I've just increased my water intake and NOW I am freezing too. The water is all room temperature, which is getting up there- near 80 now, I think. I really wasn't that cold before, but I knew I wasn't drinking enough. Now I just keep notching that heater up.

Yep, I agree that less insulation (body fat) is a factor, and reduced calorie could be another factor. When I was on my crazy 800 calorie a day diet (bad me! ) I was FREEZING all the time, I even had to wear socks to bed. And I live in a temperate part of California! Even on 1200 cals I felt chillier than normal.

Thanks for letting me know that it could be this WOL....I thought by "usually HOT" body was letting me down....I've never been cold like I have been the last two winters (both since I started LCing)! I'm glad that I'm not the only one wearing a few extra layers even if I am in the South!
