To avoid blood sugar spikes, eat first fiber, then proteins and fats, and lastly, carbohydrates: pasta and sweets in general.    This video  shows how to use this model. It shows the blood glucose results when you adjust the time at which you eat each of these types of food.

To avoid blood sugar spikes, eat first fiber, then proteins and fats, and lastly, carbohydrates: pasta and sweets in general.

This video shows how to use this model. It shows the blood glucose results when you adjust the time at which you eat each of these types of food.

The video was made by capturing the screen of this computer simulation model, based on System Dynamics, and is intended exclusively to conceptually show in an interactive and dynamic way what happens to blood glucose when the order in which foods are eaten is changed, as described in detail in the book "Glucose Revolution: The Life-Changing Power of Balancing Your Blood Sugar" by Jessie Inchauspé.

In the bottom left corner, click on START STORY to visualize and simulate the model, in three scenarios where the order of carbohydrate intake is changed.

Click here to see how to use this model.

WARNING: This is just a first version model. Perhaps others will come in the future. For this model to be used in real situations, it still requires a lot of improvement and calibration based on concrete data. 

Your comments and criticisms will be most welcome.
