As a practicing physician, Jason Fung tends to heavily rely upon scientific studies as a means to explain his various viewpoints on obesity, as well as to debunk commonly held myths on obesity and assumptions that can become problematic. A great deal of the studies that he uses are from the past 10 years, but a few date several decades back, mostly in order to demonstrate how nutrition and obesity research has progressed and evolved over long periods of time. Fung makes a strong effort to put his focus upon causal factors rather than association studies, as associations aren't always as concrete or as helpful as causation can be. In conjunction with scientific research, Fung takes time to describe various biological processes that demonstrate how different bodily systems work in concert to either promote weight gain or weight loss.
