Bananas are good for weight loss because they are full of nutrients but not high in calories. Additionally, the calories found in bananas are mostly free of fat. Because bananas provide the energy that an active lifestyle requires as well as nutrition without fat, they are great snacks when dieting.
A 7- to 8-inch yellow banana contains 105 calories but only 1 gram of unsaturated fat and 1 gram of saturated fat. Saturated fat and sugar are two of the main contributors to weight gain and obesity. In addition to this low fat content, a banana contains 27 grams of carbohydrates to provide the body with energy.
Ideally, bananas should be consumed when ripe and plump but without brown spots on their skins. Brown spots indicate that the starch in bananas has turned into sugar, which is bad for weight loss.
