What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
FASTING-MIMICKING DIET PROGRAMDietary supplement
Nutritional intervention via fasting-mimicking diet. Patients receiving adjuvant therapy with aromatase inhibitors will be randomized 1:1 into two arms: one intervention, where will receive nutritional counseling and the study diet for 5 days each month for 6 months,and a control one, where they will receive only nutritional counseling.
| Study group | Role | What they receive |
|---|---|---|
| intervention arm | Experimental | intervention arm where will receive nutritional counseling and the study diet for 5 days each month for 6 months Receives: Dietary Supplement: FASTING-MIMICKING DIET PROGRAM |
| control arm | Experimental | control arm where they will receive only nutritional counseling Receives: Dietary Supplement: FASTING-MIMICKING DIET PROGRAM |
What is being measured
The primary outcome is the main question the study is designed to answer.
Fasting-mimicking diet
Determination of number of cycles of short term FMD exposure to a fasting-mimicking diet in reducing total cholesterol levels
Measured: from baseline to the end of treatment at 12 month
