1. What is the Weight Loss Formula?

The weight loss formula estimates pounds lost based on daily caloric deficit and 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:

• Deficit — Daily caloric deficit (kcal/day)
• Days — Time period (days)
• 3500 — Calories in 1 pound of fat (kcal/lb)

Explanation: The equation calculates total caloric deficit over time and converts it to pounds of fat lost.

3. Importance of Caloric Deficit

Details: Caloric deficit is the foundation of weight loss. This calculator helps estimate results from sustained deficits over time.

4. Using the Calculator

Tips: Enter your daily caloric deficit (difference between calories consumed and burned) and the time period in days. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is the 3500 kcal/lb rule exact?
A: It's an approximation. Actual weight loss can vary based on body composition and metabolic adaptation.

Q2: Why isn't my weight loss matching the calculation?
A: Water retention, muscle gain, metabolic changes, and inaccurate tracking can affect actual results.

Q3: What's a safe caloric deficit?
A: Generally 500-1000 kcal/day for 1-2 lbs/week loss, but depends on individual factors.

Q4: Does the type of calories matter?
A: For weight loss, calories are primary, but nutrition quality affects health and sustainability.

Q5: Should I recalculate as I lose weight?
A: Yes, as your TDEE decreases with weight loss, you may need to adjust your deficit.
