"The Diabetes Code" by Jason Fung is a truth-altering book that makes the case that type 2 diabetes is curable. The majority of medical professionals, nutritionists, and even diabetes specialists believe that type 2 diabetes is a chronic condition that deteriorates with time. It resembles a long prison sentence with no possibility of parole. In his explanation, Jason Fung shows how traditional treatments that use insulin or other drugs to lower blood sugar can actually make the problem worse, leading to big changes in body mass and even heart disease. He says that the only effective way to treat type 2 diabetes is with a healthy diet and intermittent fasting, not with medicine.
