Have you heard of the "HAPIfork?" Developers say it's a "smart" fork that can monitor exactly how much you eat.
The fork contains a motion sensor, so it can figure out when it's being lifted to the mouth. If it senses that you're eating too fast, it warns with you with a vibration and a blinking light. The company believes that using the fork 60 to 75 times during meals lasting from 20 to 30 minutes is ideal.
The makers claim that people only naturally feel full after 20 minutes of eating, and by eating less in that period of time, users will lose weight.
Between meals, you can connect the fork to a computer or phone and upload data on how fast you're eating, for long-term tracking.
The fork is expected to go on sale within months, and will cost $99.
