Three-System Energy Model

Energy is not produced by a single system but is the product of three interconnected systems — gut, hormone, and immune — operating together. Energy is not produced by a single system in isolation but is the product of three interconnected systems: gut health, hormone health, and immune health. The three systems communicate with each other and with the brain continuously throughout the day. The gut, hormone, and immune systems are in continuous communication with each other and with the brain throughout the day. Understanding the three systems as being in constant dialogue, rather than functioning independently, is the foundational insight for addressing chronic low energy. The three-system model yields three practical intervention levers: what you eat, when you eat, and mind-body health. Food quality and composition support gut, hormone, and immune function together.
