Food diary for beginners — keep it light
A food diary is just a record of what you ate. Digital food logs make that record useful for calories, macros, and habits — if you keep the process kind.

Paper vs app
Paper is reflective. Apps are searchable, chartable, and faster once your staples are saved. If your goal includes calories or macros, a digital food tracker wins on speed.
What beginners should write
Meal name, approximate portions, and time of day are enough. Add calories when you are ready. Notes about hunger or mood can unlock patterns later.
Avoid the all-or-nothing trap
Missed a lunch entry? Estimate it later. A food diary with honest gaps still teaches you more than a blank week after a “perfect streak” broke.

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.
