|What is the Glycemic Index?|
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).
