Results may be inaccurate for children and teens, pregnant or breastfeeding people, older adults, athletes, people with certain medical conditions or medications, and anyone outside the population a formula was developed in.
Who should consult a professional first
Speak to a healthcare professional before acting on any result if you are pregnant or breastfeeding, under 18, have or have had an eating disorder, have diabetes, heart, kidney or liver disease, take medications affected by diet or weight, or plan to eat fewer than 1,200 (women) or 1,500 (men) calories a day.
