Wishlist Share

About Course

A clear, non-judgemental guide to the measures the NHS uses to check whether weight may be affecting health – body mass index (BMI) and waist-to-height ratio – including their limits, the different BMI thresholds for some ethnic groups, the health risks of carrying excess weight, and the realistic, evidence-based support available. Includes how workplaces can help without stigma.
