In November 2007, she joined [[Supersized Bombshells]] under the pseudonym Treasure and, according to her own account, "Just relaxed, and started eating anything and everything." Her highest number of calories ingested in a day was 13,000, she says. She immediately began putting on weight, with much of it going to her vast stomach, which stuck out "like a truck driver" and also hung down near her knees at her peak weight. She also developed a very round face and double chin.

In 2011, after splitting with her long-term partner and moving to Akron, Simpson decided to begin dieting in order to reach a target weight of 370 pounds so that she could more easily take care of her children.
