Shift work eating tips:Whole grain, carbohydrate-based and low-fat foods tend to make us sleepy, which makes them an excellent choice for a meal before bed. Protein-rich foods keep us alert, which makes them a good choice for meals and snacks eaten during an evening or night shift.
1 If you are on the afternoon shift have your main meal at mid-day around noon. 2  If you are on the evening shift, eat your main meal at about 6 pm before you go to work. 3  Have a small meal and healthy snacks during your shift. 4  Eating large meals during the night can cause heartburn, gas, or constipation.
