Digestion takes energy.

Your body burns massive amounts of ATP to produce stomach acid, activate your pancreas, trigger immune responses, and absorb nutrients across 3,000 square feet of intestines. That's why big meals make you tired.

This is one of the reasons why if you eat a huge meal, you feel tired afterwards because every time you eat, you've gotta secrete enzymes. Stomach acid is a million times more acidic than blood. So it takes a lot of energy to move all those hydrogen atoms and, and configure them in such a way to produce the acid. You also have to then activate your pancreas. You have to release, you know, pancreatic enzymes and insulin and bile secretions. And of course, every time you eat, your immune system has to meet and greet every ingredient and every, you know, molecule before it enters into your bloodstream. So the immune system becomes activated in the process as well. And then of course we have to detox things out, so the liver becomes involved. And then of course the surface area of your bowel is 3,000 square feet. So now we're activating all of those cells. So digestion is, is a very metabolically expensive activity. So we wanna send as much energy to that system as we can. But if we're in fight or flight, we're kind of sending a competing message for that function. And so getting into a state of chill relaxation is very potent and powerful.
