What is a South Beach Diet?

South Beach Diet

South beach diet has been started in the 1990s by a Miami cardiologist Dr. Arthur Agatston along with dietitian Marie Almon.  They developed a diet focused to improve cardiovascular health, lowering the risk of heart disease.

After obtaining successful outcomes with many patients losing weight with this approach Dr. Agatston published a book in 2003 entitled The South Beach Diet. In this book, Dr. Agatston outlines the principles of his diet and reached thousands of people that wanted to adopt his approach.

One of the distinctive features of this diet is that it allows to eat a specific type of carbohydrates (low glycemic index carbs). Is a modified low-carb diet where the percentage of carbohydrates is about 28 %, while in a regular diet is 45 to 55 %.

Regarding proteins and fats, they are in higher amounts than a regular diet but the fat consumption is focused on healthy fats. This diet aims to healthy eating and is beneficial for people who want to lose weight and for people who want to maintain weight eating in a healthy way.

Part of the success of this diet is due to high satiety levels produced by the intake of low glycemic index carbs. This kind of carbs produces a smaller rise in the blood of glucose and the hormone that process it insulin than the high glycemic index carbs which results in diminish hunger, greater satiety, and better diet compliance.

These low glycemic index carbs are also a big source of fiber. The fiber provided by this carbs contributes to satiety, a proper function of your gastrointestinal system and helps to control blood cholesterol and sugar levels.

Another distinctive feature of The South Beach Diet is that it has three phases of implementation.
