A new study examined the use of the hashtag #childhoodobesity to track Twitter conversations about the issue of overweight kids.
Measuring 80 x 20 mm, the compact gadget fits comfortably into a pocket or a purse, while an accompanying app boasts a huge database of ingredients.
More than 10,000 backers joined the likes of Khosla Ventures and other angel investors, which brought more than $5 million to the company.
Users simply tell the app what food they are thinking of buying, eating or preparing, and they'll get images of suggested "tweeks" that remove calories.
The application will handle just about any drink, from basic sodas to fancy frappuccinos, and will know whether there's caffeine in it or not.
With the new service, users get better educated about their food choices and more committed to their nutrition and weight loss goals.
The service integrates with companion Humana fit app which is available for iPhone, Android and BlackBerry.
