Losing weight is challenging, but for shift workers it can be more difficult. Shift work refers to a work schedule that alternates between day, night, or early morning. Those who work shift work do not have a set work schedule and the schedule can change from week to week. Shift work has been found to be linked to a greater risk of weight gain, type 2 diabetes and cardiovascular disease.  

This research study aims to investigate the effectiveness of 3 diet-based weight loss strategies.  This information will help provide guidance on strategies specifically for shift workers who are overweight or interested in ways to better manage their weight. This study includes a 6-month weight loss phase and a 12-month weight maintenance phase. Participants must take part in both of these phases.

Researchers are inviting adults 25 – 65 years old who are shift workers and have at least four night shifts a fortnight.
