Obesity, that is one of the health issues that keeps on haunting over the minds of the fitness freaks all the time and to get over this most conscious health problem, there a good number of ideas has been searched out and practiced by millions of fitness freaks around the globe.

However, it is indeed an innovative idea to fight obesity while going high –tech. As to look over the estranged eating habits developed and followed by people in recent times, scientist has been successful in developing wearable wireless sensors to have an observation of obese people as they move around carrying out their chores. The newly developed sensing devices keep track of every thing from the food consumed or workout done by them.

These wireless sensors can be plugged to the chest to record the heart rate, stress level and physical activity of the patient. These sensors definitely has an edge over traditional weight loss interventions as people mostly rely upon their memory as to tell what they ate out in dinner and how much they indeed have ate out.  These devices are made upon on similar pattern as to track calories burned by measuring motion, sweat and heat with armbands. The devices sometimes are upgraded to the preciseness of having video cameras. More experiments on these devices are on at the University of Southern California Lab.

According to the other researches done with advancement of technology these devices are made possible by accelerometers which can measure out duration and intensity of a workout. More amazingly, these devices can be used with Bluetooth enabled cell phones which can take pictures of meals taken and can send back that information.

Another major project for obesity control is going under at Pennington Biomedical Research Center in Louisiana where it has been checked out that how technologies can help in reducing fat.  At research at university, the participants take picks of their meals and leftovers with the help of Blackberry Curves. At the same time they also wear quarter sized device on their shoes to count the number of steps they take. Counselors over there adjust over incoming data and provide individually tailored health advice through e-mail or telephone.

However, many ethical questions have been raised over issue as how much a device can track over one’s eating habits and there would be a check on one’s personal habits and preferences.
