Why Gluconeogenesis is Bad for Ketosis
The body’s preferred source of fuel is glucose, which it gets first from carbohydrates on a standard diet. However, if enough carbs aren’t present, which is the case when you’re eating low-carb or ketogenic, the body will have to turn to other sources for energy.
The purpose of the keto diet is to have the body break down fatty acids, which then produces ketones for energy—the process known as ketosis. Those following a ketogenic diet know that monitoring ketones in the body is how you know you’re in ketosis.
However, there’s another way the body can create carbohydrate-style energy in the body—by breaking down amino acids from the protein in your muscles. Gluconeogenesis (GNG) is how your body turns protein into glycogen that can be used as glucose to burn for fuel.
Why is this bad? There are two big reasons:
- When the body turns to protein for fuel, it keeps your body from going into ketosis. This stalls any long-term progress from the keto diet and you won’t reap the benefits that come from using ketone bodies for energy, burning through fat, and reducing your body’s reliance on carbs for fuel.
- Plus, it’s bad news when the body turns to your lean muscle mass for fuel. This isn’t good for your physique, or your physical performance, or your health.
