You don't have to be underweight to start getting the chills that come with starving yourself. Abnormally low iron levels (anemia) causes low body temperature as well. Just plain not eating enough has the same effect, I've found.

It hasn't exactly happened to me again this time around (lol weird), but last time I was dropping weight I started becoming incredibly cold in the BMI 19 range. It's not unusual and doesn't always have to do with body fat.

 

at bmi 19 you can have low enough body fat % for that

bmi is just a general rule of thumb

 

im obese but still anemic and i get cold everyday. even though i'm over weight i don't really eat anything so i ended up being anemic, you don't have to be underweight to get it you might want to get checked because if you get to a really low number you have to get a blood transfusion and stay in the hospital for two weeks ( my own experience). i hope everything works out for you if you want to raise your iron levels i recommend beets smoothies i just do it with water not milk too many calories but it helped me with my anemia

 

even if you're not technically underweight you can still be less tolerant of the cold than most people if you're on the lower end of average. my bmi is in the 19s & i can't stand the cold

also, if you lost a significant amount of fat recently you'll likely be colder than you're used to, regardless of your current weight.

 

Coldness has to do with malnutrition not weight

 

i used to always be cold at bmi 24... now im 19 bmi and im never cold... (altho i still have ed) so it really doesn't depend on your weight.. more about vitamins metabolism and stuff

 

You could be anemic. I'd recommend a blood test, unless you're in the US (where I got a fuckin $900 bill for an anemia test lmao).

I do live in the US, unfortunately. ): Are they always that expensive?

 

I’m at a BMI of 28 and I’m freezing 24/7. It’s so not related to weight.

i also live in the states in NC i paid 50 dollars for a blood test that told me i had anemia and i didn't have insurance at the time so try to find a clinic and ask around for prices.

 

At that Low of a BMI you can definitely be cold all the time. Plus I am always cold and have a higher BMI than that as my body is most definitely in starvation and your stomach may be as well.

Are you on any meds? I take one that changed me from always being hot and sweaty to cool/cold and I almost never sweat anymore. The med papers say it could cause body temp changes. I love it! I live in a very hot climate so being cold is way better than hot! Of course, sometimes I get so chilled my teeth chatter and I shiver for no good reason. Those are the times I think the cold is from fasting/restricting. But you gotta take the good with the bad. And I choose cool.

 

i'm the same, i'm like 19.5 bmi- or somewhere round there

i think it has something to do with nutrition idk tho

 

I've always been cold all the time even when I was over 130. Not surprised you're cold at that bmi.

 

I get cold when I eat less than 1200 calories regularly and I’m at BMI 24.7, so I’m usually freezing too

 

Take ya multivitamins and B-12's and all the other B vitamins (they, particularly b-12, are important for red and white bloodcell levels).​

 

For me personally it's more to do with intake rather than weight/ BMI... if I'm low restricting I'm always cold, even when it's summer in Australia and I had a healthy BMI. These days I'm either high restricting or eating up to maintenance at BMI 15, and I never get cold...

Are you restricting? You could absolutely be cold from lack of nutrients at Any weight.
Layer up!!! You can take OTC supplements and see if they make a difference? Iron causes OD at a lower than average xose - roughly 800% at the low end for some people, so be just be warned to read labels.
