Final answer:
Obesity is a major risk factor for the development of type 2 diabetes. Reduced rates of sarcopenia are not a contributing factor. Physical inactivity and an aging population also contribute to the increased incidence of type 2 diabetes.
Step-by-step explanation:
Obesity is a major risk factor for the development of type 2 diabetes. A study found that obesity is the root cause of 64 percent of cases of type 2 diabetes in men and 77 percent of cases in women. Insulin resistance is a key feature of type 2 diabetes, and excess weight from obesity can lead to insulin resistance and increase the risk of developing the disease. Therefore, rising obesity rates contribute to the increased incidence of type 2 diabetes.
However, reduced rates of sarcopenia, or muscle loss, is not a contributing factor to the increased incidence of type 2 diabetes. Aging population and physical inactivity are also factors that contribute to the increased incidence of type 2 diabetes.
