To master the switch, you must identify the chemical players. You are trying to shut down the "Sugar Burner" hormones and activate the "Muscle Protecting" hormones.
| THE ALLIES (WANT) | FUNCTION |
|---|---|
| Ketones (Beta-Hydroxybutyrate) |
The "Super-Fuel." It bypasses glucose pathways. It is muscle-sparing (anti-catabolic) and signals the brain to sharpen focus (BDNF). |
| Human Growth Hormone (HGH) |
The "Shield." Spikes 1200%+ during fasting. Its specific job is to prevent muscle burning when food is scarce. It says: "Burn the fat, save the chassis." |
| Adrenaline (Epinephrine) |
The "Spark." Mobilizes fat from cells into the bloodstream to be burned. |
| THE ENEMIES (AVOID) | FUNCTION |
|---|---|
| Insulin | The "Storage Key." As long as Insulin is high (from carbs/frequent eating), you CANNOT burn fat. You cannot open the loading dock. |
| Cortisol (Excess) |
The "Panic Signal." If you are stressed AND out of sugar, Cortisol triggers Gluconeogenesis (see below). It melts muscle to make sugar. |
