HOW TO THINK YOURSELF SLIMMER

THE most exciting approach to weight loss and obesity treatment is retraining the brain to think differently about food, says Dr Rob Andrews, an associate professor of diabetes at the University of Exeter.

A study looking at personalised cognitive behavioural therapy for obesity (CBT-OB) found that patients with obesity lost an average of 15 per cent of their weight after 12 months and had kept it off a year later, reported the journal BioPsychoSocial Medicine in March.

‘CBT-OB can work in two ways — visualisation, where we get the patient to imagine themselves attaining their goal, such as cooking a meal rather than buying ready-made meals, or fitting into their favourite jeans,’ says Dr Andrews. ‘This seems to reduce stress and lead to good outcomes.

‘Or we address specific thoughts, such as a misconception that chocolate makes them happy. We talk through the feelings and give them distraction techniques so they stop responding to these thoughts.

‘Over time, they realise they can manage their weight and it adjusts the brain circuits that had led to bad eating habits. It is a long-term approach, whereas with many drugs, as soon as you stop taking them you will probably gain weight.’

However, Jane Ogden, a professor in health psychology, is not convinced it is a long-term solution for everyone.

‘While CBT has its place and is effective for some, whether the benefits are sustained over many years is unclear. It should be part of a package of care that can be offered and, if it works, great.

‘But if it doesn’t, be prepared to help them try something else.’
