Low Carb diets work

Figure 1: Impact of popular ‘healthy’ foods on blood glucose

The glycaemic index (GI) ranks the carbohydrate levels of different foods to help predict their effect on blood sugar compared with pure glucose, which has a GI of 100. However, GI does not take account of the density of each carbohydrate in a portion of food — the glycaemic load, which is derived from the GI, is needed for this. The infographic shows the glycaemic load for a typical serving of various foods that are thought of as ‘healthy’, represented as the equivalent in teaspoons of sugar.

Very useful: don't care about the GI, just keep in mind the amount of sugar, you may eat a teaspoon of honey but avoid cereals and products of cereals flour.
