Bright Side decided to do some research on this topic and figure out what intermittent fasting is and how it works. We were really impressed by what we found and are excited to share the information with you.
What is intermittent fasting?
Intermittent fasting is an eating pattern where the period of eating and the period of fasting trade off in shifts. It’s not a diet since it doesn’t change what you eat, but instead, it changes when you eat.
Unlike diets, fasting is very natural for all living things, even human beings. People were fasting thousands of years ago since in the past, food wasn’t always readily available and wasn’t a guaranteed resource. That being the case, our bodies are actually very well adapted to fasting.
And even today, many of the major religions practice fasting in different forms with many people following them and feeling great.
Based on all of this information, we conclude that fasting is less stressful on our bodies than many diets are.
How does it work?
To put it simply, when you eat, your body spends a few hours processing the food you’ve recently consumed, taking all the energy necessary from that food. When you fast for a certain amount of time, your body doesn’t have this source of energy and has nothing to do but use the fat you have stored.
Our bodies’ reaction to eating causes the production of insulin. And the greater our sensitivity to insulin, the more efficiently we use the energy from our food. After a period of fasting we become the most sensitive to insulin. All these changes lead to weight loss and help to build muscles.

6 most popular ways to do intermittent fasting
The 16/8 method:
Your “eating window” lasts 8 hours during the day and the other 16 hours are used as fasting time. During the fasting hours you can only drink water, tea, coffee or other non-caloric beverages. Women are generally recommended to fast for a bit shorter period of 14-15 hours.
When fasting, you can skip breakfast and have your first meal at noon, followed by your last one by 8 pm. Or, if you have your first meal at 9 in the morning, you should stop eating at 5pm. Choose the timing that suits you and your daily schedule best.
Most people find that this way of intermittent fasting is the most effortless, so this eating in this pattern is the most popular.
Once a week you stop eating for 24 hours, from dinner one day to dinner the next. Or you can opt to fast from breakfast to breakfast or lunch to lunch. During the rest of the days of the week you eat normally.
The 5/2 method
Here, you eat normally for 5 days a week and two days a week you only consume 20-25% of your normal daily calorie intake.
Fasting every other day
Everything is obvious here: you’re fasting every other day. That means you either eat nothing on fasting days or a very minimal amount of food not more than 20% of your daily calorie intake.
The warrior diet
If you follow the warrior diet you are supposed to have only one 4-hour eating window at night when you eat just one very big meal. During the day time you are allowed to eat only small amounts of raw fruits and vegetables.
This fasting pattern suits those who can’t follow any of above listed schedules. From time to time you may choose to skip meals or have a whole fasting day when you feel like doing it. It’s all about what fits your lifestyle and schedule best.
Intermittent fasting has already proven its efficiency with many different people and you can see great results after a short time of implementing it. But it’s really important to remember that the quality of food you eat is crucial. Don’t expect to lose weight, gain muscles and improve your health if you don’t give up junk food and sugar-sweetened drinks.
