1. What is the Weight Loss Formula?

The weight loss formula calculates how much weight you can expect to lose based on your daily calorie deficit and the time period. It's based on the principle that 1 pound of fat equals approximately 3500 calories.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( \text{Daily Deficit} \) — Calories consumed less than expended each day
• \( \text{Days} \) — Duration of the calorie deficit
• \( 3500 \) — Approximate calories in 1 pound of body fat

Explanation: The equation shows that creating a consistent calorie deficit over time leads to predictable weight loss.

3. Importance of Calorie Deficit

Details: A calorie deficit is essential for weight loss. This calculator helps you estimate how different deficit levels and time periods will affect your weight loss progress.

4. Using the Calculator

Tips: Enter your planned daily calorie deficit (typically 300-1000 kcal/day) and the number of days you plan to maintain this deficit. The calculator will estimate your total weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Is the 3500 calorie rule exact?
A: While 3500 calories ≈ 1 pound is a good estimate, individual metabolism and body composition can cause variations.

Q2: What's a safe daily calorie deficit?
A: Generally 300-1000 kcal/day deficit is safe, leading to 0.5-2 lbs/week weight loss.

Q3: Why might actual weight loss differ?
A: Water retention, muscle gain, metabolic adaptation, and measurement errors can affect results.

Q4: Should I create deficit through diet or exercise?
A: Both are effective. Combining diet and exercise is often most sustainable.

Q5: How accurate is this for long-term predictions?
A: Less accurate for long periods as metabolism adapts. Best for 2-12 week estimates.
