Oh I know that that effect is there and it explains why some people
can "over eat" to some degree without a net weight gain over time but
it's usually an excess of carbs that triggers adaptive thermogenesis.

Most fats are delivered to the tissues too slowly to produce this
effect, the exception being medium chain triglycerides which are
immediately oxidized by the liver and can produce a noticeable thermic
effect which is why I suspect is happening with the pound of butter.
There may be enough MCTs in a pound of butter to heat you up. If this
is true then it would be more efficient (and more healthy) to carry
MCT oil in cold climates instead of butter.

Diglycerol oil is metabolized the same way as MCTs which is why the
makers of Enova are claiming that it's so great for dieters but over
time it's still calories in vs calories out.
