Guest guest Posted April 6, 2006 Report Share Posted April 6, 2006 Hi, this looks like the same " Comprehensive Assessment of the Long Term Effects of Reducing Intake of Energy " (CALERIE) study posted earlier from Louisiana State that was just published in JAMA. (Diane Walter's post #22883). Funny how each write-up portrays it a little differently.
