I’ve been practising intermittent fasting for a while now, but I always found it tricky to know if I was doing it right. See, fasting is all about timing and using your body’s natural energy stores efficiently, but without any concrete feedback, it’s easy to second-guess whether you’re getting the results you’re after. That’s where the Lumen device came in and completely changed how I approach intermittent fasting.
The Lumen device measures your metabolism through your breath and gives real-time insights into whether your body is burning carbs or fats for fuel. For anyone practising intermittent fasting, this kind of information is invaluable. It helped me fine-tune my fasting routine to ensure I was burning fat during my fasting window and optimising my carb intake on eating days.
Here’s how it worked for me.
How Lumen Fits into Intermittent Fasting
If you’re unfamiliar with intermittent fasting, it’s an eating pattern that alternates between periods of fasting and eating. Some people do 16:8 (16 hours of fasting, 8 hours of eating), while others prefer longer fasts or even alternate-day fasting. One of the goals of intermittent fasting is to switch your body into fat-burning mode during the fasting window, which is where the Lumen device came in handy for me.
Using the Lumen device every morning, I was able to measure whether my body was in a fat-burning state or still using carbs for energy. Lumen works by analysing the carbon dioxide in your breath, which can tell you if you’re burning fat (lower CO₂) or carbs (higher CO₂). This real-time feedback was crucial for adjusting my fasting schedule to make sure I was actually tapping into fat stores during my fasting period.
Lumen’s Real-Time Feedback Kept Me On Track
One of the biggest challenges with intermittent fasting is knowing when your body has fully shifted into fat-burning mode. Before using Lumen, I would simply guess, but the device’s morning measurements gave me clear, data-driven insights. If my Lumen score indicated I was still burning carbs, I knew I needed to adjust my diet or extend my fasting window.
For example, after a carb-heavy meal the night before, my Lumen reading in the morning would often show that my body was still in carb-burning mode. On those days, I extended my fast a bit longer until Lumen indicated that I had shifted into fat-burning. It helped me balance my macronutrient intake on non-fasting days to ensure I was fuelling my body efficiently without overloading on carbs.
Fine-Tuning My Fasting Windows
Thanks to the Lumen device, I learned that my body often took longer to switch to fat-burning mode than I originally thought. When I first started intermittent fasting, I followed the 16:8 schedule, but my Lumen readings showed that I wasn’t hitting fat-burning mode until well after the 16-hour fasting window. With this data, I extended my fasting window to 18 hours, which helped me achieve a better balance between carb-burning and fat-burning days.
This personalised insight is one of the biggest reasons I recommend Lumen to anyone practising intermittent fasting. It’s not a one-size-fits-all approach—Lumen tailors its advice based on your body’s real-time data, helping you optimise your fasting routine.
How Lumen Helped Me Break Through Plateaus
One of the most frustrating things about intermittent fasting is hitting plateaus. You can feel like you’re doing everything right—fasting, eating healthy, working out—and still not see results. That’s where Lumen really shone for me. By tracking my metabolism every morning, I could see patterns that I wouldn’t have noticed otherwise.
For instance, there were days when I thought I was in fat-burning mode, but Lumen showed I was still burning carbs. This allowed me to adjust my workouts or nutrition plan to get back on track. Whether it was extending my fast or tweaking my macronutrient intake, Lumen’s insights helped me break through those frustrating plateaus and continue seeing progress with my intermittent fasting.
Optimising Nutrition with Lumen
Another way the Lumen device enhanced my intermittent fasting routine was by helping me optimise my nutrition on non-fasting days. Since Lumen tracks whether your body is burning fats or carbs, I was able to adjust my diet accordingly. On days when Lumen showed that I was burning more carbs, I focused on lowering my carbohydrate intake and increasing healthy fats.
Likewise, if my body was burning fat, I knew I could incorporate more carbs into my meals without disrupting my progress. This balance helped me avoid the usual pitfalls of intermittent fasting, like feeling too sluggish or drained during workouts, while still making sure I was achieving my fat-burning goals.
The Lumen device has been a game-changer for my intermittent fasting journey. It gave me real-time data to fine-tune my fasting windows, adjust my macronutrient intake, and break through plateaus. By understanding exactly when my body is in fat-burning mode and when it’s burning carbs, I’ve been able to optimise my fasting routine in ways I couldn’t before.
