A healthy diet including antioxidants and vitamins may be beneficial if you work shifts. Studies on shift workers show that irregular working hours may be directly responsible for increased weight, blood pressure and metabolic syndrome. Poor nutrition habits in conjunction with shift work can lead to oxidative stress. If you work shifts, plan a healthy diet to suit your schedule. For optimal energy levels spread your intake of food over 5-7 meals depending on your timetable. Organize small low glycemic snacks to keep you going through the night. Trying to go without food during a long shift will make your body perceive starvation and this will encourage fat storage.
