Intermittent fasting has been all the rage lately and for good reason. It is one of the simplest ways to improve your health, increase longevity and lose weight.

Intermittent fasting is an eating pattern in which you go without food periodically. In this guide, we will cover: – What is intermittent fasting? – How to start intermittent fasting – What to eat and when – How long to fast – The benefits of intermittent fasting

Intermittent fasting (IF) is a dietary strategy that makes fasting easier to stick with, as it’s only a few days a week (and that’s what most people need) rather than months-long fasts. IF has been popular in the fitness community for a few years, blended with pre- and post-workout nutrition and a nutrition and training strategy, but more recently has become more popular in the dieting community.

We eat not just to live, but also because eating is one of our most enjoyable hobbies. We are huge foodies. Who would dare to deprive us of that? 

Fasting, particularly intermittent fasting, is becoming more popular, and it’s becoming difficult to ignore the buzz (IF). 

Many people spoke out in favor of intermittent fasting, while others spoke out against it. Is intermittent fasting robbing us of the pleasure of eating? 

Is it, on the other hand, encouraging people to eat in a more healthy and enjoyable manner? 

Beginners to intermittent fasting sometimes have concerns about whether it will benefit them and whether it will work for them. Is it just another fad diet, or does it have any scientific backing? 

I’ve been doing IF for more than two years. During that time, I experimented with several fasting models. I tried the 72-hour fasting after following the 16:8 diet for a time and turning OMAD (One Meal A Day) into a habit. 

It was all really enjoyable for me. 

I’ve read a lot of study articles and personal testimonials on intermittent fasting since then. Now it’s my time to tell you about everything. 

The 16:8 diet is the most basic kind of intermittent fasting. It’s as easy as that: you fast for 16 hours and then eat for another 8 hours. Jennifer Aniston, who told a UK magazine that she follows the technique religiously, drew a lot of attention to it.

The plan is designed for individuals who are new to intermittent fasting; it is intended to introduce people to fasting and prepare them for more advanced models. Nonetheless, many practitioners have found the 16:8 approach to be enough for their health objectives and have adopted it as a lifestyle.

This essay will take you on an adventure to learn more about intermittent fasting. The following is a list of resources: 

  • 16:8 fasting is a kind of intermittent fasting. 
  • Evidence for why IF makes sense and how science backs up its shown advantages.

16:8 Intermittent Fasting: What Is It?

To put it another way, you “time-restrict” your meals by fasting for 16 hours and then eating inside the 8-hour window. 

You can consume water and other calorie-free beverages like black coffee and tea for 16 hours [more on that later]. You may simply match the plan to your sleeping pattern since those 16 hours include your sleeping period.

After 16 hours, you may finally eat and stop your stomach from growling. There are no limitations. One of the major reasons why dieters frequently resort to the 16/8 plan is because of this. It’s a lot easier to stick to when you don’t have any calorie limits throughout your eating time.

Reason & Science Behind Intermittent Fasting

In today’s society, we are continually taught that a “good” diet consists of three meals each day, and that eating fewer than three meals is hazardous and destructive starvation. 

But, when you think about it, our bodies have evolved to go for hours or even days without eating. Our forefathers did not have the luxury of three meals each day. Three meals a day is an uncommon and unnatural arrangement. 

Humans used to be hunters and gatherers before they discovered how to farm and produce, and both occupations required a lot of time and energy. Hunting and gathering food three times a day was neither practical or viable for them. 

As a result, their bodies have adapted to withstand prolonged hunger. People gave succumbed to their gluttony when food grew more available and food storage became feasible. Our bodies are caught up in the jumble of contemporary existence. 

The digestive system, which developed to store food for later consumption, never has the opportunity to do so. The supply of calories does not come to a halt when one meal is followed by another. We consume more calories than we need. Our bodies continue to gain weight, and we continue to want more food. That’s not natural. 

Fasting is a method to reconnect with our natural state. One of the reasons it is still revered in many religious and cultural contexts is because of this. For millennia, humans have never eaten that much or that often; intermittent fasting allows our bodies to relearn how to eat.

What Is the Process of Fasting?

Glucose (sugar) is the body’s main energy source when it is fed, which triggers insulin production. 

When you fast, your blood sugar levels decrease, and your insulin levels drop as well. This activates “starvation mode,” causing the cells to use their fatty acid reserves [1]. So, what exactly does this imply? The fed-fast cycle pushes your body to burn fat reserves, which is why many research on intermittent fasting have shown weight reduction and fat mass decrease [2].

16:8: Getting Started | 5 Golden Rules

16:8 Fasting | Beginners Guide To Intermittent Fasting

1. There is no [easier] way to begin.

 You’ll have to be angry and hungry at first. Many others may not suffer at all, yet you are changing your lifestyle. You should anticipate that skipping a meal that you have been eating for a long time will be difficult. The good news is that it becomes much easier on the third day. 

2. Adhere to a reasonable timetable 

It is important to create a strategy that suits your lifestyle, since this will make it much easier to keep to. The issue is, which meal should you forego? What sort of person do you consider yourself to be?

The majority of individuals choose their fasting-eating period as follows:

  • Morning Birds: Only eat between 6 a.m. and 2 p.m., foregoing supper. 
  • Breakfast Skippers: From 12 p.m. until 8 p.m., they eat.
  • Night Owls: That’s me, eating after work from 4 p.m. until midnight.

However, if your job or personal schedule is unique, you may alter it whenever you like.

3. A little bit of motivation goes a long way.

Look for the appropriate motivation and direction. Before you begin, share your experience with friends and family, join a social group, and study more about intermittent fasting. Taking on a current challenge may help you break the 3-meal-a-day habit. 

