One cup garbanzo beans (chickpeas)
45 grams of carbs minus 12.5 grams of fiber = 32.5 grams usable carbs
One cup Hummus, home prepared (whatever that means)
49.5 minus 10 = 39.5 grams usable carbs
One cup Hummus, commercial (whatever that means)
36 minus 15 = 21 grams usable carbs
One cup Soybeans, green
20 minus 7.5 = 12.5 grams usable carbs
HUGE difference between garbanzo beans and edamame (green) soybeans. There's also a big difference between different hummus recipes. But the only one that counts is the one you're eating. Regular hummus is too carby for a lowcarber, though it makes acceptable food for a moderate carber or someone allowing themselves a mild cheat.
Not only is the edamame version far less carby, but it has enough protein for a meal. Chickpea hummus has little protein (some, but not enough for a meal).
