Abstract

INTRODUCTION:

Obesity is a risk factor for type 2 diabetes, hypertension, dyslipidemia and cardiovascular disease. We aimed to analyse the changes of parameters of the metabolic syndrome and to investigate which markers are useful in the prediction of a successful weight loss. Preliminary data of an ongoing study are presented.

METHODS:

18 obese individuals (15 female, 3 male, mean age 50.9 years, mean BMI 36.1) finished a 12 month weight loss program. This weight loss program was based on a hypocaloric diet (50 % carbohydrates, 30 % fat, 20 % protein) and at least 60 min physical activity per week. At baseline, 6 months and 12 months physical examination, indirect calorimetry, bioimpedance analysis were performed and blood was taken for routine laboratory. An oral glucose tolerance test and an euglycemic hyperinsulinemic clamp (n = 13) were carried out at baseline and after 6 months.

RESULTS:

There was a decrease of the BMI (+/- SEM) from 36.1 +/- 1.3 to 33.4 +/- 1.2 after 6 months and 32.8 +/- 1.3 after 12 months. Waist circumference (-8.8 cm), fasting blood glucose (98.0 to 91.2 and 92.5 mg/dl) and HDL cholesterol (47.2 to 64.6 mg/dl after 12 months) improved significantly. Other parameters of the metabolic syndrome (blood pressure, lipids, insulin resistance) and adiponectin improved slightly, but changes failed to be significant. In a linear regression analysis age, insulin resistance (M-value) and adiponectin at baseline were significant and independent predictors of a successful weight loss.

CONCLUSION:

In conclusion, most parameters of the metabolic syndrome improved after successful weight reduction, although changes of most parameters were modest and did not reach statistical significance.
