A randomized controlled trial was conducted to assess the efficacy of the Body Project eating disorder prevention program in reducing eating disorder risk factors and symptoms in young Brazilian women. A total of 141 female university students aged 18-30 years old were randomly assigned to one of two conditions: assessment-only condition (n = 78) and Body Project condition (n = 63). Participants completed scales assessing body dissatisfaction, sociocultural influence, disordered eating attitudes and behaviors, eating disorders symptoms, body appreciation, depressive mood and negative affect at baseline, posttest, and at 1- and 6-month follow-ups. Body Project participants showed significantly greater reductions in body dissatisfaction, sociocultural influence, disordered eating, eating disorder symptoms, depressive symptoms, and negative affect, and greater increases in body appreciation (d = .35-.48) compared to assessment-only participants. Most of the effects persisted through 6-month follow-up (d = .35-.74). Results provide evidence that the Body Project is an effective intervention to reduce eating disorder risk factors and eating disorder symptoms among Brazilian young women, and that this intervention is naturally culturally adaptive.

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Self-Discrepancy and Its Effects01:29

Self-Discrepancy and Its Effects

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Regulation of Food Intake01:30

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
