Cold Stomach = Burning Fat: Myth or Truth?

xnikkiheart

I heard that when you're working out (specifically running), if you're stomach's old to the touch, then you're burning fat. I've seen people on here say it, people on fitness blogs, and even a friend or two.
Granted, after I heard about it, I was at the gym and my stomach was cold too so there's obviously something about working out and cold stomachs. My problem is, if you're working out hard enough, the blood would be going to your arms, legs, lungs, etc and not be as focused in the core as it usually is, right? So from simple biology and anatomy logic, your core would be colder because there's less blood. I'm not completely sure this is true though.
I'm just wondering if anyone else has heard this and if there's any truth to it, or if it's just one of those old wives type workout tales.

Well, I do know from taking cellular and organ physiology that when the ambient temperature drops below the thermoneutral zone (the range of temperatures at which an organism can function without changing its metabolic rate), metabolic rate increases. So you would be burning more calories if you are in cold weather - say, 30F - than you would in mild weather - 65F, for example. When you are exposed to colder temperatures, your body will let your extremities go cold long before it lets your core go cold, to preserve optimal function of your vital organs, so no, I do not think blood moves away from your core and into your extremities when you work out.

And this is without the buffer of insulating layers, like hair, clothing, etc.

Maybe I worded that weird, but not that blood is necessarily moving away, I'm just confused because people are saying as you workout your stomach gets colder and that means you're burning fat (regardless of temperature). It just seems like a strange concept to me, maybe because I'm always burning up and sweating haha. I guess that makes sense if you're colder, you burn more calories (& maybe that's why my gym is always freezing).

So cakeums is that why taking cold showers is said to boost metabolism?
I live in a subtropical climate.

My stomach gets cold too.........but I just figured I was whacko or something. :frown:

Silverkittycat

Wow. I've never heard this one.
I'll probably be feeling my belly when I workout now.

If it brings your ambient temperature out of the thermoneutral zone, then I would suppose so, especially since body heat is lost much more easily to water than to air. However, I would think you'd need to be in there for quite some time to really see any significant effect. Being in too hot an environment can also raise metabolic rate, but not nearly as significantly as in a colder environment.

I've experienced that too...even running in hotter temperatures, my stomach and sides still feel cold to the touch later in the workout. I've also heard that it's from burning fat but I don't know of any scientific evidence that supports the idea! Interesting topic.

Myth. If it were true you could just sit at home and point a fan at your belly and lose weight.

Sorry, guys, but whatever muscles are being used are the ones that will get the most blood flow. If you are running, the blood flow gets directed to you legs, and therefore not to your stomach area. Also, when you run, you kick in your fight or flight response, causing blood to slow down to your digestive tract, which also makes the abdominal area seem colder. (This is medically backed up)

I think the cold belly question is whether it is a sign, not a cause.

This is true! When I do dance we know that we're burning fat when our stomachs are cold.. It dosen't matter what exersize you're doing it's always the stomach!

yellowstar247

Fat cells metabolize much slowe than other tissues, and thus release less heat. When you workout, your muscles produce considerably more heat as your metabolism spikes and everything but your fat heats up. Your fat does not becoeme cold, necessarily: it just feels cold compared to the rest of your body after exercising.

I have never heard of this.

bikinibeliever

I have no idea if this is true or not, but I have noticed when it is cold out and I walk (same distance and time) I burn more calories. I do not bundle up to walk so I feel cold to touch on most areas.

CarleyLovesPets

This also happens to me when I am on the elliptical and I have also heard that means you're burning fat.

Mine is hot.... runs off to cry

Mine never gets cold. I must not be burning fat.

Basically this.
