Calories to lose weight for a 85 kg man

PeakX · Calorie targets · Updated 2026-11-11

About 2,300 kcal on training days and 2,150 kcal on rest days, with 170 g protein, if you are 26, 172 cm and train 3–5 days a week. Your maintenance is about 2,790 kcal.

How the number is worked out

1. Resting energy (Mifflin-St Jeor): 10 × 85 + 6.25 × 172 − 5 × 26 + 5 = 1,800 kcal.
2. Times 1.55 for moderate activity = 2,790 kcal to stay the same weight.
3. Minus 500 kcal to lose weight, rounded to 50 = 2,300 kcal. Rest days are 150 kcal lower.
4. Protein at 2 g per kg = 170 g. Fat at 25% of calories = 65 g. Carbs fill the rest: 260 g.

By how active you are

By age (moderately active)

Height matters too: every 5 cm taller adds about 31 kcal to resting energy, or about 50 kcal a day at moderate activity.

What to expect

A 500 kcal daily gap is about 0.5 kg of fat a week, so losing 5 kg takes roughly 11 weeks. Expect the scale to jump around by 1 kg from water and salt; judge the trend over 2–3 weeks.

A vegetarian Indian day at this target
