1. What Is Weight Loss By Week Calculation?

The Weight Loss By Week calculation estimates how much weight you can lose based on your weekly caloric deficit. It's based on the principle that a deficit of approximately 7700 kcal equals about 1 kg of weight loss.

2. How Does The Calculator Work?

The calculator uses the following formula:

Where:

• \( deficit\_week \) — Weekly caloric deficit (kcal/week)
• \( 7700 \) — Estimated kcal per kg of body weight

Explanation: The equation converts your weekly calorie deficit into an estimated weight loss in kilograms.

3. Importance Of Caloric Deficit

Details: Understanding your potential weight loss helps set realistic goals and expectations. A sustainable weight loss is typically 0.5-1 kg per week.

4. Using The Calculator

Tips: Enter your total weekly calorie deficit (difference between calories consumed and calories burned). The value must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal really equal to 1 kg?
A: This is an estimate. Actual weight loss can vary based on body composition and other factors.

Q2: Why isn't my actual weight loss matching this calculation?
A: Water retention, muscle gain, metabolic adaptation, and measurement errors can affect results.

Q3: What's a safe weekly calorie deficit?
A: Generally 500-1000 kcal/day deficit (3500-7000 kcal/week) for 0.5-1 kg weekly loss.

Q4: Does the type of calories matter?
A: While calories drive weight loss, nutrient quality affects health, hunger, and sustainability.

Q5: Should I adjust my deficit as I lose weight?
A: Yes, as your body weight decreases, your maintenance calories will also decrease.
