Fight against fat goes high-tech with new devices

Some of these make sense since fat people lie about how much they eat and how much they move.

"The fight against fat is going high-tech. To get an inside look at eating and exercise habits, scientists are developing wearable wireless sensors to monitor overweight and obese people as they go about their daily lives.

The experimental devices are designed to keep track of how many minutes they work out, how much food they consume and even whether they are at a fast-food joint when they should be in the park. The goal is to cut down on self-reported answers that often cover up what's really happening."

Still won't work, though.
