    • New Device Measures Fat Burn Rate



      From Science Daily

      Fitness fanatics may soon be able to gauge if their hard work is paying off without the need for weighing scales thanks to a new device that can instantly tell if your body is burning fat.

      The device has been presented today, 25 July, in IOP Publishing's Journal of Breath Research.
      Acetone is primarily produced in the blood when fat is broken down; however, it is also expelled through tiny sacs, called alveoli, in the lungs during exhalation and is therefore present in exhaled breath.

      This new device, which is capable of detecting acetone concentrations in the range of 0.2 to 50 parts-per-million, is just 10 cm long, weighs 125 g and requires two AA batteries to operate.

      Developed by a group of researchers from NTT DOCOMO Research Laboratories, the device consists of a pressure sensor to detect the exhaled breath and two types of semiconductor-based gas sensors to detect acetone.

      After a user blows into the device, the acetone concentration levels can be calculated and sent to a smartphone, either by Bluetooth or a cable, within 10 seconds.

      In their study, the researchers recruited 17 healthy adult volunteers (11 men and six women), whose body mass indexes (BMIs) were above the Japanese standard, to test the device.
      The volunteers were split into three groups, the first of which carried on with their normal life and were not restricted to a specific numbers of calories in their diet and not required to take part in exercise.

      The second group were required to take part in light exercise, such as jogging or fast walking, for 30-60 minutes a day and the final group were required to take part in the same exercise routine and also consume a limited number of calories in their diet each day.

      The experiment lasted 14 days and on each day before breakfast, the volunteers were required to measure their body weight, body fat percentage and breath acetone concentrations using the portable device and a standard instrument for comparison.

      Results showed that the volunteers in the first two groups -- those leading a normal life and those performing daily exercise -- were not able to lose significant amounts of fat. Their breath acetone concentrations also remained constant.

      The volunteers in the third group who followed the exercise regime and had their calorific intake restricted were able to lose significant amounts of fat and their breath acetone concentrations were increased significantly.

      Principal investigator of the study, Satoshi Hiyama, said: "Because obesity increases the risk of lifestyle-related illnesses, enabling users to monitor the state of fat burning could play a pivotal role in daily diet management. Current standard methods, however, are still not practically suitable for point-of-care instrumentation for diet-conscious people who wish to monitor their own fat metabolism at home or outside"

      "Considering that the effect of dieting could be estimated from changes in breath acetone concentrations, we've shown that our prototype is a practical and alternative checker that can be used in individual dieting programmes."

      "It is also known that when diabetes is out of control, patients have elevated levels of breath acetone. It is possible that our prototype could be used to assess how diabetic control is being managed at home."

        Ummm.. Do you think that having this is actually going to help obese persons to get fit? I don't. The information is already out there, everywhere, on how to drop fat. AND, they would still need to use that information.
        Now, this could be a handy device for some of us that are engaged in fitness regularly to see what kind of exercise modifications and diet tweaks can burn more fat.
        Obese people don't need a fancy gadget, they need motivation and self control.

        I think it will help show obese people how much better their diet needs to be in order to make progress with a regular exercise regiment. Is it going to "help"? NOPE. But.... If you eat poorly and still exercise your acetone breath levels don't change because you aren't burning fat. You have to be burning fat. How many obese people out there are exercising to no avail? LOTS

        It can help anyone who wants to know if they are simply burning fat AND how much they are burning. Awesome
