Organisation Description

CrossFit is a lifestyle characterized by safe, effective exercise and sound nutrition. CrossFit can be used to accomplish any goal, from improved health to weight loss to better performance. The program works for everyone—people who are just starting out and people who have trained for years.

CPD Courses and Workshops Available

  • Paleopathology and the Origins of the Paleo Diet by Dr. Michael Eades

    The composition of the diet of early Homo sapiens and their predecessors is relevant to current human health because; over the millennia; this diet shaped our genome. There are a number of ways by which information about their diet can be gleaned from the anthropological and archaeological literature. Over time; dietary changes can alter morphology. By correlating modern human morphology with that of human predecessors; we can make assumptions about changes in dietary composition. Stable isotope analysis is another highly technical way to determine the dietary intake of both modern and ancient humans.

  • Intermittent Fasting by Dr. Jason Fung

    U.S. dietary guidelines released in 1977 and the food pyramid of the 1980s cautioned Americans to restrict dietary fat and encouraged the regular consumption of grain by positioning it as the foundation of the diet. These recommendations corresponded with the rise of the obesity and Type 2 diabetes epidemics. Understanding the hormonal mediators (e.g.; ghrelin and insulin) of hunger and food storage is vital to understanding the physiology of feeding; fasting; and changes in body fat mass. Caloric restriction increases hunger hormones and decreases metabolism. Fasting decreases hunger hormones; increases metabolism; and decreases insulin levels. Refined carbohydrate consumption and frequent eating increase insulin levels. Therapeutic fasting is highly effective for regulating and improving metabolic health; but it is not profitable for the medical industry. Prescription drugs and surgical interventions are very profitable although minimally effective.

  • Cancer as a Mitochondrial Metabolic Disease by Prof. Thomas Seyfried; Ph.D.

    Most; if not all; cancers express abnormalities in the number; structure; and function of mitochondria. As structure is linked to function; these mitochondrial abnormalities would compromise energy metabolism through oxidative phosphorylation. Glucose and glutamine are recognized as the major fermentable fuels that drive cancer growth through glycolysis and glutaminolysis; respectively. In this presentation; Prof. Thomas Seyfried describes how he and his colleagues used the glutamine antagonist 6-diazo-5-oxo-L-norleucine (DON); administered together with ketogenic metabolic therapy (calorically restricted ketogenic diet; KD-R); to treat late-stage orthotropic growth in two syngeneic mouse models of glioblastoma (GBM): the highly invasive mesenchymal tumour VM-M3 and the high-grade stem cell glioma CT-2A. DON targets glutaminolysis while the KD-R reduces glucose and at the same time elevates neuroprotective and non-fermentable ketone bodies.

  • Carb Restriction as a Sustainable Diabetes Treatment by Dr. Sarah Hallberg; DO

    Carbohydrate restriction has been used to treat diabetes for over 100 years. Medication became the focus of treatment in the 20th century; but the side effects and costs have made that sole solution untenable. As a result; a renewed focus on carbohydrate restriction has emerged. In this presentation; Dr. Sarah Hallberg walks through the physiology behind the effective use of this diabetes treatment. She also discusses the outcomes of a program with 500+ participants that she and her colleagues conducted for Indiana University Health. Not only did those who followed the low-carb recommendation lose weight; many were cured of Type 2 diabetes as well. Hallberg notes that after one year; “60% of the patients with Type 2 diabetes had reversed their diabetes;” and 83% of participants were able to adhere to the diet.

  • The World’s Only Legitimate Exercise Science by Prof. Nathan Jenkins; Ph.D.; CF-L1

    Online Course | CrossFit Inc

    CrossFit Inc

    This talk presents an academic exercise physiologist’s perspective on the differences between mainstream exercise science and CrossFit’s exercise prescription; both for the health of the general population and for those with chronic cardiometabolic diseases. Prof. Nathan Jenkins sets up a series of comparisons during the talk. These include (i) the Physical Activity Guidelines for Americans (PAG) vs. CrossFit’s “Fitness in 100 Words;” (ii) the relative importance of the oxidative energy supply system as a mechanistic underpinning of health benefits of exercise according to the mainstream vs. CrossFit; and (iii) CrossFit’s reliance on rigorous modern science vs. mainstream academia’s reliance on postmodern consensus science as the fundamental explanation for differences in solutions to the problem of chronic disease.

  • The Mess: Money vs. Evidence by Dr. Zoë Harcombe; Ph.D.

    Online Course | CrossFit Inc

    CrossFit Inc

    Dr. Zoë Harcombe; Ph.D.; is an independent author; researcher; and speaker in the fields of diet; health; and nutrition. Here; she addresses “the escalating disease (and) the escalating medical costs; which many people are profiting from but none are combatting effectively.” She outlines 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.

  • The Quality of Calories: Competing Paradigms of Obesity Pathogenesis; a Historical Perspective by Gary Taubes

    Online Course | CrossFit Inc

    CrossFit Inc

    Long-held beliefs about the role of energy balance in weight regulation and obesity may be flawed and lead to treatment failure. Since the 1950s; conventional thinking has held that the cause of obesity is fundamentally the overconsumption of calories — we get fat because we eat too much and move too little. Virtually all research on obesity and its related chronic diseases is predicated on this notion that obesity is an energy balance disorder. Regrettably; treatments based on this logic — eating less and exercising more — have typically failed; suggesting the possibility that this energy balance hypothesis of obesity; simple as it seems; may be misconceived.

  • Translating Science Into Policy by Dr. Robert Lustig; MD

    Via a review of recent scientific literature; Lustig dispels a series of myths about chronic disease. The first myth is that chronic disease is about obesity. Lustig points to flaws in scientific research that appears to support this myth; noting; for instance; its confusion of correlation and concordance. He demonstrates that the data instead shows the problem is not obesity but all the metabolic diseases that attend obesity: diabetes; hypertension; lipid abnormalities; cardiovascular disease; nonalcoholic fatty liver disease; polycystic ovarian disease; cancer; and dementia.

  • An Alternative Hypothesis for Coronary Atherosclerosis by Dr. Vladimir Subbotin; MD; Ph.D.

    CrossFit Inc

    Subbotin presents an alternative hypothesis for CA pathogenesis; one that suggests an opposite route for the invasion of lipoproteins into the coronary tunica intima. While the commonly held belief; particularly among supporters of the lipid hypothesis; suggests lipids invade through the arterial lumen; Subbotin claims lipid deposits develop through the vasa vasorum.

  • Character; Self-Belief and the Search for Perfection: Psychology and Human Performance by Prof. Timothy Noakes; MD; D.Sc.

    Online Course | CrossFit Inc

    CrossFit Inc

    Prof. Timothy Noakes shares his hypothesis that self-belief ultimately shapes how an athlete will perform. In supporting his hypothesis; he draws examples from famous moments in sports history and describes the physiological changes that occur during sports competitions: “If you put two competitors against each other; the instant the one guy goes ahead; the other person’s physiology changes;” he explains. The brain regulates the exercise performance … the athlete who wins a close race chooses that outcome.
