This document provides an overview of the South Beach diet, which became popular in the 1990s as a successor to the Atkins diet. The South Beach diet is divided into three phases that gradually reintroduce certain carbohydrates and foods. The first phase is the strictest and aims to quickly start weight loss while developing healthier eating habits. The second phase allows some previously restricted foods and the third phase focuses on maintenance after weight loss goals are met. Overall, the South Beach diet emphasizes eating lean proteins, vegetables, and "good" carbs and fats while limiting "bad" carbs like sugar and refined grains.
