November 19, 2025 — For some time now, we’ve been pointing out that the obsessive demonization of dairy fat in dietary health guidance really doesn’t make much sense. Skim milk doesn’t taste as good as whole milk. The evidence for better health outcomes from reducing dairy fat consumption is flimsy. In fact, a dozen years ago, Walter Willett and […]
October 8, 2025 — As an article of faith, many people, even some who should know better, dispense advice that sweeteners are bad for metabolic health and weight management. They rely on observational evidence and theories about how they might have subtle effects to undermine health. But no direct evidence. Now, in Nature Metabolism comes a randomized controlled study to […]
September 14, 2025 — The attention economy has been getting a lot of, well, attention lately. In fact, the phenomenon is nothing new. People have been competing for the attention of Americans since the rise of cheap daily newspapers in the 19th century. But lately it seems that the quest to command attention is taking over more and more […]
July 18, 2025 — Retatrutide is that impressively potent obesity medicine that teased us with remarkable weight loss outcomes back in 2023. As we wait for pivotal phase three data (now due later this year), we wonder about the risk for muscle loss with a drug that has the potency of retatrutide. A new paper in Lancet Diabetes & […]
June 30, 2025 — Within a month, we expect that U.S. Dietary Guidelines will come out of the MAHA machine, looking like nothing that came before. Speculation is rife and the expectations are low that this new incarnation will be tethered to nutrition research. Writing in The Atlantic about HHS Secretary Robert Kennedy Jr. and the imminent issuance of […]
January 17, 2025 — Obesity is linked to many common diseases, such as type 2 diabetes, heart disease, fatty liver disease and knee osteoarthritis. Obesity is currently defined using a person’s body mass index, or BMI. This is calculated as weight (in kilograms) divided by the square of height (in metres). In people of European descent, the BMI for […]
January 6, 2025 — As an article of faith, it is easy to find advice to avoid sweetness in the foods we eat. Canada’s Food Guide, for instance, tells us that “regularly eating foods that taste sweet can lead to a preference for sweet foods.” This is a common presumption. It is one of the rationales we see for […]
October 23, 2024 — God bless the people who put their time into the Dietary Guidelines Advisory Committee. It fits the textbook definition of a thankless task. Years of work go into producing a scientifically sound set of recommendations for a new edition of dietary guidelines to emerge sometime next year. But no matter what those recommendations are, people […]
October 7, 2024 — Public discourse about nutrition and health seems to go through waves of fear. There was the fear of fat that began in the 1980s. In the early 2000s, that wave subsided and the fear of sugar and carbs swept us all up with a fever to count carbs and especially, grams of added sugars. Though […]
September 29, 2024 — Evidence is mounting linking ultra-processed foods (UPF) to risk of chronic disease. Typically, UPF are foods that are energy-dense, high in fat, sugar, and salt, low in fibre, and with a long shelf life. Examples include biscuits, chips, candy, instant noodles, mass-produced bread, sweetened breakfast cereals, ready-to-eat meals, and reconstituted meats. Dietary recommendations encourage people […]
