Recent population studies indicate that energy intake is decreasing while the prevalence of obesity continues to rise (Bray and Popkin, 1998). This may be due to the consumption of a high fat diet by western cultures, an increasing sedentary hfestyle or an interplay between both factors. Previous work by Pierce (1998), describing a chance observation that rats that had eaten a high fat diet exercised less than controls, suggests that eating fat per se may diminish physical activity. Aims The aim of the present study was to determine whether: a) intake of dietary fat; or b) a higher than normal body weight; or c) a combination of the two (a and b), affects voluntary physical activity in rats.
