Lumen’s handheld metabolism tracker is the ultimate intermittent fasting calculator, and here’s why:
Over the past few years, intermittent fasting has soared in global popularity, and for good reason.
It’s become a go-to strategy for those looking to shed fat, improve metabolic health, and even enhance cognitive function.
If you’re plugged into the online fitness community, you’ve likely seen influencers singing its praises on your For You page, or perhaps you’ve even tried it yourself.
When done correctly, intermittent fasting can be a game-changer. However, this is where things can get tricky.
With numerous approaches to fasting – whether it’s the 16/8 method, the 5:2 method, or even alternate-day fasting – figuring out the best approach for your body isn’t always straightforward.
Starting out, there are plenty of traps that are easy to fall into if you haven’t got the right information. Think overeating while breaking your fast, consuming the wrong foods, exercising without enough fuel in the tank, and so on.
Some people turn to an online intermittent fasting calculator to help them navigate the choppy waters, but the trouble is, they’re all one-size-fits-all.
Your body is unique, and so is your metabolism, so with any generic diet plan, there’s always going to be a margin for error.
Enter Lumen. Offering real-time insights into your body’s metabolic state, Lumen’s handheld device is the personalised intermittent fasting calculator helping people stay on track.

Building Metabolic Flexibility With Lumen’s Intermittent Fasting Calculator
Intermittent fasting is all about building metabolic flexibility – your body’s ability to efficiently switch between using carbohydrates and fats as its primary fuel source.
While fasting, you allow your body plenty of time to process your daily macros, lower insulin levels, and shift into a state of fat burn.
One of Lumen’s key benefits is that it helps you master that metabolic flexibility by offering timely advice on nutrition, building sustainable habits that lead to lasting results.
Track Your Progress Over Time
One of the biggest advantages of using Lumen’s metabolism tracker as an intermittent fasting calculator is its ability to keep tabs your progress.
With regular use, you can see how your metabolism is evolving over time and whether your body is becoming more efficient at burning fat.

Acting as the ultimate intermittent fasting calculator, it helps you understand exactly when and how to fast, and how to reach that next level you’ve been craving.
