4. The Story of Squash’d and Kara Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu She receives an email on her smartphone that night asking her about her vegetable consumption. Kara answers the two simple questions and is ready to send the form off in minutes. The email has a link to the leaderboard – Kara’s friend Becca is the current leader in her group because she’s had 4 vegetarian meals and 12 different vegetables in the last two days! This motivates Kara to keep up with her goals. Kara is a Stanford undergraduate trying to change her eating habits for the better. She wants to improve her fitness and lessen her environmental impact by eating more vegetables so she signs up for a new service called Squash’d that two of her friends already use. She receives an HTML email outlining the program: every night a simple email form will be sent to her smartphone asking her for the number of vegetarian meals she ate that day, as well as the number of different vegetables she ate throughout the day. Kara starts off the next day (her first in the program) feeling confident. She seeks out vegetarian meals at her dining hall for breakfast and lunch, eating 7 different kinds of vegetables in the process. Kara is surprised at how easily she can find all of these vegetables at her dining hall now that she’s actively looking for them. After 4 days with Squash’d Kara is the leader in her friend group, boosting her confidence and strengthening the long-neglected habit of actively seeking vegetables for every meal. She’s on her way to a stronger habit, a healthier diet and a better planet.
