Obesity is a rapidly growing epidemic that now affects approximately 30% of the adult population in the United States. The prevalence of obesity in the geriatric population makes it one of the fastest growing groups due to aging baby boomers. Because of the limited number of available treatments for obese adults, they often turn to supplements and alternative medicine sources to help them lose weight. One such group of supplements contains plant metabolites flavonoids, which includes catechins from tea, quercetin from fruits and vegetables, and isoflavones from soy products. Some flavonoids such as catechins and soy isoflavones can modestly reduce weight. This review examined the clinical evidence for catechins, quercetin, and soy isoflavones for the treatment of obesity and explored the mechanisms of action as related to obesity. Furthermore, flavonoids were evaluated for the treatment of obesity in geriatric populations as well as for safety concerns.
