Why are italians and south European not obese?

So, born and raised in Italy and never got why we are so thin. I eat loads of meat and cheese, so I wont say that I have a healthy diet. From my city, Bologna, we fry and cook loads of thing and in general we eat loads of red meat, like more than 1 time a day. All my family and almost all the people that I know are thin or normal, and I am even underweight. I want to know the opinion of foreigners when they come to our country, do you really find the food more healthy?
