the glycemic index


Good and bad carbs

The Montignac Method gave all foods a value: the glycemic index. The higher the glycemic index, the bigger the effect on blood sugar levels and the worse functioning of the pancreas is. Therefore, products with a glycemic index over 50 are called bad carbohydrates. They cannot be eaten in Phase 1 and exceptionally in Phase 2.
Products with a glycemic index under 50 are good carbs.

Below you will find two tables with the most common products.
