Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: The intervention group will receive a convenient body composition measurement and 6-month smart-phone based individualized counselling. Through close collaborations with the experts in nutrition, we can effectively disseminate the knowledge of weight management and control and healthy diet to the middle-aged population.

No specific intervention will be given to the control group except the common anthropometric and body composition measurement.
Primary purpose: PREVENTION

Brief summary: This study proposed an integrated multi-disciplinary approach including a professional and convenient body composition measurement and an immediate counselling after the measurement, followed by 6-month smart-phone based individualized counselling. We believe that this approach will promote healthy eating behaviors and weight management among middle-aged Chinese in Hong Kong.

Detailed description: This is a two-arm, individual level, 6-month randomized controlled trial. The intervention group will receive convenient body composition measurement and 6-month smart-phone based individualized counselling. No specific intervention will be given to the control group except the common anthropometric and body composition measurement. A pretest-posttest evaluation and between-group comparison will be used to test whether the impact/success of the project has been achieved.
