In a feeding study with metabolic syndrome patients, increasing carbohydrate intake while decreasing saturated fatty acid intake resulted in higher serum saturated fatty acid levels when dietary saturated fat intake was lower and carbohydrate intake was higher.

“what we can see here is that what we have when we take a look at these two arms is taking a look on the right to the change in serum saturated fatty acids we can see in the carb restricted diet you know significant decrease versus the low-fat diet so again in the much higher saturated fatty acid arm we see a significant decrease down okay whereas we do see a drop in the saturated fatty low saturated fatty acid intake group but not nearly as much as we see with the carbohydrate restricted group”

“what we see is that it's actually the saturated fatty acid content is actually higher with the lower saturated fat intake and we're going to come back and talk to about the science behind that but i think it's really important for people to see this clinically and then maybe when we get into a little bit more of the nitty-gritty um it can make more sense okay i mean it's it's actually statistically insignificant in terms of c16 right which is the dominant saturated fatty acid so so palmitic acid it trended towards an increase as saturated fat dietary saturated fat went down um and such and carbohydrate went up but it didn't reach significance and um the only one that actually did significantly increase with c14 right yeah actually um c 16 1 as well and that one is we're going to oh yes but but yeah yeah no but as a saturated fat it was really just as a saturated yeah so but the point of this is we didn't have these really high levels of serum saturated fatty acids when we were consuming when these participants were consuming this very high saturated fat diet i mean essentially and this is important it stays the same if anything there's a trend okay to higher serum saturated fat in the low fat arm okay but certainly we do not see a rise in the high intake of saturated fat that's super important and again it goes against what i was saying earlier on you know you are what you eat well okay if that's true then when i consume a very high level of saturated fatty acids why am i not seeing that again in the blood in the serum why are we not seeing that and and what's nice in this study is you've exhaustively looked at where the fatty acids are so obviously the most efficient place we store fatty acids is in the triglyceride but you also store it within the cholesterol ester and it's obviously in the phospholipid as well but regardless of where you look you see no association between dietary saturated fat and fatty acid composition with respect to saturated fat that's right that's right”
