How to Use the Intermittent Fasting Calculator

The Intermittent Fasting Calculator is simple to use and offers a user-friendly interface. Here’s a step-by-step guide on how to use it effectively:

Select Your Fasting Method:
The first step in using the tool is to select the fasting method that suits your needs. The calculator provides four standard methods of fasting:
- 16:8 Method: Fast for 16 hours and eat within an 8-hour window.
- 18:6 Method: Fast for 18 hours and eat within a 6-hour window.
- 20:4 Method: Fast for 20 hours and eat within a 4-hour window.
- 14:10 Method: Fast for 14 hours and eat within a 10-hour window.
If none of these methods work for you, there’s also a Custom option where you can enter your own fasting hours.
Enter Your Eating Start Time:
Next, you’ll need to specify when you plan to start eating. You can select the time using a convenient time picker.
Input Your Current and Target Weight:
The calculator also asks for your current weight and target weight in pounds. These inputs allow the calculator to estimate how much weight you can lose and provide an estimated timeline to reach your target weight.
Calculate Your Fasting and Eating Windows:
Once you’ve entered all the necessary information, click on the "Calculate" button. The tool will then generate your fasting window, eating window, stop eating time, and the next time you can start eating. It will also calculate how much weight you need to lose and provide an estimated timeline for your weight loss journey.
Reset Your Inputs:
If you want to start over with new values, simply click the “Reset” button to clear all the input fields and begin again.
