About this calculator

Date of your goal weight from daily calorie deficit: kilos to lose, days needed and weekly rate.

About 7700 kcal per kg of body fat — divide the total need by daily deficit.

Safe rate?

0.5–1 kg per week suits most people; faster needs medical supervision.

Plateaus?

Metabolic adaptation slows loss; recalculate with updated weight.
