A viral weight-loss transformation trend on TikTok actually uses stolen videos modified by artificial intelligence to sell an app called Her75.

At least 11 different accounts posted videos showing identical body movements and framing, but with completely different AI-generated faces. These accounts promoted the app through comments, hashtags, or profile descriptions without clearly labeling their content as commercial advertising.

Investigators managed to trace the original clips back to real content creators whose fitness videos were stolen without permission. Experts explained that modern AI tools allow bad actors to quickly perform inexpensive face-swaps and style transfers at a massive scale. Although automated detection software provided mixed results, visual glitches like disappearing hands confirmed the manipulation.

When questioned, the app company didn’t respond, but TikTok subsequently removed the accounts for violating community guidelines regarding misleading content, weight-loss claims, and unlabelled advertisements.

Difficult words: scale (the size, level, or amount of something, especially when it is very large), glitch (a small, temporary technical fault or mistake in a video or software), subsequently (happening or coming after something else has happened).
