The Gadget: Hapifork
($99, available in October; Hapilabs.com)
Goal: Curb mindless eating.
How it works: The fork buzzes when you take bites quicker than ten seconds apart.
Real-life road test: As O's health editor, I know that study after study has shown that mindless eating can lead to weight gain (the faster you eat, the more you eat). Could a high-tech fork fix that? After making stir-fry, I used the fork for the first time, and even though I was primed to expect the vibrations, I was surprised by how fast I ate. With every subsequent meal, it became easier to pace myself—and realize I didn't need as much food to fill me up.
Good idea or bad idea: Good—for a little while. It's impractical to use only one fork, but when I reverted to normal silverware, I still waited a few more beats between bites.
