Everything on this site comes back to one idea. Here's the short version, in plain English, before you go deep on any single pillar.
Acute inflammation is the redness and swelling around a cut or a sprained ankle. It's useful — it's your body healing itself, and it resolves in days.
Chronic, low-grade inflammation is different. It's a slow, background hum your immune system runs for weeks, months or years — often driven by diet, poor sleep, excess alcohol, inactivity and chronic stress. You usually can't feel it directly. You feel its side effects: fatigue, brain fog, joint aches, skin flare-ups, poor recovery and a general sense of running at 70%.
This second kind is what THE FAD Score is trying to estimate every day.
Why calories miss this entirely: a calorie is a unit of energy. It says nothing about whether the food carrying that energy is calming your system down or winding it up. Inflammation is a quality signal, not a quantity signal.
THE FAD Score is built from five categories. Each has its own deep-dive page — this is the map.
Sugar, ultra-processed foods, vegetables, protein, fibre, omega-3s, meal timing.

Read more →An educational, self-tracking tool that estimates your day-to-day inflammatory load from lifestyle inputs, so you can spot the patterns that make you feel amazing or terrible.
A medical device, a diagnostic test, or a treatment for any disease. It doesn't replace a doctor, and it can't measure your actual blood biomarkers — for that, ask your clinician about a test like hs-CRP.
Our approach draws on published nutrition and sleep science, plus the public work of researchers and longevity-focused public figures.
