How Intermittent Fasting Works on Insulin
The Science Behind Meal Timing
In this section, the Jason Fung fasting YouTube content explains how reducing eating windows lowers insulin spikes. By compressing meals into specific hours, many viewers experience improved insulin sensitivity and reduced hunger between meals.
Fung often highlights that the goal is not just calorie reduction, but aligning eating with periods of low insulin to access stored body fat. This physiological shift supports gradual, sustainable changes rather than abrupt crash dieting.
