In this segment, Eric Roberts explains how the hormone leptin regulates hunger and metabolism. He describes that low leptin signals the body to conserve energy and increase appetite, while a strategic “refeed” day—consuming a larger amount of food—temporarily raises leptin levels. This short‑term leptin boost makes a person feel less hungry, experience more energy, burn slightly more calories, and helps the body release stored “layer 2” fat. Roberts likens the process to reloading a weapon or pulling back a slingshot, emphasizing the amplified forward motion that follows the leptin increase.

And leptin is the hunger hormone that tells your body you're full and satisfied. When leptin is low, your body reads, we're running out, slow everything down, and increase hunger to get more food. But when you hit it with a refeed day, leptin increases, and for a brief period of time, you're less hungry, you have more energy, you burn a bit more calories, and your body starts to release the grip on that layer 2 fat. I think of it like reloading a weapon or pulling back on a slingshot to then have it go that much farther forward.
