“If the gut bacteria get the right kind of fuel, they send messages to the brain that you are happy3and we don’t have to go find extra food.” However, when gut bacteria don’t get adequate nutrition, the brain sends out an SOS signal, saying it needs energy fast. The quick fix is usually sugar.
But one thing that’s much better for gut health, Gundry says, is prebiotic fiber—an indigestible fiber that nourishes beneficial gut bacteriastop cravings.
Foods rich in prebiotics include nuts, bananas, oatmeal, and apples. “mct oil it also feeds the gut bacteria,” Gundry adds. “It is a fat that is absorbed directly from the intestine into the blood and liver. From there, it’s converted into ketones that provide fuel for the brain.”
