OBJECTIVES ': 'We conducted a randomized trial among overweight long-distance drivers to study the effects of structured lifestyle counseling on body weight and cardiometabolic risk factors.

'

'

METHODS ': 'Men with waist circumference >100 cm were randomized into a lifestyle counseling (LIFE, N=55) and a reference (REF, N=58) group. The LIFE group participated in monthly counseling on nutrition, physical activity, and sleep for 12 months aiming at 10% weight loss. After 12 months, the REF group participated in 3-month counseling. Assessments took place at 0, 12, and 24 months. Between-group differences in changes were analyzed by generalized linear modeling. Metabolic risk (Z score) was calculated from components of metabolic syndrome.

'

'

RESULTS ': 'The mean body weight change after 12 months was -3.4 kg in LIFE (N=47) and 0.7 kg in REF (N=48) [net difference -4.0 kg, 95% confidence interval (95% CI) -1.9– -6.2]. Six men in LIFE reduced body weight by ≥10%. Changes in waist circumference were -4.7 cm in LIFE and -0.1 cm in REF (net -4.7 cm, 95% CI -6.6– -2.7). Metabolic risk decreased more in the LIFE than REF group (net -1.2 points, 95% CI -0.6– -2.0). After 24 months follow-up, there were no between-group differences in changes in body weight (net -0.5 kg, 95% CI -3.8–2.9) or metabolic risk score (net 0.1 points; 95% CI -0.8–1.0) compared to baseline.

CONCLUSIONS ': 'Weight reduction and decreases in cardiometabolic risk factors were clinically meaningful after 12 months of counseling.
