Fruit, generally considered a beneficial food, provides nutrients and fiber to your diet. However, consuming certain fruits that contain high levels of sugar when you are striving for weight loss can thwart your efforts. When high levels of sugar hit the bloodstream, its potential energy is intercepted by insulin that stores the sugar as glycogen. When the sugar is stored, your body thinks you need to eat more and you feel hungry. If this cycle repeats, over time the stored sugar transforms into fat, and you gain weight. Eating low-sugar foods instead may help you eat less often and lose weight, according to the website Glycemic Index.

If you crave a sweet fruit, try eating a peach instead. Peaches have a score of only 42 on the glycemic scale, and when ripe, their sweet and refreshing flavor may be equally as satisfying.
