Week 1: Swap your sweets.
This week is dedicated to getting the crap out of the cabinets and substituting it with nuts, fruits and easy-to-grab snacks. "It's about doing that cleanse of your environment and your home jumping into the holidays. When you look at behavior change theory, there are many things that are important. If the only thing in your cupboard is chips, then you'll most likely grab it. But if you have carrots, you might grab that," says Jennifer Christian-Herman, executive director of HealthWorks products & innovation at Kaiser Permanente.
