Drinking Olive Oil on an Empty Stomach: What Does Science Say?

5 min read 2026-06-15Europe Olive Oil

Quick Answer

Yes — for healthy adults, a spoonful of extra virgin olive oil on an empty stomach can help: it stimulates bile secretion to prepare digestion, its oleic acid promotes fullness, and its natural lubricating effect may ease mild constipation more gently than chemical laxatives. Taken fasting, its polyphenols and vitamin E are absorbed without obstruction, protecting against oxidative stress. One tablespoon (about 15 mL) daily, 15–20 minutes before breakfast, is enough.

A Centuries-Old Mediterranean Habit

The morning spoon of olive oil that became popular on social media is not new. From Crete to the Aegean, Mediterranean peoples have started the day with extra virgin olive oil for generations. But is there a scientific basis for it?

Digestion and Gut Health

Taken on an empty stomach, olive oil stimulates bile secretion, preparing the body to digest fats. Its oleic acid slows gastric emptying and promotes a feeling of fullness.

For those with mild constipation, the natural lubricating effect of olive oil can help regulate bowel movements — a far gentler approach than chemical laxatives.

Antioxidant Absorption

The polyphenols (hydroxytyrosol, oleuropein) and vitamin E in cold-pressed olive oil are fat-soluble. On an empty stomach these compounds are absorbed without obstruction and protect against oxidative stress all day.

How and How Much?

  • 1 tablespoon (about 15 mL) per day is enough
  • Drink it 15–20 minutes before breakfast, at room temperature
  • Always choose 100% natural extra virgin; refined oils are low in polyphenols
  • Add a few drops of lemon if you like

Who Should Be Careful?

People with gallstones or a chronic condition should consult their doctor first. Olive oil is not a medicine but part of a balanced diet.
