What Are The Disadvantages Of Combining If With Keto

Keto and Intermittent Fasting | How to Combine Them | Thrive Market

The main weak point of combining intermittent fasting with the keto diet is that it is extremely restrictive.

When we talk about healthy weight loss that you would maintain for the rest of your life, we always tell you that your diet should be sustainable. You should opt for a lifetime change in your eating habits and not a short-term crash diet.

/5how Are Keto And Intermittent Fasting Different

While the Ketogenic diet focuses on the intake of low-carb foods and high-fat foods, which is then used as fuel, Intermittent Fasting works by following a time-restrictive eating schedule. Simply put, while the Ketogenic diet emphasizes lowering carbs and using fats as a primary energy source to lose weight, Intermittent Fasting works by moderating your eating patterns, without really restricting anything.

Intermittent Fasting And Keto Meal Plan

The following intermittent fasting and keto meal plan can be applied to essentially every method of intermittent fasting. This includes circadian rhythm fasting, and methods tailored specifically to women.

Each of the meals on this list is made with simple whole foods, is easy to prepare, and packed with healthy fats.

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.

Intermittent Fasting And Cancer

Can You Combine Intermittent Fasting and Keto? â Kiss My ...

Although there is little to no literature on the effects of 2 or 3 day fasts on muscle loss in humans, many clinical trials are currently being conducted on the effects of 2 or 3 day fasts on cancer patients.

In initial case studies, people who were undergoing chemotherapy voluntarily fasted for anywhere between 48 to 140 hours. Each person reported fewer side effects and improved quality of life regardless of how long they fasted.

This may suggest that fasting for 2 days to a week can have a protective effect on the cells in the body while they are undergoing intense bouts of toxicity.

Other studies in animals have found that fasting was possibly as effective as chemotherapeutic agents in delaying the progression of different tumors and increased the effectiveness of chemotherapeutic drugs against melanoma, glioma, and breast cancer cells. Although this research may not apply to your life, it does suggest that intermittent fasting can help support your body in times of toxic stress.

A Ketogenic Diet Makes Fasting More Manageable

If achieving ketosis is your goal, intermittent fasting is a must-try strategy.

But what if youve been on a keto diet for quite some time now? Hayley Cimring, a registered dietician, mentions that eating a ketogenic high-fat low-carb diet will make fasting easier and more manageable.

This is because a keto diet will help you become more fat-adapted, which will enhance your ability to perform an extended fast without feeling lethargic, depressed or unbearably hungry, says Cimring.

Sustained Fuel Source Between Meals

Fat digests much more slowly than carbohydrates, and ketones pack more energy per unit than glucose.2

When youre on a well-formulated high-fat keto diet, your blood sugar rarely drops to a point where you get hunger cravings and doesnt spike to a point where you lose focus.

Ketones are also effective at suppressing ghrelin, the hormone that makes you feel hungry.

Both intermittent fasting and keto diets have been shown to reduce hunger.1 And ketogenic meals are more satiating, leading to a reduction in food cravings. This in turn supports an intermittent fasting schedule that calls for extended periods without eating.

Keep Up Your Water Intake

During the non-feeding period, make sure you keep yourself hydrated by drinking a higher amount of water.

The rule of intermeeting fasting is not extended to water intake.

Hence, you can drink as much as water you want during the feeding as well as non-feeding period. No restrictions applied here!

This will prevent fatigue and keep you energetic throughout the day.

May Smooth Your Transition Into Ketosis

How to Combine a KETOGENIC Diet with INTERMITTENT FASTING to Quickly Lose Belly Fat

Keto is about switching your body from using carbohydrates for energy, to turning fat into ketones. The typical way to do this is by cutting carbs and increasing fat intake in your diet. For many people this transition can take some time and it comes with a number of unpleasant side effects known as keto flu.

IF speeds up ketosis and smooths the transition. When you fast, your insulin levels drop, causing your body to use its stored carbs . Once these are depleted your body begins using fat for fuel. 12

Think of fasting as a way to jump start ketosis.

