Betts: How time-restricted eating may shift hunger and metabolism in healthy adults
Constant eating throughout the day may contribute to modern metabolic problems in some people. A daily eating window of 10 to 12 hours may help the body cycle between absorbing food and drawing on its own reserves, support insulin sensitivity, and quiet background hunger. Strict zero-calorie fasting is a separate, more advanced step.
