Slimming World is an English weight loss organisation. It was founded in Derbyshire in 1969 by Margaret Miles-Bramwell, who remained its chairperson until her death on 2 February 2025.

Its focus is predominantly weight loss, and supports members to maintain a healthy weight once they reach their target. It operates through a network of 3,500 consultants across the country.

Slimming World offers an eating plan based on food satiety and energy density as well as a group support service called IMAGE Therapy.
