The Nutrisystem Diet Plan

What is known today as the Nutrisystem diet began as a protein shake diet in the 1970s before morphing into its present format of a meal delivery service. Pioneered by businessman Henry Katz, the Nutrisystem diet plan is highly structured with an emphasis on food with a low-glycemic score.


The Low-Glycemic Diet Plan

The Low-Glycemic diet is based on the glycaemic index, a measure of how different types of carbohydrates are absorbed in the body and their effects on blood sugar levels. The glycaemic index was first conceptualized by Canadian scholar David Jenkins and rates foods from 0 to 100.
