03 / IN REAL LIFE

From number to plate.

This is for dry oats; water raises porridge weight without adding energy.

The oats are measured dry. In porridge, water changes weight without adding energy; milk, yogurt, nuts and sweeteners are separate ingredients.

A table helps you orient yourself; the plate you cook or order has its own ingredients and quantities. For a useful estimate, record what you know, correct what seems off and consider the meal in the context of your habits, without turning a number into a verdict.
