1. What is the 3 Month Weight Loss Calculator?

This calculator estimates potential weight loss over 3 months (90 days) based on your daily caloric deficit. It uses the scientifically established relationship between caloric deficit and fat loss.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{deficit} \) — Daily caloric deficit (kcal/day)
• \( 90 \) — Number of days in 3 months
• \( 7700 \) — Calories needed to burn 1 kg of fat

Explanation: The formula calculates total caloric deficit over 90 days and converts it to kilograms of fat based on the energy density of body fat.

3. Importance of Caloric Deficit

Details: Caloric deficit is the cornerstone of weight loss. This calculator helps set realistic expectations and plan dietary strategies for sustainable weight management.

4. Using the Calculator

Tips: Enter your estimated daily caloric deficit. A typical safe deficit ranges from 300-1000 kcal/day depending on your starting weight and activity level.

5. Frequently Asked Questions (FAQ)

Q1: Is the 7700 kcal/kg value accurate for everyone?
A: While 7700 kcal/kg is a widely accepted average, individual variations in metabolism and body composition may cause slight differences.

Q2: Why focus on 3 months?
A: Three months is a meaningful timeframe for measurable, sustainable weight loss without being overly restrictive.

Q3: Does this account for metabolic adaptation?
A: No, this is a simple projection. Actual results may vary as metabolism adjusts to weight loss.

Q4: Can I use this for weight gain calculations?
A: Yes, by entering a caloric surplus instead of deficit, though muscle gain follows different kinetics than fat loss.

Q5: How accurate is this calculator?
A: It provides a theoretical estimate. Individual results depend on factors like adherence, body composition, and activity levels.
