How this estimate works
The calculator uses the Mifflin–St Jeor equation to estimate resting energy use, then applies an activity factor. Real energy needs can differ because of body composition, health, training, pregnancy and other factors.
For adults only. This calculator is not designed for pregnancy, breastfeeding, children, eating-disorder recovery or medical nutrition planning. A registered dietitian or clinician can help with individual needs.
