The best fruits to eat for fat loss are the ones that will allow you to eat fewer calories than you burn. For example, although a banana is higher in sugar and calories than a handful of grapes, if eating a banana will make it less likely that you will raid the vending machine in search of a Snicker’s bar, it is a better choice. Lifestyle issues aside, my pick for best fat-burning food is grapefruit. Grapefruit’s high water content helps increase feelings of fullness while providing very few calories. In fact, it takes more energy to digest grapefruit than it contains in calories. While this does not mean someone can eat grapefruit along with anything else he or she pleases and lose weight, adding it to a well-balanced nutrition plan will certainly aid in fat loss.
