1. What is the Weight Loss Equation?

The weight loss equation estimates how much weight you can lose based on your daily calorie deficit over a period of time. It's based on the principle that 1 kg of body weight is approximately equivalent to 7700 kcal.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( deficit \) — Daily calorie deficit (kcal/day)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — Calories needed to burn 1 kg of fat (kcal/kg)

Explanation: The equation calculates how much weight you can expect to lose by maintaining a consistent calorie deficit over time.

3. Importance of Calorie Deficit

Details: Creating a calorie deficit is fundamental for weight loss. This calculator helps you understand the relationship between your daily deficit and expected weight loss over time.

4. Using the Calculator

Tips: Enter your daily calorie deficit (difference between calories consumed and calories burned) and the number of days you plan to maintain this deficit. For best results, use accurate estimates of your calorie needs.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal really equal to 1 kg of weight loss?
A: This is a general estimate. The exact number can vary slightly based on body composition and other factors.

Q2: Why isn't my actual weight loss matching the calculation?
A: Many factors affect weight loss including water retention, muscle gain, metabolic adaptation, and measurement inaccuracies.

Q3: What's a safe daily calorie deficit?
A: Generally 500-1000 kcal/day deficit is recommended, leading to 0.5-1 kg weight loss per week.

Q4: Does the equation work for weight gain too?
A: Yes, the same principle applies in reverse - calorie surplus leads to weight gain.

Q5: Should I adjust my deficit as I lose weight?
A: Yes, as you lose weight your maintenance calories decrease, so you may need to adjust your intake to maintain the same deficit.
