What's next? Gluing your mouth shut so you can only eat what fits through a straw? The latest fad diet is the "feeding tube diet," which involves a doctor putting a feeding tube down your nose and carrying around a bag filled with liquid proteins and fats.

This seems like an extreme way to lose a few pounds. My question is, can you eat other things while the tube is down your throat? Would it stop you from downing a Twinkie or some ice cream?

Hopefully this extreme diet will fade away into the woodwork. Exercise, not malnutrition, should be the first focus of any diet.
