Dr. Dympna Gallagher shows that REE reduces more in weight loss than  can be explained.

Fat Free Mass(FFM) of 60 to 50 should just move REE down same(red) line but it moves to lower lines(Green & Blue).  "Which is something that is well noted in EE studies,  that when people loss weight the REE decreases to a greater extent than can be explained by the decrease in FFM. "


"Resting Energy Expenditure (REE) is largely mediated by your body composition."

Graph in photo below shows REE as a function of FFM (fat free mass) before surgery (red line), one year later (green line) two years later (blue line)
