/4what Is Intermittent Fasting

The ratio of 16:8 is one of the most popular styles of fasting and is also known as intermittent fasting, a sustainable way to burn fat in order to lose weight. There are many diets that often set strict rules and regulations, but 16:8 intermittent fasting is easy to follow and can provide real results with minimal effort. It shows an effective result and can easily fit into anybody’s lifestyle. Intermittent fasting involves eating only during an eight-hour window and fasting for the remaining 16 hours. You can repeat this cycle as frequently as you would like to. Start with once or twice per week to every day, depending on the nutritional needs and personal preferences.

What Benefits Does Intermittent Fasting Offer

Some research suggests that intermittent fasting can help us live longer and lower our risk of various ailments. The primary reason is, fasting allows the body to carry out a process called autophagy. In essence, the body cleans itself of toxins, dead cells, and similar.

Doing so regularly should, in theory, boost our health.

But, its important to point out that most of the research in the area was carried out on animals . How applicable the results are to us is still in question.

Besides this, intermittent fasting is beneficial because it simplifies our day. Instead of worrying about what to eat as soon as you wake up, you have several hours where you dont have to think about food.

Similarly, fasting can help you reduce your caloric intake. By having your daily meals inside a shorter eating window, you get to enjoy fewer but larger and more satisfying meals. As a result, you can feel fuller and more fulfilled while eating fewer calories.

What Makes Intermittent Fasting So Popular? Does It Work Better Than Normal Eating?

Several famous fitness folks played a significant role in intermittent fastings rise in popularity. Most notably, Brad Pilon, Martin Berkhan, and Greg OGallagher.

They did a great job of marketing intermittent fasting as the go-to solution for nutritional complexity and weight loss problems. They also marketed fasting as the best way to remain lean year-round.

Who Should Avoid The : 2 Diet Or Intermittent Fasting Overall

Although intermittent fasting is very safe for healthy, well-nourished people, it does not suit everyone.

Some people should avoid dietary restrictions and fasting completely. These include:

  • Individuals with a history of eating disorders.
  • Individuals who often experience drops in blood sugar levels.
  • Pregnant women, nursing mothers, teenagers, children and individuals with type 1 diabetes.
  • People who are malnourished, underweight or have known nutrient deficiencies.
  • Women who are trying to conceive or have fertility issues.

Furthermore, intermittent fasting may not be as beneficial for some women as it is for men .

Some women have reported that their menstrual period stopped while they were following this type of eating pattern. However, things went back to normal when they returned to a regular diet.

Therefore, women should be careful when starting any form of intermittent fasting, and stop doing it immediately if any adverse effects occur.

Drinks & Coffee For 1: 8 Fasting

During the 16 hours of fasting, youll omit from eating and only drink 0-calorie drinks -this includes drinking black coffee during your fast!

Adding cream to your coffee also adds calories which will break your fast. While it takes some time to get used to drinking black coffee, its doable. This is a time where spending a little bit more on higher-quality coffee that tastes good black is important.

Besides water, there are many 0-calorie drinks you can enjoy during intermittent fasting. Some of my favorites are:

How Does Intermittent Fasting Work

There are several different ways to do intermittent fasting, but they are all based on choosing regular time periods to eat and fast. For instance, you might try eating only during an eight-hour period each day and fast for the remainder. Or you might choose to eat only one meal a day two days a week. There are many different intermittent fasting schedules.

Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat. He refers to this as metabolic switching.

Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours, Mattson says. If someone is eating three meals a day, plus snacks, and theyre not exercising, then every time they eat, theyre running on those calories and not burning their fat stores.

Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.

Examples Of Different Intermittent Fasting Schedules

Intermittent Fasting: Eating Window Rules

If youre considering giving fasting a shot, there are a few different options for working it into your lifestyle.

Daily Intermittent Fasting

Most of the time, I follow the Leangains model of intermittent fasting, which uses a 16hour fast followed by an 8hour eating period. This model of daily intermittent fasting was popularized by Martin Berkhan of, which is where the name originated.

It doesn’t matter when you start your 8hour eating period. You can start at 8am and stop at 4pm. Or you start at 2pm and stop at 10pm. Do whatever works for you. I tend to find that eating around 1pm and 8pm works well because those times allow me to eat lunch and dinner with friends and family. Breakfast is typically a meal that I eat on my own, so skipping it isn’t a big deal.

Because daily intermittent fasting is done every day it becomes very easy to get into the habit of eating on this schedule. Right now, you’re probably eating around the same time every day without thinking about it. Well, with daily intermittent fasting it’s the same thing, you just learn to not eat at certain times, which is remarkably easy.

Weekly Intermittent Fasting

One of the best ways to get started with intermittent fasting is to do it once per week or once per month. The occasional fast has been shown to lead to many of the benefits of fasting we’ve already talked about, so even if you don’t use it to cut down on calories consistently there are still many other health benefits of fasting.

Avoid Taking More Than A 2

Id say its virtually impossible to fast every single day, or for all your meals to be 100% balanced and nutritious. And honestly, that sounds somewhat miserable anyway.

There will be days when you dont feel like it, or days when you just want some pizza. And thats okay! Cheat days are actually super healthy and a great way to reward yourself for all the work youve put in.

What you dont want to do, is allow yourself to get off track for more than a couple days.

Once your body has adjusted to the intermittent fasting regimen its significantly easier to maintain.

The best way to avoid this is by setting more realistic goals.

Fasting for 6 days each week and having 80% of your meals be balanced and nutritious is a more realistic approach, initially. And its going to be so much easier to sustain.

