What To Eat While Intermittent Fasting

Should You Do A Low Carb Diet When Intermittent Fasting?

During your fasting window, you shouldnt eat anything. During your eating window, enjoy nutrient-dense keto foods like healthy proteins, vegetables, and fats.

Avoid breaking your fast with processed foods, carb-heavy meals, and dirty keto foods, as these can hinder the health benefits of fasting in the first place.

Bring On The Benefits

After all of the evidence presented, its hard to argue against the keto diet or intermittent fasting. They seem to benefit so many different physical conditions and diseases, along with having benefits for non-disease related functions.

It is said that the benefits of keto are basically due to the fact that it activates similar mechanisms to that of fastingthis is true. Fasting and ketosis both seem to call upon ancient biological pathways to promote stress resistance, survival, and longevity.

While we advocate both highly, dont just jump right into fasting and ketosis without a bit of experience first. It takes some time to both metabolically and psychologically adapt to dietary regimensespecially prolonged fasting. Maybe try out TRF first along with a keto diet, and gradually progress your fasting periods.

If youve had a great experience with keto, IF, or both, tell us in the comments! Wed love to hear.

What Are The Types Of Intermittent Fasting

There are many types of IF but they can generally be grouped into 3 different categories.

  • Time restricted eating This type of intermittent fasting breaks the 24 hour day into fasting and feeding windows. Popular forms of time restricted eating include: 16:8, 12:12, and 20:4.
  • Alternate-Day Fasting While this may sound like you are supposed to fast every other day, this is actually the term used to describe a method of eating normal one day, and the next day consuming very few calories . Another form of alternate day fasting is the 5:2 method, where you eat normal for five days, but fast or eat a very low calorie diet the other 2 days of the week.
  • Longer fasts As people become more acquainted with IF, they may start to read about 24+ hour fasts. We dont typically encourage people to follow this protocol, simply because we believe that low carb is a beneficial way of eating that provides a complete nutritional profile that doesnt require you to deprive yourself of food for days on end. We encourage anyone who is planning on doing a longer fast to consult with a healthcare professional who specializes in this approach.

Example Meal Plans For Every Fast

In this section, youll find one-day meal plans for the most popular intermittent fasting regimens.

These recipes are nutrient-dense, low-carb, high-protein meals that compliment the benefits of your intermittent fast by continuing to maintain healthy blood glucose, insulin, and ketone levels while providing all the macro and micronutrients you need to maintain a healthy metabolism.

When planning how to break your fast, whether its at breakfast or lunch, steer clear of high-carb foods like fruits or grains that may spike blood sugar and lead to a crash later in the day. If you follow a Keto or low-carb lifestyle, youll already be familiar with eating this way.

Keep in mind that your portions will vary based on your individual needs. The goal isnt to consciously limit calories, though it will probably happen naturally.

Also, dont feel pressure to make every recipe. Theres no shame in eating leftovers, and batch cooking ahead of time often goes hand in hand with meal planning.

The Ketogenic Diet Keeps You Satisfied

Another great perk of the keto diet is its high level of satiety.

Not only does ketosis itself tend to stifle hunger, but the high level of healthy fat in the keto diet also makes it much easier to stay satisfied in a fasted state and eliminates those intense feelings of hunger and cravings throughout the day.

This is perfect for someone doing intermittent fasting.

Wont Intermittent Fasting Burn Muscle

That depends on the person and the duration of the fast. During fasting, the body first breaks down glycogen into glucose for energy. After that, the body increases body fat breakdown to provide energy.

Excess amino acids are also used for energy, but the body does not burn its own muscle for fuel unless it has to.49

Some studies, however, suggest that leaner individuals are at higher risk of lean body mass loss, and even reduced metabolic rate. Yet it appears this is less of a concern with overweight subjects.50

In my experience with over 1,000 patients on various intermittent fasting regimens, I have not yet seen a single case of significant muscle loss.51Learn more

Autophagy: A Nobel Prize Winning Lifestyle Hack

Low Carb Eating and Fasting Lose Weight Intermittent Fasting

In 2016, the Nobel Prize in Physiology or Medicine was awarded to Yoshinori Ohsumi for discovering some of the mechanisms of autophagy the process by which the cell devours itself. Superficially, this sounds like a terrible thing for our cells to do until you consider what is really taking place.

When our cells undergo the process of autophagy, non-essential parts like damaged proteins are recycled and invading microorganisms and toxic compounds are removed. This means that autophagy plays an important role in stopping the aging process, reversing disease, and preventing cancer, but it doesnt happen all the time.

Fasting, protein restriction, and carbohydrate restriction are the three main ways that can initiate different autophagic processes all of which are not the same. This is part of the reason why a ketogenic diet has so many positive effects, and it also shows you why intermittent fasting is a way to improve your diet even more.

Though this is reason enough to fast more, autophagy isnt the only upside of intermittent fasting. In fact, the combination of keto and fasting can provide us with a wider array of benefits.

Skipping meals and severely limiting calories can be dangerous for people with certain conditions, such as diabetes.

Benefits Of Intermittent Fasting

There are several advantages to intermittent fastingboth physiological and psychological.

The first benefit may be for those looking to lose weight. While the research isnt definitive on this, many people report that they find it much easier to stick to than traditional diets where youre forced to consume much fewer calories than you need.

Some might find it easier to simply not eat than to chronically maintain calorie intake well below their means. This could be more of a psychological effect than something physical. In addition, IF may make it easier to meal plan . If its one of your fasting days, you dont have to worry about preparing a meal, making time to eat, or worrying about WHAT youre going to eat. When done in the proper context, this could free up some time to be productive in work or hobbies.