Try The Most Popular/effective Method

The most popular method is 16/8. Otherwise known as the timed restricted eating routine. This involves 16 hours of fasting and 8 hours of eating. During the eating window you should consume balanced keto meals. Either 2 large meals or 3 smaller meals. Avoid snacking to maximise results and to maintain a strong digestive system. Overeating can cause your digestive system and your metabolism to slow down. This can cause stomach issues and weight gain.

Intermittent Fasting Health Benefits

Fasting is entirely natural. Only this way, our ancestors could survive winter, when food was scarce or not available at all.

Accordingly, many indigenous peoples still do not eat for days if they were not successful in hunting. Although we dont rely on this survival mechanism anymore, we can realize its benefits by fasting regularly:

Can Intermittent Fasting Work Without Keto

Intermittent fasting can indeed work without keto. It has been used as an eating style for centuries for weight loss and other benefits.

Following a fasting routine with keto will still allow you to reap its benefits.

The reason being for combining the two diets is to maximise benefits. Also, to reach ketosis quicker which encourages excelled fat burning and use of fat storage.

Many weigh up intermittent fasting vs keto. Both have become extremely popular for weight loss. Some use them for the other health benefits. And, both are very effective.

To put it simply, both of these will work effectively for whatever you wish to try them for. Whether that be weight loss or improving heart health. There is not enough evidence to suggest one is better than the other. It all depends how much work you put into the diet and also on the individual themself.

For most, intermittent fasting may be easier to sustain longer term due it being more of a lifestyle change as opposed to a dietary change. Again, it all depends on the individual.

Like all diets, there are some ups and downs. For this combination diet, they are as follows:

Atkins And Intermittent Fasting

Intermittent fasting and keto diet for Weight Loss and its ...

The Atkins diet, which was developed in the 1960s, is the classic low-carbohydrate diet par excellence.

But this is precisely where its weaknesses lie. Since nobody knew that protein also strongly stimulates insulin until the 1990s, people started to replace carbohydrates with lean protein .

For this reason, classic low-carbohydrate diets such as the Atkins diet are not nearly as effective at losing weight as intermittent fasting.

In contrast, pure fats such as extra virgin olive oil cause virtually no insulin response at all.

Above all, lean protein can lead to strong insulin reactions without the protective effect of fat. Unfortunately, due to fats medial demonization, we have begun to remove fats from natural foods.

Since it is far more effective in terms of health and weight loss to restrict protein and consume healthy fats, the Atkins approach was doomed to fail.

The Number Of Calories You Eat

All intermittent fasts have eating windows, which is the period in which you can finally sit down to a meal. What you choose to eat during these windows can undo all the healthy progress youve achieved through intermittent fasting.

Sure, youre still sticking to keto rules on your diet, but keto is more about reducing carbs than it is calories. If youre not careful, you can overload on calories, which would be disastrous. When you eat more calories than what your body burns, you gain weight.

So How Can They Work Together

“Since many of the benefits seen in intermittent fasting are also seen in the keto diet ,” Lakatos says, “Fllowing both diets at the same time may provide additional benefits.”

For starters, fasting encourages your body to use fat for energy rather than glucose and so does the keto diet, which means “intermittent fasting may help those following the keto diet to achieve ketosis more easily,” Lakatos Shames says.

“Research also shows that intermittent fasting increases body fat loss, which could accelerate body fat loss for those on the keto diet,” she says. “Other studies have shown that intermittent fasting may help to maintain muscle during weight loss and also be beneficial for energy levels. This may be especially helpful for those following a keto diet who are looking to lose some weight and have better exercise results.”

The Right Way To Start An Intermittent Fasting Keto Diet

How To Pair Intermittent Fasting With Keto For The Best Results | Diet Tips w/ Jeremy

At the Cleveland Clinic, practitioners do not advise people to start both keto and IF at the same time. Its a huge shock to your system to switch from glucose as fuel to ketones, and implementing IF is a significant change, says Kwasnicka. For that reason, people would start with keto. After being on the diet for a couple weeks to months, they might consider IF.

