Protein
Understand. Record. Prepare.
Log protein without losing track of serving size.
AI-created editorial illustrationFood weight versus protein amount
A 150 g portion of food does not contain 150 g of protein. The nutrition label gives protein for its specified serving, while a scale gives the total weight of the food. Matching these two quantities is the first step before comparing products or adding a meal to a diary.
A protein entry combines the food, its preparation, the portion, and the amount of protein attributed to that portion. Grams of food and grams of protein describe different things. The quality of a total depends on choosing a source that matches what you actually ate.
Here you can learn how to handle serving sizes, scale a label with the protein portion calculator, and keep a food record. Protein Tracker+ adds database and reporting features; this hub does not calculate a personal daily protein target.

Count protein in a mixed meal without duplicate ingredients
Choose a whole-meal entry or an ingredient breakdown, then check toppings, sauces and additions so your protein record does not count them twice.
Compare protein labels on the same serving basis
Resolve different protein numbers on the front and back of a package by checking per-serving, per-container and per-100-gram quantities.
A protein log that keeps portions and grams straight
Distinguish the weight of a food from the grams of protein it contains, then use one consistent record format.

Protein 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.
Protein amount = label amount × portion eaten ÷ label portion.
Check the label wording and units before using the result. Estimates remain estimates.
