The National Institute for Health and Care Excellence (NICE) has issued guidelines for NHS England to send overweight people to slimming classes, aiming at a 3% loss in weight, asย even such a small change will lead to lowerย blood pressure and reduce the risk of type-2 diabetes. The new approach seeksย a lifelong reduction, not what is often termed as โyo-yo dietingโ, with lost weight coming back after the initial success. It is estimated that one in four adults in the UK are obese with a further 42% of men and 32% of women classed as overweight.ย Obesity is costing the NHS ยฃ5.1 billion annually.
