WHO normal BMI: 18.5–24.9. In Zambia, 8.1% of adults are obese and 22.6% are overweight or obese (WHO 2022 Global Health Observatory). Zambia uses the WHO BMI standard. The Ministry of Health Zambia publishes these statistics nationally. Zambia's obesity rate has doubled since 2000, driven by urbanisation in Lusaka and the Copperbelt region. Urban Zambian women have significantly higher obesity rates than rural women.

Frequently Asked Questions
What is the obesity rate in Zambia? ▾
8.1% of adults in Zambia are classified as obese and 22.6% are overweight or obese per WHO 2022 Global Health Observatory data. Zambia's obesity rate has doubled since 2000, driven by urbanisation in Lusaka and the Copperbelt region. Urban Zambian women have significantly higher obesity rates than rural women. The Ministry of Health Zambia monitors these figures through national health and nutrition surveys.
What BMI standard does Zambia use? ▾
Zambia follows the WHO standard (normal 18.5–24.9, overweight 25–29.9, obese ≥30). The Ministry of Health Zambia applies these thresholds in national clinical guidelines and public health campaigns. Unlike parts of Asia which use lower cut-offs, the standard WHO thresholds reflect the original research on European and North American populations.
Is BMI an accurate measure for people in Zambia? ▾
BMI is a widely used population screening tool in Zambia but it has well-known limitations: it does not distinguish between muscle and fat, and cannot capture fat distribution — abdominal (visceral) fat carries higher cardiovascular risk than fat stored in limbs. The Ministry of Health Zambia recommends combining BMI with waist circumference (men: <94 cm, women: <80 cm per WHO) and other clinical indicators for a complete assessment.
