Should chicken breast be weighed raw or cooked?

The chicken breast rows exist in more than one state because water moves during cooking: this is the raw row. Weigh the food in the state you log and pick the row that matches — the calories don’t change in the pan, the grams do. The mechanics are in cooked vs raw weights.

Worth knowing

This is the row a recipe means by "6 oz of chicken breast". Cooking drives off about a quarter of the weight as water, so 100 g raw becomes roughly 75 g cooked with the same calories — which is why the cooked row reads higher per 100 g.
