Background. Upper body obesity (UBO) results in insulin resistance with regards to free fatty acid (FFA) release; how this differs by fat depot and sex between UBO and lean adults is unknown. We tested the hypothesis that insulin suppression of FFA release from the splanchnic bed, leg fat and upper body non-splanchnic (UBNS) adipose tissue would be impaired in UBO.
