 Overweightobesity is the second leading cause of death in the US, and is growing in prevalence at an alarming rate. Control of overweightobesity is increasingly recognized as a high national priority because of its contribution to cardiovascular CVD risk factors and ultimately to CVD itself.

Of the factors that are associated with sustained weight loss, one of the most important is continued intervention with frequent contacts.
