1. What is the Weight Loss Prediction Formula?

The weight loss prediction formula calculates estimated weight loss based on daily calorie deficit over a specified period. It uses the scientific principle that 3500 calories equals approximately 1 pound of body weight.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( Loss \) — Predicted weight loss in pounds
• \( Deficit \) — Daily calorie deficit in kcal/day
• \( Days \) — Number of days maintaining the deficit
• 3500 — Calories equivalent to 1 pound of body weight

Explanation: The formula provides an estimate of weight loss based on the total calorie deficit accumulated over time.

3. Importance of Weight Loss Prediction

Details: Accurate weight loss prediction helps set realistic goals, track progress, and maintain motivation during weight management programs.

4. Using the Calculator

Tips: Enter your daily calorie deficit in kcal/day and the number of days you plan to maintain this deficit. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this weight loss prediction?
A: This provides a theoretical estimate. Actual results may vary due to metabolic adaptations, water weight fluctuations, and individual differences.

Q2: What is a healthy daily calorie deficit?
A: A deficit of 500-1000 kcal/day is generally recommended for safe weight loss of 1-2 pounds per week.

Q3: Does the 3500 calorie rule apply to everyone?
A: While it's a good general guideline, individual metabolism, body composition, and other factors can affect the actual calorie-weight relationship.

Q4: Should I use this for long-term weight loss planning?
A: This calculator is best for short to medium-term predictions. For long-term planning, consult with healthcare professionals as metabolic changes occur over time.

Q5: Can I use this for weight gain predictions?
A: Yes, by using a calorie surplus instead of deficit, the same formula can estimate weight gain.
