“Effect of a fat spread enriched with medium-chain triacylglycerols…on cardiometabolic risk factors in overweight patients with diabetes” (Siener, et.al. Nutrition and Metabolism. 2011)
Article’s table 2 shows waist circumference fell 2 cm in those consuming >7g/day of MCT oil versus those consuming <=7g/day who lost nothing. Body weight did not change so I suppose the high-MCT users lost fat and gained muscle. Uric acid increased about 5% in high-MCT group. Suppversity and superhumanradio.com have reported on health problems possibly associated with increase of lineoleic acid in our diet and MCT oil consumption in both groups was associated with at least 37% reduction in LA/(EPA+EPA+DHA) consumed. Fasting triglycerides curiously increased in both MCT groups. [all differences here were statistically significant].
Article also summarizes: Omega-3 fatty acids (n-3-PUFA) are anti-inflammatory, anti-thrombotic, and anti-arrhythmic, and EPA/DHA in particular lower triglycerides.
On MCT and ketone production:
“I would be lead to believe that the increase in ketones in the morning is due to low(er) insulin levels and high(er) cortisol levels increasing the break down of fat stores…. as we know, the incomplete breakdown of FFAs in the liver is what creates a ketone body.”
“The reason [Bulletproof Intermittent Fasting] is “ketogenic” is because of the medium chain triglycerides from MCT Oil and short chain fats of butter.”
“IFing causes an increase in GH and Test. so you will mobilize fat easily during the fast, especially around the hard to lose areas such as the belly. Ketosis will aid in fat burning, too, but not necessarily because of surges of GH/Test., but because you are mobilizing massive amounts of fatty acids and the low insulin promotes your body to utilize fat rather than put everything you eat into storage at the liver, muscle, or fat cell.”
