Intermittent fasting (IF) refers to dietary eating patterns that include prolonged eating or not severely restricting calories. There are many different subgroups of intermittent fasting with individual variations in the duration of fasting; For a few hours, for another day.
It has become most popular topic in the science community due to all the good benefits of fitness and health. People are using it reduce their weight to make their life easier.
What is Intermittent fasting (IF)?
The fast or period of voluntary abstinence for food has been going on for ages across the world. Intermittent fasting is relatively new, with the goal of improving health.
Intermittent fasting does not involve restricting food intake for a set period of time and no changes in the actual foods you are eating. Currently, the most common IF protocol is a daily 16-hour fast and fast throughout the day, one or two days a week.
Intermittent fasting can be considered a natural eating pattern that humans have created to implement and it retreats all the way to our Paleolithic hunter-gatherer ancestors.
The current model of the planned program of intermittent fasting can possibly help improve many aspects of health, from body composition to longevity and aging.
Although IF goes contrary to the norms of our culture and normal daily routines, science may point to low meal frequency and more time fasting as an optimal alternative to the normal breakfast, lunch and dinner models.
There are two common myths related to intermittent fasting.
Myth 1 – You must eat 3 meals per day: This “rule” that is common in Western society was not developed on the basis of evidence for better health, but was adopted as a general pattern for settlers And eventually became the norm.
Not only is the 3 Eating-A-Model lacking scientific rationale, recent studies are showing less food and more fasting to be optimal for human health.
A study has shown that a meal with the same amount of daily calories is better for weight loss and body composition than 3 meals per day.
This finding is a basic concept that has been incorporated into intermittent fasting and those doing IF find it best to eat only 1-2 meals per day.
Myth 2 – You need breakfast, it is the most important meal of the day: Many false claims have been made about the absolute necessity of daily breakfast. “Breakfast increases your metabolism” and “The amount of food decreases in the day after breakfast”.
These claims have been refuted and studied over a 16-week period, showing that skipping breakfast did not decrease metabolism and did not increase food intake in the afternoon and night.
While it is still possible to have intermittent fasting protocols while eating breakfast, some people find it easier to eat breakfast late or skip it altogether and this common myth should not get in the way.
Types of intermittent fasting:
Intermittent fasting comes in various forms and each can have a specific set of specific benefits. Each form of intermittent fasting differs in the fast-to-eat ratio.
The benefits and effectiveness of these different protocols can vary on a different basis and it is important to examine which is best for you.
Factors that may affect which one to choose, including health goals, every day routine, and your current health status. The most common types of IF are alternate day fasting, time-restricted eating, and modified fasting.
1. different day
This approach consists of alternating days of absolutely no calories (from food and drink) with free feeding and eating days.
This scheme has been shown to help in weight loss, improve blood cholesterol and fat levels, and improve markers for inflammation in the blood.
The main downfall with this form of intermittent fasting is that it is most difficult to stick due to the reported hunger on fasting days.
2. Modified Faster – 5: 2 Diet
Modified fasting is a protocol with programmed fasting days, but fasting days allow some food to be consumed. 20-25% of normal calories are allowed to be consumed on fasting days; So if you normally consume 2000 calories on regular eating days, then you will be allowed 400-500 calories on fasting days.
The 5: 2 part of this diet shows the ratio of not fasting on fasting days. So on this diet you will eat normally for 5 consecutive days, then fast or restrict calories by 20-25% for 2 consecutive days.
This protocol is great for weight loss, body composition, and may also benefit from regulation of blood sugar, lipids, and inflammation.
Studies have shown that the 5: 2 protocol is effective for weight loss, reducing inflammation in blood markers (3) and showing signs of improvement in insulin resistance. In animal studies, this modified fasting 5: 2 diet decreased fat, decreased appetite hormones.
3. The 16/8 method:
Also called the Leangains protocol, it involves skipping breakfast and restricting your daily eating period to 8 hours, such as 1–9 p.m. Then you fast for 16 hours in between.
16:8 intermittent fasting is a type of time-restricted fasting. It involves consuming foods during an 8-hour window and avoiding food, or fasting, for the remaining 16 hours every day.
Some people believe that this method works by supporting the body’s circadian rhythm, which is its internal clock.
How To DO This?
The easiest way to follow the 16:8 diet is to choose a 16-hour fasting window that includes the time that a person spend on sleeping.
Some experts advise finishing food consumption in the early evening, as metabolism slows down after this time. However, this is not feasible for everyone.
Some people may not be able to consume their evening meal until 7 p.m. or later. Even so, it is best to avoid food for 2–3 hours before bed.
People may choose one of the following 8-hour eating windows:
- 9 a.m. to 5 p.m.
- 10 a.m. to 6 p.m.
- noon to 8 p.m.
Within this timeframe, people can eat their meals and snacks at suitable times. Eating regularly is important to prevent blood sugar peaks and dips and to avoid excessive hunger.
Some people may need to experiment the best eating window and mealtimes for their lifestyle.

4. Eat Stop Eat
This method was popularized by fitness expert Brad Pilon and has been quite popular for a few years.
By fasting from dinner one day to dinner the next day, this amounts to a full 24-hour fast.
For example, if you finish dinner at 7 p.m. Monday and don’t eat until dinner at 7 p.m. the next day, you’ve completed a full 24-hour fast. You can also fast from breakfast to breakfast or lunch to lunch — the end result is the same.
Water, Tea, and other non calorie beverages are allowed during the fast, but no foods are permitted.
5. The Warrior Diet
According to the founder, it is designed to “improve the way of our eat, feel, perform and look” by stressing the body through reduced food intake, thus triggering “survival instincts.”
It should be noted that Warrior Diet is based on his own beliefs and observations — not strictly on science.