How Does 1: 6 Intermittent Fasting Help With Weight Loss

Jason Fung, MD, a nephrologist and author of The Complete Guide to Fasting, explained that intermittent fasting can help you burn fat by lowering insulin levels.

This is different than the typical method of weight loss suggested by most experts, which is to restrict calories. Dr. Fung said if you reduce your calories from 2,000 to 1,500 a day , the body is forced to reduce its metabolic rate to match. The slower metabolism makes you feel cold, tired, and hungry. Weight loss eventually plateaus, which means you’ll need to eat even less to lose weight, which is not sustainable. This is why Dr. Fung said calorie-restriction diets fail, which was also proven in contestants from weight-loss TV show The Biggest Loser. A major study that looked at former The Biggest Loser contestants found that a period of intense calorie restriction and weight loss had wrecked their metabolisms, leaving them needing much fewer calories to maintain their new weight than before they went on the show. Most of the contestants ended up regaining most, if not all, the weight they had lost on the show.

To find out your target calories, you need to calculate your basal metabolic rate and total energy expenditure . Use this formula to estimate how many calories you should eat a day for weight loss.

How To Get Started


Getting started is simple.

In fact, chances are youve already done many intermittent fasts before. Many people instinctively eat this way, skipping morning or evening meals.

The easiest way to get started is to choose one of the intermittent fasting methods above and give it a go.

However, you dont need to necessarily follow a structured plan.

An alternative is to fast whenever it suits you. Skipping meals from time to time when you dont feel hungry or dont have time to cook can work for some people.

At the end of the day, it doesnt matter which type of fast you choose. The most important thing is to find a method that works best for you and your lifestyle.


The easy way to get started is to choose one of the methods above and give it a go. Stop immediately if you experience any adverse effects.

Rules For Intermittent Fasting

Keto. Paleo. Plant-based. Mediterranean. Macro-counting. When it comes to diets, there are as many different ways to eat as there are foods to eat, and finding the plan that works for you can be challenging. But rather than focus on WHAT you eat, maybe you should try focusing on WHEN you eat. Thats the idea behind and one of the rules for Intermittent Fasting, or IF, as its more commonly known. Less of a diet than a lifestyle, IF works by limiting all calorie consumption to a specific window of time, followed by a period of fasting. According to research done by John Hopkins neuroscientist Mark Mattson, Ph.D., the body will burn through its sugar stores and go into fat-burning mode after several hours without food, a process he refers to as metabolic switching.

While the fat-burning mode is great for shedding those extra pounds, IF has so many more benefits than simply weight loss, especially in women over 50. Things like lower insulin levels, lower blood sugar, reduced risk of some diseases, and even mental clarity may be experienced by those who consistently use the IF method.

Fasting is an incredible tool and a great way to give our digestive system a rest and allow our body to focus on getting rid of inflammation, explains Gabrielle Brick, Holistic Nutrition Specialist, and Executive Coach. When done consistently in a gentle, healthy, balanced way, and when combined with proper nutrient intake, it can help stabilize metabolism.

Intermittent Fasting Rule #: Stop Stressing About What Breaks A Fast And What Doesnt Break A Fast

Does chewing gum break a fast?

What? I dont even know what to say to that question.

You can fine tune as you get closer to that dream physique. Focus on starting your days off by getting shit done. Water, sparkling water, and black coffee will help you get through the morning. When youre ready to go from 6 pack to 8 pack we can apply the advanced tricks.

You dont need any fancy gimmicks to get started tomorrow .

Some people argue the rules for intermittent fasting to lose weight. The use labels like clean fasting and dirty fasting. I tend to disagree with those labels. Dirty fasts allow you to chew bubble gum and to drink bulletproof coffee as long as youre cutting calories back. Clean fast requires you to be more strict.

Our goal will always be progress over perfection.

Can I Eat *anything* During My Fasting Window

Unfortunately, Boules says that consuming any calories your body could convert to energy for fuel means you are not fasting anymore. Period.

So what can you chew on? Well, its not terribly exciting, but feel free to reach for some sugar-free gum or hard candy with sugar alcohols or non-nutritive sweeteners like xylitol, which Boules says dont affect your calorie intake or blood glucose in the way that regular sugar does, so you wont be breaking your fast. .

But if youre finding that youre a raging hunger monster while doing intermittent fasting or just otherwise totally miserable, its okay to quit and try something elsefasting certainly is not for everyone. If you are genuinely physically and emotionally nourished and satisfied confining food to a set number of hours per day, do you, says Boules. If youre not, just understand this is not required to achieve your goal of good health.

Intermittent Fasting Good For Reversing Insulin Resistance And Muscle Building

3 Intermittent Fasting Rules You Should NEVER Break!

You may start intermittent fasting because you want to reverse your insulin resistance. That objective might take you a little longer to achieve, so you could be fasting intermittently for say 5 6 months.

If your objective is to build muscle with intermittent fasting, then it may take you as long as 4 6 months or even longer. With muscle building, you will want to consider adding a workout regime to the fasting.

You also should consider doing your workout routine which must include resistance training towards the last 2 hours of the fasting window to accelerate the process.

In essence, I am saying the workout should be the last activity you do before you resume eating. That has been shown to be very effective.

There is limited research on the 5:2 diet, which is also known as the Fast diet. A involving 107 overweight or obese women found that restricting calories twice weekly and continuous calorie restriction both led to similar weight loss.

The study also found that this diet reduced insulin levels and improved insulin sensitivity among participants.

A small-scale study looked at the effects of this fasting style in 23 overweight women. Over the course of one menstrual cycle, the women lost 4.8 percent of their body weight and 8.0 percent of their total body fat. However, these measurements returned to normal for most of the women after 5 days of normal eating.
