Cognitive-behavioral therapy (CBT) can help with lifestyle changes by addressing negative thought patterns that hinder motivation and self-discipline. CBT encourages individuals to set realistic goals, develop coping strategies, and reframe thoughts related to health and fitness. By fostering a positive mindset, individuals become more equipped to challenge unhealthy behaviors and make sustainable changes. This therapeutic approach also emphasizes self-monitoring and accountability, ultimately enhancing the likelihood of successful lifestyle modifications over time.
