Beans are a powerhouse of nutrition, celebrated for their high fiber content, plant-based protein, and array of essential vitamins and minerals. For those managing their weight or simply aiming for a healthier diet, identifying the lowest-calorie options is a key step. While many factors influence the exact calorie count, this guide focuses on general averages for common, cooked bean varieties to provide a clear comparison.
The Top Contenders for Lowest Calorie Beans
To find which bean has the lowest calories, we need to compare a few of the most popular and widely available options. It's important to remember that these figures can vary slightly depending on the source, growing conditions, and cooking process. The following data is based on approximately a 1/2 cup (100g) serving of cooked beans:
- Green Beans: Often considered a vegetable, fresh or boiled green beans are remarkably low in calories, with a 100g portion having approximately 31 calories. Their high water content and low carbohydrate count make them one of the most calorie-efficient choices.
- Fava Beans: Cooked fava beans offer a low-calorie profile, with around 110 calories per 100g serving. They are also a good source of protein and fiber, contributing to feelings of fullness.
- Mung Beans: With approximately 106 calories per 100g cooked, mung beans are another excellent low-calorie option. They are a rich source of nutrients and are often used in a variety of cuisines.
- Kidney Beans (Light Red): At around 112 calories per 100g cooked, light red kidney beans are a solid, low-calorie choice that provides significant fiber and protein.
The Lowest of the Low: Green Beans
While mung beans, fava beans, and kidney beans are all great low-calorie options, green beans take the crown. Their placement as a vegetable rather than a mature, dried legume like the others is key. They are typically eaten fresh or lightly cooked, which contributes to their low-calorie density. For someone looking to maximize volume with minimal calories, green beans are the clear winner.
Nutritional Comparison of Popular Beans
Beyond just calories, it's beneficial to compare the overall nutritional content. This table shows a side-by-side comparison of different cooked beans per 1/2 cup (approx. 100g) serving.
| Bean Type | Calories | Protein (g) | Fiber (g) | Notes |
|---|---|---|---|---|
| Green Beans | 31 | 1.8 | 3.2 | Highest water content, lowest caloric density. |
| Fava Beans | 110 | 8 | 5 | Good source of protein and fiber. |
| Navy Beans | 140 | 8 | 11 | High in fiber, promotes satiety. |
| Adzuki Beans | 128 | 8 | 7 | Nutrient-dense with a slightly sweet flavor. |
| Black Beans | 132 | 9 | 9 | Rich in antioxidants, fiber, and iron. |
| Chickpeas | 164 | 9 | 8 | Versatile for hummus, salads, and more. |
| Lentils | 148 | 9 | 8 | Quick-cooking and high in plant-based protein. |
How Preparation Influences Calorie Content
It is crucial to consider how beans are prepared, as this can dramatically change their caloric load. A cup of baked beans in a sugary sauce, for instance, will be far more calorific than plain boiled beans. For weight management, choosing methods that don't add extra fat or sugar is key.
- Boiling or steaming: Cooking beans in water is the most direct way to prepare them without adding extra calories. For green beans, this is a standard method.
- Canning: Canned beans are convenient but often contain added sodium. Always rinse canned beans thoroughly to remove excess salt. The calorie count itself is not usually affected significantly.
- Adding fat or sugar: Many traditional bean dishes, such as baked beans or refried beans, incorporate significant amounts of fat, oil, or sugar, which increase the calorie content. A simple low-calorie baked bean recipe can still be delicious and healthy.
Conclusion
While green beans are technically the lowest-calorie option due to their high water content and classification, several other mature legumes offer impressive nutritional value with a moderate calorie count. For dishes that require the heartiness of a true bean, options like mung beans, kidney beans, and fava beans are excellent low-calorie choices that provide protein and fiber. Ultimately, the best bean depends on your dietary needs and the specific dish. For weight loss, focusing on how you prepare the beans is as important as the type of bean you choose. Opting for simple cooking methods and avoiding calorie-dense additions will allow you to enjoy all the health benefits beans offer without undermining your diet goals.

Frequently Asked Questions
Q: Are edamame beans low in calories? A: Yes, cooked edamame is a good low-calorie option. A 1/2 cup (100g) serving of shelled, cooked edamame contains approximately 120 calories, alongside significant protein and fiber.
Q: How does preparation affect the calorie count of beans? A: The way beans are prepared can dramatically change their calorie content. Cooking from dry by boiling will add almost no extra calories, whereas methods involving added fats, sugars, or oils (like in many baked bean or refried bean recipes) will increase the total caloric value.
Q: Are canned beans as healthy as dried beans? A: Canned beans are a healthy and convenient option, but they often contain added sodium. Rinsing them thoroughly before use is recommended. When prepared without additional fats or sauces, dried beans offer the same nutritional benefits without the extra sodium.
Q: Which bean is best for weight loss? A: While several beans are low in calories, the best choice for weight loss is subjective. Beans high in protein and fiber, like navy beans, black beans, or lentils, can help you feel full longer. The best option is one you enjoy and will regularly incorporate into your diet.
Q: What about lentils? Are they lower in calories than most beans? A: Cooked lentils are very competitive in terms of calorie content, providing around 110-116 calories per 1/2 cup (100g) cooked, similar to many low-calorie bean varieties. They are also quick to cook, versatile, and packed with nutrients.
Q: Do bean sprouts have calories? A: Yes, bean sprouts do have calories, but they are extremely low. A small serving contains very few calories and a host of vitamins and minerals. They are an excellent addition to salads and stir-fries for minimal caloric impact.
Q: What is the primary reason some beans are lower in calories than others? A: The main factors influencing calorie difference among beans are their composition, particularly the ratio of carbohydrates, protein, and water. Green beans, for example, have a high water content and lower starch density compared to mature, dried beans, which naturally results in fewer calories per serving.
