ABSTRACT
Anorexia nervosa (AN) inevitably begins with dieting. Yet, it is unknown whether anyone who will ultimately suffer from anorexia is already ill upon "going on a diet", or whether disease begins during, and is perhaps triggered by, dieting. The objective of the following study was to precipitate anorexia by imposing diet restriction on animals, as a model for generating AN in humans. Three hundred young female Sabra mice were diet restricted to 40% of daily nutrient requirements for 12 days, lost 17% of body weight and were then re-fed ad-lib. All mice regained appetite and weight. Our conclusions are that diet restriction does not precipitate anorexia in mice. Our findings do not support a role for diet restriction per se in triggering AN.
