BACKGROUND Obesity rates in adults continue to rise and effective treatment programs with a broad reach are urgently required. This paper describes the study protocol for a web-based randomized controlled trial (RCT) of a commercially available program for overweight and obese adult males and females. The aim of this RCT was to determine and compare the efficacy of two web-based interventions f...

Background. The repeated loss and regain of body weight, referred to as weight cycling, may be associated with negative health complications. Given today's obesity epidemic and related interventions to address obesity, it is increasingly important to understand contexts and factors associated with weight loss maintenance. This study examined BMI among individuals who had previously participated...

Results showed that a Navy-sponsored weight-reduction program was relatively successful in helping participants lose weight during treatment and throughout a one-year follow-up. Of the 531 women and 155 men who reported a mean weight loss of 22 lb and 28 lb, respectively, 32 per cent of the women and 29 per cent of the men responded that no weight had been gained during treatment and follow-up....

the purpose of this study was to examine the effect of aerobic training on levels of vascular and intracellular adhesion molecules in overweight middle-aged women. 20 sedentary obese women (mean+age: 46.1+6.88 years, bf%: 36.7+ 6.18, weight: 73.56+10 kg and bmi: 59.5+4.15 kg.m2) were selected and randomly divided into two groups. training program consisted of 50-60 min. running with an intensit...

Team-based internet interventions are increasing in popularity as a way of promoting weight loss in large numbers of individuals. Given that social networks influence health behavior change, this study investigated the effects of teammates and social influence on individual weight loss during a team-based weight loss competition. Shape Up Rhode Island (SURI) 2009 was a 12-week online program op...

OBJECTIVE This study assessed if lower than predicted serum leptin concentrations seen during weight loss persisted during weight regain, with possible implications for weight control. METHODS 115 children were investigated during a 12-week weight loss program. 90 children completed the program, and 68 children entered a follow-up program spanning 28 months. Measurements were performed at bas...
