Your BMI Might Be Misleading If You're Asian or African
Summary
Carrying extra body fat can significantly increase the risk of heart disease, stroke, and certain types of cancer. Maintaining a healthy body fat percentage may help prevent these serious health conditions.
One common method for assessing whether someone is overweight is through the Body Mass Index (BMI). The formula for BMI is:
\[ \text{BMI} = \frac{\text{Body weight in kg (pounds)}}{\text{Height in meters (feet)}^2} \]
According to the World Health Organization (WHO), a BMI over 25 suggests overweight status, while a BMI over 30 indicates obesity.

While BMI is widely used to determine if someone is overweight, its accuracy has been questioned for individuals of Asian and African descent. The WHO's BMI guidelines primarily stem from studies conducted on Caucasian populations, potentially making them less applicable to other ethnicities.
Research indicates that Asians and Africans often have a higher body fat percentage compared to Caucasians, even if they appear slimmer. This discrepancy poses a hidden risk, as people from these groups might carry excess body fat without realizing it.
As a personal trainer, I've observed that many of my Asian clients, despite not appearing overweight, often have higher body fat ratios. Dr. Mabel Yap, Deputy Director of the Department of Nutrition at Singapore's Ministry of Health, emphasizes the importance of adjusting BMI cut-off points for different ethnic groups due to these variations. For instance, lowering the obesity threshold from a BMI of 30 to 27 in Singapore would double the obesity rate.
Research from the National Institute of Education in Singapore and Wageningen University in the Netherlands supports that body composition varies among ethnic groups, affecting BMI calculations. This finding is further supported by studies from Thailand and Indonesia.
BMI is known to be less accurate for muscular individuals, as muscle weighs more than fat. Similarly, it may not be fully reliable across all ethnic groups. For Asians and Africans, redefining overweight as a BMI above 23 and obesity as above 27 might prove more accurate.
