Medium-chain triglycerides (MCTs) have been popular in the bodybuilding world for several years as a means to increase metabolism and accelerate fat oxidation. The structures of MCTs are unique in that they are able to bypass other means of metabolism when compared to other forms of fat, making them an excellent consideration to aid in a healthy diet to improve body composition and one's physique.
A recent study was published in the European Journal of Clinical Nutrition and compared a single feeding of MCTs to other forms of fat for their ability to impact how much food someone consumes in addition to their appetite (St-Onge, Mayrsohn et al. 2014). During an identical breakfast meal either 20 grams of MCTs or another form of fat was provided and then lunch was served three hours later where participants could eat as much food as they wanted. A follow-up study used the exact same approach but provided another dose of either form of fat 3 hours after breakfast and then provided lunch one hour after the second dose of either fat. When MCTs were provided, the number of calories consumed at lunch was significantly reduced and participants rated their appetite levels to be better when MCTs were consumed.
