A Fast way to Ketosis: Does Fasting and Keto mix?

What is Ketosis?

There are a lot of moving parts when it comes to Ketosis. Ketosis is a direct product from the ever popular Ketogenic Diet (keto Diet for short). Ketosis is defined in the dictionary as: a metabolic state characterized by raised levels of ketone bodies in the body tissues, which is typically pathological in conditions such as diabetes, or may be the consequence of a diet that is very low in carbohydrates (1). In other words – it is completely and totally unique at the genetic level.

Life Changing

Ketosis is a life changing event…yes I said event. I have been in ketosis a few different times, and it has many health benefits. My favorite benefit in the short term is the clearing of “brain fog” or just gives a person mental clarity as well as extended energy levels.

By implementing the Ketogenic diet into my fasting regimen, I have reaped the benefits of creating a fast way to Ketosis. Through many trial and error runs and experimentation with different diets and workouts, I have figured out what works for me. Throughout this article I am going to go into depth on how I have achieved Ketosis with the help of fasting and the keto diet.

I will be laying out the moving parts of ketosis, fasting and the keto diet in a way that should be easy to understand. More importantly this will allow you to start down you path to ketosis today. Before we get into how to achieve Ketosis, lets briefly go over the keto diet.

What is the Ketogenic Diet?

The keto diet has similarities to the paleo diet, if you remember that one. This diet consists of high fats and low carbs and protein. There are four (4) different variations to the keto diet. The most research done is on the Standard Ketogenic Diet or the SKD, this is the diet I will be focusing on. The other three keto diets are more targeted to a specific athlete type or someone to gain something specific. For example maybe a person wanting to gain muscle mass. I would encourage anyone to test out what they feel fits their specific lifestyle. To get an idea of the other three, I have listed them below along with the SKD.

Standard keto Diet (SKD)
75% fats – 20% protein – 5 % carbs

High Protein keto Diet
60% fats – 35% – 5% carbs

Cyclical keto Diet (CKD)
5 skd days followed by carb re-feeding

Targeted keto Diet (TKD)
Add in carbs around specific workouts

I know when I start out on a new diet plan, it always seemed to intimidate me. With specific numbers, percentages and strict schedules. The keto diet can seem intimidating but it truly is simple and binary. To achieve Ketosis, sticking with a high fat diet is a must. Having said that you don’t need to be in a state of “ketosis” for the diet to be effective or even to lose weight.


I like to relate everything within my posts to my personal experience. I find it easier to understand for readers andmakes it seem a bit more attainable – anybody can do it. When I started down the path to get into ketosis, I stuck with the regimen pretty strictly and I achieved my goal. I have loosened the reigns on my “keto diet” however. The goal behind the diet (in my mind) would be to lose weight, get in shape and have a better cognitive outlook. I don’t want to hate my life and be looking forward to a “cheat meal”. This diet will satisfy all of that.

The idea behind the diet is that this will create ketones. Ketones are another way for the body to burn energy. I would suggest that the majority of the population runs their energy source from carbohydrates. When the body has high ketone levels the body will start to burn fat instead of carbs, which is the beginning of ketosis.

Ketones have been used for years in medicine. Ketones create a reduction in blood sugars and insulin. Ketones get stored in the liver as fats and transfer to brain as a new type of energy.

Fasting and keto – The Dynamic Duo

Fasting has changed my lifestyle – for the better in so many aspects. I started fasting before I jumped on the keto train, which is somewhat backwards of the way some start. Fasting and keto were meant for each other. I like to talk about hacks to get in shape faster but this truly is the biggest hack of all.

The benefits of a keto lifestyle outweigh any other diet that I have been involved with, I may be biased but it works for me! I implemented intermittent fasting with the keto diet when I first started out to achieve ketosis at a faster rate. The reason fasting boosts the time frame up for ketosis is a few different factors

Autophagy, Fasting and Ketosis
These three terms go hand in hand. Autophagy is achieved quicker by fasting. When your body is in a state of autophagy it is much easier to get into ketosis. To achieve have some questions about autophagy read my article on autophagy here – How does Autophagy Work? – does it really matter? – spoiler – it does.

