There are several different ways to do intermittent fasting (also known as intermittent energy restriction). They all share the common theme of splitting the day or week into eating and fasting periods.
During the eating period you should eat normally with a focus on enjoying food and opting for more nutritious choices. Drink water during fasting periods to avoid dehydration.
Some of the common fasting schedules that people use are following, but the list is by no-means exhaustive.
- The 16/8 plan involves eating only during an 8-hour period followed by a 16-hour fasting window. So, if the last meal is at 8pm, the next meal isn't until midday the next day. This way of fasting is known as time-restricted eating.
- The 5:2 diet is another form of intermittent fasting. It involves choosing two days each week where only 2000 to 3000 kilojoules are consumed. The other 5 days of the week are spent eating normally.
- The Eat-Stop-Eat method of fasting involves fasting for a full 24 hours one or two days per week.
- Some advocate for extended fasts that may go for several days but these should only be done under medical and/or dietetic supervision.
There are endless variations to fasting. Such as 12/12 (12 hours of fasting followed by a 12-hour eating window). This is the simplest method as it can mean having the last meal at 7pm and then eating again at 7am the next morning.
There is also 14/10 fasting (14 hours fasting followed by a 10-hour eating window). Or even 18/6 or up to 20/4 (20 hours fasting followed by a 4-hour eating window).
Which way of fasting is best? There isn’t a clear answer to this. Many people find the 16/8 method to be the simplest and most sustainable method to stick to.
