Sugar doesn't cause insulin resistance or (type 2) diabetes. Both are a result of being overweight.

Of course, you can get overweight by eating too much sugar, but it's really about not eating too many calories long-term, regardless of the source.

And of course, refined sugar isn't healthy at all and consumption should be kept to a minimum, outside of exercise.

There are many people with type 2 diabetes that are not overweight; and also many people with overweight and even obesity who do not develop type 2 diabetes. The estimate is that around 537 million people have diabetes worldwide, while overweight and obesity is estimated to affect 1.1 billion people.

Carbohydrates do cause insulin resistance and diabetes. India has average BMI of 21,9, yet has very high incidence of diabetes - largely thanks to its carbohydrate-based diet.
