Experimentell: 10 gastric bypass operated patients
3 different oils ingested at separate study days will be tested against each others ability to induce gut hormone secretion.

Ingestion of 13.15 g C-8 dietary oil providing 0.0216 mol of triglycerides.
Ingestion of 10.17 g tricaprylin providing 0.0216 mol of triglycerides.
Ingestion of 19 g olive oil providing 0.0216 mol of triglycerides.