Intermittent fasting is in its infancy as far as research goes, and most studies have been conducted in mice.

How Do I Combine Fasting With Atkins 20

Intermittent Fasting For Beginners

While we do not suggest that you combine these two approaches. However, if you are keen on combing the two, we recommend starting your low carb diet for 23 weeks prior to fasting so that you can safely and completely adapt your body.

We do suggest pairing intermittent fasting with an Atkins 100-type approach, which allows for a few more fiber-rich carbohydrates each day. This can reduce some of the stress that may occur when strict carbohydrate restriction is paired with IF. Atkins 100 also more closely resembles the research that has combined low carb eating with fasting.

Why Does My Blood Sugar Go Up During Fasting

While this does not happen with everyone, it can occur due to hormonal changes that occur during intermittent fasting. Your body is producing sugar in order to provide energy for your system. This is a variation of the dawn phenomenon and in general is not a concern as long as blood sugars are not elevated the rest of the day.45

Will I Lose Weight

Most likely.64 If you have weight to lose, it is extremely likely that you will lose weight if you do not eat.

In theory, its possible to eat more after fasting, of course, cancelling out the weight lost. But studies generally show that most people tend to eat significantly less overall.65

I call intermittent fasting the ancient secret of weight loss because it might be one of the most powerful dietary interventions for weight loss, yet it has been mostly ignored by doctors and dietitians for a long time.66

Intermittent Fasting Without Keto: Why It Works

Many people turn to intermittent fasting and the keto diet for weight loss. Why? Because these two methods are much more sustainable than calorie restriction long term, but can you benefit from intermittent fasting without eating keto or do you need to do both to achieve the best results? Find out in todays blog post.

Blood Sugar And Other Tests During Fasting

Low carb and intermittent fasting help fatty liver
When I fast on just chicken broth my blood glucose drops to 65 and then on the 5th day to 55 mg/dl.Have you observed a drop like this in your fasting patients?

We often see this drop during fasting.

Should i worry if my blood sugar while fasting goes up to in the 140s ?

This is quite common, and due to the breakdown of glycogen or the production of new glucose in response to some of the hormonal changes of fasting. It is neither good nor bad.

Think of it this way. Your body is simply moving sugar from its stores and pushing it into the blood. Here your body has a chance to burn it off.

I purchased a glucose and ketone meter last week. Measured my glucose on Friday after fasting for about 21 hours and the reading was 3.6 mmol with the ketones at 1.9 mmol. It worried me a bit that the glucose was this low, should I be worried? On Saturday I went for a 6 km trail run at a high tempo and my glucose reading afterward were 2,4 mmol. I would like to stay in ketosis, but my fluctuating glucose readings are making me nervous. I do not experience any of the low glucose symptoms, but I tend to become paranoid when the numbers dont look right!

Listen to your body. If you feel unwell, then stop. Otherwise, if you are worried, reduce the fasting duration.

Carbs And Hormone Function

Low carb and ketogenic diets have been shown to help with weight loss and metabolic health. However, carbs support hormone function and the stress caused by the lack of glycogen may cause hormonal disruptions. Women may even experience amenorrhea. This type of amenorrhea is called functional hypothalamic amenorrhea . It is most commonly caused by too few calories, too few carbs, weight loss, stress or too much exercise.


Leptin is another hormone that may be affected by a diet too low in calories or carbs. Leptin is produced by your fat cells and it helps you feel full. Moreover, it contributes to regulating womens reproductive hormones. Low carb diets reduce leptin production .


Fasting and a keto diet increase cortisol levels. Cortisol has many benefits, including reduced inflammation and fat loss. However, too much of a good thing can become a bad thing. Too much cortisol can have the opposite effect and cause fat storage and lower estrogen production.

Thyroid Function

T3, the active thyroid hormone is sensitive to calorie and carb consumption.

Atkins And Intermittent Fasting

For many people, low carb diets and intermittent fasting go hand-in-hand. IF is not necessary on a low carb diet, however, because your body will already be trained to burn fat for fuel and your diet will already help control your blood sugar levels. But as long as you are meeting your caloric requirements during your eating window, fasting after dinner for 12 to 16 hours each night could give your digestive system a needed break. This is also beneficial as nighttime eating is often when mindless snacking on hidden carbs occurs.

If youd like to try IF while living low carb, try making your calorie cutoff around 6-7 p.m. Squeezing in a morning workout in a fasted state can also help put you in the fat-burning zoneas long as you feel up to it.2 Just remember that chronically consuming too few calories has the potential to slow down your metabolism, which will hinder your weight-and fat loss goals.

While IF has become increasingly popular, it is still a somewhat controversial approach and is not recommended for those with eating disorders or those who are pregnant or nursing. As with starting any new diet or exercise routine, consult with your doctor or healthcare provider for guidance on whether intermittent fasting is right for you.

I want women to know it is possible and we all can do it. I also want to tell women to stop putting ourselves on the back burner just because we have children and busy lives. We cannot be our best selves to our children or anyone else if we are not truly happy with who we are.

The Keto Diet And Ketoacidocis

#intermittentfasting #cleaneatingresults #intermittent # ...

Ketoacidosis is a serious condition that is usually associated with diabetes, but not always. It causes dehydration, poor appetite and difficulty breathing. I found this case where a lactating woman on the ketogenic diet suffered from ketoacidosis particularly revealing. Women in general, but particularly lactating women need more carbs for proper hormonal function.

I am not claiming the keto diet is dangerous and should not be practiced. What I am saying is that if you are doing both intermittent fasting and the ketogenic diet, proceed with caution.
