All patients obtained comprehensive nutritional counseling from a qualified dietitian in a one-on-one conversation at study entry. Dietary advices were based on the international guidelines for obesity treatment (42). Additionally, patients received recipes and food lists to support adherence to the dietary recommendations. Nutritional intake was analyzed using 3-day food records (Nutri-Science, Freiburg, Germany) at study onset and during the final week of intervention. Caloric and macronutrient intakes as well as alcohol consumption were evaluated using the software Prodi 6 expert (Nutri-Science, Freiburg, Germany). Daily life physical activity was assessed using activity records that were completed concomitantly with the dietary protocols (i.e. 3 days each at study start and during the final intervention week).
