Updated 2026-07-01By Chris RichardsAll terms

Definition

A food diary captures meals and snacks so patterns — and calories — become visible.

Definition

Whether paper or app-based, a food diary is a chronological log of intake. Modern food trackers turn that diary into calorie and macro feedback.

General nutrition information, not medical advice. Calorie and macro targets are estimates — talk to a doctor or a registered dietitian before changing your diet, especially if you are pregnant, managing a health condition, or have a history of disordered eating.
