A study done on overweight nursing professionals working night shift found that night workers tend to eat at irregular times, carb intake was higher on their days off, however carbs were higher later in the hours for both days on and days off. According to this study in sciencedirect.com, night shift workers had a 25% higher risk of being overweight and a 17% higher risk of obesity, and the study concluded this was in part by wake-sleep cycle disturbance. Night shift workers tend to have snacks and meals as a strategy to stay awake.
