The goal of this clinical trial is to achieve diabetes type 2 (DM2) remission using intensive lifestyle intervention.
The main questions it aims to answer are:
* Does intensive lifestyle intervention (including Mediterranean diet with a caloric deficit, daily physical activity, increase in stress resilience and group support) lead to DM2 remission (HbA1c\<6.5%, without medications)
* Can intensive lifestyle intervention (including Mediterranean diet with a caloric deficit, daily physical activity, increase in stress resilience and group support) result to weight loss of \>15 kg
* Does intensive lifestyle intervention result in any side effects (secondary outcome)
Researchers will compare intensive lifestyle intervention to the usual clinical care (control group).
Participants in the experimental group will:
* eat Mediterranean diet with a caloric deficit
* perform daily physical activity
* increase their stress resilience with psychosocial support of the group
* enroll weekly in individual and group counseling and workshops for 6 months, following with 1.5 years of follow-up
