Weight watchers has listed it as one of their zero point foods, so therefore you can eat a banana or two if you want to. I usually eat one during the day when I want something sweet and I have grapes for a snack at night. I guarantee you I didn't get overweight from eating too many bananas. However, I do try to have a small one and I usually eat just one a day, maybe two, if I'm feeling a little hungry that day.