People following this diet undereat for 20 hours per day, then consume as much food as desired at night.
During the 20-hour fasting period, dieters are motivated to consume small amounts of dairy products, hard-boiled eggs and raw fruits and vegetables, as well as plenty of non-calorie fluids.
After 20 hours, people can normally binge on any foods they want within a four-hour overeating window.
However, unprocessed, healthy and organic food choices are encouraged.
To get started, dieters are urged to follow an initial three-week plan divided into phases that will be covered in detail later in this article.
If you’re doing this to reduce weight, it’s very important that you eat normally during the eating periods. In other words, you should eat the same amount of food as if you hadn’t been fasting at all.
The potential downside of this method is that a full 24-hour fast may be fairly difficult for many people. However, you don’t need to go all in right away. It’s fine to start with 14–16 hours, then go upward from it.
How to Burn Fat and Build Muscle at the Same Time – Is Intermittent Fasting the Answer?
Fasting, and is a solid solution for fat-loss. But what about those people who are interested in building some muscle? Can fasting be the answer to building muscle and burning fat together?
It has often been said that it is impossible to reduce fat and gain muscle. This is right, but it has really been confirmed. It is more useful to consider what we can do in a slightly longer period. What can we spend to burn fat and other parts of the day?
So how do you go about it? This is where fasting fast becomes interesting. As an example, we envision 16 hours of daily fat, from 8PM to 12PM the next day. The important thing here is nutrition and workout time.
At some point in the morning fasting state you can choose to do a steady state cardio session. This is not necessary, but a pair running at a 45-minute climb can accelerate fat-loss. During this fast, your body fat is used as fuel and you are getting lean.
Now it’s time to start eating, Starting with a protein shake with a piece of fruit works well with this plan. This shake will be your pre-workout meal. After this you need to do your weight-training workout. Once the workout is over, you should get the calories of your days.
The beauty of this approach, known as nutritional time, means that the food you are eating is being used to repair and re build muscles, due to the stimulation provided by your weight-training session. Is and is not being stocked as fat.
WHAT IS THE AVERAGE WEIGHT LOSS PER WEEK ON INTERMITTENT FASTING?
The amount of weight you can lose through intermittent fasting depends on your starting weight, medical condition, type of food that you eat on your non-fasting days, and other factors like your lifestyle, age, and activity level.
For example, if you choose to eat sweet desserts, drinks, and refined, ultra-processed carbs during your non-fasting days, a fast may not help you lose body fat.
However, if you pair intermittent fasting with healthy eating, you can experience good weight loss. It is found that intermittent fasting was effective for weight loss, with a typical loss of seven to eleven pounds over ten weeks. If you weigh roughly 200 pounds, that equals a five percent loss of your total body weight in just ten weeks.
If you lose weight gradually, you’ll be more successful at keeping it off. So, the average weight loss per week with intermittent fasting is safe, effectual, and long-term.
How to get success with Intermittent fasting plan?
It can be challenging to stick to an intermittent fasting program.
The following tips may help people stay on track and maximize the benefits of intermittent fasting:
- Staying hydrated. Drink lots of water and calorie-free drinks, such as herbal teas, in the day.
- Avoiding obsessing over food. Plan plenty of distractions on fasting days to avoid thinking about food, such as catching up on paperwork or going to see a movie.
- Resting and relaxing. Avoid strenuous activities on fasting days, although light physical exercise such as yoga may b e beneficial.
- Making every calorie count. If the chosen plan allows some calories during fasting periods, select nutrient-dense foods that are rich in protein, fiber, and healthful fats. Examples include beans, lentils, eggs, fish, nuts, and avocado.
- Eating high-volume foods. Select filling yet low-calorie foods, which include popcorn, raw vegetables, and fruits with high water content, such as grapes and melon.
- Increasing the taste without the calories. Season meals generously with garlic, herbs, spices, or vinegar. These foods are extremely low in calories yet are full of flavor, which may help to reduce feelings of hunger.
- Choosing nutrient-dense foods after the fasting period. Eating foods that are high in fiber, vitamins, minerals, and other nutrients helps to keep blood sugar levels steady and prevent nutrient deficiencies. A balanced diet will also contribute to weight loss and overall health.
Intermittent Fasting Benefits
Intermittent fasting’s most obvious benefit is weight loss. However, there are many potential benefits beyond this, some of which have been known since ancient times.
The fasting periods were often called ‘cleanses,’ ‘detoxifications’ or ‘purifications,’ but the idea is similar – to abstain from eating food for a certain period of time. People believed that this period of abstinence from food would clear their systems of toxins and rejuvenate them.
It will reduce your hunger. Your hunger is reduced during your non-eating windows. Your body gets used to your eating schedule very quickly. After a week or two of intermittent fasting, you stop being hungry all the time. Even for the better results if you avoid the carb-rich foods, which cause an insulin spike. An insulin spike, in turn, crashes your blood sugar, and then guess what – you feel hungry again.
Insulin sensitivity. It has been shown that intermittent fasting (IF) in humans increases whole-body insulin sensitivity. Which means that you release less insulin after eating, again resulting in less hunger and evenless risk for diabetes.
Increases insulin sensitivity. High insulin sensitivity allows the cells of the body to use blood glucose more effectively, reducing blood sugar.
Reduces insulin resistance. If you have high insulin resistance, the cells do not absorb as much glucose, which might lead to extreme high blood sugar levels.
Increased production of Human Growth Hormone. That means better regeneration, less muscle loss, and more muscle growth.
Less risk for neurological diseases. Less risk for Alzheimer’s, Multiple Sclerosis, and so on.
Productivity. Without the constant rises and crashes in blood sugar, your energy levels remain much more stable throughout the day, keeping you more productive.
