This is far easier than writing everything down in a food log, which the 44-year-old New Yorker did the last time he was fighting high cholesterol. At the end of each week, his nutritionist e-mails him a dietary critique. “I was never one for the whole food-log thing,” says Mr Katz, who owns a floor-covering business. “Now I'm doing better at keeping track of what I eat. I always have my phone with me—it's like having a conscience hanging on your waist.” Article URL: http://www.economist.com/science/tq/displayStory.cfm?story_id=4368140 Read 80 more articles from Economist sorted by date, popularity, or title.
