Washington, Oct 5 (ANI): A new study has revealed that there is no convincing evidence that transtheoretical model stages of change (TTM SOC) method, which is frequently used to help obese and overweight people lose weight, is effective.
"The use of TTM SOC only resulted in 2kg or less weight loss, and there was no conclusive evidence that this loss was sustained," said Nik Tuah, at Imperial College London, who led Cochrane systematic review.
The transtheoretical model describes a step-by-step way in which individuals move from unhealthy behaviours to healthy ones.
The model helps clinicians and patients by showing the sorts of benefits that can be expected for each step in the sequence. The five stages of change that the model anticipates are pre-contemplation, contemplation, preparation, action and maintenance.
Leading a team of researchers, Tuah looked for studies that had investigated the effectiveness of TTM SOC.
They identified five appropriate studies involving 1834 people who received an intervention and 2076 people who were placed in control groups.
Drawing all the findings together they found that there was no convincing evidence that the intervention produced any significant sustainable weight loss.
There was, however, some indication that when TTM SOC was combined with exercise and dieting, people's physical activity or eating habits did change a little. (ANI)
