Product Summary

The Lumen is an expensive hand-held device that looks to make people more conscious of what they’re putting into their bodies on a daily basis. However, the price tag is a steep one; for just 6 months of use, you’re looking at paying close to $250 (and it obviously only goes up from there).

If you’re looking to figure out if your body is burning fat or carbs for weight loss purposes, you’ll likely really appreciate what this device has to offer. The connected app will tell you what type of food you should be eating that day based on what your body is currently using as fuel. I think that the app could offer more concrete food plans as a next updated step, but the simple suggestions and daily Flex Score are fun to see.
