1. What is the Weight Loss Calculation?

This calculator estimates how long it will take to reach your goal weight based on your current weight, target weight, and daily caloric deficit. It uses the principle that 1 pound of body weight equals approximately 3500 calories.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Current weight — Your current body weight in pounds
• Goal weight — Your target body weight in pounds
• Daily deficit — Your daily calorie deficit in kcal/day
• 3500 — Calories needed to burn 1 pound of fat

Explanation: The calculation determines how many days of maintaining your current caloric deficit are needed to reach your goal weight.

3. Importance of Caloric Deficit

Details: A consistent caloric deficit is essential for weight loss. This calculator helps you plan your weight loss journey by estimating the time required based on your deficit.

4. Using the Calculator

Tips: Enter your current weight and goal weight in pounds, and your daily caloric deficit in kcal/day. For accurate results, track your actual calorie intake and expenditure consistently.

5. Frequently Asked Questions (FAQ)

Q1: Is the 3500 kcal per pound rule exact?
A: While widely used, this is an estimate. Actual weight loss can vary based on body composition and metabolic adaptations.

Q2: Why might my actual results differ?
A: Metabolism changes, water retention, muscle gain, and inaccurate calorie tracking can all affect actual results.

Q3: What's a safe daily caloric deficit?
A: Generally 500-1000 kcal/day for 1-2 lbs/week loss. Extreme deficits can be unhealthy and unsustainable.

Q4: Should I adjust my deficit as I lose weight?
A: Yes, as your weight decreases, your maintenance calories decrease too, so you may need to adjust your intake or activity level.

Q5: Does this account for plateaus?
A: No, this is a linear projection. Most people experience plateaus where weight loss temporarily slows or stops.
