Bananas, pineapples, watermelon, dates, avocado, and mangoes are some of the fruits that dieters should avoid. Eating such fruits, especially in large quantities, can lead to weight gain.

Mangoes are a good source of vitamin C and A. However, mangoes also have large amounts of sugar and calories. For a weight-loss plan to succeed, dieters should avoid the fruit.
