Fruits that are heavily alkaline include watermelon, cantaloupe, mangoes, pears, grapes and passion fruit.

Watermelon is a low-calorie food, containing only 46 calories per cup. According to the Mayo Clinic, it takes 3,500 calories to make a pound of body fat, so watermelon is not likely to contribute to weight gain. Because a cup of watermelon contains less than a gram of fat, it is also appropriate for a low-fat diet. Watermelon also contains 139 grams of water per cup along with a small amount of fiber, so it can help fill you up and make you less likely to eat other, higher-calorie foods included in the same meal.
