Being skinny but having a high BMI can occur due to various factors, including muscle mass, bone density, and body composition. Muscle is denser and weighs more than fat, so someone with a high muscle mass might weigh more, leading to a higher BMI despite a slender appearance. It’s crucial to remember that BMI isn't always the best measure of health or body composition. Consulting with a healthcare provider for a full assessment is recommended to understand your health better.
