The CrossFit stimulus—constantly varied high-intensity functional movement coupled with meat and vegetables, nuts and seeds, some fruit, little starch, and no sugar—prepares you for the demands of a healthy, functional, independent life and provides a hedge against chronic disease and incapacity. This stimulus is elegant in the mathematical sense of being marked by simplicity and efficacy. The proven elements of this broad, general, and inclusive fitness, in terms of both movement and nutrition, are what we term our CrossFit Essentials.

Eleven women following a ketogenic diet showed dramatic improvements in diabetes and heart disease markers, experiencing substantial weight loss and dramatically decreased HbA1c, over a period of 90 days. When compared to existing therapies such as insulin secretagogues, this study suggests the ketogenic diet is both more efficacious and has fewer negative side effects than pharmacological alternatives for diabetes treatment.

The thoracic segment of the body is home to the thoracic vertebrae, the ribs (costals), and numerous muscles that move the vertebral column, ribs, and structures attached to the thoracic skeleton. Deep muscles that arise and act primarily within the thoracic generally have contractile functions in respiration (breathing) and maintaining vertebral column posture.

Previously in this series, Prof. Tim Noakes argued Dr. Gerald Reaven was on the brink of discovering the optimum treatment for insulin resistance syndrome, a condition he called “Syndrome X.” In this post, Noakes delves further into the scientific literature available to Reaven as he formulated dietary recommendations for patients with the condition. The prevailing theory at the time suggested carbs were an essential part of a healthy diet and cautioned that the consumption of saturated fats would promote heart disease. Tragically, despite the contrary indications of his own research and a growing body of evidence revealing the detrimental effects of carbohydrate ingestion in persons with insulin resistance or Type 2 diabetes, Reaven ultimately bowed to the influence of Keys and other diet-heart hypothesizers and promoted a diet closer to that recommended by the American Heart Association — a diet Noakes argues has caused the rates of obesity and Type 2 diabetes to soar around the world.

The fitness that CrossFitters demonstrate cannot be found without ring training. Gymnastics rings occupy a place in our training that only the barbell can match. Kettlebells and dumbbells, medicine balls and stretch bands, while essential to our practice, are second-tier tools to the rings.

A new meta-analysis of large observational studies suggests reducing red or processed meat intake has little to no effect on mortality. Researchers used the GRADE methodology to evaluate 61 large cohort studies assessing the relationship between red and/or processed meat intake and cardiovascular or all-cause mortality. They found the evidence supporting any association between red and/or processed meat and cardiovascular or mortality outcomes to be of a consistently low quality and suggest that if reducing red and/or processed meat has any impact on mortality, the impact is very small.

This 2001 review analyzes the significance of a particular lipoprotein profile, hypertriglycermidemic hyperapoB, which is strongly correlated with diabetes and heart disease risk. The authors posit small, dense LDL particles increase diabetes and heart disease risk, and form as a consequence of insulin resistance. Accordingly, dietary and lifestyle factors that increase liver fat content and insulin resistance may increase heart disease risk, even if they do not impact total or LDL cholesterol.

Dr. David Diamond, a Ph.D. in biology and neuroscientist with 40 years of experience, speaks about cholesterol science and the various forms of deception apparent in research on cholesterol-lowering statins. Diamond developed an interest in cholesterol and statins in 1999 after being diagnosed with familial hypertriglyceridemia, a genetic anomaly that causes triglyceride levels in the blood to become elevated, leading to additional health complications such as obesity. After realizing that the dietary and pharmaceutical recommendations he was given were all wrong, Diamond began to investigate the sources of the misinformation. In this presentation, he shares how his discoveries conflict with received wisdom about cholesterol and statins and explains how and why we have been deceived by companies that seek to profit from our ignorance.

This highly cited 1998 review links insulin resistance to increased heart disease risk. Dr. Scott Grundy, the review author, observed the “lipid triad” of high triglycerides, small LDL particles, and low HDL is common among those with metabolic syndrome and insulin resistance. These conditions may also be mechanistically linked. Insulin resistance leads to increased liver fat, which increases fat VLDL production — in other words, insulin resistance may directly cause the lipid triad.
