Prevalence of Optimal Metabolic Health in American Adults

Several guidelines for cardiometabolic risk factor identification and management have been released in recent years, but there are no estimates of current prevalence of metabolic health among adults in the United States. We estimated the proportion of American adults with optimal cardiometabolic health, using different guidelines. Data from the National Health and Nutrition Examination Survey […]

Association Between Obesity and Cardiovascular Outcomes

Do mendelian randomization data show that an association exists between obesity and cardiovascular outcomes? In this systematic review and meta-analysis of nearly 1 million participants, obesity was associated with type 2 diabetes and coronary artery disease but not with stroke. Obesity may increase the risk of subsequent diabetes and may contribute to cardiovascular outcomes and […]

Sitting Is The New Smoking

An alien visitor to our planet would be perplexed by modern human life, not least our relationship with physical exertion. After 6 million years of hunter-gatherer existence, humans can be observed sheltering in warm rooms, counteracting the tiresome effects of earth’s gravity by slouching on comfortable seats in front of glowing screens, being whisked effortlessly […]

Dietary Carbohydrates Impair Healthspan and Promote Mortality

It has been known since the 1930s that global reduction of food uptake, so-called calorie restriction, extends the lifespan of rodents, other model organisms, including rhesus monkeys, and possibly humans due to an interacting set of experimentally established mechanisms. By contrast and based on observational coincidence rather than prospective causality, dietary recommendations to maintain human health have […]

Translating the Basic Science of Nutritional Ketosis & Keto-Adaptation

An impressive body of scientific evidence over the last 15 years documents long term benefits of carbohydrate-restricted, especially ketogenic, diets. We now understand molecular mechanisms and why they work. Popular books and articles now challenge the advice ‘carbohydrates are good and fats are bad.’ Circa mid-19th century urinary ketones were identified in diabetics sealing their […]

All The Ways You’re Sabotaging Your Health by Overdoing It On Sugar

Sugar lurks in dozens of unsuspecting foods, from yogurts and salad dressings to juices and sauces. Even when sucrose — the popular form of table sugar is not present in a food item, sugar’s cousins fructose and dextrose can likely be found somewhere on the label. To truly avoid sugar, you’d also have to cut out simple carbohydrates, including the ones […]

The Straight Dope on Cholesterol

Cholesterol is one of the most misunderstood molecules in the human body. Much like fire, it can be an essential tool for life, if used properly, or a destructive force if allowed to run amok. In this presentation, Peter Attia will explain how the body creates, moves, and utilizes this vital molecule and how what […]

The Toll of America’s Obesity

Beyond the human suffering, diet-related diseases impose massive economic costs. Obesity rates in the United States continue to worsen. So, too, does economic inequality. Are these trends related? After remaining essentially flat in the 1950s and 1960s, the prevalence of obesity doubled in adults and tripled in children between the 1970s and 2000. According to new data from the Centers […]

Carbotoxicity

Modern nutrition is often characterized by the excessive intake of different types of carbohydrates ranging from digestible polysaccharides to refined sugars that collectively mediate noxious effects on human health, a phenomenon that we refer to as “carbotoxicity.” Epidemiological and experimental evidence combined with clinical intervention trials underscore the negative impact of excessive carbohydrate uptake, as […]
