Yes, this thread has grown like the mythic Topsy.

I have no idea about feeling warm after a fat meal. I think it is probably due to some other cause, unrelated to eating... like standing over a sink of hot water... But I must admit to not knowing of any cause- or of any other case.

It is very common to flush with warmth after ingesting sweets or sugary drinks, since the body produces some waste heat during glucose to fat conversion, but fatty zero-carb meals are- to me at least, heat-neutral or cooling.
