Overfeeding of Polyunsaturated Versus Saturated Fatty Acids Reduces Ectopic Fat
Just curious as to why this might be?
"The main finding of the new report is that the size and distribution of fat depots varied significantly according to the type of fat that was consumed. The PUFA group gained equal amounts of fat and lean tissue, but those eating the SFA diet gained four times as much fat as lean tissue. In particular, the SFA diet resulted in a significant increase in liver and visceral fat relative to the PUFA diet. Further, the increase in liver fat was positively correlated with increases in SFA as measured by plasma palmitic acid. In contrast, the PUFA diet increased lean tissue significantly more than the SFA diet. But the nature of this “lean tissue” is unclear. Because participants did not change their activity levels during the study, this lean tissue is probably not “active” muscle, although it might represent protein in other tissues."
