During the 1990s, something that had already been happening, suddenly became very much more noticeable. People were becoming fat.
Many people watched the TV or player computer games where before they would have gone out and played field games. they became 'couch potatoes'.
More people also ate processed foods, which are high in fat. As a result, people started to get fatter and fatter and the clothes sizes sold in shops got bigger and bigger.
