About the Study

Is Your Teenager Overweight?

Currently one third of adolescents are overweight or obese, a rate that has tripled over the past 30 years and is a major national concern. Besides excess weight, many adolescents have co-morbidities or are at an increased risk for these comorbidities in the future.

The POWER (PrOtein and WEight loss in teenageRs) study will determine the effects of two weight loss diets that have higher and lower dietary protein intake on body weight in adolescents 12-17 years of age. 

Study Design

  • 1 screening visit
  • 4 clinic visits
  • 8 intervention visits

Study procedures:

If your child agrees to volunteer for the study and is eligible, your child will be randomly assigned to 25% energy restriction with one of 2 programs:

  • Lower Protein Group or
  • Higher Protein Group

Adolescents in both groups will be required to wear an accelerometer and record their food intake via camera phone. The intervention visits entail meeting with a weight management counselor once a week for the first month, then every other week for the next two months. At the end of 12 weeks, both the child and the parent will return to clinic to have the measurements done at Screening repeated. A parent or guardian must also agree to participate to allow collection of anthropometrics and demographic data to better understand the home environment. All study procedures will be provided at no cost to participants.
