Weekly Weight Loss Formula:
From: | To: |
The weekly weight loss calculation estimates how much weight you can lose based on your calorie deficit. It's based on the principle that 1 kg of body weight is roughly equivalent to 7700 kcal.
The calculator uses the following formula:
Where:
Explanation: The equation converts your weekly calorie deficit into estimated weight loss based on the energy equivalent of body fat.
Details: Understanding your potential weight loss helps set realistic goals and expectations for diet and exercise programs.
Tips: Enter your total weekly calorie deficit (sum of all daily deficits). For accurate results, track your calorie intake and expenditure consistently.
Q1: Is 7700 kcal exactly equal to 1 kg of weight loss?
A: This is an approximation. Actual weight loss may vary based on body composition and metabolic factors.
Q2: Why isn't my actual weight loss matching the calculation?
A: Water retention, muscle gain, metabolic adaptation, and measurement errors can affect actual results.
Q3: What's a healthy weekly weight loss target?
A: Typically 0.5-1 kg per week is considered safe and sustainable for most people.
Q4: Does the type of calories matter for weight loss?
A: While calorie deficit determines weight loss, nutrient quality affects health, satiety, and body composition.
Q5: Can I use this for weight gain calculations?
A: Yes, the same principle applies - calorie surplus would estimate weight gain instead.
