New phone can exhale through the direct detection of burning fat
According to physicists organization network on August 12, Japan's largest mobile phone supplier NTT Docomo company developed a new smart phone external devices, users can by measuring the amount of acetone in the breath to get to know how much its burning fat, show the effect reducing weight. The equipment in comparison with high-grade laboratory equipment test reflects the advantage. Research is published in the latest issue of the journal respiratory research.
One difficulty is a lack of real time feedback to lose weight. Trying to lose weight usually do not show significant effect in the present. But people in the unstable, the transition state in the middle of the diet or exercise process, always wanted to know whether you're doing is right or have the effect. In order to solve this problem, the researchers found a can give dieters more immediate feedback information, namely, by measuring the amount of acetone in the exhalation.
Acetone is a kind of body fat decomposition of metabolites, when people are out in the exhale, thus can be used as a good indicator of fat burning. Measuring the general method for gas chromatography and mass spectrometry to measure, but these are expensive and cumbersome laboratory equipment is not suitable for daily use.
The newly developed equipment is portable and practical, and smart phones are roughly the same size. Its prototype are two different sensitivity characteristics of semiconductor gas sensor, in calculating the concentration of acetone and ethanol, hydrogen and humidity into account. Users can put a small pipe mouth, and then blowing, the device can measure the amount of acetone in the exhalation, accompanied by an encouraging news, equipment screen shows a pattern of the fat burning.
Need to stress is that the equipment is not a gimmick. The researchers recruited overweight volunteers to verify its accuracy. A group of volunteers were asked in a period of days in a small amount of exercise; Another group were asked to exercise and reduce the intake of calories; In a control group, neither cut calories or exercise. The researchers found that the device performance is almost exactly like accurate measuring acetone gas chromatograph, the level of their measuring way of acetone from exhalation showed a strong correlation between the results of concentration. In addition, the control calorie intake and exercise the body fat decreased obviously, and the breath of acetone concentration increased significantly.
Results show that the equipment for self-monitoring fat burning in the home is very practical, will help to prevent and reduce the risk of obesity and diabetes. It will be more and more combined with smart phone design, one of the medical equipment used in a time of crisis, not for the sake of entertainment equipment, will show strong growth trend in the future.
