Maintenance calories calculator
An estimate of the calories you burn in a day, with the range most people fall in.
Enter your details and press Calculate. Starting values are examples.
How accurate is this?
It uses the Mifflin-St Jeor equation, the most accurate of the common formulas for resting metabolic rate, multiplied by an activity factor. The activity factor is the weakest part, because people overestimate how active they are and everyday movement varies hugely between people.
The better method is your own data. Log your intake and weight for three to four weeks and your real maintenance falls out of the numbers. That's what PixelPT does.
