Other methods include the 5:2 diet, where you eat normally for 5 days and limit calories to 500-600 on 2 non-consecutive days, and the alternate-day fasting, where you alternate between days of normal eating and fasting.
Types of Intermittent-Fasting
There are several types of intermittent-fasting, including:
- Time-restricted feeding: This involves eating within a certain time window, typically 8-10 hours a day.
- Alternate-day fasting: This involves alternating between days of normal eating and days of fasting or consuming very few calories.
- Modified fasting: This involves consuming fewer calories on fasting days and a normal diet on non-fasting days.
- Periodic fasting: This involves fasting for multiple days in a row, typically once a month or every few months.
