There Is Also The 24 Hour Fast And The Warrior Diet

We personally do not care for either of these, and while we might not agree 100% with the 5:2 Diet, these are just too extreme.

The 24-hour diet is just what it sounds like, you dont eat for 24 hours. The simplest way to do this is to not eat after dinner and then skip breakfast and lunch. This is not a healthy way of looking at food though, and it limits your social habits as well.

The Warrior diet is about the same thing you fast during the day with only low-calorie options and eat a huge meal at night. We feel like that is what most Americans do anyways we skimp through the day and Reward ourselves with a huge dinner. This is not healthy nor helpful for weight loss.

What Can I Drink And/or Eat While Fasting

There are no foods or drinks restrictions because intermittent fasting isn’t a diet. BUT as a rule of thumb, prioritize healthy whole foods and minimize your processed carb intake whilst fasting.

As for liquids, stick to water, teas, and coffee. Non-calorie drinks like sparkling water are okay, but avoid diet sodas while fasting and other drinks that might spike your insulin.;

Realistic Weight Loss Numbers

If you do intermittent fasting properly, which means that youre also fat adapted and youre metabolically flexible, its not unusual to lose an average of 1.5-2 lbs of fat every week. Some people lose more. So you want to focus on fat loss, not weight loss.

If you give it 12 weeks or three months for example, at 2 lbs of fat loss per week, thats 24 lbs of body fat gone forever. Thats life changing.

If you dont know what losing 25 lbs of fat looks like, heres one of my other students. She lost exactly 25 lbs without exercise because she did everything else right. Thats how effective intermittent fasting can be if you do it properly which means that you prioritize on getting fat adapted and youre metabolically flexible.

The History Of Intermittent Fasting

5 Healing Benefits of Intermittent Fasting

Aside from the natural fasting we all experience while sleeping, fasting has been around throughout human history. It’s perhaps as ancient as human history itself. Think about it: in pre-civilized times, we couldn’t walk to our refrigerators to eat a snack whenever we wanted. Rather, humans had to wait long periods between meals depending on a successful hunt.

Since then, we’ve also seen intermittent fasting as a spiritual or cultural norm.

Many Christians fast during Ash Wednesday and Good Friday. Muslims refrain from eating sunup to sundown during Ramadan for nearly a month. And many Buddhists employ intermittent fasting daily as a means of mental clarification.

In the religious context, refraining from food is a way to purify the body, mind, and spirit. We see the same concept applied in other settings, such as Ayurvedic medicine, as a means of healing. Even in the Western tradition, one of the fathers of western medicine, Paracelsus stated that “fasting is the greatest remedy“. Intermittent fasting isn’t a fad trend — it’s an integral part of human nature.

Metabolic Flexibility The Key

After youve done a proper 21 day reset, the end result should be that youre now metabolically flexible.

Youre now fat adapted and you can easily switch fuel sources from the foods that you eat to your own body fat for energy. Thats when you get into what I like to call accelerated fat loss.

If you dont do a proper reset, and you still follow a standard western diet and you just jump in with intermittent fasting, that is the definition of metabolic inflexibility. And youre not going to see the results youre looking for.

This is where a lot of people find themselves. This is where you hear people say that they got headaches from fasting, they were starving the entire time, they didnt feel good, and they say it didnt work for them.

Yeah, no kidding. I couldve told you that.

Now the people whos taken the proper 21 day primal reset inside the Fat Loss Accelerator have all successfully unregulated their fat burning metabolism. Theyre metabolically flexible and they can easily fast for long periods of time without feeling hungry.

Which means that theyre able to burn more fat. Theyve also all been successful at being able to keep the weight off.

Now, how long will it take for you to start seeing results? It really depends how long you fast for, and how often. I always like to say that the longer you fast, the better.

So if youve been overweight for a long time, that means that youve also been insulin resistant for a long time.

What Is The Keto Diet

The ketogenic diet is a high-fat, very low-carb way of eating.

Carbs are typically reduced to 20 to 50 grams per day, which forces your body to rely on fats instead of glucose for its main energy source .

In the metabolic process known as ketosis, your body breaks down fats to form substances called ketones that serve as an alternate fuel source .

This diet is an effective way to shed pounds, but it has several other benefits as well.

The keto diet has been used for nearly a century to treat epilepsy and also demonstrates promise for other neurological disorders (

8 ).

Whats more, it may reduce blood sugar, improve insulin resistance and lower heart disease risk factors like triglyceride levels .


The ketogenic diet is a very low-carb, high-fat diet linked to potential health benefits, such as weight loss and improved blood sugar control.

If you commit to the ketogenic diet while doing intermittent fasting as well, it could offer the following benefits.

