Weight loss diets work better with WeightWatchers than the NHS

NHS weight loss programmes are more expensive and less effective than WeightWatchers, a study has found.Weight loss diets work better with WeightWatchers than the NHSDiet programmes such as Weight Watchers, Slimming World and Rosemary Conley are cheaper and far more effective than those run by the NHS’s nanny state, according to new research.

Dieters lost more weight and kept it off for longer by joining a slimming club than after having counselling from specially trained staff in GP surgeries or pharmacies, it was found.

Experts said money would be better spent on encouraging people to attend classes run by commercial companies.

The study, Comparison of range of commercial or primary care led weight reduction programmes with minimal intervention control for weight loss in obesity is published online in the British Medical Journal (BMJ), involved 740 obese or overweight men and women recruited from one NHS trust in Birmingham.

They were divided into six groups and attended either Weight Watchers, Slimming World, Rosemary Conley, a group-based NHS programme run by advisers and dieticians called Size Down, one-to-one counselling sessions in GP surgeries, or one-to-one counselling in pharmacies.

Another group was provided with 12 vouchers for free entrance to a local fitness centre.

At 12 weeks, data was available for 658 of the participants and 522 after one year.

All programmes achieved weight loss at 12 weeks – from an average of 1.37kg in the GP group to 4.43kg in the Weight Watchers group.

But the NHS programmes were found to be no better than the people exercising at a local fitness centre at this point.

At the one year mark, all the programmes except the GP and pharmacy groups had resulted in “significant weight loss”.

However, Weight Watchers was the only programme to achieve significantly greater weight loss than the control group – and was the best attended group.

Compared to the NHS programmes, commercially-run ones meant people typically lost an extra 2.3kg.

The authors, from the University of Birmingham, the Nursing and Midwifery Council and NHS South Birmingham concluded: “Commercially provided weight management services are more effective and cheaper than primary care based services led by specially trained staff, which are ineffective.”

A spokesman for the Department of Health said: “Weight management programmes can be very cost-effective and make losing weight easier for some people, but the best way to lose weight will be different for everyone.

“The local NHS must think about which weight management service will work best based on an individual patient’s needs.”

In September, another study conducted in the UK, Germany and Australia showed that a year-long Weight Watchers programme was far more beneficial than helpful doctor’s advice.

That study was published in The Lancet medical journal.
