Delayed dinnertime impairs glucose tolerance in healthy young adults

We investigated the relationship between mealtime delays of up to 3 hours and subsequent glucose fluctuations in healthy young adults. After assessing glucose responses using intermittently scanned continuous glucose monitoring devices (isCGM), the peak glucose elevation, and incremental area under the curve (iAUC) of postprandial glucose during certain intervals increased significantly when the time between lunch and dinner was delayed by 1 h or more. Our findings support the importance of improving irregular mealtime habits, such as late eating. AbstractTo explore the relationship between mealtime delays of up to 3  h and subsequent glucose fluctuations, healthy young adults were allocated to three delayed dinnertimes in randomized order. Participants consumed test meals for lunch and dinner. After assessing the glucose responses using intermittently scanned continuous glucose monitoring devices (isCGM), the peak glucose elevation, and incremental area under the curve (iAUC) of postprandial glucose during certain intervals increased significantly when the time between lunch and dinner was delayed by 1 h or more. Our results support the importance of improving irregular mealtime habits, such as late e ating.
