How we worked it out

Updated as you change the numbers.

  1. Weight 77.1 kg, height 177.8 cm, age 35.
  2. Mifflin-St Jeor: 10 × kg + 6.25 × cm − 5 × age + 5 = 1,712 kcal.

Method and assumptions

Mifflin-St Jeor (1990) is the formula most often recommended today. Harris-Benedict is the older formula, here in its 1984 revision. Katch-McArdle uses lean body mass, so it suits people who know their body fat percentage. All are population averages; individuals vary by about 10%.
