Assessing the Bite Counter

Study Overview
=================
Brief Summary
-----------------
This study is designed to test the usability of the Bite Counter in an attempt to reduce participants' daily bites while also increasing their daily steps.

Detailed Description
-----------------
Self-monitoring is an important component of behavioral management of obesity. The Bite Counter is a wrist-worn device which detects the motions characteristic of taking a bite of food or a drink of liquid, to provide the wearer with a cumulative count of bites and sips over the day. In earlier studies the method was shown to accurately count bites across a wide variety of foods, utensils and subject demographics, and to provide an unbiased intake measurement. The proposed work will continue to improve the bite counting method by adapting to varying eating rates, develop a self-managed bite count-based weight loss protocol, and perform an independent test of the protocol. An improved Bite Counter device will also measure activity (steps).

| Other: Bites and Steps displayed<br>All subjects will be assigned to one arm-daily bites and steps displayed on Bite Counter device | Device: Bite Counter<br>* This study is a 15-week assessment of the possible utility of a wrist-worn device, the Bite Counter, in assisting the weight loss behavior change efforts of overweight and obese individuals. The Bite Counter tracks and analyzes wrist motions to identify those associated with taking bites of food and drinking beverages. It also has a step-counter feature. This study is designed to determine if using the Bite Counter with specific goals to reduce the numbers of bites and increase the numbers of steps will result in those changes.<br>|