4. Feast, but in moderation 

In theory, you are free to consume anything you want. You should gorge yourself at your mealtime. There are no usual dietary limitations during your feasting window, but you should be mindful that what you eat during this time impacts your fasting and health, as well as your weight-loss objectives. 

Because you’ll be fasting for 7-8 hours (not including sleep), it’s a good idea to consume foods that enhance satiety and help you feel full for longer. Sugary meals and refined carbohydrates are known to increase food cravings in the brain, therefore they should be avoided. 

Here’s a list of foods that will keep you full for a long time:

  • Whole wheat, whole bran, oats, brown rice, and couscous are examples of whole grains.
  • Chicken, meat, eggs, fish, beans, dairy products, chickpeas, lentils, kidney beans, soybeans, and so on are all high in protein.
  • Almonds, walnuts, and peanuts are examples of nuts.
  • Avocado, tofu, flaxseed, sunflower seeds, sesame seeds, soymilk, fatty salmon, and other healthy fats

5. Make your way out of the fasting window by drinking.

This is the most ingenious method I’ve discovered for sustaining extended fasting durations of up to 72 hours. 

You must also perfect your drinking game while fasting. I came to discover these techniques to keep your stomach and mind occupied during the first few days of extended fasting until you get used to it. 

  • Always have something to drink on hand. 
  • Drink at least 2 to 3 liters of water each day. 
  • Sparkling water or a lemon slice and mint may be added to your natural water to make it more interesting. 
  • Tea has been rediscovered. Learn about the many types of (nearly-calorie-free) teas available on the market. 
  • Find out how to improve the flavor of your black coffee using cinnamon, iced coffee, and Himalayan salt. A word of advice: fasting is a great way to cut down on your coffee consumption. So try to limit yourself to no more than two glasses each day.

Intermittent Fasting’s Health Benefits

Fasting for short periods of time has been proven to enhance metabolic and physiological health.

16:8 Fasting | Beginners Guide To Intermittent Fasting

1. Reduces the chance of developing type 2 diabetes.

The 16/8 diet regimen reduced blood sugar levels in rats [3]. 

Intermittent fasting lowers body fat and improves blood sugar levels in people [4]. 

Intermittent fasting is linked to a lower risk of type 2 diabetes because it lowers fat mass and blood sugar levels.

2. Helps to lower blood pressure

Blood pressure was substantially lowered in a recent research including over 1400 people who followed an intermittent fasting diet for over a year. Blood pressure lowering advantages, on the other hand, only persisted as long as intermittent fasting was practiced [5]. 

3. It protects against heart disease.

Increased blood pressure and blood sugar increase the risk of cardiovascular disease; thus, intermittent fasting protects against heart disease by lowering blood pressure [6].

 An experiment on overweight individuals who followed an intermittent fasting diet found that the diet decreased oxidative stress, lowering the risk of cardiovascular disease [7].

4. Regulates the body’s circadian cycle.

The circadian clock is an inherent clock in your body. It is thought that syncing your biological clock would benefit your health.

Intermittent fasting, according to some experts, is advantageous because it aligns with the circadian cycle. Insulin levels, for example, fall later in the day, indicating a circadian decrease. Furthermore, since late-night eating is linked to a greater risk of diabetes, an intermittent fasting diet that optimizes the body’s internal clock would be very advantageous [8,9,10].

Is Intermittent Fasting Effective for Weight Loss?

Intermittent fasting, according to several dieters and research, may aid weight loss and fat mass reduction. Intermittent fasting resulted in higher weight and fat reduction in 51 obese men in a research [2]. 

Intermittent fasting, as previously stated, promotes weight reduction because it encourages the body to rely on fat for energy rather than sugar. 

It also works because individuals are less likely to overeat or binge-eat because of the 8-hour eating window.

And, although intermittent fasting is beneficial to the majority of people, everyone is different, and you won’t know unless you try it. If you’re a healthy adult, there’s no reason not to try it. The worst-case situation is going eight hours without eating. 

Is Intermittent Fasting Right For You?

Unfortunately, this is not the case. While it is completely safe for healthy people to follow the diet, it is not advised if you:

  • Are you expecting a child?
  • Is it safe to breastfeed?
  • Are you taking any medicines that need you to take them with meals or at particular times?
  • Have you ever had an eating disorder?

Diabetes may also be a cause to avoid attempting intermittent fasting, particularly if it is done without medical supervision. Nonetheless, increasing data suggests that intermittent fasting may be used to cure diabetes. In two recent trials, an improved technique of IF was shown to restore insulin resistance in individuals with prediabetes or type 2 diabetes [11].

16:8 Fasting | Beginners Guide To Intermittent Fasting


The most basic form of intermittent fasting is the 16:8 diet, in which you fast for 16 hours and eat for 8 hours. 

In addition to encouraging weight loss and fat loss, intermittent fasting has been linked to a reduction in the risk of obesity, diabetes, and cardiovascular disease. 

For a healthy adult, the 16/8 diet has no serious adverse effects and is simple to follow over time. While it may be difficult to get accustomed to missing meals after being taught that you should never skip a meal, you may benefit from a 16:8 diet. 

While we focused on the 16:8 diet, there are a variety of different methods to practice intermittent fasting, including: 

  • The 5/2 diet is eating normally five days a week and “fasting” two days a week by limiting your calorie intake to 600-500 calories a day, which means you would consume two tiny meals or one meal on those days.
  • The 24-hour fast: once or twice a week, you would fast for 24 hours and then eat normally for the remainder of the week. 
  • Alternate day fasting: This is similar to the previous one in that you would fast for 24 hours every other day. 
  • The OMAD, or The Warrior Diet, is an extreme regimen that requires you to fast for 20 hours and eat for just 4 hours (that is my lifestyle now).
