Short conversational clip from a YouTube video by Gary Brecka discussing the mismatch between carbohydrate intake and the body’s energy expenditure. Brecka asserts most people consume more carbs than they can use; when intake equals utilization there is homeostasis, when intake exceeds utilization there is imbalance. He also links living at altitude with lower oxidative stress and longer life expectancy due to matched oxygen intake/utilization. A second speaker emphasizes the same intake–utilization balance for endurance exercise and the need to refuel muscle glycogen.

Most people eat excessive carbohydrates, but they actually don't have the energy expenditure to burn those carbohydrates. It's all about intake and utilization. When intake meets utilization, you have homeostasis. When intake exceeds utilization, you have imbalance. People that live at altitude, for example, have a tendency to have longer life expectancies. Why would living in less oxygen give you a longer life expectancy? Because your oxygen intake meets your oxygen utilization, so you have less oxidative stress.
When you're doing endurance, you have to refuel, you have to fuel correctly for your muscles to work. You need the glycogen in the muscles for it to work. So it's exactly that, what you said, it's input and output. They should balance.
