Previous studies in humans have shown that short to middle-term pre-exposure to multiple foods can reduce the negative response to novel foods (neophobia). In order to explore the effects of a long-term exposure to varied foods on food neophobia, we studied a population of obese adolescents observed in a longitudinal protocol in which the multiple food experiences are induced by a residential w...

BACKGROUND An estimated two-thirds of North Carolina residents are overweight or obese. Mass media, such as newspapers and the Internet, can be used to broadly convey health messages for weight loss. CONTEXT Newspapers have traditionally been a primary source of health information for the general public. They may be uniquely suited to initiate and manage a community-based weight loss program ...

OBJECTIVE Preliminary results indicated effectiveness of the online weight reduction program KiloCoach. The current study presents a large collection of user data and compares KiloCoach with other evaluated commercial weight loss programs. Furthermore, potential factors influencing the effectiveness of internet weight loss programs should be identified. METHOD 4,310 data sets of KiloCoach use...

Risk factors for arterial stiffness progression have not been well characterized. We examined the relationship between arterial stiffness progression and body weight and weight gain in a group of healthy young adults. Aortic pulse-wave velocity was assessed at 2 time points approximately 2 years apart in 152 white and black adults aged 20 to 40 years, and was standardized by the time between vi...

This analysis investigated if changes in autonomous or controlled motivation for participation in a weight loss program differed between individuals offered a financial incentive for weight loss compared to individuals not offered an incentive. Additionally, the same relationships were tested among those who lost weight and either received or did not receive an incentive. This analysis used dat...

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...

BACKGROUND New technology offers increased opportunities for weight control. However, it is not clear whether older people with less computer training can make use of this tool. Our objective was to examine how members above the age of 65 years performed in an internet-based behavioral weight loss program, compared to younger members. METHODS Data from members (n = 23,233) of an internet-base...

Weight-sensitive sports are popular among elite and nonelite athletes. Rapid weight loss (RWL) practice has been an essential part of many of these sports for many decades. Due to the limited epidemiological studies on the prevalence of RWL, its true prevalence is unknown. It is estimated that more than half of athletes in weight-class sports have practiced RWL during the competitive periods. A...

This experiment evaluated the efficacy of television delivery of a behavioral weight reduction program. Seventy-one overweight adults were randomly assigned to a live-contact weight loss group that was videotaped for viewing by other groups, a live-contact group that was not videotaped, a television-delivered group that observed the videotaped weight loss sessions, or a waiting-list control gro...

INTRODUCTION Obesity management guidelines specify initial goals for participation and weight reduction for the first 6 months of a weight-reduction intervention, but guidelines do not specify when to assess early response and make adjustments. We aimed to determine whether very early or early weight reduction in the weight-reduction program MOVE! predicted later participation or achievement of...
