Metabolic Flexibility

The main player behind health, weight loss, energy and longevity.

Metabolism is Life

It’s the process by which your body converts the food you consume into energy for immediate use or to be stored for later.

The key factor in your metabolism is metabolic flexibility.

Metabolic Flexibility is the ability of the human body to switch back and forth between fat and carbohydrates based on their availability.

The physiology behind metabolic flexibility

A high-functioning mitochondrial density enables burning more fat for energy.
High insulin sensitivity helps partition carbohydrates into muscle rather than storing as fat.

Measuring metabolic fuels: fats or carbs

Physiology range for the overall measured respiratory exchange ratio
Respiratory exchange ratio (RER)
The type of metabolic fuel in use such as fats or carbs and the ratio between them.
Respiratory exchange ratio (RER)
The type of metabolic fuel in use such as fats or carbs and the ratio between them.

What affects our body's metabolic fuel usage?

Benefits of metabolic flexibility

Better health
Easier weight loss
Optimized workout performance
Build lean mass
Better sleep
Stronger immune
system
Better weight maintenance
Consistent blood
glucose level
Feel energized and not sluggish

How can we improve metabolic flexibility?

Macronutrient manipulation
Low carb days decrease the insulin spike, thus improving insulin sensitivity, and deplete your body's carb stores, enhancing mitochondrial function. High carb days ensure your body's ability to use carbs for energy and keep hormones in balance.
Workout
Working out improves mitochondrial function, which makes you more efficient at burning energy. Working out with low glycogen/carb storage specifically, trains your mitochondria to burn more fat.
Time restricted eating
Time restricted eating or intermittent fasting depletes your body's carb stores which enhances mitochondrial function to burn more fat and increase insulin sensitivity.

How Lumen helps you to achieve Metabolic Flexibility

Lumen measures the C02 levels in your breath to interpret if your body is using carbs or fats for fuel.

Lumen 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. Lumen then uses these measurements to provide you with a flex score, showing you how flexible your metabolism is. The measurement is a comprehensive evaluation of your metabolism initially based on 4-8 weeks of measurements and other tracked metabolic factors to determine your flexibility.