Its best to consult your doctor before changing anything in your diet, or in this case your diet pattern. If youre cleared to fast, its best to start slow and gradually increase how long the fast is and then the frequency.

Its important to listen to your body too. While weve probably all missed a meal or two and inadvertently fasted, it doesnt mean everyone is designed to follow a plan like this.

Weve found the Crescendo fasting matches our natural appetite for the most part. Following the plan really just helps us be mindful of when were eating for comfort or fun versus actual hunger.

Its also important to think about your schedule before you begin and to see where you can fit in fasting with your obligations and workouts.

Figure Out Caloric Needs

How to Start Intermittent Fasting for Beginners

There are no dietary restrictions when fasting, but this does not mean calories do not count.

People who are looking to lose weight need to create a calorie deficit for themselves this means that they consume less energy than they use. People who are looking to gain weight need to consume more calories than they use.

There are many tools available to help a person work out their caloric needs and determine how many calories they need to consume each day to either gain or lose weight. A person could also speak to their healthcare provider or dietitian for guidance on how many calories they need.

A person interested in losing or gaining weight may find it helps to plan what they are going to eat during the day or week.

Meal planning does not need to be overly restrictive. It considers calorie intake and incorporating proper nutrients into the diet.

Meal planning offers many benefits, such as helping a person stick to their calorie count, and ensuring they have the necessary food on hand for cooking recipes, quick meals, and snacks.

Why Might Changing Timing Help

But why does simply changing the timing of our meals to allow for fasting make a difference in our body? An;in-depth review of the science of IF;recently published in;New England Journal of Medicine;sheds some light. Fasting is evolutionarily embedded within our physiology, triggering several essential cellular functions. Flipping the switch from a fed to fasting state does more than help us burn calories and lose weight. The researchers combed through dozens of animal and human studies to explain how simple fasting improves metabolism, lowering blood sugar; lessens inflammation, which improves a range of health issues from arthritic pain to asthma; and even helps clear out toxins and damaged cells, which lowers risk for cancer and enhances brain function. The article is deep, but worth a read!

The Five Stages Of Intermittent Fasting

. In this state, your body starts to break down and burn fat.

Some of this fat is used by the liver to produce ketone bodies . The two main ketones, acetoacetate and -hydroxybutyrate , serve as an alternative energy source for the cells of your ;heart, skeletal muscle, and brain, when glucose isnt readily available. Did you know that your brain uses up some 60% of your glucose when your body is in the resting state? During intermittent fasting, ketone bodies generated by your liver partly replace glucose as fuel for your brain as well as other organs. This ketone usage by your brain is one of the reasons that intermittent fasting is often claimed to promote mental clarity and positive mood ketones produce less inflammatory products as they are being metabolized than does glucose, and they can even kick-start production of the brain growth factor BDNF! Ketones have also been shown to reduce cellular damage and cell death in neurons and can also reduce inflammation in other cell types.;

As their level in your bloodstream rises, ketones can act as signaling molecules, similar to hormones, to tell your body to ramp up stress-busting pathways that reduce inflammation and repair damaged DNA for example.

Within 24 hours, your cells are increasingly recycling old components and breaking down misfolded proteins linked to Alzheimers and other diseases . This is a process called autophagy.;

How Much Weight Loss Can You Expect In A Month On Intermittent Fasting

Many factors go into how much weight you actually lose on intermittent fasting. Weight loss will depend on your current weight, metabolism, what you eat, and your activity levels. Obviously, if you follow a healthy eating pattern and exercise every day or a few times a week, it will help you shed weight faster.;

Intermittent fasting may enable you to lose between 0.51.5 pounds a week. In 4 weeks, you could lose anything between 26 pounds.;

Intermittent Fasting For Weight Loss

People successfully lose weight with intermittent fasting for a good reason: fasting is the best way to lower insulin levels.;

Insulin is responsible for signaling cells to absorb glucose from the bloodstream and store excess energy as fat or glycogen.;

Accordingly, researchers can already predict 75% of the gain and loss in overweight people using insulin levels .;

Moreover, insulin prevents the breakdown of body fat .;

The fasting window stops nutrient intake, lowers insulin levels, and thus ends the bodys storage mode.;

Therefore, the body can start to deplete carbohydrate stores. Once they are empty, body fat can be burned for energy production instead.;

This mechanism is probably the essential goal of intermittent fasting for most people.;

Consequently, our bodies build up fat reserves during times of abundance to draw from this body fat during food shortages.;

Because we now eat at all times of the year and around the clock, we gain weight. In contrast, Intermittent Fasting restores the natural balance between eating and fasting.;

Accordingly, fasting corrects the hormonal imbalance that causes obesity .;

Women Intermittent Fasting What You Need To Know
