MCT stands for “medium chain triglycerides”, a type of fatty acid that the body can digest very easily (unlike longer-chained fatty acids). It goes straight to the liver, where it is either oxidized or turned into ketones, which our bodies use for energy. As a result, people often experience a burst of energy immediately after consuming MCT oil.
A Natural Source of Fat
MCT oil is a completely saturated fat. It’s the same fat that is found in coconut oil, so there’s no real need to supplement with MCT oil unless you’re trying for ketosis. That said, if you are trying for ketosis, then MCT oil can absolutely be a Paleo-approved way to get some extra fat in your diet.
Even Mark Sisson has dabbled in adding MCT oil to his diet.
