Well, Trudie beat me to the punch, but I agree with her completely. In addition to melons being low in calories, they are also high in water content, which helps to fill you up and keep you hydrated..
I've read, and have even tried it on occasion that eating an apple about 30 min to an hour before each meal will keep you from SO hungry at meal time and you will eat considerably less calories at the meal. Drinking a glass of water helps in the same way, but isn't as satisfying.
I eat a lot of apples - sometimes 2-3/day and in addition to being low calorie and all the other good things Trudie mentioned, they help keep my digestion "issues" to a minimum.
Another favorite of mine is cherries. They have only 90 calories/cup and are very satisfying to munch on.
Remember - eating the whole fruit is always much better than just the juice....
Found this on a web site. Also, use the food diary to check out the calories, etc.
What are the best choices when it comes to fruits for weight loss? The healthiest options will be the lower calorie, low carb fruits, although even higher calorie fruits such as the banana are a far better alternative than most snacks found in a vending machine. One of the best fruit choices is the apple. Apples are not only low in calories and relatively low in carbs, they're also high in pectin, a natural ingredient similar to fiber, which helps to promote satiety. In fact, consumption of pectin has been shown in studies in animal studies to lower insulin levels and promote weight loss. An apple a day may be one of your best choices for keeping the fat away. Other good fruits for weight loss are blueberries, strawberries, blackberries, cantaloupe, and honeydew because of their low calorie content.
