Abstract

OBJECTIVE: Differences in the metabolic response to overfeeding and starvation may confer susceptibility or resistance to obesity in humans. To further examine this hypothesis, we assessed the changes in 24 h energy metabolism in response to short-term overfeeding and fasting in Caucasians (C) and Pima Indians (I), a population with a very high propensity for obesity. METHODS: We measured the changes in 24 h energy expenditure (24 -EE) and 24 h respiratory quotient (24-RQ) in response to 48 h of mixed diet overfeeding (100 above energy requirements) and fasting in a whole body respiratory chamber in 14 male subjects (7 C/7 I, age 30+/-6 y, mean+/-s.d.). Results were compared to a 24 h measurement under eucaloric conditions. RESULTS: Mean 24-EE increased in response to overfeeding and decreased in response to fasting (all changes P
