Fasting Is Easier When Youre Low

What I Eat In A Day (Low Carb + Intermittent Fasting)

Low-carb is easier when you fast.

Fasting is easier when youre low-carb.

The two inputs support each other. Rather than a vicious cycle, its a virtuous one. Fasting promotes fat-adaptation by upregulating fat-burning mitochondria, spurring the creation of new mitochondria, and reducing your reliance on sugar. Fat-adaptation makes going low-carb easier, because youre really good at burning body fat and dont get so many sugar cravings. Going low-carb makes you even better at burning fat and builds even more mitochondria, which is a prerequisite for fasting for extended periods of time.

If low-carb is going to work, you have to do it. If fasting is going to work, you have to fast. Anything that makes those easier is going to be good for your health. Thats where it all starts.

So Should You Avoid Fasting If Youre Not Low

Not necessarily.

Fasting while low-carb isnt the only way to do it. Many people have great success combining high-carb dieting with fasting, provided they also lift weights. One popular method is to go high-carb, low-fat on training days, with the workout coming at the tail end of the fast and the first meal coming after the workout. Then on rest days, you break the fast with low-carb, high-fat meals. The training stimulus increases insulin sensitivity and gives all those carbs a place to go .

But combining low-carb and intermittent fasting really does increase and accentuate the benefits of both practices.

Thanks for reading, everyone. Id love to hear about your experiences with intermittent fasting and low-carb eating. Do you find that the two go hand in hand, or have you also had success fasting with a higher-carb diet?


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

Blood Sugar And Other Tests During Fasting

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.

Lowest Insulin Levels Best Fat

The low-carbohydrate diet clearly produces the lowest average insulin levels throughout the day.

This is just a repeat of many previous studies. A low-carbohydrate diet produces much lower levels of the fat-storing hormone insulin. Period. This represents an advantage to all that want to burn more fat and store less body fat.

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.

Insulin: The Hormone That Stores Nutrients

We used to think that weight loss was a simple matter of mathematics, meaning as long as we burned more calories than we took in, we would lose weight. While calories matter, this calorie in/calories out model of weight loss overlooked a very important player, insulin.

Insulin is a hormone that is secreted into your bloodstream when you eat. Insulin tells your cells, particularly the ones in your liver, muscles, and fat, what to do with the nutrients that came out of the food you ate.

Specifically, insulin tells those cells to take in the glucose, fatty acids, and amino acids and either use them for energy or store them for later use. When it comes to managing your weight, the storage that you are most concerned with is the storage of fat.

Atkins’ Shared Benefits With Intermittent Fasting

1 MONTH RESULTS! Keto and IF Intermittent Fasting (from Slow Carb Diet)

While its currently popular to combine low carb living and intermittent fasting, its not strictly necessary. When adapted to a low carb diet like Atkins, your body is already trained to burn fat for fuel, and your diet is already helping to maintain your blood sugar levels. 2 Some people may find that if the caloric deficit that can occur while intermittent fasting is too great, it can also slow their metabolism as extreme energy deficits may suppress metabolism. 3 One helpful suggestion is that if you are pairing intermittent fasting with Atkins, make sure to consume adequate protein during your feeding window in order to help maintain muscle mass. An Atkins bar or shake is a great way to up your protein intake right before you begin your fast.Rather than using IF as an all-the-time diet, some people already living a low carb lifestyle use IF as a way to get back on track. If following a diet like Atkins 100TM, which allows for more fiber-rich carbohydrates per day, you may find IF slightly easier.

Following a low-carb diet puts your body in a hormonal state that favors fat burning. Intermittent fasting also puts your body in a hormonal state that favors fat burning. When you combine the two, you give body fat a one-two punch and accelerate your results. In this post, I explain how it works.

Get Adequate Nutrition And Learn About Good Fats And Veggies

A ketogenic diet can help you eat better, but this takes intention. Many people think keto is a license to eat bacon and cheese all day, says Fraser. You need to focus on also incorporating plants that are lower in carbs, such as nuts, seeds and leafy green vegetables.

Take some time to learn about which foods are low-carb and which contain healthy fats. Good fats you can eat in a keto diet include:

You should also get adequate protein by eating meat and poultry .

What Are The Side Effects Of Doing Low Carb With Intermittent Fasting

Not everyone goes on to experience adverse reactions, but intermittent fasting with few carbs in your diet can lead to some side effects.

However, these effects are temporary and not critical in nature, often passing within a few days after you get used to the new eating pattern and what your diet is composed of, so keep that in mind.

