Diogenes Study: "diet, obesity and genes"

The Diogenes Study aimed to identify the diet which would be most effective in preventing weight gain and weight regain. The study looked at diets with varying glycaemic index (GI) and protein contect.
 
Participants lost 8% of their original weight over 8 weeks, using low calorie formula's. They were then assigned to one of 5 different diets.
 
Group 1: Low Protein, Low glycemic Index.
Group 2: Low Protein, High glycemic Index.
Group 3: High Protein, Low glycemic Index.
Group 4: High Protein, High glycemic Index.
Group 5: Control Diet, medium protein and medium glycemic index.


Results
As you can see in the graph above, those in the low protein-high GI group (Group 2) showed the poorest results, regaining 1.67kg. The best results were seen in those in the high protein-low GI group (Group 3). Those in Group 3 were consuming 22% protein, 43% carbohydrate and 32% fat.
