Weight Loss Formula:
From: | To: |
This calculator estimates how much weight you could lose by a specific date (death date) based on your daily caloric deficit. It uses the principle that 7700 kcal deficit equals approximately 1 kg of weight loss.
The calculator uses the weight loss formula:
Where:
Explanation: The formula calculates total caloric deficit over time and converts it to kilograms of weight loss.
Details: Maintaining a consistent caloric deficit is key to weight loss. This calculator helps estimate results based on your planned deficit and timeframe.
Tips: Enter your daily caloric deficit, expected death date, and start date. All values must be valid (deficit > 0, death date after start date).
Q1: Is 7700 kcal really equal to 1 kg weight loss?
A: This is an estimate that varies between individuals based on metabolism and body composition, but it's a widely accepted approximation.
Q2: What's a safe daily caloric deficit?
A: Generally 500-1000 kcal/day deficit is recommended for safe, sustainable weight loss (0.5-1 kg/week).
Q3: Why use death date in this calculation?
A: This provides a dramatic visualization of long-term weight loss potential, though any target date could be used.
Q4: Does this account for metabolic adaptation?
A: No, this is a simple calculation that doesn't account for metabolic changes during weight loss.
Q5: Can I use this for weight gain calculations?
A: Yes, by using a caloric surplus instead of deficit, though the 7700 kcal/kg ratio may vary more for muscle gain.
