At the Institute of Food Research in Norwich, England, foods are being developed that would help a person lose weight by slowing down the digestive system and triggering a signal to the brain to suppress appetite. It would control appetite by tricking the brain into thinking that you have eaten too much when you actually haven’t. The products could possibly be sold on the market in a few years.

Scientists at the University of Newcastle are testing a seaweed extract called alginate that would reduce fat absorption by cutting the level of glucose that is digested by the body before it is broken down in the large intestine. In taste testings done with several dozen people, it is found that most people felt that the foods enhanced by alginate tasted as good or even better.

Scientists in North America and Europe are developing products to control appetite, such as chemical injections and implantable devices that would interfere with the digestive system. It is not certain if appetite controlling foods could cure all cases of obesity.
