South Beach diet
The South Beach diet, developed by Miami, Florida-area cardiologist Arthur Agatston, emphasizes the consumption of "good carbs" and "good fats." Dr. Agatston developed this diet for his cardiac patients.
Dr. Agatston believes that excess consumption of so-called "bad carbohydrates", such as the rapidly-absorbed carbohydrates found in foods with a high glycemic index, creates an insulin resistance syndrome—an impairment of the hormone insulin's ability to properly process fat or sugar. In addition, he believes along with many physicians that excess consumption of "bad fats", such as saturated fat and trans fat, contributes to an increase in cardiovascular disease. To prevent these two conditions, Agatston's diet minimizes consumption of bad fats and bad carbs and encourages increased consumption of good fats and good carbs.
