How the number is worked out

  1. Resting energy (Mifflin-St Jeor): 10 × 107 + 6.25 × 172 − 5 × 26 + 5 = 2,020 kcal.
  2. Times 1.55 for moderate activity = 3,131 kcal to stay the same weight.
  3. Minus 500 kcal to lose weight, rounded to 50 = 2,650 kcal. Rest days are 150 kcal lower.
  4. Protein at 2 g per kg = 215 g. Fat at 25% of calories = 75 g. Carbs fill the rest: 280 g.

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.
