Abstract
We organized a 180-day-long body weight reduction program for metabolic syndrome (so called, HALSMA diet program) for 37 male workers (30 to 49 years old) who were diagnosed as metabolic syndrome by the annual health check-up. After 1 year, the intervention group showed a statistically significant improvement for the following items; body weight, BMI, body fat rate, waist circumference, blood pressure, dyslipidemia, liver function, and glucose tolerance. For the comparison of two groups after 1 year, the intervention group showed a statistically significant improvement for body weight, BMI, AST, γ-GPT, FBS, HbA1c, and insulin level. According to our results, it is indicated that self-measurement and periodical brief personal contact provided significant benefit in sustaining weight loss.
