Objectives: To investigate obese men's health behaviors and strategies for change. Methods: Qualitative interviews with 36 men (BMI 30 and over). Results: All men felt personally responsible for their weight gain. Sedentary lifestyles, stress, lack of worklife balance and weight-based stigma were all significant causes of weight gain and barriers to weight loss. These factors also contributed to men's unwillingness to seek help for their overweight. Conclusion: Addressing the self-blame and stigma associated with obesity is important in developing strategies to improve the health and well-being of obese men.
