In today's society, snacking contributes close to one-third of daily energy intake, with many snacks consisting of energy-dense and nutrient-poor foods. Choices made with regard to snacking are affected by a multitude of factors on individual, social, and environmental levels. Social norms, for example, that emphasize healthful eating are likely to increase the intake of nutrient-rich snacks. In addition, satiety, the feeling of fullness that persists after eating, is an important factor in suppressing overconsumption, which can lead to overweight and obesity. Thus, eating snacks between meals has the potential to promote satiety and suppress overconsumption at the subsequent meal. Numerous studies have explored the relation between snack foods and satiety. These studies concluded that whole foods high in protein, fiber, and whole grains (e.g., nuts, yogurt, prunes, and popcorn) enhance satiety when consumed as snacks. Other foods that are processed to include protein, fiber, or complex carbohydrates might also facilitate satiety when consumed as snacks. However, studies that examined the effects of snack foods on obesity did not always account for satiety and the dietary quality and portion size of the snacks consumed. Thus, the evidence concerning the effects of snack foods on obesity has been mixed, with a number of interventional and observational studies not finding a link between snack foods and increased weight status. Although further prospective studies are warranted to conclusively determine the effects of snack foods on obesity risk, the consumption of healthful snacks likely affects satiety and promotes appetite control, which could reduce obesity.

Ayurveda, the traditional medical system of India, is understudied in western contexts. Using data gathered from an Ayurvedic treatment program, this study examined the role of psychosocial factors in the process of behavior change and the salutogenic process. This observational study examined associations with participation in the 5-day Ayurvedic cleansing retreat program, Panchakarma. Quality of life, psychosocial, and behavior change measurements were measured longitudinally on 20 female participants. Measurements were taken before the start of the program, immediately after the program, and 3 months postprogram. The program did not significantly improve quality of life. Significant improvements were found in self-efficacy towards using Ayurveda to improve health and reported positive health behaviors. In addition, perceived social support and depression showed significant improvements 3 months postprogram after the subjects had returned to their home context. As a program of behavior change, our preliminary results suggest that the complex intervention Panchakarma may be effective in assisting one's expected and reported adherence to new and healthier behavior patterns.

Background. Lifestyle behaviors have a significant effect on preventing and treating disease, yet there is minimal graduate medical training in lifestyle medicine (LM). LM stakeholders' perspectives regarding components of a LM fellowship have been examined. However, the student perspective has not been studied. Methods. A cross-sectional study design analyzed medical student perceptions surrounding LM domains and educational experiences. A Kruskal-Wallis analysis of variance and a Wilcoxon Rank-Sum Test were performed for each topic. Results. In all, 21 medical students completed the survey. All domains (nutrition, physical activity, behavior change, stress resiliency, and personal health), except smoking cessation, were rated as important or very important by at least 75% of the respondents (P = .002). The 4 highest-rated educational experiences, by at least 69% of respondents, included developing LM interventions and health promotion programs, clinical experiences, and teaching other health care providers about LM. Significant differences overall were found among the educational experiences (P = .005), with research and fund raising considered the least important. Conclusions. Medical students felt strongly about including nutrition, physical activity, behavior change, personal health, and stress resiliency as part of a LM fellowship curriculum. There was significantly less interest in smoking cessation. Desired experiences of students focused on delivery of LM.
