Abstract: Lifestyle interventions, including meal replacement, are effective in the prevention and treatment of type-2-diabetes and overweight. Since insulin is the key weight regulator, we hypothesised that addition of meal replacement to a lifestyle intervention reduces insulin levels more effective than lifestyle intervention alone. In the international, multicenter randomised-controlled ACOORH-trial (Almased-Concept-against-Overweight-and-Obesity-and-Related-Health-Risk) overweight or obese persons with criteria of metabolic syndrome (n=463) were randomised into two groups. Both groups received nutritional advice focussing on carbohydrate restriction and telemonitoring devices. The intervention group substituted all three main meals/day in week 1, two meals/day in week 2–4, and one meal/day in week 5–26 with a protein-rich, low-glycaemic meal replacement. Data were collected at baseline, after 1, 3, 6 and 12 months. All datasets providing insulin data (n=446) were included in this predefined subanalysis. Significantly stronger reductions of insulin (-3.3±8.7μU/ml vs. -1.6±9.8μU/ml), weight (-6.1±5.kg vs. -3.2±4.6kg) and inflammation markers were observed in the intervention group. Insulin reduction correlated with weight reduction and strongest weight loss (-7.6±4.9kg) was observed in those participants with insulin decrease >2μU/ml. These results underline the potential of meal replacement-based lifestyle interventions in diabetes prevention, and measurement of insulin may serve as an indicator for adherence to carbohydrate restriction.
