This diet is based on what people eat in the Mediterranean region, especially on the seaside. What makes this diet plan unique is that it is not about eating certain quantity of carbs or other food groups. It is a balanced diet with a pyramid structure. The lower the foods are at the pyramid, more you can eat of these. For example, fruits, vegetables, whole grain foods, nuts and olive oil and other vegetable oils are the lowest tier.
At the second tier are foods like fish, dairy and poultry which you can eat twice a week in moderation. You can eat meats and sweets but even less than the second tier. You can have a more detailed understanding of the mediterranean diet here.
