# Association of Body Image, Body Weight and Social Media Use: A Narrative Review of Observational and Experimental Evidence of the Last Decade

## TL;DR

This review explores how social media use affects body image and weight-related issues in adults over the past decade.

## Contribution

The paper provides a narrative review of recent observational and experimental studies on social media's impact on body image and weight.

## Key findings

- Obese individuals, especially women, report higher body dissatisfaction than those with normal weight.
- Exposure to idealized social media images negatively affects immediate body image.
- Weight-related stigma and healthcare approaches need improvement through specialized training.

## Abstract

Background/Objectives: The multifaceted concept of body image (BI) refers to an individual’s attitudes and impressions of their body. Negative BI is associated with a number of harmful health consequences, including obesity, eating disorders, and symptoms of sadness. The contemporary digital era, marked by the dominance of platforms, has brought about a considerable transformation in the landscape of BI issues. This study’s goal is to compile and assess the connections between social media (SM) use, body weight, and BI in adult populations. Methods: This is a narrative review that comprehensively searches across multiple academic databases, such as PubMed, Medline, Scopus, Web of Science, and Google Scholar. Studies that used SM (online blogs, microblogs, content communities, or social networking sites) for engagement (e.g., sharing, commenting, liking) or image-related activities (e.g., viewing, posting, or engaging with images) with healthy adults (aged 18–70 years) of any body mass index (BMI kg/m2) met the inclusion criteria. Included were observational and experimental studies that examined habitual SM use. Only peer-reviewed works published in English between 2015 and 2025 met the search criteria. Results: The currently available findings suggest that obese people are more dissatisfied with their bodies than people of normal weight, and obese women are more dissatisfied with their bodies than their peers of normal weight. Furthermore, experimental studies have demonstrated that immediate BI is adversely affected by acute exposure to idealized social media photographs. Conclusions: Policies should support specialized training that emphasizes a holistic approach to health and puts functionality and health above attractiveness. This training is crucial for dispelling weight-related stigmas and enabling healthcare providers to offer compassionate treatment that supports mental and physical health. Future research must concentrate on internalization and social pressure or reinforcement because these subjects have not gotten as much emphasis in prior studies. Such mechanism research could help better contextualize the role of recently introduced SM items.
