Discover what feeds your unique biology

The science of you is complicated. But we use it to make eating right simple.

The science of Habit

We take an evidence-based, integrated approach to nutrition.

Our nutrition solution is rooted in systems biology, which is about understanding the larger picture by putting the individual pieces together. We look at 60-plus indicators to better understand what your body craves.

Partnering with experts in the fields of systems biology and nutrition, we make sure that the connection between each test result, metric, and recommendation we make is backed by significant scientific evidence.


Our testing process

The Habit Challenge® Shake

To help determine the ratio of carbs, fats, and protein that may be best for you, you are given a metabolic challenge beverage that is nutritionally equivalent to a large American breakfast. A lab measures indicators in your blood using samples you collected at different points before and after you drank the shake. Your results show us how your body responded to carbs, fats, and protein during the testing process.


Your test
