Relationships have a powerful influence in our lives, yet they are often overlooked as a source of support when it comes to making lifestyle changes. Communication is the key to maximizing the support from relationships. An open, honest discussion with family and close friends at the onset of a lifestyle-change program is important. Relationships with individuals who are supportive, anticipate our needs, and are sensitive to our current situation. However, if the relationship is inflexible, demanding, one-sided, or negative, it may hinder progress. A simple cost-benefit analysis will help you assess whether your relationship is meeting your needs.

"Not everyone is comfortable including others in their lifestyle-change efforts, no matter how positive the relationship. People have different preferences when it comes to making changes. Some people like to engage others to work with them, such as family members or close friends, while others prefer to go it alone. Dr. Kelly Brownell of Yale University calls these two different types of individuals social changers and solo changers.