Fasting to Ketosis

This process can be simplified to understand the mechanics of the ketosis beast. I used intermittent fasting when on the keto diet. I describe intermittent fasting as not eating any calories until 2:00 pm. Then having a 100-150 calorie intake and not eating the bulk of calories until the evening; between 6-8 pm. This is the diet that I have adapted to my situation and it works for me. Playing around with the parameters is something you will find yourself constantly doing.

Disclaimer: “keto Flu”
In your run to get into ketosis – you may come across some unpleasant…feelings. There is what is called the “keto flu”. This will produce flu like symptoms when creating ketones. The main reason is because your body is so used to using carbs for fuel the body doesn’t know what is going on. It will make you want to give up, don’t. You can get through this by knowing this might happen. Just have to hang in there.

There are plenty of different types of fasting techniques and feel free to use whatever variations you want. To achieve are struggling with a fasting regimen check this article out – The Adaptable Intermittent 5:2 Diet?. This article will clear up the simplicity of how to fast.

When you are in ketosis everything in your body will change. You appetite will be suppressed, you will have extra energy. You will have lost significant weight (if you had some to lose). There are many factors when testing to see if you are in ketosis. Below I have compiled a list of the most common and free ways to check in on the ketosis. These are the key elements I used when testing.

  • Bad Breath
  • Appetite Suppression
  • Boost in Energy – like a giant boost
  • Mental Clarity
  • Digestion will be altered (short term)
  • Insomnia (short term)

    You can test for ketone levels more accurately with tests. These blood prick tests may cost about $30-40 but you can have the peace of mind knowing your levels. There is also urine strips you can you to check color in relation to ketone level. I prefer the “state of mind” way. And honestly my goat isn’t to have “exact” ketone levels. I want to change my lifestyle and it is achieved through this!

Is Ketosis and the Keto Diet for you?


I am a strong believer that everyone should try the keto diet at least one time. But their are some indicators to consider deciding if the keto diet is for you. To achieve simply aren’t a fan of foods with high fats, this diet may not be the right direction. To achieve are a vegetarian or vegan this will be challenging for you as well due to the diet choices. To achieve are an elite athlete or ultra athlete you may want to reconsider the keto diet.

You can always adapt the keto diet to your lifestyle, just make it your own altered diet.

Summary – The Good Stuff

A fast way to Ketosis – The things to remember when changing your lifestyle and diet. This will take some research to fully understand the keto diet. The foods that go along with the diet as well the intermittent fasting techniques. The fasting will boost your time to ketosis tremendously and I encourage it. There may be a “keto flu”, just prepare for it and know that if will more than likely happen. Be prepared to battle the headaches and stay on track.

Ketosis and more importantly the keto diet has changed my way of life. I have more energy for my kiddos, my brain is on an entire different wave length and I have the energy I missed having as a younger version of myself. I hope you can conquer this transition to ketosis to fully understand the meaning of “new energy”. To achieve have any questions or have a “ketosis story” of your own I would love to chat about it!

Until then…

Thanks for reading and have a pleasantly uncomfortable day

    I have been considering the keto diet for a while now.  Now I see there are different variations, and I am not sure which one is the best for me.  If I want to lose excess weight quickly (I know it doesn’t happen over night) which one will work for me?  Also, where do I get all the information I need to get started?  Would I be better off looking for a book or online for website information.  I really don’t know where to start or what exactly is involved.

      Thanks for stopping by and great questions!

      The keto diet has changed my life, and I suggest you trying it out. There are a few different variation to the keto diet, but the standard plan is the best one (here below)

      Standard keto Diet (SKD)
      75% fats – 20% protein – 5 % carbs

      It truly is that simple to follow. Another good way to think of it is eat less than 50 carbs a day. This can be simple by following these rules (it’s what I do)

      EAT – Meats, cheeses, eggs, nuts (with high fat, I like almonds), poultry, olive oil

      DO NOT EAT – Low fat dairy, bread, grains, nightshades (potato etc.), any thing with high carbs – like nothing fast food or in gas stations, most fruit isn’t good either

      So to get started I would say eat meat, cheese, and nuts. And stop eating bread, pitas, lean foods, drinking soda or anything with sugar.

