Metabolic & WeightA Creatine-Industry Advisor Ran the Study Behind the 'Skip the Gym' Headlines
A new trial says creatine builds lean mass without exercise, and his own society's journal published it. The measurement it leaned on is the one creatine is known to inflate with water.
Nutrition & FoodThe Older Adults Whose 'Biological Age' Dropped Ate More Carbs and Kept the Meat
The omnivorous, low-fat, high-carbohydrate group showed the strongest drop. The keto-style omnivore group was the only one of four that didn't budge at all.
Metabolic & WeightThe Headlines Blamed Stress. The Data Blamed Belly Fat, Cigarettes, and Poverty.
In 488,079 UK adults, chronic inflammation tracked with a heart quietly remodeling into a smaller, stiffer pump. The loudest drivers were belly fat, cigarettes, and poverty. The paper points at a druggable inflammation pathway; its senior author discloses fees and grants from Bayer and Google's Cali
Metabolic & WeightCrash Diets Rewire Your Gut to Sabotage the Next One
In mice, transplanting the gut microbes of weight-cycled animals into healthy ones handed over the bingeing with them. Crash dieting reshapes the gut, and the diet industry keeps selling you the fix for damage its last plan made.
Nutrition & FoodMRI Found Fat Marbled Inside the Thigh Muscles of Heavy Ultra-Processed Eaters, and Calories Didn't Explain It
MRI scans of 615 adults found more fat marbled inside the thigh muscle the more ultra-processed food people ate, and the link held after adjustment for calorie intake, exercise, and fat intake.
CancerYounger Generations Are Testing Biologically Older, and Early Cancer Is Tracking the Gap
By a nine-marker blood panel, Americans born in the 1990s scored biologically older than those born in the late 1960s did at the same age, and Washington University researchers found that accelerated aging tracked a higher risk of early-onset cancer.
Metabolic & WeightThe Fast Every Type 1 Diabetic Is Warned Against Held Up in a Six-Month Trial
Thirty-two obese adults with Type 1 diabetes ate only between noon and 8 p.m. for six months. No rise in severe lows, severe highs, or ketoacidosis, and their HbA1c fell 0.46 points against the calorie-cutting group.
