It's really funny actually. In 2016 she had a couple salads and took a picture of every single one. She went to the gym once and took this picture https://www.instagram.com/p/BQ4H56aBN0z/?hl=en   Then one day it turned into pictures of sandwiches and pasta. Then she posted a picture of an "intuitive eating" book and gained what looks like 100 pounds (she was already over 250).  She didn't try very hard and failed so she's trying to place the blame on diet culture and not her own weak will.
