1. What is the Weight Loss Calculation?

The weight loss calculation estimates how much weight you can expect to lose per week based on your daily caloric deficit. It's based on the principle that a deficit of 3,500 calories equals approximately 1 pound of fat loss.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• Daily deficit — Your daily calorie intake minus your daily calorie expenditure (kcal/day)
• 7 — Number of days in a week
• 3500 — Estimated calories in one pound of body fat

Explanation: The formula calculates how much weight you'll lose by multiplying your daily deficit by 7 days, then dividing by the calories in a pound of fat.

3. Importance of Caloric Deficit

Details: Maintaining a consistent caloric deficit is the foundation of weight loss. This calculator helps you understand the relationship between your daily deficit and expected weekly weight loss.

4. Using the Calculator

Tips: Enter your daily caloric deficit in kcal/day. This is the difference between the calories you consume and the calories you burn each day.

5. Frequently Asked Questions (FAQ)

Q1: Is the 3500 calories per pound rule exact?
A: While commonly used, it's an estimate. Actual fat loss can vary based on body composition and metabolic factors.

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

Q3: What's a safe daily caloric deficit?
A: Generally 500-1000 kcal/day is recommended, resulting in 1-2 lbs/week weight loss.

Q4: Does the type of calories matter for weight loss?
A: For pure weight loss, calories are primary, but nutrient quality affects health, satiety, and body composition.

Q5: Should I adjust my deficit as I lose weight?
A: Yes, as you lose weight your maintenance calories decrease, so you may need to adjust intake to maintain the same deficit.
