How we write and check our guides

By Replete · Updated October 19, 2026

Every guide on this site answers one question, links the sources behind its claims, and shows the date it last changed. Here's how we research and write them, where the numbers come from, and how to tell us if we got something wrong.

Sources come first

Any claim you could act on links to where it comes from: a systematic review, a trial, or an official body such as the World Health Organization, the NHS or the Dietary Guidelines for Americans. We read the source before we cite it, and we keep what we write inside what it found. When studies disagree, we say so. We don't use findings that were later retracted or failed to hold up, however often they're still repeated.

Where the figures come from

• Calories and nutrients in foods: USDA FoodData Central, the same data behind the app's fact cards and games.
• Sugar: when we count it, we mean free sugar as the World Health Organization defines it (sugar added to food, plus the sugar in honey, syrups and fruit juice), not the sugar in whole fruit or plain milk.
• Daily targets: the Mifflin-St Jeor equation for calories, and protein per kilogram of body weight from the current Dietary Guidelines, the same maths the app uses.

Amounts are given in both metric and US units wherever readers use both.

How we use AI

We use AI to help research and draft. Every page is then checked against its sources and read by a person before it goes up. A page doesn't go up if it can't add something useful to what's already out there.

What we won't publish

• Crash diets, very low calorie plans, or promises of how much weight you'll lose or how fast.
• Advice for medical conditions. If you have one, your doctor or a registered dietitian comes first.
• Vitamin, mineral or supplement advice.
• Quotes, reviews or credentials from people who didn't give them.

About the app

We make the Replete app, and our guides mention it where it helps. They never claim it does something it doesn't. When a guide names another app, it sticks to facts from a dated source.

Updates and corrections

The date at the top of a guide changes only when its content does. If you spot a mistake, write to support@replete-app.com. We'll check it against the sources, fix what's wrong, and say on the page what changed.

General information, not medical advice. If you have a health condition, are pregnant or take medication, check with your doctor or a registered dietitian before you change how you eat.
