Pineapple

A friend of mine is going away for the weekend. He stopped by very briefly to borrow a small suitcase. When I picked it out I realized it was very dusty which reminds me of two things. First, I don't travel much these days, and second, I need to have a chat with putz-Peter :) Anyway, while here he stuck me a box of sliced pineapple (fresh) telling me that this is a great fat-burner. Didn't have a chance to ask why. Why is it that pineapple burns fat? Can that really be true? And more importantly, is icecream a fat-burner too :) ??
