U-curve phenomenon

A dose-incidence mortality curve that describes the relationship between alcohol intake and the risk of coronary artery disease (CAD)-related death. The U-curve phenomenon also occurs in weight loss/gain, where those subjects with the most stable weight have the lowest mortality for all non-malignant causes and CAD. Mortality may increase in patients who undergo frequent weight cycling.
