An adult who weighs 75 kg, so is targeting about 75 grams of protein intake per day, would only need to eat 833 grams of cooked chickpeas (which are 9% protein by weight) to get there. That is indeed a lot of chickpeas! But a lot less than you claimed, and you probably shouldn't be getting all your protein from chickpeas anyway.

You're probably talking about dry weight. My can says 6g protein / 130 g. I'm about 100kg and to hit the 1.6 g protein/kg I need 160g of protein. 6g/130g * 3500 g is 161 g of protein.

Two numbers from the USDA:

- Canned, drained and rinsed: 7g protein / 100g [1]

- Boiled: 9g protein / 100g [2]

Not sure what explains the discrepancy (though the second number is much older), but both are considerably higher than what your can says. Sure you aren't reading a per-serving amount?

Nope, here's the can:

Net weight (3.5 * 130g = 455g) includes the liquid, which you'd normally drain before cooking. The beans themselves are much more nutrient-dense.
