in my opinion. no but too much of any fruit would likely cause an increase in fat tissue. if you are among those that have been sadly blessed with more fat tissue around your belly then it could happen. i do not believe there is any definitive scientific evidence that bananas alone are the culprit for belly fat. the distribution of human adipose tissue (fat) is much more complicated than just nutritional. genetics plays a significant role.
i read conflicting views on the internet. do bananas increase belly fat?
