Food tracking app links less sleeping to more eating

The trouble with eating or drinking over a longer stretch of waking hours and consuming more calories at night is that "it confuses our body's biological clock and predisposes us to obesity, diabetes, fatty liver disease, high cholesterol and cardiovascular disease," Panda added by email.

Because many existing apps and food diaries can encourage people to eat less just by seeing what they record, Panda and co-author Shubhroz Gill at the Salk Institute devised an app that would erase data as soon as images were logged. This meant the app should have minimal impact on how people ate, Panda said.

Based on an analysis of snapshots recorded by more than 150 volunteers, the researchers got a sense of what people ate when, and under what circumstances.

They could see, for example, what people photographed next to a keyboard, in bed, watching television, or walking down the street.
