He also currently teaches courses in exercise science and nutrition at the University of California, San Diego and San Diego State University. Comana regularly presents and writes on many topics related to exercise, fitness, and nutrition, and has authored or co-authored more than three dozen articles and chapters in various publications. He has master’s degrees in exercise physiology and nutrition, and currently holds certifications from ACE, the American College of Sports Medicine (ACSM), the National Strength and Conditioning Association (NSCA), and the International Society of Sports Nutrition (ISSN).

An effective weight-management program involves a Understanding Behavioral Change multidisciplinary team approach that includes a physician, Transtheoretical Model of Change registered dietitian, exercise physiologist, and behavioral (Stages of Behavioral Change) Stages of Change therapist. Through this team approach, the three critical areas— Processes of Change Decisional Balance behavior and lifestyle modification, nutrition, and physical Self-efficacy activity—can be coordinated. While this approach is ideal, the cost Tracking Progress and of employing a team of healthcare experts, combined with the lack Keeping Records Participation and Activity Logs of third-party reimbursement, creates potential barriers. Hence, Emotional Association With Programming overweight or obese clients may instead opt to seek the services of Strategies for Overcoming Obstacles competent allied health professionals who are experienced in all Barriers to Participation three disciplines and have an established referral network in place. Relapse Prevention The success of a Lifestyle & Weight Management Coach (LWMC) Summary necessitates proven competencies in these areas and the ability to address the individualized needs of clients. The science behind each area is discussed earlier in this book, while the subsequent chapters focus on programming guidelines and strategies.
