Metabolic Flexibility is a new and unique concept, unlike the low fat, low carb, calorie counting programs you may have tried in the past. This concept—metabolic flexibility— is based around the new science of how your metabolism works to burn more fat and perform at a higher level.

<aside> 💡 Simply put, it's your body's ability to switch efficiently between using carbs and fats as a fuel source.


See our Lumen video about it:

Lumen measures the C02 levels in your breath to interpret if your body is using carbs or fats for fuel. Lumen then provides you with a daily measurement of your source of energy: fats or carbs on a scale of 1 to 5, based on your RER.

We then use these measurements to provide you with a flex score, showing you how flexible your metabolism is.

The benefits of metabolic flexibility

Research (Calcada et al, Gormsen et al) finds that metabolic flexibility has a profound role in assessing a person's health.

Using the Right Fuel at the Right Time

****Metabolic Flexibility enables you to 1️⃣ transition between fats and carbohydrates so you can burn more fat when you're not exercising; and 2️⃣ use carbohydrates when you are exercising to fuel that activity and perform at a higher level.

This flexibility is the transitioning back and forth between fats and carbohydrates.
