flag A Penn State AI system tracks kids' bite rates to help reduce obesity risk by encouraging slower eating.

flag A new AI system called ByteTrack, developed by Pennsylvania State University researchers, aims to combat childhood obesity by tracking bite rates during meals. flag Trained on 1,440 minutes of video from 94 children aged 7 to 9, the AI identifies faces with 97% accuracy but counts bites correctly about 70% of the time, struggling with obscured faces or children chewing utensils. flag Faster eating is linked to higher obesity risk due to reduced fullness signals. flag The system could eventually power smartphone apps to prompt children to eat slower, supporting healthier habits. flag The study was published in Frontiers in Nutrition, and experts say targeting bite rate may help reduce overeating and obesity risk.
