Those figures were carved by Mesolithic Caveman-type peoples and circulated all over continental Europe between 40,000 bc to 11,000 bc, stopping right around sedentary agriculture became prominent.
They're small enough to fit in your hand, they made a lot of them, and during this time period the Cro-Magnon phenotype probably still retained a number of African traits like steatopygia, so my personal guess is they were both a personal jerk-bait figurine, but also something used to set personal beauty standards.

A lot of primitive cultures across Africa, Australia, and South East Asia had something called "fat farming" where parents, who could afford it, would send their teenage daughters away to camps where the girls would be fattened up for like 4 years so they were morbidly obese and 'ready' for marriage.
