“In 1995, newspapers in the US reported the death of the fattest man in the world. He had come to weigth 465 kilograms… and had to be transported by fork lift truck.
Obviously he was an example of the obesity problem, yet it would have required a weigth gain of only 37 grams per day to take him from a normal 70kg at the age of sixteen up to eh grotesque proportions of his death at just 45 years of age. This is the equivilent of eating an extra 250 calories per day – less than one normal chocolate bar.”
