Not Keto
Kidney Beans
13.70g net carbs per 1/2 cup cooked
Half a cup brings 13.7 g net carbs, which can eat up most of a strict 20 g daily limit in one go. Tasty as they are in chili, they are too starchy to keep around on keto, so swap in black soybeans for a similar texture with far fewer carbs.

Good to Know
Canned versions are the usual culprit for hidden carbs. Brands like Bush's Best baked-style varieties add brown sugar and molasses, which push the numbers higher than the plain figures above. If you ever use them for a non-keto meal, rinse canned beans well to cut sodium, and check the label, since chili-seasoned or baked options often sneak in sweeteners and starch thickeners.
Is Kidney Beans Keto? The Full Answer
Kidney Beans contains 13.70g net carbs per 1/2 cup cooked (20.30g total carbs minus 6.60g fiber). Half a cup brings 13.7 g net carbs, which can eat up most of a strict 20 g daily limit in one go. Tasty as they are in chili, they are too starchy to keep around on keto, so swap in black soybeans for a similar texture with far fewer carbs.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 69% of a 20g daily carb limit. If you are following a strict ketogenic protocol, reach for a lower-carb option instead.
Better Keto Swaps
At 13.7 g net carbs per half cup, these knock out most of a day's keto budget in one scoop. Black soybeans are the closest stand-in, holding roughly 1 g net carbs per half cup while keeping that hearty, starchy bite for chili or a taco bowl. Want the same firm texture without the carb load? Edamame works well at about 4 g net carbs per half cup shelled, and it brings a similar protein punch. Cooked mushrooms, around 1 to 2 g net carbs per half cup, can also bulk out a stew and soak up sauce the way beans do, with almost nothing on the carb side.
