Effects of snacks on energy intake: an evolutionary perspective

Cees de Graaf. Appetite. 2006 Jul.

Abstract

The question addressed in this paper is whether the consumption of snacks contributes to higher energy intake and body weight in humans. Currently available snacks have a higher energy density than most of the foods that were available in Paleolithic diets. Humans have a weak defense against overeating, which is a functional trait from an evolutionary perspective. Various studies found that people do not compensate their energy intake after the consumption of snacks. This is particularly true for energy-containing drinks, which provide calories in liquid form. It is concluded that snack consumption may contribute to a positive energy balance.
