Are Bananas Good For Weight Loss: Don’t Let Their Carb Content Put Your Off

are bananas good for weight loss

Bananas are a common and affordable fruit. Nutritious and healthy, they are generally considered a great snack alternative to various chocolate bars. You can cook anything with bananas from salads to healthy chips. And yet, not so long ago, opinions began to spread about bananas being inappropriate for your weight loss goals. The reason is that bananas are high in sugar, therefore high in calories, which should make them inappropriate for a weight loss diet. Let’s figure this out – are bananas good for weight loss? In this article, you will learn a lot about bananas and how to consume them if you are aiming to shed your excess pounds.


A Short History Of Bananas

Everyone knows what a banana is – despite being a tropical fruit, it is so widespread around the globe that you can buy it in every shop – from big malls to small mini markets. How did that happen? How did the banana manage to become so popular in the South and the North, in the West, and the East?

It is thought that bananas have been first domesticated in Southeast Asia. Bananas are mentioned in early Greek, Latin, and Arab texts, Alexander the Great saw bananas on his expedition to India (3). After the discovery of the Americas, bananas were taken from the Canary Islands to the New World, where they were first grown in Hispaniola and after that spread to other islands and then to mainland areas. Cultivation steadily increased until bananas became a staple food in many regions, and in the 19th century, they began to appear in markets in the U.S. Currently, Cavendish bananas are the most common variety imported by nontropical countries. This is the yellow, sweet variety you can see in every shop in your city.

The fact is, there are hundreds of banana varieties, fuzzy ones, striped ones and those tasting like strawberries. But for most people worldwide, there is only one type of banana – the Cavendish one. This would certainly be amazing news for Duke William George Spencer Cavendish, who propagated this plant in 1834 and gave it his name (15). 

Nowadays, the US consumes 3 million tons of bananas each year, and they’re the single most-sold item in Walmart. Globally, bananas are considered the fourth most valuable food crop, behind only wheat, rice, and milk.

First of all, bananas are filled with nutrients. Let’s consider their nutritional value. 

One medium banana is about 105 calories, 90% of which come from carbs – sucrose, glucose and fructose. Aside from that, one banana contains (5): 

  • Potassium: 12% of the RDI.
  • Vitamin B6: 20% of the RDI.
  • Vitamin C: 17% of the RDI.
  • Magnesium: 8% of the RDI.
  • Copper: 5% of the RDI.
  • Manganese: 15% of the RDI.
  • Fiber: 3.1 grams.

Also, bananas contain beneficial antioxidants like phenols, flavonoids and flavanols (1). On the other hand, a banana, just like most other fruits, is low in fat and protein. Let’s look through all of those elements in detail.

The first question that arises is about sugar. Most of the calories of the banana come from carbs, precisely, natural sugars. Does that mean a banana’s sugar content is incompatible with a healthy diet?

The short answer is no. First of all, carbs are a necessary component of a healthy diet. Eliminating all carbs from your diet is not practical and can even be harmful. They are a primary source of energy in your body. Consuming too many carbs can indeed lead to weight gain, but such is not the case with bananas. The difference is the distinction between “good” and “bad” carbs. The former, also called simple carbohydrates, can cause blood sugar to spike and are generally unhealthy. They are found in sugary drinks, white bread, cakes, cookies – in short, everywhere where there are sugars artificially added through the process of production. By contrast, “good” carbs are more complex and break down slowly, and are better for your health. Vegetables, legumes, whole grains, and fruits – like bananas – are sources of good carbs (8).

If that is not enough proof, let’s look at the banana’s glycemic index. Glycemic index measures how much certain food raises blood sugar levels. Excess consumption of foods with a high glycemic index has been linked to weight gain, an increased risk of obesity, heart disease, and stroke (6). However, the GI score of bananas is rather low, from 42 to 62, which means they have a low to medium glycemic index, depending on ripeness. This means bananas are not a high-glycemic food, and won’t cause blood sugar to spike and related consequences. Carbs in a banana release more slowly and which means more stable blood sugar levels.

Banana health benefits are further increased by their high fiber content. One banana provides 3 grams of fiber, which is about 12% of your daily recommended intake. 

Consumption of fiber has been linked to lower body weight, stabilization of blood sugar levels, reduced risks of heart disease and other health benefits (6). It is very good for your digestive health, and it makes you feel satisfied longer, resulting in lowering your calorie intake. A high-fiber and relatively low-calorie snack like a banana can delay hunger cravings and prevent you from consuming unnecessary extra calories. However, among other fruits, bananas are not the most filling, with apples and oranges being the leaders.

