Aktiver Komparator: Mediterranean Diet
Participants will receive nutritional lessons on the principles of the Mediterranean diet.
This type of diet is defined with a carbohydrate intake of 45-55% of total energy intake, 15-20% of proteins, 30-35% of lipids and less than 7% for saturated fat.
Nine sessions with a nutritionist are planned to cover various topics of the diet.
|
Carbohydrate counting will be reviewed, as well as hypoglycemia management.
The 9 following visits will focus on different aspects of each diets: types of fats, meat and alternatives, grain products, milk and alternatives, fruits and vegetables, salt intake, energy density and restaurants.

Placebo-Komparator: Low Fat Diet
Participants will receive nutritional lessons on the principles of the low fat diet.
This type of diet is defined with a carbohydrate intake greater than 45% of total energy intake, 15-20% of proteins, less than 30% of lipids and less than 7% for saturated fat.
