ClinConnect Summary

This work will address the interaction of obesity and dietary fatty acids in regulating satiety and energy metabolism. The primary objective is to determine the effects of chronic intake of dietary fatty acids of varied saturation and chain length on satiety, thermogenesis and energy utilization in healthy individuals. The investigators hypothesize that unsaturated fatty acids will 1) increase satiety and 2) increase energy metabolism and that 3) the fatty acid binding protein polymorphisms are associated with reduced energy expenditure in response to dietary fat intake.
