologist Dr. Aseem Malhotra makes the case for [why] there’s an urgent need for such an investigation."

“There seems to be a prevalent idea that cholesterol is a wholly undesirable substance. It should be pointed out that it is an essential constituent of all animal tissues and undoubtedly plays an important role in the normal function of all cells. To eliminate cholesterol from the diet means the elimination of animal foods from the diet — meats, milk, eggs, etc. These are the protective foods which nutritionists have clearly shown are essential for an adequate diet. … The proposition that low cholesterol diets be used as a preventive for the development of atherosclerosis would mean that animal foods be omitted from our diets. This is equivalent to the negation of practically all that nutrition science has taught us in the past. Such a course may well be disastrous.”

Maryanne Demasi, an investigative journalist with a Ph.D. in rheumatology, shares highlights from her interview with Danish physician Uffe Ravnskov. Ravnskov, a famed cholesterol skeptic, has gained worldwide significance for his persistent fight against the demonization of cholesterol. Though he once believed additional research would “out the absurdity of a narrative that cast saturated fats and cholesterol as dietary villains,” he has since become an active crusader against misinformation and the corruption of science, publishing more than a hundred articles in well-known scientific journals in an effort to set the record straight on cholesterol.

In this talk at CrossFit’s 2017 Health Conference, Australian orthopedic surgeon Dr. Gary Fettke presents a history of the junk science behind prevailing nutrition guidelines. Fettke has come under attack for his critique of the mainstream: Because of his dietary recommendations (“low-carb, healthy fat”), Fettke was reported to Australia’s medical board. But “the message is too important to be silenced,” Fettke states. “I feel that the combination of fructose, refined carbohydrate, and polyunsaturated oils is toxic, inflammatory, and at the root cause of all disease that we look at.”

Dr. Zoë Harcombe has become an expert in the corruption and error plaguing the health sciences — a dire situation that she, like CrossFit Founder Greg Glassman, refers to as “The Mess.” Harcombe defines “The Mess” as “the escalating disease (and) the escalating medical costs, which many people are profiting from but none are combatting effectively.” During a presentation delivered on July 31 at the 2019 CrossFit Health Conference, Harcombe outlined many factors that contribute to this growing problem — specifically, the role of dietitians and the food and beverage industry in influencing how and what we eat, accreditation that regulates who can offer dietary advice, and the disparity between what we are told to eat and what the evidence suggests we should eat.

Commercial interests have discovered numerous ways to co-opt the loyalty of health professionals to promote company-sponsored studies and marketing messages. Here, Dr. Maryanne Demasi describes just a few of the indications that Australia’s National Heart Foundation (NHF) has sold its soul to industry. She focuses specifically on the NHF’s ties to junk food and pharmaceutical companies, citing responses from various scholars who have expressed deep concern over how the NHF’s receipt of industry funding might threaten public health.

Dr. Jason Fung, MD, is a nephrologist and expert in the use of intermittent fasting and low-carbohydrate diets for the treatment of Type 2 diabetes. In this presentation, delivered on Aug. 2, 2018, at the 2018 CrossFit Health Conference in Madison, Wisconsin, Fung shares his first-hand experiences with “The Mess” in the medical sciences and discusses how he shifted his research and clinical practices as a result of those experiences. He explains why long-term weight loss is so difficult, introduces the concept of therapeutic fasting, and dispels common myths associated with the fasting process.

“Most people let their doctor make the decisions for them, but the evidence tells us that we should be cautious,” Professor Peter C. Gøtzsche explains. Gøtzsche, a specialist in internal medicine, also recommends avoiding medications whenever possible. “We live in a world that is so overdiagnosed and overtreated that in high-income countries, our medications are the third leading cause of death after heart disease and cancer,” he observes.

“Framingham investigators seemed to be objective in their early reports but subsequently exhibited stronger and stronger biases. The use of such terms as ‘powerful’ to describe an exceedingly weak relationship has been commonplace. One kind of bias exhibited was the process of reinterpreting data in order to be consistent with the current position of the alliance (the group providing the funding; i.e., the NHLBI).” —Russell Smith

“The Framingham Heart Study laid the groundwork for the obsession we’ve had with cholesterol and saturated fat and may well be the study that has been most damaging to the health of the U.S. population. This damage comes not necessarily from the study’s data but from the misreporting, deception, dissembling and outright prevarication about the data that have made it the wellspring for both the diabetes and obesity epidemics that afflict us.” —Dr. Michael Eades
