July 24, 2025 — For years, people living with obesity have been given the same basic advice: eat less, move more. But while this mantra may sound simple, it’s not only ineffective for many, it can be deeply misleading and damaging. Obesity is not just about willpower. It’s a complex, chronic, relapsing condition, and it affects around 26.5% of […]
June 2, 2025 — This is stunningly positive news. While many of us are debating the nuances and evidence for lifestyle therapy in obesity, a clever group of cancer researchers have gone out and proven its value for extending life in people with colon cancer. A well-controlled clinical trial of personal coaching for exercise showed that it reduced cancer […]
May 30, 2025 — To be sure, exercise has many benefits – including the widely accepted benefit of fitness and a longer life. But a new study of causal inference linking fitness to reduced mortality suggests those benefits have been exaggerated. The problem is an old one: Confounding. The senior author of the new study, Marcel Ballin, explains: “We […]
December 27, 2024 — Diet and exercise is a dominant concept in obesity care that’s in the midst of an identity crisis. In The Atlantic, Daniel Engber sums up one point of view, writing: “Ozempic killed diet and exercise. Doctors might be slow to admit it, but Ozempic and other GLP-1 drugs are making dieting and exercise obsolete.” While […]
October 21, 2024 — “We conclude that exercise and video gaming have differential effects on the brain, which may help individuals tailor their lifestyle choices to promote mental and cognitive health, respectively, across the lifespan.” This conclusion comes from a preprint published on PsyArXiv. Science, health, and lifestyle reporters got even more bold with their conclusions. For instance, the […]
February 29, 2024 — What could explain the observation that self-reports of exercise predict less of a benefit for men than women? In the Journal of the American College of Cardiology researchers nimbly leap to a conclusion that women get greater gains in mortality risk reduction from “equivalent doses” of physical activity. But would men exaggerate their self-reports? When […]
November 24, 2023 — What is the difference between exercise and physical activity? Does it really matter? A recent review in Current Nutrition Reports suggests that this is a distinction that makes a difference. Oxford tells us that exercise is “activity requiring physical effort, carried out to sustain or improve health and fitness.” But physical activity is “any form […]
July 20, 2023 — Obesity care is suffering from a blinding distraction – BMI and weight loss. It’s not hard to find critiques of this. The American Medical Association recently cautioned physicians against the misuse of BMI as a surrogate for health and obesity. PLOS One has a new paper telling us BMI may not necessarily increase mortality independently […]
February 24, 2023 — The headlines make us dizzy. “For a longer life, afternoon exercise may be best,” says the Washington Post. “Morning Workouts May Lower Your Risk of Heart Attack and Stroke,” according to Verywell Health. However, BBC offers yet another view with a headline saying, “Best exercise time may differ for men and women.” Despite the wild variations […]
February 17, 2023 — NAFLD – the accumulation of fat in the liver without excessive alcohol use – is one of the key reasons that obesity is a real and chronic disease. It is one of the common complications of obesity, and it is rising in parallel with obesity – most disturbingly in children. Of course, losing weight is […]
