Technology to help obese  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 and how much food they consume.
The goal is to cut down on self-reported answers that often cover up what's really happening. Participants take turns sitting, standing, lying down, running on a treadmill and wireless sensors on their chests record their heart rates, stress levels and amount of physical activity.  Traditional weight-loss interventions rely mainly on people's memory of what they ate for dinner and how many minutes they worked out. But researchers have long known that method can be unreliable since people often forget details or lie. Researchers at the University of Pittsburgh have developed a new necklace device equipped with a video camera that records where a person goes and what he or she eats. read more visit smh.com.au
