    Feeling Cold While Fasting?

    Primal Fuel
    Does this happen to anyone else? I didn't have time for breakfast today so I skipped it. I had coffee with cream, but nothing else. Right now, my hands and feet are freezing.

    Is this a sign of a thyroid issue? Or is it just a normal reaction to fasting? I've noticed this a lot lately, and my hands and feet always warm up once I eat.

    I've fasted today and not noticed being cold. I thought the blood usually diverted to help digestion would get pumped around quicker\easier..

    I always get cold when I fast, so does dh. I think that's normal.

    I think it's perfectly normal. One morning during my fast, a friend of mine commented on how my fingers and toes "were freezing!" I may be wrong, but I have to imagine this is partly due to the fact that a calorie is a measurement of heat, so with a lack of calories comes a lack of warmth. Just my thinking.

    I guess it's not just me then! It's weird, but whatever. I usually don't notice until my hands are so cold that I sit on them at work... it's my body's way of telling me to eat, I guess.

    Could very well be a thyroid issue. Are you female? I don't believe fasting is healthy for most, if not all women.

    Do not allow yourself to become wrapped up in a food 'lifestyle'. That is ego, and you are not that.

    I noticed during long fasts 24+ hours that my body temp would fall a degree below normal. I think it's the bodies normal response, downregulating activity and metabolism to conserve energy.

    After a day or two of normal eating, it returned to normal levels.

    Yes, I'm female and I have thought I had a thyroid issue all my life (TSH is between 2 and 3 usually). Every doctor I've seen says that my lab results are "within range" and blows me off though, and I have seen several doctors about it, all CW but, regardless. So, yes, thyroid is what I'm worried about. I don't want to slow my metabolism anymore than it is slowed already!

    I don't even know why I'm fasting... it certainly hasn't helped with weight loss and that's really all I care about. I'm thinking maybe I should just go back to eating breakfast.

    I've noticed this for the past few weeks as well when I'm fasting. I was freezing in my office all morning and it actually felt perfect out in the 90 degree heat when I went outside. It has to be a side effect of the fast because I was always the guy that was hot and miserable going to turn up the A/C.... until I started IF. I have to say though, the changes by incorporating IF have been very noticeable (got me over a hump I've been stuck at for almost a year now even following a strict paleo diet) and are well worth the looks your co-workers give you when you are wearing a sweater in August.

    Being cold and having cold extremities is a sign of a lowered metabolism usually from lack of thyroid and of course calories. Not something to strive for.
