"As long as energy expenditure exceeds that of intake, a decrease in body weight must occur. That can be stated with absolute certainty." - Betsy B. Dokken, PhD, NP, CDE "The Physiology of Body Weight Regulation: Are We Too Efficient for Our Own Good?" -Diabetes Spectrum, July 2007

It can be tough going with the medical vocabulary but it is really worth it, I kind of feel like I'm having an aha moment - a revelation that calories aren't the end all be all, that instead it is fuel in, energy spent that is more crucial.

Thanks for sharing. This was really interesting. I am a medical writer, and I enjoy reading about my health issues (Obesity) from a medical research point of view.
