YouTube Prescribers and Fad Diets: The Risks of Apomediation

What is this article about?

This article explores the phenomenon of apomediation in YouTube videos on weight loss, particularly those promoting fad diets and supplements. According to the research by Castillo-Abdul, Blanco-Herrero, and Romero-Rodríguez, many of these prescribers are non-professional influencers, whose content often lacks scientific rigor and may pose serious public health risks.

What is apomediation?

Apomediation refers to how users bypass traditional expert sources and instead rely on peer content—like YouTube reviews and influencer advice. While this can democratize access to health information, it also opens the door to misinformation and self-medication, especially among users with low media literacy.

Why is this important?

According to the study, the COVID-19 pandemic fueled both sedentary lifestyles and online searches for rapid weight-loss solutions. As a result, YouTube became flooded with videos on miracle diets, often without expert oversight. This trend, driven more by channel traffic than public health, underscores the dangers of unregulated digital health advice.

Main Findings: How Influencers Present Fad Diets

Key Communication Patterns

• Videos often feature a personal tone with the influencer speaking directly to the camera.

• Positive emotional appeals—joy and amazement—are more common than warnings or balanced perspectives.

• Only a minority include scientific information or expert interviews.

Risks and Misinformation

• Few videos address side effects, contraindications, or long-term health impacts.

• Biased and promotional content is common, particularly during January post-holiday diet surges.

• The content sometimes encourages self-medication with supplements that may carry cancer or cardiovascular risks.

Audience Engagement and Misinformation

What drives engagement?

The study shows that balanced information and mention of risks or contraindications are linked to more likes and comments. Surprisingly, dislikes also correlate positively with views and engagement, suggesting that controversy fuels reach.

Differences by Language

• Spanish-language videos receive more interaction (likes, comments, dislikes) than English-language ones.

• Spanish videos also more frequently include warnings, expert mentions, and balanced information.

How is apomediation applied on YouTube?

This article explains that while apomediation may enhance user empowerment, it also enables pseudo-experts to spread potentially harmful advice. The lack of regulation and editorial control over health content on platforms like YouTube necessitates new frameworks for digital literacy and influencer accountability.
