Dieting can also be very antisocial. But what if you could speed up weight loss

You need to plan meals and snacks, and make a big effort to avoid situations that trigger more eating and drinking than you’d planned

Intermittent fasting is the broad name for diets when you fast to some degree on some, but not all, days of the week

This is only 2,000 to 3,000 kilojoules a day. An average person needs around 8,700 kilojoules a day to maintain their current body weight

To lose between one quarter and half a kilogram a week you would need to reduce your energy intake by 2,000 kilojoules a day

In practical terms, this means that you reduce your intake by so much on a couple of days, you do not to be so strict on the other days

Another variation is the 16-hour overnight fast where eating is restricted every day to an eight-hour window, such as 11am to 7pm
