If you’re already at a healthy BMI, and losing weight would bring you under the BMI level considered to be healthy, we’re unable to offer you membership. You need to be at a BMI of 23 or above to join Slimming World.

You choose your own Personal Achievement Target with Slimming World, however, the lowest target weight we’re able to accept corresponds to a BMI of 20.


Once you choose your target weight, we're here to empower and encourage you to reach your target by helping you understand how to eat lots of delicious, healthy, filling food while still losing weight and by surrounding you with a warm and supportive community of people.
