An iPhone app called The Eatery asks people to take pictures of their food and rate other people's pictures based on its healthiness. This week, the health start-up that created the Eatery, Massive Health, released data they've gathered from the thousands of people that use their app, and are hoping to use that information to improve eating habits.
The findings show that Copenhagen is ranked as the healthiest city, followed by San Paolo, New York City, San Francisco, Tokyo, and Philadelphia.
The app has helped to uncover intriguing eating habits among its users. "People eat 1.7% less healthy after each hour that passes in the day, presumably as their willpower erodes. That means breakfast is usually the healthiest meal, while dinner is the unhealthiest," notes Schwartz.
The Eatery is already helping its users to eat healthier. According to Massive Health's co-founder Aza Raskin, "Users ate 8% better (based on crowdsourced food rankings) after 30 days, and 11% better after three months. "It's addicting. People will take a picture of their food and rate 20 or 30 other pictures after," he says.
In the future, Massive Health hopes to delve into other health-related areas concerning stress, exercise and sleep.
