World Health Organization (WHO) BMI Classification

According to standard WHO guidelines utilized in nutritional and metabolic assessments:

• Overweight Definition: A Body Mass Index (BMI) equal to or greater than 25 (BMI $\ge$ 25) is defined as overweight.
• Pre-obesity Sub-category: Specifically, a BMI between 25.0 and 29.9 falls into the overweight category.
• Normal Weight Range: The healthy or normal weight range is defined as a BMI between 18.5 and 24.9.
• Obesity Threshold: A BMI of 30.0 or higher defines obesity.

Clinical Considerations from an Acu-Cell Perspective

While the WHO standards provide a generalized statistical baseline, relying strictly on BMI can be misleading for individual health evaluations due to several physiological factors:

• Body Composition Limitations: BMI does not distinguish between muscle mass and body fat. Individuals with high muscle density may have a high BMI without being over-fat.
• Mineral and Electrolyte Balance: Weight fluctuations are frequently influenced by fluid retention or imbalances in key electrolytes (such as sodium, potassium, and magnesium), rather than actual adipose tissue accumulation.
• Metabolic Efficiency: True health assessments require looking beyond height-to-weight ratios to evaluate cellular nutrition, metabolic rate, and specific biochemical deficiencies or toxicities.
