Food & calories
Understand. Record. Prepare.
Build a food record with clear portions and honest estimates.
AI-created editorial illustrationEnergy amounts depend on the serving
A calorie value describes the energy associated with the labeled portion. It is not a grade for a meal or a measurement of your personal energy needs. A larger or smaller portion changes the arithmetic, while a guessed portion leaves uncertainty that should stay visible in the record.
A food diary can be useful even when portions or energy values are uncertain. Describing what you ate, how much you remember, and where an estimate came from preserves more context than an unexplained exact-looking number. Calorie amounts are optional in the free log.
This hub includes a guide to estimated portions, a label portion calculator, and a meal log. BiteSync adds food search, custom items, barcode/photo features, and reports according to its listing. A photo estimate is not a direct measurement, and this website does not set a weight-loss target or grade meals.

Energy portion calculator
Scale the label amount to the portion you ate. Both portion quantities must use the same unit and preparation basis. The result is record arithmetic, not an intake target.
Energy amount = label amount × portion eaten ÷ label portion.
Check the label wording and units before using the result. Estimates remain estimates.
