Outside of eating more protein, upping your fiber is one of the most effective tools for reducing hunger and making weight loss so much easier. And one of the most fiber rich foods is a simple, inexpensive ingredient that you probably already have in your pantry — black beans.

Not to mention a large study found legumes (such as black beans) to be one of the most nutrient-dense foods in the world. It’s loaded with iron, folate, magnesium, and phosphorus to help prevent disease, boost energy levels, and promote healthy growth and development.

Key Ingredients
Black Beans
Out of all the beans, black beans have a lot going for them. They’re low glycemic load (meaning they don’t spike blood sugar very much), very high in key micronutrients to support longevity and health, and they tend to cause less bloating than other beans, like pinto or kidney.
To top if all off, black beans are dense in antioxidants, such as anthocyanins, that can protect cells from damage. Thanks to their dark outer layer, black beans tend to have significantly higher levels of these important antioxidants than other lighter colored beans.
I personally like to use homemade black beans to reduce bloating. But if you choose to use canned, just make sure to thoroughly rinse the beans for at least 30 seconds under running water. This helps to get rid of excess oligosaccharides that can cause bloating.

Lime Juice

Tips From The Nutritionist
Autumn Bates, CCN, MS, BS, CPT
Don’t be fooled by the high protein content of beans! Although beans technically are rich in protein, you don’t get the same perks from it as you do from complete sources like meat, fish, chicken, dairy, or tempeh. Always, always, always pair beans with 3-5 oz. complete protein for best weight loss and wellness perks.
FAQ’s
Not at all. Even my midwestern besties who hate spicy food love this dish. Poblano peppers are inherently mild and not spicy. But if you’re looking to up the heat, try subbing (or adding in) 1-2 jalapeño peppers.
It depends on how carb sensitive you are. Black beans are very high in fiber which helps to lower the blood sugar spike, making it generally a good option for most people even while losing weight. But test it out and see how your body responds. If adding black beans stalls your weight loss, then you might be too carb sensitive at the moment.
