Yes, banana is good for weight loss in a measured portion. One medium robusta banana (100 g) gives 105 kcal, 23.6 g of carbohydrate and 1.9 g of fibre. It is one of the most convenient pre-workout snacks there is; what matters is one banana, not three.

The verdict on banana

Whole fruit

One counted fruit in place of a sweet or a packet snack.

  • 1.2 g of protein for every 100 kcal.
  • One serving gives 1.2 g of the roughly 58 g of protein a day ICMR-NIN's RDA sets for a 70 kg adult.
  • 1.9 g of fibre in a serving.

How banana fits a plan that loses fat and keeps muscle

IFCT 2017 puts the ripe robusta banana at 105 kcal per 100 g, higher than most fruit because it carries more starch and sugar and less water. That is not a reason to avoid it. It is a reason to count it as a snack with a number, rather than a free fruit.

A banana before a walk or a strength session is easy fuel that keeps you training, and training is what keeps muscle while fat comes off. Pair it with protein when it is a snack on its own, so it holds you until the next meal instead of sending you looking for more.

Banana in an Indian kitchen

Small elaichi bananas and the larger robusta both count as one fruit, but a big robusta can be close to two small ones, so match the size to your serving. A banana before a workout gives quick, easy fuel. Sliced into a bowl of curd or oats, it sweetens breakfast without sugar. Very ripe bananas freeze well for a smoothie with milk and a spoon of peanut butter, in a measured portion. Raw green banana is cooked as a vegetable in Kerala and Bengal.

Pair it, or swap it

Banana with a katori of curd, a glass of milk or a small handful of peanuts turns a quick sugar into a balanced snack. Slice half a banana into oats or dalia for sweetness without added sugar.

Worth knowing

Banana shakes with sugar, ice cream or honey, and banana chips fried in oil, are different foods from the fruit. A larger banana can be 150 g peeled, half again the numbers above.

Banana: questions people ask

How many calories are in one banana?

One medium robusta banana, about 100 g peeled, gives 105 kcal per IFCT 2017, with 23.6 g of carbohydrate and 1.9 g of fibre.

Is banana good for weight loss?

Yes, as one measured fruit a day, ideally around activity or with protein. It is higher in calories than most fruit, so count it.

Can I eat banana at night when trying to lose weight?

Yes, if it fits the day's total. Timing matters far less than the total and the company it keeps: banana with curd or milk is more filling than banana alone.
