April 8/Ithaca, N.Y./The Cornell Daily Sun -- Prof. David Levitsky, in the department of psychology and nutritional sciences at Cornell University, says the availability of a greater variety of foods is linked to eating more and thus, weight gain.
One of the studies that Levitsky conducted showed that if a subject eats small portions, he will not compensate by eating more later, resulting in weight loss. Another study that Levitsky recently published showed that the greater variety in foods that are available, the more the person will eat.
