Okay, this is probably a silly question, but...

Is watermelon considered a true melon?

Neanderthin advocates melons and berries as being the best in the fruit
group...

But watermelon is also loaded with sugar, right?

What do you guys think?

And, what do you think are the fruits least likely to cause weight gain (in
order of best fruit to worst)?

Thanks for the help!  Janet
