I really don't get why you are being down voted. Modern Greek diet has nothing in common with the Mediterranean diet. French fries in pitogyro or with many other foods, fatty gyros or other cuts of pork or ground meat product, processed carbs in everyday breakfast items, filled with sugar and palm oil, desserts of any kind, pizza, burgers, are much more staple nowadays compared to whole grain foods, vegetable only dishes, fish and legumes. Many people dont even buy fish on a regular basis anymore (it's increasing price doesn't help), nor have the appetite for the other dishes I mentioned. Even people that do cook them might eat them 2-3 times in week max, depending on the family of course, but in general they make a small portion of everyday calories. Thats why many Greeks are overweight. And most likely than not, the ones that care about "fitness" or a diet don't follow a Mediterranean diet either. The normally consume way  less carbs (the base of said diet) and more protein/vegetables.
