What Are Lupini Beans?
Lupini beans are a type of yellow legume traditionally eaten in Mediterranean countries such as Italy, Spain, and Portugal.
They’ve been consumed for thousands of years, often served as a salty snack in bars and cafés.
Unlike most beans, lupini beans have a unique nutritional profile that makes them suitable for low-carb and ketogenic diets.
They are often sold:
Pre-soaked in jars
Brined like olives
Ready to eat as a snack
Many people simply pop the bean out of its skin and eat it.
Lupini Beans Nutrition (Why Keto Dieters Love Them)
One reason lupini beans are exploding in popularity is their exceptional macro profile.
Typical nutrition (per 100g):
Calories: ~120 kcal
Protein: 16g
Fiber: 16g
Net Carbs: Very low (often near 0g)
Fat: 2–3g
Because they contain so much fiber, the net carbs are extremely low.
This means lupini beans can:
✔ Help control hunger
✔ Support muscle maintenance
✔ Prevent keto snack cravings
✔ Keep blood sugar stable
Many keto dieters even call them “the bean that behaves like a nut.”
How to Eat Lupini Beans Properly
If you've never eaten lupini beans before, they can be slightly confusing.
Most varieties come with a thin yellow skin.
To eat them:
Hold the bean between your fingers
Pinch one end
The bean pops out of the skin
Eat the inside and discard the shell
They are commonly enjoyed:

With olive oil
They are also fantastic as a keto snack replacement for chips or peanuts.
