can undereating leave you excessively cold

i've noticed on the days that i don't have enough to eat either due to time, stress, etc. i feel incredibly cold and am constantly with goosebumps. i work in the same environment day in and day out and it has airconditioning but i don't think that it's just that sometimes the airconditioning is colder than usual. does anyone else get this way or think it may be because of undereating?

Could be a thyroid issue - I think feeling cold when others don't is one of the signs of an underactive thyroid.

when your body is "starved" of nutrients and essential vitamins & minerals needed for daily functioning, it starts to use the limited calories and nutrients to keep the vital organs working. if this didn't happen, you might be warmer, but your lungs might not be working, or your heart or your small intestine or whatever. the warning sign for your mind is the coldness you are experiencing. it's a warning signal that requires attention. please get your iron levels and electrolytes levels checked as well as your overall renal panel-low levels of magnesium & potassium can wreak havoc on your system, causing respitory and circulation problems. good luck!

I freeze in my office too. But it's not that I undereat I eat at least 1200 calories a day. I think that your body has to adjust to the weight you lose. I lost about 8 pounds, so for me, I think it has to do with that. It's only after the loss that I started freezing. I just bring a sweater.

Actually your vital organs are the last place your body goes to get energy since this could cause death. Muscle tissue is what gets burned after glycogen stores have been depleted. How are you doing, OP?

the point about using the available energy to keep vital organs functioning was made earlier. it seems that you may have interpretted it incorrectly. it is very important for the OP to get some kind of professional evaluation to be on the side of safety.

A couple of years ago I used to fast alot, up to a week at a time. And I would notice that I would get so cold I would have to take hot showers to get warm.

some people do it for cleansing. my uncle, who is a yogi, did it for 40 days. he cleaned out the waste and toxins from his intestines, liver, organs, blood, and other areas that way. He also did a dry fast for 1 week (really tough), meaning no water. No drinking water, didnt even touch water. There are a lot of reasons to do it.

I'm glad to know it's not just me..... I've lost 85 pounds w/ WW and I am cold alomst all the time. I do not believe that I am over-restricitng my calories, and I do not fast. My Dr., after a considerable battery of tests, indicated that somtimes it can take the body some time to adjust to a significant change in weight. But do see your Dr. as there can be many medical reasons for feeling cold.

I fasted for spiritual reasons. I suppose you could call it a cleansing of sorts.
Basically it is for the removal of all the un necessaries in life to focus on your creator and gain a closer relationship with Him.

losing weight made me cold

I lost ~70 lbs over five years, and I am still always the coldest person in the room. At my work I would wear long underwear and sweaters, and I even brought in an electric heating pad. My thyroid was checked but normal, and my doctors all dismiss a thyroid problem, as if I'm just looking for an easy solution. Particularly though, the last one said your periods won't be normal if your thyroid is off, and mine are fine.
I think my hypothalamus is just permanently screwed up (the same part of the brain controls body temp and appetite). I try to keep myself warm because when cold I overeat. Unfortunately, the main solution I've found is to drink coffee all day. Also, after the weight loss I've had somewhat low blood pressure, which is probably part of it. If you have ruled out serious causes, you may just have to be the weirdo with the sweaters and the long underwear, like me :)

change the behavior

When you undereat your metabolism slows down, Your body uses energy to perform metabolism and as we all know heat is a byproduct of metabolism so you get cold, also when you don't eat enough protein the albumin in your blood stream is decreased which, lets just say it throws off circulation and causes you to feel colder, another contribution to being cold is that when you lose fat an insulator of heat your body is not so efficient at keeping in the heat which you notice because for so long you had that insulation and all of a sudden its gone. Why don't we just do all of ourselves a favor and eat proprely instead of worrying about whether or not we had enough to eat and while your at it you can go exercise which can boost metabolism, warm you up and allow you to eat enough protein your body needs to sustain yourself. I don't mean to sound rude but if you know your undereating just correct it with a little ingenuity.
