The Study
Cross-sectional analysis of the reliability and engagement metrics of YouTube videos on semaglutide for weight loss
This study looked at 100 popular YouTube videos about a weight-loss drug and checked how well they explained the facts. It found that some videos were better than others, and that videos with more likes or comments weren’t necessarily the most accurate ones. But it didn’t watch what people actually did after watching the videos, so we can’t say the videos changed anyone’s behavior.
