At the Institute for Integrative Nutrition, we learned about the practice of "crowding out." Instead of making a lot of huge changes at once and making foods off limits, try slowly adding in healthier options like fruits, vegetables and more water.
The produce and water will start filling you up and you won't have as much room for the unhealthier options. Soon enough, you'll even start craving the good stuff! Plus, putting restrictions on your diet can backfire.
Remember, you're creating a lifestyle change, not a temporary diet change.
