We’ve Known Since the 1930s: Fatty Diets Cause Insulin Resistance

This graph shows the glu­cose tol­er­ance test results of a healthy per­son on a high-fat test diet as opposed to a high-carb diet. Notice that he had low­er, more sta­ble blood sug­ar lev­els after eat­ing a high-carb diet!

Low-carb gurus have been telling peo­ple that insulin resis­tance, which is the under­ly­ing cause of type 2 dia­betes, results from eat­ing too much car­bo­hy­drate. Yet sci­en­tists have known since the 1930s that the prob­lem can be pro­voked by a high-fat diet and reversed by a starchy, low-fat diet. You can read the research for your­self here.

This work was done in the 1930s. How long will it take before the low-carb gurus hear about it?
