About Define Healthy

A small dictionary of the words that keep coming up in everyday conversations about food, movement and rest, written in plain English.

What this site is

Define Healthy collects the vocabulary of ordinary wellbeing: words like fiber, satiety, NEAT or circadian rhythm that appear on food labels, in fitness apps, in magazines and in conversations at the dinner table, often without anyone stopping to say what they actually mean.

Each entry answers a few simple questions. What does the word mean? Where does it come from? How does it show up in daily life? And what do people commonly get wrong about it? The aim is not to tell you how to live, but to make the words clear enough that you can read everything else with a sharper eye.

Who it is for

Anyone who has nodded along to a word they were not quite sure about. You do not need a background in science. If an entry assumes knowledge it has not explained, that is a fault in the entry, and suggestions are welcome.

How it is made

Define Healthy is an independent project, written and maintained in spare hours. Entries are added gradually, a few each week, and revised when better wording or newer guidance comes along. There is no advertising, no sponsored content and no affiliate links.

The site deliberately keeps things simple: no accounts, no comments, no tracking, nothing to install. It is meant to load quickly on an old phone and read well on paper.

The way entries are researched and written is described on the editorial standards page.

What it is not

This is a reference for words, not a source of medical advice. Nothing here replaces a conversation with a doctor, pharmacist, dietitian or other qualified professional who knows your situation. If you have symptoms that worry you, please speak to one.
