Live result2,151 kcal/day targetBMR 1,743 × activity 1.55 = TDEE 2,701 kcal/day. Goal adjustment -550 kcal/day.

Formula used

BMR = 10W + 6.25H − 5A + S, where S is +5 for male equation and −161 for female equation. TDEE = BMR × activity factor. Daily target = TDEE + weekly kg change × 7,700 ÷ 7.

This is the method behind the answer, so the result can be checked rather than simply trusted.

2,151 kcal/day targetBMR 1,743 × activity 1.55 = TDEE 2,701 kcal/day. Goal adjustment -550 kcal/day.

Inputs

Sex for equation: Male equation
Age: 35 years
Weight: 80 kg
Height: 178 cm
Activity factor: 1.55
Target weight change: -0.5 kg/week

Method

BMR = 10W + 6.25H − 5A + S, where S is +5 for male equation and −161 for female equation. TDEE = BMR × activity factor. Daily target = TDEE + weekly kg change × 7,700 ÷ 7.

An 80 kg, 178 cm, 35-year-old using the male equation has BMR about 1,730 kcal/day. At 1.55 activity, TDEE is about 2,682 kcal/day before goal adjustment.

Assumptions

This is a population estimate, not a medical prescription.
Activity factor is approximate.
Energy balance is simplified using about 7,700 kcal per kg of body mass change.
