Estimate daily maintenance calories from age, sex, height, weight and activity level.
Uses the Mifflin–St Jeor equation to estimate resting needs, then applies an activity multiplier.
Estimate adult maintenance energy needs using a recognised resting-energy equation and an activity multiplier. Treat the result as a starting range, because individual metabolism and goals differ.
A 30-year-old male at 70 kg and 175 cm with moderate activity has an estimated maintenance need near 2,558 kcal per day. The same inputs can produce a different estimate when sex or activity changes.
A qualified professional can help select a safe intake. Aggressive calorie changes may be inappropriate for some people.
Resting energy covers basic body functions; the multiplier estimates additional daily movement and exercise.
