When you don’t eat for more than 8 to 10 hours, the body enters into a state of fasting.

At first, the body starts using stored sources of glucose. Later it breaks down body fat to use as the next source of energy. Using your body’s fat stores as an energy source can, in the long run, lead to weight loss.

You have to watch your calorie in and calorie out during a time-restricted feeding period.

The 16/8 plan is also known as The Leangains protocol and was popularized by expert Martin Berkhan.

It involves fasting for 16-hours-a-day and eating in the other eight hours.

For example, if you eat dinner at 8 pm then you have to skip the next day breakfast and eat at 12 noon and 8 pm. 

It doesn’t matter when you start your 8 hour eating period, do whatever works for you. I generally eat from 1 pm to 8 pm so that I can join my family and friends at lunch as well as dinner.

The 8-hour feeding window is unrestricted to the number of meals and the quantity of food you eat. However, it is recommended to take a healthy diet and avoid or minimize the consumption of junk food and empty calories.

As far as the 16/8 Intermittent Fasting method fares of weight loss benefit?

Well, it could work, research shows,  incorporation of regular fasting intervals, and eating under normal daily circadian rhythms (i.e., daytime hours in humans) may be important for maintaining optimal metabolic function.

 

5:2 Intermittent Fasting

5:2 plan is a popular type of IF that includes having a normal diet for 5 days a week and restricting caloric intake for any two days of the week.

This plan is called  “The Fast Diet “ and was popularized by British journalist Michal Mosely.

The goal of the 5:2 method is to reduce the caloric intake of any 2 days of the week to 25% of a person’s daily energy requirements.

For example, If you’re a regular caloric intake for 5 days at 2000 calories per day, then on 2 fasting days you would be consuming 500 calories.

It is recommended for women to eat 500 calories and males to eat 600 calories on fasting days. Also, it is better to eat 2 small meals (250 calories per meal for women and 300 calories for men ).

You can also plan your fasting days to be non-consecutive. For example, You might take a normal diet every day of the week but skip Mondays and Thursdays.

 

Eat-Stop-Eat method

Eat-stop -Eat plan involves  24 hours fast either once or twice a week. 

For example, you may eat dinner at 7 pm and then fast until 7 pm the next day.

This plan was popularized by fitness expert Brad Pilon.

You can plan the 2 day fasting days to be non-consecutive. For example, if you eat daily in a week but skip Monday if fasting once a week or  Monday and Thursday if planning to fast twice a week.  

The downside of this method is that it is quite difficult to follow long term for many people. However, you do not need to plan this method right away. Starting with 14-16 hours and then gradually increase your fasting window from there.

 

Alternate-day fasting

In alternate day fasting, one eats not more than 500Kcal, every other day, and the rest of the days eat a normal diet.

There are different variations of this fasting. Some of the versions allow intaking 500 calories on fasting days while some encourage eating even zero or close to zero calories on fasting days. While some encourage eating even zero or close to zero calories on fasting days.

Studies say that self-reported hunger on fasting days was considerable and did not decrease over time, suggesting that alternate-day fasting may not be a feasible public health intervention.
