Current guidelines for obesity treatment recommend reducing daily caloric intake for weight loss. However, long-term weight loss continues to be an issue in obesity management. Alternative weight loss strategies have increased in popularity, such as intermittent energy restriction (IER), a type of eating pattern with periods of fasting alternating with unrestricted eating. The effects of IER on weight loss, cardiovascular risk factors, inflammation, and appetite are not clear. The purpose of this systematic review was to analyze short- (<24 weeks) and long-term (≥24 weeks) effects of IER on anthropometric, cardiometabolic, inflammatory, and appetite outcomes in adults with overweight/obesity. PubMed, CINAHL, Embase, and PsycInfo were searched from inception to July 2020. Human randomized controlled trials (RCTs) on IER with participants with a body mass index ≥25 kg/m2 were included in this review. A total of 42 articles (reporting on 27 different RCTs) were included. In short-term studies, IER showed pre-to-post treatment improvements in eight of nine studies that assessed weight. Weight outcomes were sustained in the long-term. However, no significant long-term between group differences were observed in fat mass, other anthropometric, cardiometabolic, inflammatory, or appetite outcomes. Compared to continuous energy restriction (CER), IER showed no significant long-term differences in anthropometric, cardiometabolic, inflammatory, or appetite outcomes in included studies. More long-term studies are needed to assess the benefits of IER on health outcomes.
Background: Educating and training clinicians to deliver nutrition interventions is critical to improve population health. However, the adequacy of nutrition education within primary care adult and family nurse practitioner (ANP/FNP) curricula has not been addressed. Purpose: The purpose of this study was to describe faculty perceptions of nutrition education in ANP/FNP programs. Methods: We used a cross-sectional design to gather data on nutrition education. The survey was administered to a convenience sample of faculty from the United States. Results: Our response rate was 47.8% (N = 49). The mean ± SD hours of nutrition education was 14.4 ± 14.6. One-fourth of schools reported that their students received at least 25 hours of nutrition education. Most participants thought it was very or extremely important (75.6%) that their students become more educated about nutrition. Conclusions: There is a need and desire for more nutrition education within nursing graduate curricula. Novel strategies to implement nutrition education in nurse practitioner curriculum are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