Its also important to choose the correct timing. For their patients, Kwasnicka suggests a 12- to 16-hour fast. For many people, not eating 12 hours a day is a natural habit anyway and doesnt require skipping meals.

To start, consider delaying breakfast to get your body accustomed to going longer stretches without eating, suggests Shemek. When youve adjusted to your new eating pattern, reintroduce breakfast earlier in the day and extend your overnight fasting time, as eating breakfast not only leads to better cognition, but also improved metabolism and insulin sensitivity, according to a study published in August 2018 in the American Journal of Physiology-Endocrinology Metabolism. As for the length of time to stay on keto-IF, she recommends doing keto-IF for no more than six months and then transitioning to a more standard low-carb diet.

Can You Combine Intermittent Fasting And Keto

Combining fasting and keto is not uncommon. In fact, many epilepsy centers will initiate the keto diet with a 24-48 hour fast . This has been common practice since the early days of using keto as an alternative therapy for epilepsy, the reasoning being that fasting helps speed up ketosis.

Furthermore, keto and IF have shared origins. Fasting is a precursor to the keto diet, with its use for this purpose dating back to at least 500 BC. Hippocrates was one of the first to suggest it to treat epilepsy, and the Bible also has passages that claim not eating is a cure for this malady.

Fast forward to the 20th and keto replaces fasting as a treatment for epilepsy. It all began when researchers at the Mayo Clinic found a way to mimic the metabolic effects of fasting with a low-carb, high-fat diet they called the ketogenic diet.

Keto dieters are well aware of the strong ties between fasting and keto, which is why they often combine the two. Their goals with this approach include:

  • To get into ketosis faster
  • To reduce calorie intake
  • What Is A Good Breakfast For Fasting On The Keto Diet

    A typical keto intermittent fasting breakfast should include high fat, lean protein and no carbs. Any type of eggs are ideal for a keto diet. Low carb vegetables are a good choice too. This includes breakfast vegetables like mushrooms, tomatoes, kale, peppers and spinach.

    Low carb options are the best to break a fast as it will inhibit a spike in blood sugar levels.

    Should They Be Combined

    For the most part, combining the keto diet and intermittent fasting is safe.

    However, if you are pregnant or breastfeeding you may want to avoid intermittent fasting.

    The same goes for those who have an eating disorder.

    If you have certain health conditions, including heart disease or diabetes, you might want to talk to your doctor before giving intermittent fasting or the keto diet a try.

    While its safe to do both of these methods, you might want to keep in mind that it might not work for everyone.

    Each persons body reacts differently.

    If you are doing the keto diet, it might be difficult for you to fast as well, or you might experience some adverse effects.

    This means on some days you might feel cranky or irritable, you might overeat on those non-fasting days, and you might even have some increased fatigue.

    Intermittent fasting wont necessarily get you into ketosis faster but for some people, it can get you there when combined with the keto diet.

    Following a keto diet can be enough for anyone looking to cut down on carbs to help them with weight loss.

    When you combine the keto diet with intermittent fasting, you may reach ketosis faster than if you did the keto diet alone. It can also help with greater fat loss.

    However, this method might work wonders for some people but do nothing for other people.

    Some people should avoid this combination altogether.

    Some people have luck with one or the other as well.

    Each persons body will react to these methods differently.

    Combining The Keto Diet And Intermittent Fasting Is Not The Best Idea

    If you want to start one of these diets, it is advised to stick with only one of them. Intermittent fasting has fewer risks.

    The Keto diet has been dangerous for those who have type 1 or 2 diabetes. Blood sugar and insulin regulation are significant, and diabetics can cause strange side effects.

    Some of these side effects are fatigue, brain fog, dehydration, bad breath, flu-like symptoms known as the keto-flu. The combining of both the diets is not an easy one. There are several constraints when it comes to these two diets together.

    For keto dieters, they have shallow carb limits. Many people are unable to stick to the low-carb diet in the long term. Adding intermittent fasting to the mix can be too much for them as far as time goes. Once this happens, the diet can discourage you and make you go back to your regular eating routine.
