The diet was developed by cardiologist Arthur Agatston with the main aim of creating a diet that helped individuals lose weight, but at the same time kept their bodies whole and healthy, with a particular concern for the internal organs such as the heart. The diet is therefore low in carbohydrates, but rich in protein and lots of good fats, such as avocado and extra virgin olive oil. The South Beach diet is structured into three phases to allow a person to adjust quickly to the diet and get the best results. The first phase is a bit more restrictive than the other two, and it is the phase where a person is expected to lose more weight in comparison to the other two phases. In this phase a person is not allowed to eat starchy carbohydrates, such as bread or pasta, and they are also restricted from consuming fruits and alcohol. This helps to regulate the body’s sugar levels and cravings.
