According to the study, which included over 85,000 adults, individuals with a Body Mass Index (BMI) below 18.5 were three times more likely to experience early death compared to those with a BMI between 22.5 and 24.9, which is currently classified as the healthy range. In contrast, no significant increase in mortality rates was recorded among those categorized as ‘overweight’ or ‘class 1 obesity’ (BMI between 25 and 35), while the greatest risk remained with those underweight, according to ‘Science Daily.’
Researchers note that medical advancements in managing obesity-related diseases such as diabetes and heart disease have made the safest range between 22.5 and 30, at least in the Danish context. The ‘Body Mass Index’ remains a simplified tool linking weight to height but overlooks essential factors such as fat distribution, muscle mass, diet, lifestyle, and racial and cultural differences, raising controversy about its use in critical health decisions.
The study also indicated that severe underweight might signal underlying diseases like cancer or type 1 diabetes, as illness sometimes results in weight loss before diagnosis. Researchers added that a certain percentage of body fat might be protective in some medical conditions, such as during chemotherapy when patients suffer from appetite loss and taste changes.
