|So that's what gold medal swimmers eat|
The article quotes Prof. Catia Martins as saying:
Exercise “improves the body’s ability to judge the amount of calories consumed and to adjust for that afterward”Now this doesn't mean that walking doesn't achieve the same goal, but it does shed light on how the body helps to regulate calorie consumption. This leaves us with an interesting theory of hunger dynamics: a body at rest tends to eat more than if that same body was up and moving. One way to help cure a case of the munchies is to get up and get moving.
