Way back when wearing animal skins was just becoming fashionable, men quickly learned that the best response to the question "Does this bear skin make my butt look fat?" was to quickly stuff a chunk of mastodon meat into your mouth and smile while mumbling unintelligibly.

Normally reducing the thighs, hips, and bottoms is a multi-billion dollar business, at least in the West, but who knew there were parts of England where malnutrition was so endemic that this sort of thing might become popular.

Now scores of online sites are also offering "herbal" versions of the tablets with names like Star Curves, Big Beautiful Butt Formula, and Brand New Booty pills.
