Dietary medium chain triglycerides (MCTs) are a class of triglycerides in which two-to-three of the fatty acid chains attached to a glycerol backbone are medium in length. Medium-chain fatty acids (MCFAs) are fatty acids comprised of 6–12 carbons in chain. The MCTs are: caproic (C:6), caprylic (C:8), capric (C:10) and lauric acid (C:12) (1). So how do these particular fatty acids aid ketogenic and low carb high fat diets?

Due to the high-fat nature of a ketogenic or LCHF diet they have been considered to be potentially hazardous for those with cardiovascular disease (CVD).
Publicly available information (i.e. position statements and general patient information) from public health groups often include cautions against the use of VLCDs due to these perceived risks. Diabetes New Zealand states in their article on Low Carbohydrate Diets that “Eating more protein and fat may increase your risk of heart disease in the long term.” (1).
So are ketogenic diets dangerous for heart health?
