Subject: Weight loss is harmful

I attended this event today and Professor Kim Overvad presented graphs showing 
that weight loss increased all-cause mortality. A stable weight was most 


I discussed this with him after the event. He said that the rodent studies 
probably had given misleading results, because the animals were "too well fed" 
in the lab and the caloric restriction corrected for that. 

It appears that the socially accepted ideal weight is too low for optimal 
health, especially for women.

This brief review summarizes some of the investigations in this area:

Effects of Intended Weight Loss on Morbidity and Mortality: Possible 
Explanations of Controversial Results. (2006)

Tina Berentzen, MSc, and Thorkild I.A. Sorensen, DrMedSci. Nutrition Review, 
Vol. 64, No. 11

Long-term, population-based, observational studies have shown that intended 
weight loss does not always reduce the mortality associated with obesity. The 
effects of weight loss on mortality may be a balance between the effects of the 
loss of harmful abdominal and ectopic fat mass and the loss of beneficial 
peripheral subcutaneous fat mass and lean body mass.
