A group of inventors, who include the creator of the Segway, has come up with a gadget that lets people eat pretty much what they want and forget about the calories.

Sound too good to be true?

Called the AspireAssist device, it works by sucking the food right out of the stomach so that only about a third of the calories are absorbed by the body.

Patients wait 20 minutes after eating, then empty 30 percent of their stomach contents into the toilet through a tube -- a small, handheld device connects to a skin-port discretely embedded on the outside of the abdomen.

Calories not digested are calories not absorbed, which, say the inventors, leads to weight loss.

In a one-year trial of 24 obese patients, patients on average lost 49 percent of excess weight, the equivalent of about 45 pounds.
