Where Does All Our Fat Go When We’re Losing Weight?

Where Does All Our Fat Go When We’re Losing Weight?

As a new year begins, one of the most popular resolutions that many of us will have made is to lose some weight and get healthier. By now you have probably been inundated with numerous ads, emails, websites, and articles about the best diets and exercise techniques you should be using to ensure you’re a prime human specimen by summer.

I’m currently partaking in the 30 Day Shred, and although I feel better I’m not really seeing a huge difference so far. So I started thinking: where does the fat go as we lose weight? Like many others, I have always thought that fat is converted into energy and used as heat or to build muscle. However, recent research suggests this may not be the case. In fact, one study says that losing weight may literally be as simple as breathing.

Back in March 2014, Professor Andrew Brown of the University of New South Wales was working with Australian TV personality and former physicist Ruben Meerman on an ABC-TV program, Catalyst Science. Meerman lost an impressive amount of weight in 2013 and had been interested in discovering how the fat was leaving his body.

“I lost 15 kilograms in 2013 and simply wanted to know where those kilograms were going. After a self-directed, crash course in biochemistry, I stumbled onto this amazing result,” Meerman writes. “With a worldwide obesity crisis occurring, we should all know the answer to the simple question of where the fat goes. The fact that almost nobody could answer it took me by surprise, but it was only when I showed Andrew my calculations that we both realised how poorly this topic is being taught.”

After their initial meeting the duo then spent several months investigating the different ways fat leaves the body as we work it off. Their results, which were published in the British Medical Journal in mid December, are rather astonishing: we lose weight as we breathe out, or as Meerman says: “it goes into thin air.”

    How Does It Work?

    When we consume excessive carbohydrates and proteins they are converted into chemical compounds known as triglycerides, which consist of carbon, hydrogen and oxygen. These triglycerides are then stored in lipid droplets of fat cells, where they wait to be metabolized.

    Meerman and Brown’s experiments tracked atoms of fat as they were metabolized to see where they went, and found that the majority of them exited our bodies as carbon dioxide.

    They then calculated that in order to lose 10 kilograms of fat, humans must inhale at least 29 kilograms of oxygen. This in turn produces 28 kilograms of carbon dioxide and 11 kilograms of water. A massive 8.4 of those 10 kilograms is exhaled through carbon dioxide. The other 1.6 kilograms of fat is excreted as water, via urine, sweat, tears, breath and other bodily fluids.

      Meerman’s findings are now being investigated and praised by many in the scientific community. Professor Brown stated: “Ruben’s novel approach to the biochemistry of weight loss was to trace every atom in the fat being lost and, as far as I am aware, his results are completely new to the field. He has also exposed a completely unexpected black hole in the understanding of weight loss amongst the general public and health professionals alike.”

      Of course, although it turns out that lungs are the primary organs for excreting weight loss, the authors do not recommend you simply breathe a lot in order to lose weight quicker. This will inevitably lead to hyperventilation and possibly even loss of consciousness.

      Brown and Meerman are now focusing on trying to get secondary schools and university biochemistry curriculums to include their findings in an attempt to correct any spreading misconceptions about weight loss.

      8 Smart Home Gadgets You Need in Your House

      8 Smart Home Gadgets You Need in Your House

      We’ve all done it. We’ve gone out and bought useless gadgets that we don’t really need, just because they seemed really cool at the time. Then, we are stuck with a bunch of junk, and end up tossing it or trying to sell it on Ebay.

      On the other hand, there are some pretty awesome tech inventions that are actually useful. For instance, many of the latest home gadgets do some of your work for you, from adjusting the home thermostat to locking your front door. And, if used as designed, these tools should really help to make your life a lot easier—and that’s not just a claim from some infomercial trying to sell you yet another useless gadget.

      Take a look at some of the most popular “smart gadgets” on the market:

      1. Smart Door Locks

      A smart lock lets you lock and unlock your doors by using your smartphone, a special key fob, or biometrics. These locks are keyless, and much more difficult for intruders to break into, making your home a lot safer. You can even use a special app to let people into your home if you are not there to greet them.

      2. Smart Kitchen Tools

      Wouldn’t you just love to have a pot of coffee waiting for you when you get home from work? What about a “smart pan” that tells you exactly when you need to flip that omelet? From meat thermometers to kitchen scales, you’ll find a variety of “smart” gadgets designed to make culinary geeks salivate.

      3. Mini Home Speaker Play:1

      If you love big sound, but hate how much space big speakers take up, and if you want a stereo system that is no bigger than your fist, check out the Play:1 mini speaker. All you have to do is plug it in, connect, and then you can stream without worrying about any interruptions or interface. You can even add onto it, and have different music playing in different rooms.

      4. Wi-Fi Security Cameras

      These are the latest in home security, and they connect to the Wi-Fi in your home. You can use your mobile devices to monitor what is going on in your home at all times, no matter where you are. Options include motion sensors, two-way audio, and different recording options.

      5. Nest Thermostat

      This is a thermostat that lives with you. It can sense seasonal changes, temperature changes, etc., and it will adjust itself automatically. You will never have to fiddle with a thermostat dial or keypad again, because this one basically does all of the work for you. It can also help you to save as much as 12% on heating bills, and 15% on cooling bills.

      6. Smart Lighting

      Control your home lighting from your remote device. This is great if you are out and want to make sure that there are some lights on. It is designed to be energy efficient, so it will pay for itself over time because you won’t have to spend so much on your monthly energy bills.

      7. Google Chromecast Ultra

      Whether you love movies, television shows, music, etc., you can stream it all using Google Chromecast Ultra. Stream all of the entertainment you love in up to 4K UHD and HDR, for just $69 monthly.

      8. Canary

      This home security system will automatically contact emergency services when they are needed. This system offers both video and audio surveillance, so there will be evidence if there are any break-ins on your property. You can also use it to check up on what’s happening at home when you are not there, including to make sure the kids are doing their homework.
