The waist-to-hip ratio is a significant indicator of body fat distribution, particularly in males, and serves as a strong predictor of cardiovascular and metabolic diseases. A ratio over 0.90 suggests that an individual may have an excess of visceral fat, which is the fat that wraps around internal organs and is associated with increased health risks. This type of fat is metabolically active and can lead to insulin resistance, hypertension, and inflammation, all of which are risk factors for heart disease and metabolic disorders.

In contrast, while a high BMI can indicate excess weight, it does not specifically account for fat distribution. Similarly, inadequate hydration and low body fat percentage do not directly correlate with an increased risk of these diseases in the context described. Therefore, the waist-to-hip ratio provides a more focused and relevant measure when assessing the risk for cardiovascular and metabolic health issues in males.
