Official title
A 6-Month Study on Diet and Weight Loss in Overweight Adolescents
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Advice to increase water consumption as part of a weight-reducing diet - typically to 8 cups (64 fl oz, \~2 L) per day ("8x8" water recommendation) - is almost ubiquitously recommended by healthcare professionals. Many believe that water promotes weight loss through numerous physiological mechanisms. However, only limited observational data and virtually no experimental data exist regarding the effects of water consumption on body weight. In this study, we propose a randomized controlled pilot study in which two groups of overweight adolescents will receive a standard weight loss regimen, either with (experimental intervention) or without (control intervention) additional advice and support to increase water consumption. We will utilize individual sessions, an innovative text messaging protocol, and motivational telephone calls to promote adherence to the interventions. The purpose of this pilot study is to evaluate feasibility and obtain preliminary efficacy data, to inform design of a future, definitive study. It is hypothesized that increasing water consumption will improve the efficacy of a standard weight-reducing diet and will lead to decreased consumption of energy-containing beverages, decreased total energy intake, improved diet quality, improved immune status, and improved cardiovascular and diabetes risk factors. This simple behavioral intervention will be feasible and will significantly increase water consumption among participants in the experimental vs. control group.
