Fact check: How AI is selling you weight loss

At first glance, weight-loss progress videos on TikTok appear to be genuine personal success stories. However, an investigation by DW Fact Check revealed a deceptive pattern: identical bodies and movements are being recycled across multiple accounts, but with different faces digitally swapped in. At least 11 distinct TikTok profiles have been identified pushing users toward an app called Her75 via their bios, comment sections, hashtags, and video descriptions—with several of these misleading clips racking up millions of views. Behind these viral “transformations,” a coordinated operation is clearly at play.
