girth measurements are a reliable method of measuring body composition

True. Girth measurements can be a reliable method for assessing body composition, particularly in evaluating fat distribution and changes in body size. Measurements at specific sites (e.g., waist, hips, arms, and legs) can provide insights into body fat percentage and health risks associated with obesity. However, while girth measurements are useful, they should ideally be combined with other methods such as BMI, skinfold measurements, or advanced techniques like DEXA scans for a more comprehensive assessment of body composition.
