I have a theory that it’s quite simple for her to maintain such a perfect weight and body- of course genetics plays a major part, but if you look at her mum, she herself was extremely athletic which you can see in Kaia ‘s broad swimmer-like shoulders. As a nineteen year old I find it extremely easy to maintain a low weight despite eating not the best foods but that is because I simply eat small quantities until I’m satisfied, so I never crave to binge and I walk a shit tonne- around twenty thousand on average a day (steps) without much effort, and I imagine she may walk a lot more being a model and going to castings all day.
