1. What is the Weight Loss Time Equation?

The weight loss time equation estimates how long it will take to lose a specific amount of weight based on your daily caloric deficit. It's based on the principle that 1 kg of body fat contains approximately 7,700 kcal.

2. How Does the Calculator Work?

The calculator uses the weight loss time equation:

Where:

• \( Weight\ Loss \) — Desired weight loss in kilograms
• \( 7700 \) — Calories in 1 kg of body fat (approximate)
• \( Daily\ Caloric\ Deficit \) — Calories consumed below maintenance each day

Explanation: The equation calculates how many days are needed to burn the equivalent calories of your desired weight loss at your current deficit rate.

3. Importance of Caloric Deficit

Details: A consistent caloric deficit is the foundation of weight loss. This calculator helps set realistic expectations about the time required to reach your goals.

4. Using the Calculator

Tips: Enter your desired weight loss in kilograms and your daily caloric deficit (difference between calories burned and consumed). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is 7,700 kcal really equal to 1 kg of fat?
A: This is an approximate value. Studies show it ranges between 7,000-7,700 kcal per kg of body fat, depending on individual factors.

Q2: Why isn't my weight loss matching the prediction?
A: Water retention, glycogen stores, and metabolic adaptations can cause variations. The calculation assumes fat loss only.

Q3: Is a larger deficit better for faster results?
A: While larger deficits lead to faster weight loss, very large deficits can cause muscle loss and metabolic slowdown.

Q4: How accurate is this calculation?
A: It provides a theoretical estimate. Individual results may vary based on metabolism, body composition, and adherence.

Q5: Should I adjust my deficit over time?
A: As you lose weight, your maintenance calories decrease, so you may need to adjust your intake or activity to maintain the same deficit.
