- I don't think that issue will appear in the Med School lib for
- several days yet. In the meantime all I've seen are some press
- reports, and they leave something to be desired.
-
- There was mention of a 40% underreporting in the "control
- group". The nature of this "control group" is not clear, but it
- reminds me of papers I've seen indicating the obese underreport
- their intake about the same as others do.
-
- If the actual intake was 2080 kcal/d instead of 1200, that still
- would be within the range of 2765 +- 252 calories per day for a
- group of women with BMI of 18.96 +- 0.52 and 1425 +- 194
- calories for a group of women with BMI of 23.12 +- 0.96. But
- then it may be necessary to increase those other figures by 40
- per cent to make them comparable.
-
- The networks I heard rather dramatized this story. One of the
- wire service press reports included a number of comments from
- other researchers:
-
- In an editorial accompanying the study, Drs. Elliot Danforth
- Jr. and Ethan Sims of the University of Vermont in
- Burlington warned against misinterpretingthe results. The
- findings should not be taken to mean "that obesity is simply
- the result of gluttony and sloth and that obese people fool
- themselves and others about their eating and physicial
- activity," they said. The pair speculated that unusually low
- metabolic rates may still play a role in many cases of
- obesity, perhaps as a way of stabilizing energy consumption
- to prevent even more weight gain. "Diet resistance does not
- explain why obesity occurs, but it may be one reason that,
- despite their best efforts, some obese people regain weight
- they have fought hard to lose by dieting," they said.
-
- Maybe someone could fax me the NEJM article and editorial. (503-621-3735)
