Are you eating right?
Getting the right fuel for a workout is vital, and the way your body processes food is as important as what you eat. If you’re getting smart and serious about your training, a metabolism tracker may be the ultimate solution – a device like the Lumen (around $500) will analyse the way your body is working and provide appropriate advice.
Essentially, the Lumen combines a CO2 meter and flow rate sensor attached to a mouthpiece into which you inhale and exhale. It calculates the carbon dioxide concentration of your breath, which tells it what your metabolism is doing – specifically whether you’re burning fat or carbs. Tracked over time, you’ll build up a profile of when your body does what, and how effective your diet and workout plans are. The Lumen app will offer advice on how to change your workout patterns or on what you should be eating.
We’d also argue that Lumen’s digestion-tracking tech isn’t too far removed from the heart rate tracker on your watch. It’s been adopted by some serious athletes already, and it might just work for you.
