What is Intermittent Fasting and How is it Done?Less of a diet, more of a healthy lifestyle, intermittent fasting means severely restricting your calorie intake for certain periods of time. Most people looking to lose or maintain their weight find this easier than being on a permanent ‘diet’ where every meal needs to be calorie controlled. The most well known type of intermittent fasting diet is the 5:2 diet. This means that for five days a week you eat normally (this means eating healthily, not eating whatever you fancy!) and on the other two, fasting, days you limit your calorie intake to 500 calories for women and 600 for men. It doesn’t matter which two days you fast but you should aim to have one non-fasting day between them. The recommended calorie intake for a healthy adult is 2,000 calories per day, so by eating only a quarter of that, twice a week, you can expect to lose weight. There are many cookbooks and online resources that can help you work out what 500 calories is. You can choose whether to have three very small meals or two slightly larger meals on your fasting days. The 5:2 diet can also be adapted to the 4:3 diet, with four days of normal healthy eating and three days of severely restricted calories. Another way of intermittently fasting is to follow the 16:8 rule. This means eating within an eight hour window every day, and fasting for 16 hours, usually involving overnight. For example, you could eat a healthy breakfast, lunch and dinner (with no calorie counting) all within the hours of 10am and 6pm and eat nothing outside of these hours.
