Which group of individuals will not fall into the apparently healthy category?

Individuals with a known metabolic disease do not fall into the apparently healthy category because they have a recognized medical condition that affects their metabolic processes. This can include disorders such as diabetes, thyroid disease, or metabolic syndrome, all of which can have significant implications for overall health, affecting how the body utilizes energy, regulates blood sugar, and maintains other critical functions.

The concept of being "apparently healthy" typically refers to individuals who do not exhibit any overt signs or risk factors for disease. For instance, those with zero primary risk factors are generally considered healthy since they do not have conditions or behaviors that significantly increase their risk for health issues. Similarly, individuals who actively exercise or are asymptomatic (showing no symptoms of illness) generally fall within this healthy spectrum as they maintain a lifestyle that either prevents or manages health issues effectively.
