In today's (21 May) The New York Times, Jane Brody is writing about multiple factors contributing to the obesity epidemic. In it, she makes this statement that caught my attention:
"If a person's weight drops to 150 pounds from 250, significantly fewer calories must be consumed daily to stay at that weight than would be necessary if the person had never been overweight."
Brody offers no references and I am unable to find support for it elsewhere. I don't believe it myself, but if there is such an effect, there must be more to it, taking into account how the person came to be overweight. What do you think?
