Should the NHS pay for weight-loss schemes?
Debbie Rugg, 22, from Somerset, dropped from a size 20 to a size 12 after being referred by her doctor to a private weight-loss scheme.
A five-year study by Slimming World found more than two thirds of the 35,000 people on a 12-week course lost about a stone during that period.
However, some health groups have criticised the government for using private weight-loss organisations.
GP Rosemary Leonard and Mel Stubbings, from WeightWatchers International, debate whether the NHS should pay for weight-loss schemes.
