Measure your metabolism throughout your fast for personalized recommendations. Begin by measuring your metabolism when you first wake up to establish a baseline and determine whether you’re burning carbs or fats for fuel.
Continue measuring your metabolism every hour. The goal is to remain at level 1 or 2, which indicates fat burn. During a fast, your mitochondria should be burning fat for fuel. When you shift towards carb burn (level 4 or 5), this indicates you should break your fast, as your glycogen stores are getting critically low and leading your body to break down muscle for energy.

Take a Lumen pre-workout breath measurement to determine if you should fuel up before your high-intensity workout. If you’re burning fat, that’s a sign your glycogen stores are low, and you should eat a fast-digesting carbohydrate source like a banana to avoid muscle breakdown.
Lumen’s fasting measurement is also helpful for maintaining muscle. You can find your ideal fasting window by measuring your metabolism throughout your fast. The moment your body shifts from fat burn to carb burn indicates you’ve passed your fasting sweet spot. That’s a sign to end your fast and eat something nutritious to avoid muscle breakdown.
Lumen also provides tailored macro recommendations based on your real-time metabolic measurements, so you get enough protein and carbs to build and maintain your muscles.
