Well, for me I stay warmer even when others are cold. I dont mean my hands but my torso stays really warm. I get hungry more often and sometimes just famishes even though its only been 2 hours since I ate last. When I am asleep I wake up in the middle of the night sometimes hot and sweaty. I have had to use less covers over the last year. I eat 6 small meals per day for a total of about 1500 calories give or take. I also drink lots of water which also seems to make me warmer-go figure. My heart rate is also lower (in the 50's) too.
Hope this helps,
