Insulin was discovered 100 years ago by several scientists at the University of Toronto. Prior to the discovery of insulin, people with type 1 diabetes weren't expected to live much longer than a year or two. In their 1921 discovery, Sir Frederick G. Banting, Charles H. Best and JJR Macleod have saved countless lives. Unfortunately, insulin does is not 100% effective for every person that uses it. 

Insulin resistance is a health condition in which your body’s cells become resistant to the effects of the hormone insulin, which acts to regulate the levels of glucose (sugar) in your body. Lifestyle changes such as altering your diet and increasing the amount of exercise you do can often help prevent this condition. However, for some people, it can be a precursor to prediabetes or even Type 2 diabetes. Insulin resistance may not have any symptoms, but it can have some serious health consequences without treatment. We'll help you better understand the basics of this condition, from what to look out for to what you can expect from treatment.
