The type of person who frequents McDonald’s and the type who shops at the farmers’ market exhibit different eating behaviors across the board.

She knows now that she can do almost anything she wants to — as long as she starts small.

You can disrupt a behavior you don’t want by removing the prompt. This isn’t always easy, but removing the prompt is your best first move to stop a behavior from happening. A few years ago I went to the South by Southwest conference in Austin, Texas. I walked into my hotel room and threw my bag on the bed. When I scanned the room, I saw something on the bureau. “Oh nooooo,” I said out loud to absolutely no one. There was an overflowing basket of goodies. Pringles. Blue chips. A giant lollipop. A granola bar. Peanuts. I try to eat healthy foods, but salty snacks are delicious. I knew the goody bin would be a problem for me at the end of every long day. It would serve as a prompt: Eat me! I knew that if the basket sat there I would eventually cave. The blue chips would be the first to go. Then I would eat those peanuts. So I asked myself what I had to do to stop this behavior from happening. Could I demotivate myself? No way, I love salty snacks. Can I make it harder to do? Maybe. I could ask the front desk to raise the price on the snacks or remove them from the room. But that might be slightly awkward. So what I did was remove the prompt. I put the beautiful basket of temptations on the lowest shelf in the TV cabinet and shut the door. I knew the basket was still in the room, but the treats were no longer screaming EAT ME at full volume. By the next morning, I had forgotten about those salty snacks. I’m happy to report that I survived three days in Austin without opening the cabinet again. Notice that my one-time action disrupted the behavior by removing the prompt. If that hadn’t worked, there were other dials I could have adjusted — but prompts are the low-hanging fruit of Behavior Design.
