A long-range health study in Framingham Massachusetts, which began in 1948 and continues to this day involves checking the survivals among the same 5,200 men and women every two years and carefully determining the causes of any deaths occurring in the group. A rather 5 surprising conclusion that emerged in 1980 was that the lightest men had the shortest life expectancy. While the only others for whom weight seemed to have a significant negative effect on life expectancy were those who weighed more than 25% above the national average. Much the same was true of women, with those in the lightest and heaviest 10 groups dying earliest.

These results certainly cast considerable doubts on the validity of the "Ideal Weights" tables in use since the forties which recommend weight to height ratios well below the national average. Indeed, 15 they suggest that if any such ideal exists, it is slightly above the average, whatever fashion may dictate.
