About the Project

Macro connects daily nutrition estimates with simple ingredient portions.

Purpose and scope

Macro is the public project name used on this site. Start with the home calculator to estimate targets and generate breakfast, lunch and dinner. Separate TDEE, protein, macro-ratio and per-meal tools explore individual parts of the calculation.

Editorial & Review Policy

This content revision was prepared by inspecting the calculation, food and storage code and consulting the sources linked in the methodology pages. Mathematical examples are covered by software tests. These checks are not professional nutrition review, and no medically reviewed claim is made.

Data and corrections

The food catalog stores USDA record identifiers, descriptions, weighing states and per-100-g values. A source link is not proof that every copied value has been independently reconciled. When investigating an error, record the page, ingredient state, expected result and reproduction steps; body information is not required to describe a website bug.
