How it is calculated
Meal calories = daily calories × its share ÷ 100, with shares adding to 100%. Fasting hours = maghrib - fajr. Eating window = 24 - fasting hours.
Example
Inputs: Daily calories = 2,000 kcal/day, Iftar share = 50 %, Suhoor share = 30 %, Snack share (between meals) = 20 %, Fajr time = 04:30. Result: Iftar calories: 1,000 kcal; Suhoor calories: 600 kcal; Snack calories: 400 kcal.
Limits and caveats
- There is no single official meal split; the default shares are an editable example.
- People with diabetes and pregnant women should ask their doctor about fasting and meal timing.
- Fajr and maghrib times change daily, so enter them from your local timetable.
Questions about this tool
Should I eat fewer calories in Ramadan?
To keep your weight, keep your usual calories spread over the meals. To lose weight, lower the total.
Why is a late suhoor advised?
Eating suhoor close to fajr shortens the real fasting period and keeps you full longer.
What should suhoor include?
Choose slow-digesting foods such as oats, eggs, fava beans and wholegrain bread, with enough water.
