Want to lose weight? Try eating. That's one of the strategies being developed by scientists experimenting with foods that trick the body into feeling full.

At the Institute of Food Research in Norwich, England, food expert Peter Wilde and colleagues are developing foods that slow down the digestive system, which then triggers a signal to the brain that suppresses appetite.

"That fools you into thinking you've eaten far too much when you really haven't," said Wilde. From his studies on fat digestion, he said it should be possible to make foods, from bread to yogurt, that make it easier to diet.
