Intermittent fasting is a popular diet tip used by plenty of people across the world. The 5:2 diet, 16:8 diet, alternate-day fasting and the one-meal-a-day diet are all different ways in which people intermittently fast. Each of these options has its own advantages for dieters.

Intermittent fasting is where people alternate between eating and fasting and then eating at specific time periods.
The best part of intermittent fasting is not having to count calories or watch what you eat but only eat in a specific period.
Some people fast for 16 hours a day and then eat during the remaining eight hours.
Others fast for two days a week while eating just 500 or 600 calories during the remaining two days.
A new study found that the fasting periods don’t have to be that long.
Research in Cell Metabolism found that periods of fasting are just as effective as longer periods of fasting.
A research team at the University of Chicago compared 58 adults who had obesity.
The adults were put into three different groups.

Each group followed a different diet for 10 weeks with one eating between 3pm and 7pm which meant they were fasting for 20 hours.
Another group ate between 1pm and 7pm, fasting for 18 hours.
While the other group ate a normal diet with the normal intervals.
The researchers found that those who followed intermittent fasting plans lost around three percent of their body weight.
There was also no difference between the two groups who were using the intermittent fasting methods.
Krista Varady, a professor of nutrition at the University of Illinois and co-author of the study said 18 hours could be enough.
In a statement, she said: “Until we have further studies that directly compare the two diets or seek to study the optimal time for fasting, these results suggest that the six-hour fast might make sense for most people who want to pursue a daily fasting diet.”
Participants could eat whatever they want in their eating windows but had to stick to zero calories drinks or water in between.
The fasting groups ate around 550 calories less than the group that ate at regular intervals.
However, some of the participants said they did experience spells of feeling dizzy, headaches and fatigue when they were fasting.
But after three weeks the symptoms went away.
Most people already “fast” every day, while they sleep.
Intermittent fasting can be as simple as extending that fast a little longer.
A slimmer can do this simply by eating their first meal at noon and their last meal before 8pm.
