Letter: Fighting flab?

Sir: Your report on the "disease" of obesity (13 March) describes the Body Mass Index (weight in kilos divided by height in metres squared) and says a person with an index over 25 is considered overweight, and over 30 obese.

For the Bruno/Tyson fight on Saturday, Bruno weighed in at 111 kilos with a height of 1.91 metres - an index of 30.43. Tyson, too, has an index above 30. Are these superb athletes obese? Clearly other factors are important in making medical judgements about body weight.
