Study Title: Diogenes, A randomised controlled trial comparing the effect of reduced-fat diets varying in glycaemic index (high vs. low) and protein content (high vs. normal) on bodyweight in overweight and obese subjects after an initial weight loss.
DiOGenes is a randomised controlled dietary intervention study in obese/overweight families (adults and children) in 8 different European countries, testing the efficacy and safety of diets differing in Glycaemic Index (GI) and protein content.
The 8 centres are divided into "shop centers" and "instruction centers", that provide different kind of dietary intervention and for a different length(see below):
The 2 Shop Centers (Denmark & The Netherlands):
Dietary periods and clinical examinations:
The 6 Instruction Centers (UK, Crete, Germany, Spain, Bulgaria, Czech Republic)
Dietary periods and clinical examinations:
Note that, during the first 6 month intervention all families from the shop centers are provided all foods free of charge "SUPERMARKET PERIOD", whereas in the "Instruction Centers", the families receive dietary instruction only "Instruction Only".
