There is little evidence to indicate that a frequently used weight loss method is effective, according to a Cochrane review.
Researchers reviewed five studies, involving around 4,000 patients, which looked at the transtheoretical model stages of change (TTM SOC) technique, which involves a step-by-step approach for patients to move from unhealthy behaviours to healthy ones.
“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 the authors from Imperial College London.
