Counting calories by cellphone

In Japan, where the battle of the bulge is a growing obsession, dieters can snap photos of their meals to send to nutritionists for analysis.

TOKYO — Wondering how much of a diet-buster that big bowl of noodles is?

In the United States, some restaurants could give you a calorie count. In Japan, you might take a picture of it with your cellphone and ask an expert.

With cellphones ubiquitous in Japan and concern rising over expanding waistlines, healthcare providers have put the two together to help the weight-conscious send photos of their meals to nutritionists for analysis.

The concept is only on a test run for now, and one drawback is that dieters have to wait three days to find out how much damage they did by eating the meal they just photographed.

Public health insurance officials in the Osaka region in western Japan have launched the service on a trial basis. About 100 heart patients signed up in the first year, followed by diabetes and obesity patients in the second.

"Japanese have been getting fatter, especially men in their 20s and 30s, and there is concern over what they learned about nutrition when they were younger," Osaka official Satomi Onishi said. "We're hoping that this program can help us to get a handle on the problem."

Osaka is using a system developed by Asahi Kasei Corp., a Tokyo-based chemical and medical equipment manufacturer. The system is operating at about 150 healthcare providers and local governments around the country, company spokesman Naoki Yoshimura said.

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 on to a website to get more dietary information and upload photos from digital cameras.

Dr. Yutaka Kimura developed a similar system at Kansai Medical University's Hirakata Hospital, also in Osaka prefecture. Five patients participate in the program, which costs the equivalent of $37 to join and $21 a month thereafter. Patients photograph meals over three to seven days, and a nutritionist e-mails back analysis and advice.

"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."

The battle of the bulge is a growing obsession in Japan, a country that is slowly losing its reputation for low-fat fish-and-rice diets and slim waistlines.

As Japanese have turned to bigger portions and more meat and fried foods, obesity and related illnesses such as high blood pressure have become a rising concern.

The Health Ministry estimated last year that more than half of Japanese men and about 1 in 5 women between ages 40 and 70 -- nearly 20 million people -- were at risk of metabolic syndrome, a term for a cluster of conditions associated with obesity, high cholesterol and increased risk of heart disease and Type 2 diabetes.

With the Health Ministry aiming to reduce by 25% the number of people at risk of metabolic syndrome by 2015, Osaka officials hope that the cellphone program will help.

"Cellphones are everywhere here," Onishi said. "We're hoping they can now make it easier for people to get help improving their diet."
