Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Prospective participants who meet the inclusion and exclusion crteria will be referred from Health Promotion Board, Singapore to the clinically supervised weight loss programme.

All prospective participants, with their demographic information detailed, will undergo a baseline assessment of the primary and secondary outcome measures. The outcome measures will be retaken following the completion of the 24-week standardised weight management programme. Subsequently, only prospective participants who have either maintained or have lost weight from their baseline initial assessment will be block-randomised to either the control or treatment group. The randomization sequence will be concealed with opaque envelopes. Study participants will be randomly assigned a specifc allocation number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation
Masking / blinding

Summary
Brief summary
This research study aims to evaluate the effectiveness of telephone counselling in conjunction with a weight management programme on weight loss and compliance. We hypothesize that weekly telephone counselling in addition to a standard weight management programme will result in a greater percentage of weight loss and increase in compliance.
