Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study is examining the effect of serial measurements of waist-to-hip ratios combined with motivational text messages to improve weight reduction in workers in Australia.

Participants will require a mobile phone in order to receive weekly reminder text messages for serial measurements over 8 weeks. Participants will be asked to text back their hip/waist ratios on a weekly basis. Messaging software will only track if people respond.

Participants will also receive text messages every 2 days over 8 weeks with informative messages regarding healthy eating, regular exercise and goal setting. We aim to study the effect of regular encouragement on health.
