Right Answer RightAnswer::C
Explanation [[Explanation::Diabetes mellitus type 2 (formerly called non insulin-dependent diabetes (NIDDM), obesity related diabetes, or adult-onset diabetes) is a metabolic disorder that is primarily characterized by insulin resistance.

Diet, exercise, and weight loss can restore insulin sensitivity even when the weight loss is modest. Weight loss can control as much as 25% of cases of type 2 diabetes mellitus without the need for medications, since decreasing the amount of adipose tissue helps to decrease insulin resistance.
Educational Objective: Diet, exercise, and weight loss are the first line in diabetes mellitus treatment.
