Diet and Weight Loss in Young Adults

2014-07-23 21:11:12 | BioPortfolio


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 obese young adults 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 group 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, and improved diet quality. This simple behavioral intervention will be feasible and will significantly increase water consumption among participants in the experimental vs. control group.


This is a 6-month randomized controlled trial. After the initial baseline screening and assessments, 60 obese young adults will be randomly assigned (30 subjects per group) to a standard weight-reducing diet with the advice to consume 8 cups of water per day (experimental group) or the same standard weight-reducing diet without additional advice (control group). The interventions will consist of nutrition education and behavioral counseling by a registered dietitian, during group workshops and telephone calls. Mobile text messaging will be used to reinforce information presented at the group workshops and thereby foster adherence to dietary advice. Diet prescriptions will differ only in regard to the specificity of recommendations regarding water consumption and physical activity recommendations will not differ between groups. The frequency and content of text messages will be consistent between the experimental and control groups, with the exception that the experimental group will receive an additional phrase with each message to encourage the "8 x8" water recommendation.

Participants will attend a series of monthly group workshops which include nutrition classes taught by a registered dietitian, cooking demonstrations, taste testing, hands-on activities and opportunities for questions and answers. A registered dietitian will also call participants every month to follow-up on their progress on the intervention they were assigned to and text messages will be sent on a daily basis.

Study outcomes will be assessed at baseline and at regular intervals throughout the 6-months of the study.

A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.

Iron or iron compounds used in foods or as food. Dietary iron is important in oxygen transport and the synthesis of the iron-porphyrin proteins hemoglobin, myoglobin, cytochromes, and cytochrome oxidase. Insufficient amounts of dietary iron can lead to iron-deficiency anemia.

Phosphorus used in foods or obtained from food. This element is a major intracellular component which plays an important role in many biochemical pathways relating to normal physiological functions. High concentrations of dietary phosphorus can cause nephrocalcinosis which is associated with impaired kidney function. Low concentrations of dietary phosphorus cause an increase in calcitriol in the blood and osteoporosis.
