According to the 1999-2002 National Health and Nutrition Examination Survey, more than two-thirds of adult Americans over age 20 are overweight and a third of these are considered obese. And this population is exactly what Sprint's latest MyFoodPhone service is all set to target.

Sprint phone subscribers in the U.S can now avail themselves of this unique service to control their diets. So where do you start? Fill out a pre-defined dietary information form on the MyFoodPhone website - this includes statistics such as blood pressure, your current weight, the carbs, proteins, fats that you consume.Then, using your camera phone, you take pictures of your meals and send them across. After analysing these details, "nutrition advisors" from MyFoodPhone will send you a personalized 90-sec video by email telling you what you are doing wrong (or right). At $10 a month for the service (plus photo transfer fees), you get video-based advice from the nutritionists every 2 weeks.

The idea is that taking photographs of the food would tweak your conscience and help you eat (and exercise) right. But what if you don't take those photos? You would be forced to at least consider the $10 a month that you are shelling out.

So go ahead and gorge on all those delicious butter cakes . . . but just remember - your camera is watching!
