Samuel Klein elegantly points out that environmental, cultural, and lifestyle factors are the major driving forces behind the continued fattening of Americans (1). Another lifestyle factor that might contribute to the escalating overweight epidemic in the USA is the reduced incidence of smoking, and the increased rates of smoking cessation.
While its health benefits are unquestionable, smoking cessation has been clearly shown to be associated with weight gain (2,3). Indeed, nicotine itself is known to reduce food intake, and nicotinic agonists have been proposed as potential weight control agents (4). Clearly, more efforts are needed to educate those who quit smoking to increase their physical activity as the best remedy against the associated weight gain (5).
