Lack of body heat

savageman69

Anyone else have this...I know ive lost lots of weight but how long before my body adjusts? Its not even winter yet and im freezing all the time.

I'm not sure it ever goes away!

My body has never adjusted to not having it's layer of fat for insulation. I get cold really easily and always just make sure to have a sweatshirt or jacket in the car just in case.

But, I've also had all of my vitamins and minerals tested, along with a few other tests, and know that it's not a deficiency of any kind that's causing it either. But being low in iron can cause you to feel cold a lot, so can thyroid issues and some other medical reasons. So you can always call an advice nurse or contact your doctor and get checked out to make sure it's not anything other than just the weight loss itself.

Other day i was wearing t shirt and 2 hoodies and still cold lol....I was hoping it was just a temp thing most skinny guys i know dont get cold often...I know when i had the weight on i was always to hot lol cant win

My friends that are skinnier than me, that were always skinny, don't get cold either. My other friends that have lost weight like I have, you can tell which ones we are because we're the ones shivering in three layers of clothing talking about how we miss our fat on those nights. lol

There is another very valid reason that inability to stay warm happens.

Hormones for women of course with PMS.

Lack of insulation of fat.

But frankly, the body should have the energy reserves and ability to increase metabolism slightly to increase heat.
Of course, you get to cold and it is indeed going to shiver and all the normal functions to raise core temp.

But during this stage, the other reason....

You may not be eating enough.

Really. If after exercise, or even with no exercise, if your body isn't getting enough calories/energy to take care of the basic metabolism functions, then some higher level functions are let go. The base metabolism has just so many calories it needs to perform it's functions. MFP - Tools - BMR calc shares that estimate.
If it doesn't get what it would like to burn, it'll slow somewhat, and to have remaining calories to use, cause other things to not be done.

Like staying warm. Like repairing muscle. Like growing hair/skin. Ect.

One of the first things reported by those that started eating at a more reasonable deficit in the winter - warmer.
Which makes sense, because metabolism is fundamentally heat. Energy used by your body, heat produced as by product. Besides the body's ability to create heat when needed when you are cold.

Or at least, it should be able to.

You could increase your lean body mass. I'm always hot when everyone else is cold.

Or become a woman--menopause has solved my cold all the time problem--now I'm only cold half the time and drenched in sweat the others, regardless of whether I'm working out.

I told my friend at work the other that I don't understand how skinny people can stand being cold all the time!! haha I always have to have a heater on at my desk and a jacket or sweatshirt close-by now.... hahaha

Yes this is my main goal but at the moment...on strike at work so i gotta take a break from the gym but i will return and hit it hard again right now just trying to get super lean so i have a clean base to build on

Ditto. If you have lower lean body mass, you will be colder. I think this is the case generally whether you have lost or already skinny.

I too am skinny and I am cold anytime the temperature drops any appreciable amount.
I used to go to Hawaii fairly often and I was the one guy sitting there in a sweat shirt in the evenings. That is because it never really gets hot there. It is just always in the 70s.
That said, I think it unlikely that this has to do with a lack of body fat. Even when your body fat percentage is really low, you still have a layer of fat that can be 1/8-1/4 inch thick under your skin. Ask any dermatologist.
I spoke with a medical researcher once who studied how good an insulator that layer of fat is. He said he believed that the layer of fat most people have, even on boney parts like knees and wrists, is so good at keeping the cold out that he thinks icing an injury does very little good.
I know that people obviously do get cold. But, given what this researcher said, i think being cold probably has more to do with not regulating your temperature well.

Yep, one of my complaints as well. I dont think it goes away. I have 2 sweaters and a coat a work and everytime I go to the grocery store I bring a jacket. I get distracted by being cold. ha

You know...I used to be 370 and I was always hot. It could be 20 degrees outside and I was out in a t-shirt.
Tonight it was 65 out...and I was shivering as I was walking...

I'll take the shivers...but I used to set my AC to 60...and now I can't tolerate 65? ô.o

LOL, and that's a bummer too, because a drenched shirt will be even colder when the heat goes away.
