What is a major risk factor for developing Type 2 diabetes?

A major risk factor for developing Type 2 diabetes is low physical activity. Regular physical activity plays a critical role in maintaining a healthy weight and managing blood glucose levels. When physical activity is minimal, the body can become less sensitive to insulin, leading to higher blood sugar levels over time. This decrease in insulin sensitivity is a primary factor in the development of Type 2 diabetes, as the body's ability to utilize insulin effectively diminishes.

In contrast, the other options do not represent key risk factors in the same way. A high protein diet might have varying effects on health depending on other factors, but it is not a direct risk factor for Type 2 diabetes. Increased insulin production typically occurs in response to rising blood glucose levels rather than being a risk factor itself. Excessive hydration does not have a known direct link to the risk of developing Type 2 diabetes. Therefore, maintaining physical activity levels is crucial for reducing the risk of this metabolic condition.
