a satiety booster. Exceptional fullness per calorie — but at only 17 kcal per 100 g, it can't fill you up on its own. Its power is making a meal bigger and more filling at almost no calorie cost; pair it with protein.

Why this score
The first three bars are sub-scores (0–100 per lever) that build the score; the values under each label are the measured quantities that drive them. Hyper-palatability works the other way — it cuts the built score by the shown percentage (up to −80%). Full math here.
