Aktiv 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.

Mediterranean Diet Score
Tidsramme: The outcome will be measured based on an internet food frequency questionnaire filled by patients at admission, visit 7 (3 months) and visit 10 (6 months).
|
The questionnaire allows the calculation of a score reflecting the adherence to the mediterranean diet.

Body Mass Index (BMI)
Tidsramme: Weight wil be measured every month: at admission and visit 4 (1 month), 6 (2 months), 7 (3 months), 8 (4 months), 9 (5 months) and 10 (6 months). The height will be measured only at admission.
|
Weight (kg) / (height (m) x height (m))
|
Weight wil be measured every month: at admission and visit 4 (1 month), 6 (2 months), 7 (3 months), 8 (4 months), 9 (5 months) and 10 (6 months). The height will be measured only at admission.

Percentage of body fat
Tidsramme: The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
|
The outcome will be measured using a DEXA-scan
|
The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
|
|
Insulin Sensitivity
Tidsramme: The outcome will be calculated at admission, visit 7 (3 months) and visit 10 (6 months)
|
The outcome will be estimated based on a formula validated for type 1 diabetes subjects.
The formula takes into account waist/hip ratio, glycated hemoglobin and hypertension.
|
The outcome will be calculated at admission, visit 7 (3 months) and visit 10 (6 months)
|
|
Systolic and diastolic Blood pressure
Tidsramme: The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
|
Average of 3 measures (systolic, diastolic and pulse) after a 5 minutes resting period
|
The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
|
|
Lipid profile
Tidsramme: The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
|
A blood test will measure level of total cholesterol, triglycerides and LDL cholesterol.
|
The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
|
|
Glycemic variability
Tidsramme: The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
|
Glycated hemoglobin will be measured with a blood sample.
Hypoglycemia frequency will be measured with a 4-day glycemia journal.
|
The outcome will be measured at admission, visit 7 (3 months) and visit 10 (6 months)
