CES 2013: connected fork 'helps you lose weight' Using an electronic sensor, the HAPIfork monitors how fast a user is eating and then alerts them if it is greater than a pre-determined rate. Over time, the device extends the length of time between mouthfuls so that the user eats less. The HAPIfork's makers claim that people only naturally feel full after about 20 minutes of eating, and so by diminishing the amount eaten in that period users will eat less and consequently lose weight. The project, which will be on Kickstarter and aims to retail for $99, also claims to reduce digestive problems and acid reflux. The HAPIfork is just one of a large number of new healthcare gadgets that are being launched at CES in Las Vegas, including Fitbug's new blood pressure monitor and new internet connected scales from Withings and Fitbit. The HAPIfork will initially connect via USB, but manufacturers HAPIlabs aim to introduce a bluetooth version shortly. Both will use a removable module so that the fork can be put in a dishwasher. It will track the duration of a meal, the number of fork servings and the duration of each interval between servings. If a user eats too frequently, it will vibrate while inside their mouth and show a warning light. "Most people eat faster than they should and do not realise that eating too fast ins't a healthy behaviour, negatively affecting things like digestion and weight control," said HAPIlabs" US President Andrew Carton. HAPIlabs also make an activity tracker, similar to Fitbit and Fitbug, called the HAPItrack. Both products feature web dashboards that aim to motivate users and introduce games to encourage improved behaviour.
