Brief Summary:
The investigators will test a recent mobile technology based (mHealth) behavioral weight loss intervention (W8Loss2Go), which is designed for children and adolescents, and uses an addiction model to promote withdrawal from problem foods, snacking, and excessive amounts at meals. The investigators will test whether this intervention will reduce body mass index (BMI), help subjects identify and withdraw from "problem foods", eliminate snacking, and reduce the amounts of foods consumed at home meals.

Arm Intervention/treatment
Experimental: W8Loss2Go App
Subjects will complete all stages of W8Loss2Go mHealth intervention.
Device: W8Loss2Go
The participants will proceed through all parts of the app program (problem food withdrawal, snacking control and withdrawal from excessive portions) and receive weekly phone calls from the study coordinator, who will be monitoring app usage and providing motivation. Subjects will return to the EMPOWER clinic for a three month weight check and face-to-face meeting with their mentor. After the study period, participants will again complete the EBQ, and be offered continued enrollment in the EMPOWER clinic or continued home use of the mHealth technology.

Primary Outcome Measures :
  1. Body Mass Index (BMI) z -Score [ Time Frame: Baseline and 6 months ]
    The Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean. Negative numbers indicate values lower than the mean and positive numbers indicate values higher than the mean. A negative change value reflects a decrease in BMI or a better outcome and a positive change value reflects an increase in BMI or a worsening in the outcome.

Secondary Outcome Measures :
  1. Number of Participants With Success in Withdrawing From Problem Foods [ Time Frame: 6 months ]
    The number of participants who were able to withdraw from 5 or more problem foods was evaluated.

  2. Number of Participants Able to Eliminated Day Time Snacking [ Time Frame: 3 months ]
    Success in these areas will be determined by data collected from within the application's database.

  3. Number of Participants Able to Reduce Daily Meal Portion Size Utilizing Wireless Food Scale. [ Time Frame: 1 month ]
    Success in these areas will be determined by data collected from within the application's database. Participants will weight meals daily and the app will assist the participant in decrease the quantity of food consumed each day until they achieve age appropriate portion size.
