11. Insulin Resistance
Too much sugar leads to insulin resistance, which then puts you at risk for type 2 diabetes, metabolic syndrome, and heart disease. When we eat sugar, blood glucose levels rise and our bodies produce insulin to move the available glucose from the blood into the cells that use it for energy.
When we consume too much sugar on a regular basis (and it is very easy to do), the body is forced to make more and more insulin to keep up.
Eventually, our cells become resistant to it, making it impossible for insulin to do the job it needs to do. At that point, your body goes to some extreme measures to try and flush excess glucose from your system.
