Portions, and the two kinds of cooked

Most foods come with household measures: a tablespoon, a stick, a large egg, an 8 oz steak. Tap one and the amount fills in. Quantity multiplies whichever one you picked, so three chops is one tap after the first.

Some entries say "(avg)": a chicken breast, a scoop of protein, a bar. Those vary widely in real life. The number still beats eyeballing, and the label is there so you know not to trust it to the gram.

RAW OR COOKED, first meaning: when a food's name doesn't say how it was prepared, you pick which weights to show. A breast is 174 g raw and 140 g cooked. This changes the portion weight only.

RAW OR COOKED, second meaning: when a food's name says raw and you weighed yours after cooking, tell it so. Sigma scales the numbers by the USDA yield for that food, states the percentage on screen, and converts the name to "cooked (est.)" so your log doesn't claim you ate it raw.

Watch the line under the number when you switch. Choosing cooked at 16 oz does not re-describe your steak; it claims a bigger one, about 22 oz raw. The line says so before you log it.
