The Water Fast Weight Loss Calculator helps individuals calculate potential weight loss during a water fast. It provides estimates based on personal metabolic rates and the duration of the fast, ensuring that users can plan their fasts with better accuracy and safety.
Formula of Water Fast Weight Loss Calculator
Calculating potential weight loss during a water fast involves understanding several key factors:
- Caloric Deficit: The total number of calories you would have consumed if you were not fasting.
- Calories per Pound: Typically, a pound of body fat equates to approximately 3500 calories.
To estimate your caloric deficit, you first need to calculate your Basal Metabolic Rate (BMR) using the Harris-Benedict equation:
- For men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)
- For women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
Multiply your BMR by the number of days you plan to fast to estimate your total caloric burn. Remember, this is a rough estimate as metabolic rates can decrease during prolonged fasting.
Table of General Terms
| Term | Definition |
|---|---|
| BMR | Basal Metabolic Rate, the number of calories your body needs at rest |
| Caloric Deficit | The difference between calories consumed and burned |
| Water Fasting | A type of fasting where only water is consumed |
Example of Water Fast Weight Loss Calculator
Suppose a 30-year-old female, weighing 70 kg and 170 cm tall, plans a 5-day water fast. Using our formula, her BMR would be approximately 1441.7 calories/day. Over 5 days, she would have a caloric deficit of approximately 7208.5 calories, equating to roughly 2 pounds of weight loss.
Most Common FAQs
Water fasting can be safe if done correctly but consult a healthcare provider before beginning any fast.
The calculator provides an estimate based on general metabolic rates and might vary for each individual.
For a true water fast, no other beverages should be consumed.
