What causes me to feel lethargic after eating?
Certain foods make you feel tired due to the various natural amino acids found in the food. Tryptophan, an amino acid found in foods such as turkey, chicken, nuts, milk, seeds, eggs and fish, stimulates the release of serotonin, a chemical which makes your feel calm, stable and happy while working to regulate your sleep patterns. After eating foods high in tryptophan, you might feel tired and lethargic as a result of the serotonin being released in your body.
