A systematic review 1 including 13 studies with a total of 585 subjects was abstracted in DARE. Weight loss was reported in most of the behaviour modification interventions, especially in those with short follow-up periods. Very low calorie diets (VLCDs, 3 studies) did not show beneficial long-term results.
Comment: The quality of evidence is downgraded by inconsistency (heterogeneity in interventions and outcomes).
