Is your microwave making you fat?

Weight Loss Dude recently asked the question Do Microwave Ovens Make You Fat? and I think he has a valid point. After all, what do we use microwaves for? Popcorn, frozen pizzas and other convenience foods that aren't good for us. But there's more to it than that -- there are several theories out there that using a microwave on your food destroys the nutrients in your food, and this could perhaps cause your body to store your microwaved food as fat.

I don't know how true this is but I think we all need to practice safe microwaving techniques; the microwave should never replace healthy home-cooking. Reheating healthy left-overs is fine, but make sure to avoid using the microwave for non-nutritious food.

What do you think?
