By Kathleen DohenyTHURSDAY, July 25 (HealthDay News) A new, portable breathalyzer that pairs with a smartphone and Bluetooth can measure how well you're burning body fat and help you gauge the success of your diet and exercise program, according to a new report from Japan.
One strength of the study, he said, is that the device results were compared with those of a "gold standard" test. "They did compare their device with gas chromatography and reported a strong correlation," he noted.
"I think it's an interesting device," said Larry Birnbaum, a professor and chair of exercise physiology at the College of St. Scholastica, in Duluth, Minn., who reviewed the findings and has researched fat burning. He pointed out some limitations, including the small study size of 17 people.
In the future, Birnbaum said, if the device research bears out, it could provide people an additional piece of information. "It might help people stick with a diet; it might help them modify their diet.".
Those in the third group who followed instructions lost substantial amounts of fat and their breath acetone levels rose.
One group carried on with their normal routine, with no instructions to exercise or restrict calories.

Hiyama and his team had assigned the participants to one of three groups for the 14 day study. All were overweight by Japanese standards. standards, for example.)
To operate the device, the user blows into it and the acetone concentration levels are calculated and sent via Bluetooth or cable to an Android based smartphone. It takes about 10 seconds.
"Enabling users to monitor the state of fat burning could play a pivotal role in daily diet management," Hiyama said in a journal news release.
Each day before breakfast, the men and women used a bath scale to weigh themselves and measure body fat, then used the breathalyzer.
The researchers speculate that the device might also be used in the prevention and treatment of diabetes. When diabetes is out of control, acetone breath levels rise.
The researchers tested the device in 17 healthy men and women, reporting their findings online July 25 in the Journal of Breath Research.
throughout our experiments," Hiyama said.

A second group was required to take part in jogging or fast walking from one half hour to an hour a day. The third group did the same exercise routine but also was instructed to restrict calories.
Hiyama could not say what the device might cost or how soon it could be on the market.
For the study, after people blew into the breathalyzer, they also blew into a special collection bag that was measured with the conventional chromatography method.
The device measures acetone, a metabolite produced from fat burning. When you burn fat, acetone levels rise in the blood, but are also exhaled. The new device is as reliable as a "gold standard" test (such as gas chromatography) to measure acetone, according to Satoshi Hiyama, senior research engineer at NTT Docomo, a Japanese mobile communications company.
two groups did not lose substantial amounts of weight their breath acetone levels were constant. The researchers suggested that the exercise only group members, allowed to set their own pace, weren't working hard enough.
"That is good," Birnbaum explained. But he added that validity would be enhanced if independent researchers repeated that comparison. The Nike Vapormax Shoes 2018 device also needs to be tested on a larger number of people with varying levels of acetone in their blood and breath, he said.
"We found that the concentrations Mens Nike Vapormax Black

At this point, the device is only a prototype. It's pocket sized, about 4 inches long, and weighs about 4.5 ounces. It operates on two AA batteries.
