How Long Does It Take to Lose 30 kg at 0.5 kg per Week?

To lose 30 kg at a rate of 0.5 kg per week, it takes 60 weeks (approximately 14 months). This requires a daily calorie deficit of approximately 550 kcal — the amount you burn minus the amount you eat. A deficit of ~7,700 calories is needed to lose 1 kg of body fat. Combining moderate calorie reduction (~330 kcal from food) with regular exercise (~220 kcal burned) is the most sustainable strategy.
