What is the Glycemic Index?
South Beach Diet 101

The Glycemic Index is the science behind the South Beach Diet. The Glycemic Index, (or GI), ranks foods based on their effect on blood sugar in your body.

Each food on the Glycemic Index receives a "score" according to how much your blood sugar level increases within a few hours of eating it. When following any weight loss diet based on this concept, you'll be choosing from foods that have a low GI rating.

A potato, for example, is very high-GI food (which is potatoes are on the forbidden foods list on The South Beach Diet) and raises blood sugar very quickly after being consumed; berries have a low-GI rating, so they don't have an adverse effect on your blood sugar. (The longer it takes a carbohydrate to "break down" after being consumed, the lower its GI.)

According to glycemicindex.com, Home of the Glycemic Index, following a diet comprised of lower GI foods can offer the following benefits:

  • A less significant rise in blood glucose following meals;
  • Can help you lose weight;
  • Improves insulin sensitivity;
  • Assists in diabetes control;
  • Provide a longer sense of satiety (fullness).
