TDEE Calculator for Nurses, Carers & Shift Workers
Nurses, paramedics, care workers, and shift workers face a double challenge: physically demanding work combined with disrupted sleep and irregular meal times. Both factors affect metabolism. Your TDEE here reflects the high physical activity of the job. Pair this with a consistent eating schedule to counteract the metabolic effects of shift work.
Shift work disrupts your circadian rhythm, which directly affects metabolism and hunger hormones. Night shift workers produce more ghrelin, the hunger hormone, and less leptin, the satiety hormone. This makes overeating almost inevitable without conscious planning. Studies show that shift workers burn 50 to 100 fewer calories per day than day workers doing the same activity, partly because core body temperature drops during night shifts. Meal timing becomes especially important. Eating your largest meal before your shift and lighter meals during it helps maintain energy without the digestive discomfort that heavy overnight eating causes.
- Your TDEE may be 50 to 100 calories lower during night shifts compared to day shifts. Account for this if you're trying to lose weight.
- Eat your main meal before your shift starts and keep overnight meals light. Heavy eating at 3 AM causes more fat storage than the same meal at noon.
- Prioritise sleep quality with blackout curtains and a consistent sleep schedule, even on days off. Poor sleep increases hunger and reduces calorie burn.
- Caffeine is fine early in your shift but avoid it in the last 4 to 5 hours before you plan to sleep. It disrupts sleep quality even if you fall asleep easily.