That being said, people have experienced some of the following symptoms as fasting drawbacks when combining intermittent fasting with fewer carbohydrates in their daily routines:

  • Trouble sleeping or falling asleep.

Doing Both Diets At The Same Time Calls For More Planning


“The keto diet is focused on getting the right level of macros in each day and intermittent fasting is all about reducing the amount of time you consume food each day,” saidregistered dietitian Staci Gulbin, MS, MEd, RD, LDN. Therefore, if you want to incorporate both plans into your everyday life, she recommended planning your meals and snacks a little bit more.

How Do I Combine Fasting With Atkins 20

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.

The Ketogenic Diet Reduces Your Lifespan

I found one study that claimed that a low-carb diet shortens a lifespan. When I took acloser look, I found that the researchers had a conflict of interest because they hadreceived fees from large pharmaceutical companies. Additionally, this âstudyâ was basedonly on questionnaires using peopleâs memories of what their diets had been like.

What Should I Eat When Im Not Fasting

Most of the research around IF does not provide strict guidelines around what to eat during your feeding window. But no matter which type of fasting you choose, make sure youre eating sufficient, quality calories during your feeding window. Reach for healthy foods such as fiber-rich carbs, healthy fats, and protein , you should also avoid sugar and refined carbs.

Because fasting elicits some of its beneficial effects through reducing insulin production, it has become popular to pair IF with a low carb or keto approach. We recommend eating high quality goods when youre not fasting, for inspiration, we recommend browsing our low carb recipes.

Can Fasting Help You Lose Weight

While it’s not a guaranteed weight loss plan, intermittent fasting is well known to kick-start weight loss, especially if the scales have stopped moving.

For the most part, weight loss is being accomplished by a dramatic decrease in their caloric daily intake. It is also due to a reduction in glucose and insulin levels which enables you to be in nutritional ketosis. Your body has switched to fat-burning mode.

The Ketogenic Diet Is Not Sustainable

Our bodies werenât designed to take in the high volume of sugar a typical Americanconsumes in a day. Excess sugar consumption results in high blood sugar and fat storinghormone levels, which ultimately load up the liver with fat. Burning ketones for fuel,which is what one does on a keto diet, is much healthier than burning carbohydrates.Your brain can use ketones for fuel indefinitely. I explain why this diet can besustained for long periods of time in this video.

Benefits Of Pairing Low

Most of the low-carbers I know end up experimenting with intermittent fasting at some point in their journey, and most of the IFers I know end up drifting toward low-carb eating as time wears on.


Is it just a case of overlapping interests? Is it because when you stumble upon one big lie perpetrated by the expertsthat cutting carbs will give you heart disease and leave your brain starving for energy/you must eat 6-8 small meals a day or else risk starvation mode and slow metabolismyou start questioning all the other advice they give?

It might be some of that. But a big reason why intermittent fasting and low-carb eating tend to converge is that they are synergistic. Doing one makes the other work better, and vice versa.

Are There Any Known Health Risks Of Doing Keto And Intermittent Fasting Together

Pin on Keto

As for long-term risks, people with seizure disorders have been on the ketogenic diet for decades and demonstrate excellent health, DAgostino says. Though, like any diet, it all depends on what foods youre eating. A keto diet rich in bacon and butter is different from one rich in avocado and olive oil, and poorly planned keto can lead to nutritional deficiencies. Because adding IF may make you cut calories too drastically, you may also lose too much weight or lean mass if you take the restriction to the extreme. To maintain muscle mass, he recommends consuming 1 g per kilogram of body weight in protein every day.

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.

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

How Long Can We Last Without Food

Once you start fasting, you may feel ravenously hungry as your mind is flooded with images of your muscles disintegrating into thin air. This is simply how your mind reacts to the threat of starvation just because it feels like you will lose all your muscle and starve doesnt mean you will.

In fact, Mahatma Gandhi survived for 21 days without food while only taking in sips of water. During times when people had no food or water at all, they were able to survive for 10 to 14 days. However, these are just anecdotes what does the science say?

Many studies have been done during hunger strikes and religious fasts confirming that humans have the capacity to survive even longer than Gandhi did during his fast.

One monk, for example, set out to do a 40 day fast with medical supervision while maintaining his daily activities in the monastery. After 36 days, the medical professionals had to step in due to profound weakness and low blood pressure when standing. Although the monk fasted for 15 days longer than Ghandi, the medical professionals were able to stop the fast in time so that he could recover.

Another study tracked 33 political prisoners who were on hunger strike. The prisoners fasted for 6-24 days before being hospitalized for dehydration due an inadequate intake of fluids and electrolytes . Breaking their fast was described as being uncomplicated.
