Take control of your metabolism

Many of the factors that impact your metabolic health are within your control and can be changed to improve your body’s metabolic flexibility, which is your metabolism’s ability to efficiently switch between using carbs or fats as a source of energy.

Each morning, you’ll breathe into Lumen to see the source of your body’s energy: fats or carbs.

Lumen trains your metabolism to use the food you eat more efficiently.

When your metabolism is more flexible, you are better able to burn fat instead of carbs, leading to weight loss. By focusing on metabolism instead of restrictive or unsustainable diets, Lumen helps you lose weight and keep it off for good with daily feedback.
