The Calories Burned Fasting Calculator is a specialized tool designed to estimate the number of calories you burn while fasting. This calculator uses a formula to approximate your basal metabolic rate (BMR), which represents the number of calories your body needs to maintain basic physiological functions at rest. Understanding your BMR during fasting periods can help you make informed decisions about your diet and exercise regimen to achieve your health and weight loss goals.
Formula of Calories Burned Fasting Calculator
To calculate your BMR and subsequently estimate the calories burned during fasting, the calculator uses the following formulae:
Men: BMR = 13.397 * weight (kg) + 4.799 * height (cm) - 5.677 * age (years) + 88.362
Women: BMR = 9.247 * weight (kg) + 3.098 * height (cm) - 4.330 * age (years) + 447.593
Adjusted BMR = BMR * Activity Multiplier
Where: Activity Multiplier = 1.2 (for sedentary activity level during fasting)
These equations account for gender differences in metabolism and provide a baseline from which adjustments can be made based on activity level, even during fasting periods.
General Terms and Helpful Calculations
| Activity Level | Age Range | Weight Range (kg) | Height Range (cm) | Estimated BMR (kcal/day) for Men | Estimated BMR (kcal/day) for Women |
|---|---|---|---|---|---|
| Sedentary | 18-30 | 50-70 | 160-180 | 1500-1800 | 1300-1550 |
| Sedentary | 31-50 | 50-70 | 160-180 | 1450-1750 | 1250-1500 |
| Sedentary | 51+ | 50-70 | 160-180 | 1400-1700 | 1200-1450 |
Note: The “Sedentary” activity level reflects minimal physical activity, which is common during fasting periods. The estimated BMR values are based on average calculations using the formulas provided. Individual results may vary based on specific metabolic rates and other factors.
Example of Calories Burned Fasting Calculator
Consider a 30-year-old woman, weighing 70 kg and 170 cm tall, engaging in sedentary activities during her fasting period. Using the formula:
BMR = 9.247 * 70 + 3.098 * 170 - 4.330 * 30 + 447.593 = 1355.961 kcal/day Adjusted
BMR (for fasting) = 1355.961 * 1.2 = 1627.1532 kcal/day
This example illustrates how to calculate the estimated calories burned during a fasting period, aiding users in managing their diet and exercise plans.
Most Common FAQs
A1: Yes, the calculator provides an estimate of your basal metabolic rate (BMR), which is useful for understanding your calorie expenditure even when not fasting.
A2: While the calculator provides a close estimate, individual variations in metabolism, body composition, and other factors can influence actual calorie burn. It’s best used as a guide rather than an exact measure.
A3: Yes, understanding your BMR and calorie expenditure can help you make informed decisions about your calorie intake, especially if you’re aiming for weight loss or maintenance.
