The evidence in words
What it is
MCT oil supplies medium-chain triglycerides (C8/C10) that absorb and metabolize faster than long-chain fats.
How it works
MCTs are absorbed directly to the liver and readily converted to ketones, providing quick energy and a ketone bump useful on ketogenic diets.
What the evidence shows
MCTs modestly increase energy expenditure and satiety versus long-chain fats and reliably raise blood ketones (relevant to keto and some cognitive-in-impairment research). Standalone fat-loss effects are small and easily offset by the added calories. GI distress is dose-limiting.
How to use it
Start with 5–10 g and titrate to tolerance; common on ketogenic and endurance protocols.
Safety & interactions
GI upset (cramping, loose stools) at higher doses; caloric density matters.
Bottom line
Handy fast energy and a ketone boost for keto or endurance use. Not a fat-loss shortcut — the calories still count and the gut sets the ceiling.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
- 5–10 g, titrate to tolerance.
