This is a study of weight loss intervention for long-haul commercial truck drivers who face unusual challenges to a healthy lifestyle while working. Participants (n=13) will be long-haul commercial truck drivers with a BMI over 30 kg/m2. Due to licensing issues, all interstate truck drivers are required to be at least 21 years old (US DOT, FMCSA), and thus proposed study participants will be at least 21 years old.
