According to research published in the American Psychological Associations' Psychological bulletin, eating a wide variety of snacks and buffet food may be the cause of weight gain. Scientists from the University of Buffalo believe that the modern diet encourages overeating by offering a diverse range of interesting foods, decreasing the effects of satiation on the eater, the feeling of being satisfied. On the other hand, sticking to a more boring diet with repetitive meals and foodstuffs could dull the palate so that people eat less.
