Check your BMI

Body Mass Index - (BMI) is a handy guide to the healthy weight for your height. It's used by the government and health professionals.

At Slimming World we’ll never tell you what you should weigh or what your personal target weight should be. If you’d like some help in deciding your weight loss goal, though, the Body Mass Index (BMI) is a measure that can be used to find out the healthy weight range for your height. For most adults, an ideal BMI is in the 18.5 to 24.9 range. To find out your current BMI, use our BMI calculator. Note: A BMI guide may not be accurate for people with a high muscle mass, or mums-to-be, and shouldn’t be used for under-16s. The point at which someone’s health is at risk due to their weight also varies between ethnic groups. If you’re aged 11-15, ask for our special Free2Go guide in group – it has BMI charts suitable for your age range.
