Some related data and researches has been done by The NPD Group, a leading global information company.

Based on the data released by The NPD Group in 2013, “about 20 percent of adults report they are on a diet, down from a peak of 31 percent in 1991 according to NPD’s National Eating Trends® food and beverage market research. In 1992, 34 percent of women told NPD they were on a diet; and in 2012, 23 percent of women reported being on a diet.”

Also according to the demographic information of U.S. Census Bureau, in 2012, American total population was 308,827,000, with 151,175,000 male and 157,653,000 female.

Combined these data, it can be calculated that in 2012, there were 23% of women (36,260,190) in America reported that they were on a diet, while about 16.7% of men (25,505,210) reported.

Therefore, based on the data of The NPD Group and calculation, the claim which quoted the data of 1992 is not a fact.
