it has nothing to do with blood flow. it has to do with the insulin response from a calorie dense meal, especially those high in carbs. when serum glucose (blood sugar) elevates the body secretes more insulin to clear blood sugar. insulin is a storage hormone its purpose is to help the body metabolize sugars, proteins and lipids. when there is an excessive of insulin secreted and serum glucose levels fall to low the body goes into a hypoglycemic state (low blood sugar) which typically causes tiredness and hunger...

There are also elements in the food, like the amino acid L-tryptophan in turkey which regulates sleep. Other factors, such as alchohol, or simply overeating, will cause one to become sleepy -- overeating will require blood to be used for the digestive system.

If you eat a "heavy" meal, it tends to spike blood sugar because those meals normally have a high concentration of carbohydrate.
Your body counters this by spiking insulin levels.
The high levels of insulin make your blood sugar drop rapidly, leaving you tired. It basically is classical hypoglycemia, but it is short-term in non-diabetic people.

Because a large portion of your blood leaves the brain and goes to the intestinal tract to aid in the digestion of food.

Much of the blood rushes to the stomach muscles to digest all that food making you feel lazy and ready for a nap.

Most of the blood in their systems heads right towards the stomach to help aid in digestion.
