How to fight off post-lunch dip?

Fighting off the post-lunch dip involves a combination of strategies related to diet, light exposure, and activity:

1. Smaller Lunch: Consuming a smaller meal can reduce the physiological disturbances (like blood glucose and postprandial changes) that contribute to sleepiness after eating. This helps maintain alertness post-lunch 1 .

2. Bright Light Exposure: Bright light increases alertness. Having lunch outdoor or taking a short walk in natural light can help stave off the sleepiness that often comes after lunch 1 .

3. Meal Frequency and Composition: Eating fewer, larger meals rather than frequent small meals can be beneficial. This approach can minimize the constant insulin response and help avoid the postprandial dip. Ensuring your meals, particularly breakfast, are high in protein and fat can lead to longer satiety and better overall energy levels throughout the day 2 .

These strategies can collectively help manage and mitigate the common afternoon energy slump.
