Why Do People Feel Tired After Eating?

Post-prandial somnolence, or the post-lunch dip or food coma, is the feeling of sleepiness after eating.

Researchers have identified various factors that may contribute to wanting to sleep after eating, including:

  • Eating meals that are high in either carbohydrates or fat is more likely to make you tired than meals high in protein
  • Eating many calories in one sitting is also linked to post-meal fatigue
  • The timing of meals can impact energy levels
  • Research shows that consuming specific nutrients such as tryptophan, melatonin, and other phytonutrients promotes sleepiness

Other causes of post-prandial somnolence can include:

  • Underlying health conditions
  • Diabetes
  • Hypoglycemia
  • Anemia
  • Thyroid problems
  • Low blood pressure
  • Medications
  • Mild dehydration

Although you may not be able to avoid feeling drowsy after eating, there are some things you can try to counteract it, including:

  • Eating well-balanced meals
  • Getting more sleep at night
  • Exposing yourself to enough daylight
  • Getting regular exercise
  • Napping for 10-20 minutes

Feeling tired after eating is a normal phenomenon that most people experience. However, if the fatigue interferes with daily life and responsibilities, talk to your healthcare provider as it could be a sign of an underlying medical condition.
