Ozzie, ((((((( HUGS )))))))

To answer your question from a medical prospective.... YES, it is possible for someone to get hot easier due to extra body weight, but it is also easy for a skinny person to be hot or cold at different times as well.
I am about 40 pounds over weight and I do NOT get hot, but I freeze to death and I live in a very warm state.... go figure.

I think it is more of the chemical make up of a persons body, than that of an extra fat gene, that makes a person cold or warm blooded.
