Last updated: October 30, 2026

CaloriesTools gives general estimates for information only. It is not medical advice, and it does not replace a conversation with a doctor or registered dietitian.

Estimates, not measurements

The calculators use well-known published formulas, but every body is different. Your real calorie needs, body composition and fluid needs can differ from the results shown, sometimes by a lot. Use the numbers as a starting point, then adjust based on how you feel and how your body responds over several weeks.

Talk to a professional before you act if you

  • are pregnant or breastfeeding
  • are under 18, because these tools are made for adults
  • have diabetes, kidney, heart, liver or thyroid problems, or any other medical condition
  • take medicine that affects your appetite, weight or fluid balance
  • have been told to limit fluids, protein, salt or calories
  • plan to lose or gain weight quickly
  • have a history of disordered eating, or find that counting calories affects how you feel about food

If counting calories or weighing yourself is causing distress, please stop and speak to a health professional or a support service in your country.

BMI has limits

BMI does not measure body fat, muscle or where fat is stored. It can be misleading for athletes, older adults and people of different ethnic backgrounds. It is one screening number, not a diagnosis.

Exercise and safety

Calories burned figures are rough averages. Do not use them to decide how hard to train. If you are new to exercise or have a health condition, check with a doctor before starting a new programme, and stop if you feel pain, dizziness or unusual shortness of breath.

Sources and accuracy

We link to the research behind each calculator and aim to keep the content correct and up to date, but we cannot guarantee that it is free of errors or suitable for your situation. If you find a mistake, please tell us.
