Contrary to popular belief, the diet is NOT named after Miami's hot spot, South Beach. It's not so much about trying to look like all those young, rollerblading people. Rather, the diet was created for heart HEALTH.
The diet was designed to outline "good carbohydrates" and "good fats" for cardiology patients. The doctor who created it just happens to live outside of Miami, FL. So, the diet name is more marketing than anything. It's easy to remember, right?
