Please read: Cooked bean variety.
The "beans in your pantry" data you're looking at are probably per serving. Here, let me grab the beans in *my* pantry. Roland BLACK BEANS Habichuelas Negras Supreme Calidad. Net weight 15.5 OZ / 439g. Serving size: 130g. Calories per serving: 180.
There's 453,6 grams per pound, so that's 0,968 pounds. 439/130 = 3,15 servings, times 180 calories = 567. In 0,968 pounds, that's 586 calories.
Or look online. "172 grams of black beans (cooked, boiled, unsalted) contains 227 Calories." Do the math.
I'm not sure exactly how you expect something that is 70% carbs (of which are 36% fibre) and 26% protein to be low-cal. Do you think it has the moisture content of celery or something?