Potassium helps your body regulate fluid, send nerve signals, and regulate muscle contractions. A potassium-rich diet and a high fluid intake help maintain a good fluid balance. Aside from that, eating enough potassium helps balance the level of sodium in your body, lowering blood pressure. It also helps prevent incidences of heart disease and stroke (14). 

Vitamin B6

Vitamin B6 plays an important role in neurotransmitter production, which can affect mood regulation (2). It also may play a role in reducing Alzheimer’s risks and promoting healthy brain function (11). Since taking it can improve your mood if you were deficient in it, Vitamin B6 has also been used to treat certain emotional symptoms of premenstrual syndrome.

Vitamin C

Vitamin C is well-known for its positive effects on immunity, but it has a host of other benefits. In fact, the benefits of vitamin C may include protection against cardiovascular disease, prenatal health problems, eye disease, and even skin wrinkling (13).


Magnesium is a mineral found in the earth, sea, plants, and humans. It is indispensable for multiple functions in your body. Magnesium helps convert food into energy, helps create proteins, maintains and repairs DNA and RNA, helps contract and relax your muscles, and supports nervous system regulation. More practically, magnesium boosts your exercise performance and reduces symptoms of depression in adults with type 2 diabetes and a magnesium deficiency (at the level of an antidepressant drug!) (10, 7). While this is such an important mineral, about half of the people in the US and Europe get less than they need per day. While bananas alone can’t provide you with enough magnesium, just two bananas can give you 16% of your RDI, but combined with other products high in magnesium (like quinoa) can help you feel the benefits of this mineral.

Manganese is vital for bone health, including bone development and maintenance (12). It is a part of SOD, a very important antioxidant that protects your cells from various diseases. Plus, manganese helps reduce inflammation and plays a role in blood sugar regulation. 

Bananas Improve Your Exercise Performance

So, you can clearly see that a hundred calories in a banana are filled with important vitamins and minerals. As mentioned before, bananas contain important elements that can boost your exercise performance. In fact, a banana can be just as effective as a carbohydrate drink for endurance training (4). Plus, it increases your levels of dopamine, a chemical involved in the generation of feelings of motivation and reward. So, if you were looking for a top-level pre-workout snack, a simple banana may be an unexpected candidate. Indeed, since bananas boost your exercise performance, they are an amazing addition if you’re combining your diet with regular exercise. 

Why Are Bananas Good For Weight Loss?

As you can see, bananas can be a nutritious part of any healthy dietary approach. It is true that bananas provide most of their calories from sugar, but those sugars are “good”, natural sugars that do not cause blood sugar to spike as much as added sugars. Bananas have a low to medium glycemic index, making them a healthy carbohydrate source. Plus, bananas are filled with dietary fiber, which is important for digestion and makes you feel satisfied longer. Aside from that, bananas contain a host of vitamins and minerals indispensable for the normal functioning of your body.

Are Green Bananas Good For Weight Loss?

The benefits of ripe, yellow bananas for weight loss are well known, but green bananas may be even better. Unripe or green bananas have a higher resistant starch content than ripe bananas.Resistant starch is a type of indigestible carbohydrate that acts like fiber.  It’s found in starchy foods like rice, potatoes, and beans. When resistant starch reaches the large intestine, it’s fermented by gut bacteria. This process produces short-chain fatty acids, which have been linked to a number of health benefits, including weight loss.

Green bananas are also a good source of dietary fiber. Fiber promotes weight loss by helping you feel full and satisfied after eating, so you’re less likely to overeat. Fiber is also beneficial for gut health, which is important for overall health and weight loss.

As far as net carbs go, green bananas are lower in carbs than ripe bananas. Net carbs are the total carbohydrates in a food minus the fiber content. 1 green banana has about 10.9g net carbs, while a ripe, yellow banana has about 15g net carbs.

How should you eat green bananas for weight loss? Simply boiling or steaming them is a great way to enjoy their benefits. You can also add them to smoothies or make green banana flour to use in baking recipes. Just keep in mind that the longer you cook green bananas, the more resistant starch they lose.

Green banana tea is another option. To make green banana tea, cut a green banana into 2-3 pieces and add it to boiling water. Let the tea steep for 10 minutes, then remove the banana and enjoy.

Final Thought

To sum up, bananas would certainly fit any balanced weight loss diet. The only caution with bananas should be your calorie limit. As with any other healthy food, if you exceed your calorie limit, in other words,  you consume more than you burn, you won’t get rid of extra fat. So, eat bananas, track your calories wisely, keep your diet balanced (look through Keto, Vegetarian, or Mediterranean diets for examples), and drink plenty of fluids to make your body as beautiful as ever.
