Dr. Malcolm Kendrick discusses recent concerns in the medical community regarding the potential for bias in clinical research on statin therapy. He reviews the various reasons statin trials may be unreliable, including selective publication of results and strategic shifting of trial endpoints during ongoing studies. Despite the apparent evidence-based support of statin therapy and measures taken in the 1990s and early 2000s to mitigate bias, Kendrick urges doctors to proceed with caution when recommending the drugs. Echoing another review from 2015, Kendrick claims “a complete reassessment [of their efficacy and safety] is mandatory.”Read MoreStatins — Are the Data Free From Bias?

"Heartburn, ulcer and acid reflux medicine may bring relief, but over time, they could also increase a person's risk of early death, new findings show. Researchers have linked popular drugs like Prevacid, Prilosec, Nexium, Protonix and other proton pump inhibitors to a higher risk of death by cardiovascular and chronic kidney disease, as well as upper gastrointestinal cancer, according to a study published in The BMJ. More than 15 million people are prescribed PPIs each year, while millions more purchase them over-the-counter, the researchers say."Read the article Overuse of heartburn drugs linked to heart, kidney disease, cancer
Scientists continue to discover evidence of the therapeutic value of nutritional ketosis for a range of conditions, including Type 2 diabetes, Alzheimer’s, and cancer. Dr. Dominic D’Agostino, an Associate Professor of Molecular Pharmacology and Physiology at the University of South Florida, is at the forefront of research related to the use of ketosis for cancer treatment. During a presentation on July 31, 2019, at the annual CrossFit Health Conference in Madison, Wisconsin, D’Agostino shared his knowledge of the health benefits associated with ketones and presented his latest research on ketosis as an adjuvant treatment for high-grade glioma.Watch Dr. Dominic D’Agostino: Emerging Applications of Nutritional Ketosis

"The sound of cheering carried across the Alliant Energy Center as the top athletes from over 100 countries took the field Thursday during the 2019 CrossFit Games opening ceremony. Amongst a sea of U.S. competitors, Lt. Col. Anthony Kurz and Capt. Chandler Smith took it all in as they looked around the crowded North Field. Kurz proudly displayed his Army Special Forces flag as a nod to the Special Forces community. Those cheering included members of the U.S. Army Recruiting Command and Warrior Fitness team who were there to support their teammates and engage with the fitness community."Read the articleSoldiers Vie in Survival of the Fittest at 2019 CrossFit Games
Complete as many rounds as possible in 15 minutes of:
15 body-weight deadlifts
Post rounds completed to comments.
The deadlift is unrivaled in its simplicity and impact while unique in its capacity for increasing head to toe strength. Regardless of whether your fitness goals are to “rev up” your metabolism, increase strength or lean body mass, decrease body fat, rehabilitate your back, improve athletic performance, or maintain functional independence as a senior, the deadlift is a marked shortcut to that end. The deadlift’s primal functionality, whole-body nature, and mechanical advantage with large loads suggest its strong neuroendocrine impact, and for most athletes the deadlift delivers such a quick boost in general strength and sense of power that its benefits are easily understood. If you want to get stronger, improve your deadlift.Read the 2003 CrossFit Journal articleThe Deadlift
"The US military has been looking at changing the diets of elite operators like Navy SEALs as new evidence emerges that their diet could enhance their abilities on the battlefield, especially underwater. … The ketogenic, or keto, diet, is high in protein and fat and very low in carbohydrates. The diet forces the body to go into ketosis, in which the body burns stored fat, or ketone bodies, as energy instead of blood sugar, which comes from carbohydrates. Research shows the ketogenic diet can help human bodies stay underwater for longer periods of time."Read the articleNavy SEALs are looking into the keto diet to be even more effective on missions

Statins are the most widely prescribed class of drugs in the world and thought to be beneficial for reducing cardiovascular events and relatively risk-free. Dr. Malcolm Kendrick approaches such ideas with skepticism, here reviewing the research behind such claims and sharing the sleight-of-hand tactics used to promulgate them. While much of the data related to statin studies remains hidden from independent researchers, Kendrick finds that available data has been framed in misleading ways. Reviews of studies that tout statins’ effects on mortality reveal statistically insignificant outcomes and leave open the possibility that adverse events could offset statins’ very minuscule benefits.Read MoreStatins — What Are the Benefits?

Listen to Maurice Ravel, Miroirs, pièce III, “Une barque sur l’ocean.”
“I think there is a vast myth that scientists are somehow objective and honest,” Dr. Terence Kealey said during a presentation at a CrossFit Health event at CrossFit Headquarters on March 9, 2019. During his presentation, Kealey discussed the myth of scientific objectivity, drawing examples widely from history as well as his personal experiences within many of the most reputable scientific institutions. “We commit to paradigms, and then we bend the data to it,” Kealey explained. “Now, you get money not for being right; you get money for satisfying the prejudices of the people who sit on the committees in the NIH and NSF.”Watch Dr. Terence Kealey and the Myth of Scientific Objectivity
