Conclusion
Greater adherence to the MD in the population between 18 and 30 years of age when compared to the younger and older population. Perception of weight gain was observed in 48.6% of the population, while a slight increase in physical activity has been reported in 38.3% of respondents. In addition, 15.0% of respondents turned to farmers or organic purchasing groups for fruits and vegetables, especially in Northern and Central Italy, where BMI values were lower.

Conclusion
Social isolation did not change the diet and smoking habits, but it did cause a decrease in the level of physical activity. Preventive interventions should also turn restrictive measures into an opportunity to improve lifestyle

Social isolation can affect eating habits and behaviors (eating more, more snacks, increased alcohol consumption (Poland) and weight change). Overweight and obese individuals were more prone to these changes (frequency of consumption: <vegetables, fruits and legumes and >salty foods, meat and dairy products).
