Summary

The study is a year-long health-behaviour intervention in obese, male truck-drivers to lose weight moderately by 10%, using monthly individual counseling. The investigators hypothesize that lifestyle modification (increased physical activity, changes in eating habits, and improved schedule for sleep) through weight loss improves daytime alertness and quality of sleep, reduces daytime sleepiness, and improves cardiovascular risk factors and health-related fitness.
