I can appreciate the desire to eat when it is cold. I personally like herbal tea (without any sweetener) as a warm me up. If Celestial Seasoning brand tea is in your area, I'd suggest trying some of those. It warms you up without any calories or sweeteners. Food won't make you warm, but moving around will. Get up off your chair and move around a little. Check out some of the short sparkpeople fitness videos online. Just ten minutes. You can do it!
