How does the weight loss calculator work?
The calculator is based on the scientific principle that approximately 7,700 kcal calorie deficit is needed to lose 1 kg of body fat. Based on your chosen daily deficit, it calculates how many weeks you need to reach your target weight.
The 3 Deficit Levels
- 300 kcal (Slow): ~0.3 kg per week. Minimal muscle loss, sustainable, ideal for beginners.
- 500 kcal (Moderate): ~0.45 kg per week. The gold standard – good progress with low risk.
- 750 kcal (Fast): ~0.68 kg per week. Only recommended with higher body fat percentage.
💡 Tip: Combine your calorie deficit with our Calorie Calculator to know your actual daily needs (TDEE).
