Public health insurance offices in the Osaka region in western Japan have launched a trial of a dieting service that allows users (heart patients, as well as diabetes and obesity patients) to take photos of their meals with their cameraphones and get expert advice about their diet, reports AP. It takes 3 days to get the results back so it’s not much use in deciding whether you should eat something new, rather whether what you normally eat is good. “Patients used to fill out meal logs, but people tend to forget things or underestimate their portions,” said Dr. Yutaka Kimura, who developed a similar system at Kansai Medical University’s Hirakata Hospital, also in Osaka prefecture. “Photographing meals and e-mailing them in is easier and gets more accurate results.”
