Just because blood sugar levels are high in type 2 diabetes it does not mean than sugar consumption is the cause.
In both cases (obesity and diabetes) the primary way in which sugar contributes to increased risk is via increased calories, palatability and tendency to over consume sugary food and drink.
Type 2 diabetes starts with insulin resistance.
Insulin resistance occurs when tissues no longer respond in the same way to insulin resulting in more insulin being required to clear a given amount of blood glucose.
An individual who eats a diet that is high in sugar but is not in an energy surplus is unlikely to develop insulin resistance.
Whereas an individual who consumes a diet low in sugar but consumes more energy than they need will begin to store the excess energy as fat. This becomes problematic when fat stores arise in muscle and liver inducing insulin resistance.
“type 2 diabetes is caused by genetics and lifestyle factors. Being overweight does increase your risk for developing type 2 diabetes, and a diet high in calories from ANY SOURCE contributes to weight gain.” – American Diabetes Association website.

Over consumption of food and not sugar per se increases your risk of developing type 2 diabetes
