Wondering how much of a diet-buster that banana cream pie on your plate is? Some Japanese have a novel way to find out: Photograph it with your cell phone and send the image to an expert.
With cell phones ubiquitous in Japan and rising concern over expanding waistlines, health care providers have put two and two together to allow the calorie-conscious to send photos of their meals to nutritionists for analysis and recommendations.
Nutritionists can work with photos from one day's meals to several weeks' worth, he said. Results come back in three days. Participants also can log onto a Web site to get further dietary information and upload photos from digital cameras.
"Patients used to fill out meal logs, but people tend to forget things or underestimate their portions," Kimura said. "Photographing meals and e-mailing them in is easier and gets more accurate results."

This seems like a very interesting use. You make full use of the data plans, you lock customers into an additional service that can provide a cut to the carrier, and has a peer pressure level. You see a friend or colleague doing this, and such a service will appeal to you as well.
Also, with obesity increasing, customers are more likely to use such a service, and if it can help reduce the obesity levels, then it will be a big boon for people.
