Type 1 diabetes is an auto-immune condition: your body’s immune system attacks the cells in your pancreas that produce insulin. The exact cause of this reaction is still unknown, but diet and lifestyle are not factors that determine who gets type 1 diabetes.

As a result, your pancreas produces more and more insulin, and eventually the insulin producing cells wear out and become ineffective. Type 2 diabetes is a combination of low insulin and ineffective insulin.
