Excess free fatty acid release (rate of appearance) is seen in overnight postabsorptive, upper body obese women and, if present postprandially, could contribute to glucose intolerance. These studies examine the antilipolytic effect of a mixed meal in upper body obese, lower body obese, and nonobese women and the contribution of meal triglyceride fatty acids to circulating free fatty acids. Eight upper body obese, 8 lower body obese, and 8 nonobese age-matched, premenopausal women were studied. Systemic oleate Ra ([3H]oleate) was measured before and after an evening meal that contained triolein labeled with [14C]triolein as the only source of fat. Premeal oleate Ra was greater in both upper body obese and lower body obese women than nonobese women. The nadir of total oleate Ra occurred 90–240 min postprandially and was less (P < 0.01) in nonobese and lower body obese women (63 ± 10 and 87 ± 17 μmol/min) than in upper body obese women (140 ± 21 μmol/min). Meal oleate Ra contributed substantially to total oleate Ra. The nadir for endogenous oleate Ra in nonobese and lower body obese women was less (P < 0.01) than that observed in upper body obese women. We conclude that the antilipolytic effect of a mixed meal is reduced in upper body obese women and that meal triglyceride fatty acids contribute significantly to postprandial free fatty acid flux.
