NHS BMI Guidelines
The National Health Service (NHS) uses BMI as a primary screening tool for weight-related health risks across the UK. NHS guidelines follow WHO standards: Underweight (below 18.5), Healthy weight (18.5-24.9), Overweight (25-29.9), and Obese (30+). The NHS provides free BMI checks at GP surgeries and health centres throughout England, Scotland, Wales, and Northern Ireland.
UK Obesity Statistics
According to Public Health England, approximately 64% of adults in the UK are overweight or obese. This represents a significant public health challenge, with obesity-related conditions costing the NHS billions annually. Regional variations exist, with higher rates in some areas of Northern England and Scotland compared to London and the South East.
NHS Weight Loss Support
The NHS offers free weight management programmes including the NHS Weight Loss Plan, a 12-week diet and exercise plan designed by dietitians and fitness experts. Many GP surgeries can refer patients to local weight management services, and the NHS app provides tools for tracking weight, BMI, and health goals.
