Postprandial glycaemic dips predict appetite and energy intake in healthy individuals
Wyatt and colleagues used continuous glucose monitors on more than a thousand people across British and American cohorts, who ate thousands of standardised meals followed by tens of thousands of meals of their own choosing. The measure that predicted hunger was not the peak in blood sugar after eating, which is what most advice concentrates on, but the dip that follows it two to three hours later. People whose glucose fell furthest below their starting level at that point reported more hunger, ate sooner, ate more at the next meal, and ate more across the following day. The associations are modest in size but consistent across both cohorts. Because the dip differs between people eating identical meals, it offers a mechanism for why the same food leaves one person satisfied and another hungry. This vault cites it whenever the question is why hunger returns soon after a large meal.
