It may or may not be fraudulent, but please keep in mind that certain US states have ~ 40% obesity rates. It sounds obvious to the non-obese that eating like there is no tomorrow is not conducive to a good life; and simple measures, like eating less and moving more, can dramatically improve quality of life. But to the obese, it might not be so obvious for a variety of reasons (and yes, there are also genetic and environmental and mental health problems contributing to obesity, but also not caring much about one's own life).
