Why mid-afternoon is the perfect storm for boredom eating.
What the evidence says
- ”For some performance variables, and some individuals, there is a dip in performance during the midafternoon hours” — the post-lunch dip[1]
- The dip is ”a real phenomenon that can occur even when the individual has had no lunch and is unaware of the time of day”, and the review puts its origin no more firmly than ”has its roots in human biology, and may be linked to the size of the 12-hour harmonic in the circadian system”[1]
- ”Certainly exacerbated by a high-carbohydrate lunch”[1]
- Habit loops tied to time/place — stable contexts trigger automatic behavior[2]
- Blood sugar dips can trigger hunger and snacking urges — The study measured this after a 75 g oral glucose load in obese/overweight men, not after ordinary meals; the mechanism is a review’s proposal[3]
- Boredom eating is about seeking stimulation, not nutrition[4]
- Perfect storm for boredom eating[5]
