Obesity Problems 30% of U.S. adults (20 years or older) are obese
◦ 60 million people
65% of U.S. adults are considered overweight
16% of children/teens (ages 6 – 19) are overweight◦ 9 million people
Estimated annual cost of obesity in the USA in 1998 was $78.5 billion, 2000 was $117 billion
According to the CDC, the main cause is poor eating and exercise habits
• UC San Diego 2006-07• Wireless food intake systems
• Mobile phone application that allows users to monitor their caloric balance• Monitors
• The number of kilocalories eaten and burned during the course of a day
• Limitation• The selection of foods is manual • Not all food items are listed The user should estimate number of kilocalories ( Loss of accuracy)
Example
Monitors caloric balance in real time◦ User input : i) Barcode Scan
ii) Manual Keyboard Entry◦ Connects with various DBs ◦ Provide ingredient lists and nutritional
information◦ If food choices are inconsistent with the
Dietary Guidelines for Americans, Give reminders
Ex) you are 50% over your daily energy density intake goal

Conclusion We propose
◦ A handheld system that is constantly with the user
◦ A (mostly) automatic and accurate way to enter names of foods
◦ A method to track user consumption and trends over time
◦ A system that can be programmed to warn the user against unhealthy food choices
Future Work Support non-UPC food
◦ Ex) processed fruits and vegetable
Able to enter any dietary restrictions◦ More than nuts
