About GetMacros.net

What this site is

GetMacros.net explains what protein, fat, and carbohydrates actually do in the body, how much of each you need, and what happens when you don't get enough — backed by calculators, a glossary, quizzes, and games for anyone studying or applying sports and nutrition science.

How articles are sourced

Every factual claim on this site is cited to a peer-reviewed study, a government or academic health agency (Harvard T.H. Chan School of Public Health, the National Academies, NIH, Mayo Clinic, Cleveland Clinic), or — for athlete and team nutrition stories specifically — established news reporting. Every citation used across the site is listed with a direct link on the Sources & citations page, so any claim can be checked against its original source.

Calculators use published, research-validated formulas (the Mifflin-St Jeor equation for BMR, Dietary Reference Intake activity multipliers for TDEE) rather than proprietary or unverifiable estimates — also documented on the Sources page.

What this site is not

This is educational content, not medical advice. Nothing here should replace guidance from a doctor or registered dietitian, especially if you have a medical condition or are making a major change to your diet.

Questions or corrections

If you find a claim that looks wrong or a citation that's out of date, the fastest way to verify it yourself is the Sources page — every reference links directly to its original source.
