I used to eat a lot more fruit than I do now (though I do still eat it just less), 6 apples a day on average, a tub of strawberries, a bunch of bananas and a punnet of grapes, weren't unusual for me in one day. I didn't get fat. However, I was already fat anway. I actually lost weight until I got down to 11.4 stone, which was actually underweight for me (although I did do regular 10 mile walks). And I still had the stomach (though it wasn't as big, it was still big)! And still do, despite trying to get rid of it for years (and being a healthy weight)!
