What it is: The Hapifork, $100 (hapi.com), has an electronic sensor that measures hand-to-mouth movements, then lets you know when you are eating too quickly.
Why: A meal isn't a race, and eating more slowly gives our brains and bodies time to register food intake so we don't overeat. In fact, research has shown that slower eaters tend to have lower body mass indexes than those who eat quickly.
Trail Run: I appreciate the taste and texture of food but apparently not enough, according to my Hapifork. I tested the utensil while eating a salad for lunch, and it lit up and vibrated whenver I placed food into my mouth too quicly-which was essentially every bite. I used to think that only adolescent boys scarfed down their meals at rapid-fire speed, but then I came to the unpleasant realization that I habitually shovel food into my mouth before barely finishing the previous forkful. Me, eating like a cavewoman! "Why didn't you tell me?" I wailed to my husband with the same fury I did the time he let me keep talking at a dinner party while I had spinach stuck between my teeth. He shrugged (probably because he chows down the same way).