      When I stick to a keto diet this is my meals

      breakfast – black coffee, and that is all I have til 2 pm but if you were to eat lunch…

      lunch – some nuts, or a meat and cheese sandwich

      Dinner – steak, chicken breast, cheese of any kind

      There dozens of recipes you can mimic almost any food you like, like bread. I absolutely love bread. There are great recipes for making “keto bread” “keto pizza” you name it. The problem is that it takes time and you have to become quite the chef. That is why I stick to caveman stuff like “me want meat” haha. I have a video below check out, let me know if you have any further questions!

    My partner was looking into taking on the Keto diet a while back but she seemed to bump into more horror stories than success stories – I’m wondering what your opinion is on this?

    For instance, one of her friends pointed out that the ‘flu’ side of the process often ends up like a from of gastrointestinal distress – she really didn’t fancy going through that! 

    Have you experienced this form of the keto flu? Is there any truth in it?

      Thanks for the great questions. 

      The Keto diet is a lifestyle change, not just a diet. And yes it may mess with your insides a little bit. But this is common sense, if you aren’t used to eating a high fat diet (that is what keto is) then you will more than likely be confusing your body for a week or 2. 

      And every person is different, genetically. Some people may be allergic or very sensitive to high fat foods. I have heard horror stories as well Chris, however they are skewed most of the time…let me explain.

      Like I sated earlier it is a body changing event and it will make you feel a little funny, after all you are changing the way your body has been fueled for years, switching from sugar and carbs to fats. And the other point is, most people don’t give it a chance even a month on the keto diet sometimes isn’t enough to adapt your body.

      The keto diet is also hard because most of the foods can be a little $$$ and you may have to “make” most of your meals. Like I said it is a dedication, I am here to tell you though it is well worth it my friend. If you haven’t read my article on autophagy, check it out in link below – another great benefit to Keto and fasting! Hope this helps, if you have any other questions please let me know.

    Hello there,

    I was always very fascinated by how different diets can benefit or vice versa, give disatvantage to human being in many unique ways. However the one aspect that stood out for me the most and sparked the biggest interest in me was diet’s influence on person’s mental health. Going into this article I didn’t know much about Ketosis and Ketgenic diets, so I was very much looking forward to learning something new and interesting today. The part of this article which I found to be the most captivating to me, was where You explain health benefits of Ketosis, especially the clearing ”braing fog” part as well as how Ketogenic diet can create a way or path to Ketosis ( I just really like the spiritual things!) Thanks for this beautiful and informative article, I really enjoyed it! Keep up the great work 😉

      Thank you for stopping by!

      Yes the clearing of brain fog is my favorite part of ketosis. I am glad you like the article, if you have any further questions please let me know.

    Hello Nic,

    I have been following your Keto Diet closely. I haven’t personally tried it before but from the way you’re talking I could see that it has some positive impact on the body. Especially when it comes to weight loss and helping boost your brains cognitive level. It looks like this diet is more of fats than Carbs and protein. That sounds reasonable in helping you lose weight since too much cards in a diet can affect your weight.

    But there were some things you mentioned that makes me a bit hesitant about trying this Keto diet, especially about the symptoms of “Keto flu” and “Bad breath”, they really scare me off trying this. How long will the bad breath and flu continue before they stop? Won’t they become a problem at the end as bad breath is major problem in today’s world.

    Please let me know your thought on this before I ever give this a try.

      Yes you are spot on with the keto diet and the fats being better and making it easier to lose weight. I think there might be some confusion between the “keto diet” and “ketosis”. Let me explain.

      You can lost plenty of weight and only be on the keto diet without going into ketosis. Ketosis will take some time and very diligent dieting to get on. Almost always requiring a 24 – 48 hour fast. So you really don’t need to worry about the keto flu or bad breath.

      If ketosis is the goal you have in mind, the flu will be short lived and the bad breath will also be a short stint. If you have any other questions please shoot them my way, thanks!
