by Priyanka Sadhukhan , Nutritionist, CDE, Reviewer & Writer

Fruits and vegetables are always the best option to keep you healthy and fit. However, bananas have always been controversial – are they fattening, or do they aid weight loss?

It is claimed that eating banana and milk for a few days helps you shed some flab. Nutritionists also suggest that you eat at least one banana a day. But on the other hand, athletes eat bananas as a pre-workout meal to boost up energy and bulk up muscle mass.

This article explores the relationship between banana and weight to figure out if it is a weight loss or a weight gain fruit. Swipe up to find out more!

Nutrition Facts Of Bananas

Banana is loaded with nutrients. It is a cost-effective and quick source of energy. A medium-sized banana (~118 g) provides 27 g of carbohydrates, 3.1 g of fiber, and 105 calories of energy. It also provides 422 mg of potassium and 0.43 mg of vitamin B6 (1).

Half of the total carbohydrates in a ripe banana are sugars (14.4 g) that provide quick energy to athletes to improve performance (1).

Green banana contains resistant starch (RS) and loads of fiber (2). Upon fermentation in the gut, RS produces a short-chain fatty acid called butyrate. Butyrate improves your gut health and prevents constipation (3).

A study conducted at the Brigham Young University (USA) found that increased fiber intake aids weight loss and reduces excess calorie intake (4).

Banana is also high in potassium, which helps lower your BMI and weight (5).

But, the question remains – is banana a weight gain or a weight loss fruit. Let’s dig deeper!

Is Banana A Weight Gain Or Weight Loss Fruit? What Research Says

Banana is a versatile fruit that can be taken in limited portions to lose or maintain weight. Have it as a snack instead of a full meal.

  • Banana is a rich source of fibre that adds bulk to your meal and cuts down unnecessary calorie intake (6). Eating a medium-sized banana as a snack aids weight loss.
  • Banana is known for its high calorie content. However, a medium-sized banana is loaded with digestible carbs and sugars that are satisfying and better than other sugary processed snacks (1).
  • The resistant starch (RS) in both green and ripe banana spromotes fat oxidation, lowers fat storage in adipose cells and may promote weight loss (7), (8).
  • Banana is rich in vitamins and minerals (micronutrients). These micronutrients act as cofactors (non-protein chemical compounds that accelerate enzymatic activity to release energy) in glucose metabolism and energy expenditure. This helps in reducing the risk of obesity and diabetes (9).
  • Both ripe and unripe banana have a low glycemic index and a high satiety index (10), (11). A study conducted in Spain found that a low-GI, energy-restricted diet was more effective in aiding weight loss than a low-fat, high-GI diet (12).
  • Banana is high in calories and sugar. As it is a cost-effective energy source, it improves the exercise endurance of athletes (1). Therefore, eating bananas along with other healthy foods or protein supplements helps you gain weight.

Now that you know how bananas can help you lose as well as gain weight, let’s check out how you can consume them for both purposes.

How To Eat Bananas To Lose Weight

Banana has a high satiety index and is loaded with fiber. Eating banana as a snack or as a pre-workout meal helps supply the necessary nutrients needed to make you feel full and provide energy.

How To Eat Bananas To Gain Weight

Bananas are rich in calories, why is why eating bananas is considered to be an age-old method to gain weight. The best way to incorporate bananas in your regular diet for weight gain is to add it to smoothies or milkshakes.

Besides its weight gain and weight loss potential, banana provides a host of other health benefits. Check out below.

Other Potential Benefits Of Banana

  • Banana contains pectin and resistant starch, which delay gastric emptying, improve glucose tolerance, and help in the moderate regulation of glucose (13), (14). Nevertheless, always consult a nutritionist to plan out a balance diet with banana intake for diabetes.
  • The resistant starch in raw banana escapes digestion in the small intestine and gets fermented to produce short-chain fatty acids. This stimulates colonic blood flow and improves gut health (15).
  • Banana is a rich source of potassium (1). Potassium protects the heart and lowers the risk of stroke, especially in older women (16).
  • The bioactive compounds in banana improve your overall health. They reduce the incidence of degenerative diseases and oxidative stress (17).

Now that you know all the ways that banana improves your health, let’s check out how you can make a delicious smoothie with it!
