Estimates, not measurements
Our calculators use published equations that predict average results for groups of people. Your own body can differ from the prediction, sometimes by 10% or more. Treat every number as a starting point to test against your own experience, not as a fixed fact.
Talk to a professional first if you
- are pregnant, trying to become pregnant or breastfeeding
- are under 18
- have diabetes, heart disease, kidney or liver disease, a thyroid condition or another chronic illness
- take medication that affects your appetite, weight or blood sugar
- have, or have had, an eating disorder
- are planning to eat fewer than 1,200 calories a day, or to lose more than 2 pounds a week
If eating is causing you distress
If counting calories leaves you anxious, guilty or preoccupied with food, please step away from the numbers and talk to someone you trust or a health professional. In the US, you can call or text 988 to reach the 988 Suicide & Crisis Lifeline at any time if you're in crisis.
No doctor-patient relationship
Using this site doesn't create any professional relationship between you and CalorieBloom or its author. We can't answer personal medical questions by email. Never delay or ignore professional medical advice because of something you read here.
In an emergency
If you think you're having a medical emergency, call 911 or your local emergency number right away.
