Study hypothesis
Different nutritional aproaches to obesity might influence a different endothelial function.
Ethics approval
Approval received from the local Ethical Committee of the University of the Studies of Palermo on the 6th June 2007 (ref: 7/07). Ethics approval was not necessary before the first patient was recruited for several reasons:
1. The enrolled subjects are obese people that spontaneously ask a dietetic treatment
for losing weight
2. No drugs are administered
3. Two safe hypocaloric diets that are traditionally employed in the clinical field are compared (the low carbohydrate diet and the Mediterranean diet)
4. Participants are asked for a written informed consent before participation
5. The sudy is performed according to the Helsinki declaration
6. There is no conflict of interest and the study has no external sponsor to the University (Italian Ministery of University and Scientific and Technological Research)
7. No invasive measurements are performed

Primary outcome measures
Short (five to seven days) and middle (two months) modifications of flow mediated dilation.
These will be measured three times:
1. Before starting the diet treatment
2. Five to seven days after starting the diet treatment
3. Two months after starting the diet treatment
Secondary outcome measures
1. Traditional anthropometric, metabolic and cardiovascular risk factors
2. Intra-renal haemodinamic measurements (resistance and pulsatility indexes)
These will be measured three times:
1. Before starting the diet treatment
2. Five to seven days after starting the diet treatment
3. Two months after starting the diet treatment
