Health - calorie deficit

What calorie deficit do I need to lose 1.0 kg per week?

Answer
1100
kcal / day deficit
(1 kg × 7700 kcal/kg) ÷ 7 days = 1100 kcal/day
How we got there
  1. 011 kg of body fat ≈ 7700 kcal of stored energy
  2. 02To lose 1 kg/week: 1 × 7700 = 7700 kcal/week deficit
  3. 03Per day: ÷ 7 = 1100 kcal/day below your TDEE
  4. 04For sustainable loss, keep daily deficit ≤ 25% of TDEE.
