Early Dinner Improves Blood Sugar Levels And Boosts Metaboli
Early dinner at (at 18:00) versus late dinner (at 21:00) has a positive effect on blood sugar level fluctuation and substrate oxidation, according to a recent study in the journal Nutrients. Researchers aimed to examine whether mild early time-restricted eating (eating dinner at 18:00 vs. at 21:00) improves 24-h blood glucose levels and postprandial lipid metabolism in healthy adults in a randomized crossover study.

The study included 12 participants (10 females and 2 males). Two different conditions were tested: eating a late dinner (at 21:00) or an early dinner (at 18:00). During the experimental period, blood glucose levels were evaluated by each participant wearing a continuous blood glucose measuring device.

Using the indirect calorimetry method, metabolic measurements were performed on the morning of day 3. The study was conducted over three days; day 1 was excluded from the analysis to adjust for the effects of the previous day's meal, and only data from the mornings of days 2 and 3 were used for the analysis.

Key findings of the study include:

• Significant differences were observed in mean 24-h blood glucose levels on day 2 between the two groups.

• There was a significant decrease in the postprandial respiratory quotient 30 min and 60 min after breakfast on day 3 in the early dinner group compared with the late dinner group.

"Our findings show that despite the difference of only 3 hours, early dinner compared to late dinner resulted in a greater iAUC for blood glucose levels after dinner, higher average blood glucose levels the following day, and higher average blood glucose levels from evening to early morning (18:00 to 6:00)," wrote the authors. "There was no difference in respiratory quotient before breakfast between the groups, but the early dinner group exhibited a lower respiratory quotient after breakfast and increased lipid oxidation compared with the late dinner group."
