Calorie deficit per day to lose weight

To lose weight, you need to create a calorie deficit, meaning you consume fewer calories than your body burns. A general guideline is:

1 kg (2.2 lbs) of body fat ≈ 7700 kcal

This means that to lose 1 kg of body fat, you need a total calorie deficit of 7700 calories.

Recommended Daily Calorie Deficit for Weight Loss

Weekly Weight LossDaily Calorie Deficit
0.25 kg (0.55 lbs)~275 kcal/day
0.5 kg (1.1 lbs)~550 kcal/day
1 kg (2.2 lbs)~1100 kcal/day

🔹 Safe Weight Loss Rate: 0.5 - 1 kg per week is considered healthy and sustainable.
🔹 Too High Deficit Risks: A deficit greater than 1100 kcal/day can lead to muscle loss, fatigue, and nutrient deficiencies.

How to Create a Calorie Deficit

  1. Reduce calorie intake – Eat smaller portions, avoid high-calorie foods, and opt for whole foods.
  2. Increase physical activity – Exercise helps burn extra calories and maintains muscle mass.
  3. Combine both methods – A mix of diet and exercise leads to sustainable weight loss.

Example Calculation:

  • If you aim to lose 0.5 kg per week, you need a 550 kcal deficit per day.
  • You can achieve this by:
  • Eating 300 kcal less and
  • Burning 250 kcal through exercise (e.g., 30 minutes of brisk walking).
