MCT oil
For brain fuel and ketogenic diets
The experts we follow agree on this.
MCT oil is a popular, easy fuel for the brain and can boost ketone production.
Who is behind it
Voices including a molecular biology PhD, a licensed acupuncturist and clinician-educator and a former research biochemist.
How strong the research is
Backed by some published research, and by what the experts see in practice.
In their words
“MCT oil, which is 100% saturated fat. And every Not everybody, but people of all walks of life and diet, keto or non-keto, all really like MCT oil.”

MCT oil is metabolized differently and acts like a ketone in the body
MCT oil is popular in ketogenic diets because it allows higher ketone levels while eating a more standard looking plate of food and promotes endogenous ketone production.
This combination promotes serotonin and melatonin production, provides steady amino acid supply overnight, and supports slow wave sleep and recovery.
MCT oil supports energy and fasting benefits while reducing cravings.
With care
Some of the minds attach conditions. These are worth reading before you begin.
Adding MCT oil to time restricted feeding is one of many ways to tackle intermittent ketosis beyond just ketogenic diet.
