About this calculator
The 'Feeding Window' calculator helps determine your daily eating period using the 16:8 intermittent fasting method. This model involves fasting for 16 hours and eating within an 8-hour window. The formula (24 hours minus fasting hours) calculates your meal window automatically.
Example: a 16-hour fast from 6pm to 10am results in an 8-hour eating window from 10am to 6pm. The tool allows customization beyond the standard 16:8 ratio. Ideal for scheduling meals, aligning fasting with daily routines, or experimenting with time-restricted eating.
Use it to plan meals, adjust fasting schedules, or test different timings. Important: consult a healthcare provider before starting, especially with metabolic conditions, pregnancy, or medical treatments. Adapt changes gradually and monitor your body's response.
Frequently asked questions
How does the calculation work?
We subtract fasting hours from 24 hours. Example: 16h fast results in 8h eating window.
Is it safe for everyone?
Not a substitute for medical advice. People with diabetes, pregnant women, or undergoing treatment should consult professionals first.
Can I adjust the fast?
Yes! The tool allows custom schedules like 14:10 or 18:6, depending on your preferences.
Do I need exactly 8h eating?
No. The window can vary (e.g., 7h if fast is 17h). Adjust according to your daily routine.
