Is Ketosis Safe? Why It’s Important To Know

Is Ketosis Even Safe? The difference between ketosis and ketoacidosis

Being in ketosis is an all-natural state. However, is ketosis safe to be on a regular basis? Is it even right for you? Come learn more about what it means to be in ketosis.

New to the low carb, keto diet? Have you been asking yourself is ketosis safe? It’s a fair question, especially when first embarking in this lifestyle.

The rise in popularity of the ketogenic diet means that more people are becoming aware of a low carb keto lifestyle.  They have either tried a keto diet or no someone who has.

Although it’s great to see more people interested in ketogenic dieting, it does not negate the responsibility to find out if it’s the best option for you.

Unfortunately, with the spike in popularity, has also come a lot of confusion. Mainly, questions about the safety of being in ketosis.

In today’s post, I hope to clear up some myths and put to rest any concerns you may have about the safety of being in ketosis. As well as to encourage you to visit your doctor before embracing a keto diet.

We commonly hear, “is ketosis safe”? And if it is, is it something to pursue.

The reason we hear this question being raised often, is due to either misinformation or outdated science that is still being circulated.

In addition, there is an assumption that ketosis carries the same dangers of ketoacidosis. But there is a vast difference between the two.

Ketoacidosis Is Dangerous

Ketosacidosis is in fact a dangerous metabolic state. It’s one that occurs when individuals with type 1 diabetes and occasionally type 2 diabetics are not managing their diabetes properly.

It’s caused by a lack of insulin in the body. When insulin isn’t being produced by the body, it causes blood sugar levels to rise to very high levels and stored fat streams from fat cells.

The excessive amount of fat that is metabolized produces abnormal amounts of ketones.  When this occurs there is a combination of high blood sugar and high ketone levels.

This state is also known as DKA, when large amounts of ketone bodies in the blood cause it to become acidic. If left untreated it could even be deadly. Ketoacidosis causes ketone levels that are greater than 20 mmol/L

Ketosis Is Different From Ketoacidosis

When it comes to ketosis it’s a completely natural state that occurs when an individual adheres to a ketogenic diet and reduces their carbohydrates or abstains from food by fasting for an extended time.

It’s when their body begins to produce ketones for energy instead of glucose, because glucose is in short supply.

In a state of nutritional ketosis your blood sugar levels are normal to low and your ketone levels are between 0.5-3 mmol/L.

Ketosis is a controlled, insulin regulated process that allows for small ketones to be produced when fat is metabolized.

Is Ketosis Safe?

If you are wondering is ketosis safe or a good state to be in? This of course depends on your current state of health.

Which is why we encourage individuals to get a check-up before starting a low carb, keto diet. Not only is it important to get your doctor’s approval but in many cases medications will need to be adjusted as your health improves.

Randy and I were able to get off medications but we did so with our doctor’s approval and guidance.

Most diabetics are familiar with the term ketosis but usually only hear the negative side to it. This is because when a diabetic’s sugar levels are too high the body produces an enormous amount of ketones.

The pancreas is the organ responsible for creating the hormone insulin. Insulin is what helps the body to manage blood sugar and fat storage.

Unfortunately, when insulin is not being produced because the pancreas is too taxed, the body can no longer use glucose to fuel the cells. It also cannot store fat in the fat cells.

When this happens an individual is classified as having Type 1 diabetes and the diagnosis is usually accompanied by unexplained weight loss.

In fact, it’s this sudden weight loss that usually gets them to visit a doctor and get diagnosed.

People with Type 1 diabetes have pancreatic damage and explains why they are unable to produce insulin.

Type 1 diabetics need to be injected insulin because their pancreas can no longer produce this hormone. They can develop ketoacidosis if they are not getting the right levels of insulin.

However, ketosis is a perfectly normal metabolic process. It’s when your body switches to burning fat for fuel by breaking down fatty acids and produce ketones.

This only happens in the absence of glucose, when our carbohydrate levels are quite low.

When our bodies burn fat for fuel we produce three bi-products of fat breakdown, β-hydroxybutyrate (BHB), acetoacetate (ACA) and acetone. These bi-products are called ketones.

In a state of ketosis our liver breaks down fat, and then releases ketones into the blood to be used by the brain and organs for energy.

While on a low carb, keto diet you are basically inducing this process by cutting back intentionally on carbs. In addition, your ketone levels do not rise to dangerous levels.

Why is this?

Because ketones are water-soluble, meaning whatever excess amounts of ketones may be in your system will be eliminated through the urine naturally.

What’s more ketone levels for adults who have a functioning pancreas and whose insulin production is normal very rarely have ketone levels that go beyond 8-10 mmol/L.

What Can Cause Ketoacidosis?

One of the main reasons people ask is ketosis safe? s because of the more commonly heard  term ketoacidosis.

You can’t blame people for wondering if ketosis is safe, because it does sound familiar to ketoacidosis. In fact, even medical professionals who are not well versed in this topic get the terms confused.

The number one cause of ketoacidosis is poorly managed Type 1 and 2 diabetes. AND it is more commonly seen in Type 1 diabetics that are either not getting enough insulin or using too high of an insulin dose.

Ketoacidosis or (DKA) usually shows up initially when someone first becomes diabetic, because they have yet to introduce a blood sugar management protocol.

For this reason, a person with a high risk of develop diabetes should be under a doctor’s care.

In addition to poorly managed diabetes, a person can experience ketoacidosis for the following reasons:

  • A thyroid that is overactive
  • Starvation
  • Alcoholism
  • Pancreatitis
  • Sepsis
  • Urinary tract infections
  • Heart attack
  • Pneumonia
  • Medications that cause improper use of insulin
  • Drug abuse

Main Ketoacidosis Symptoms

  • Dehydration
  • Extreme thirst
  • Vomiting
  • Nausea and/or abdominal pain
  • Excessive urination
  • Hyperglycemia (low blood sugar)
  • Shortness of breath
  • Extreme fatigue
  • Brain fog

Individuals with diabetes or who are at a higher risk of developing the disease should visit their doctor immediately if they have any symptoms of ketoacidosis.

Note that in the case of a well-formulated keto diet individuals only produce ketone levels between 0.5-3 mmol.  This range of ketone levels is considered safe for healthy individuals. Understanding this makes the question, is ketosis even safe, a mute one.

But What Exactly Is A Ketogenic Diet?

The most traditional explanation of a ketogenic diet, is a diet that contains less than 50 grams of carbohydrates per day or 5 to 10 percent of total daily calories.

It also can have an intake of dietary fat as high as 85 percent. Another way of saying it is, that it’s a diet that has four times more fat than carbs, with protein levels managed so that 90 percent of calories are coming from fat. This is what is considered strict keto.

A ketogenic diet has been referred to by several different names including, low carb, LCHF (low carb high fat), lazy keto, and keto.

When a properly formulated ketogenic diet is maintained it forces your body into a state of metabolic ketosis. It’s not done by extreme calorie restriction but by drastically reducing your carbohydrate intake instead.

In this way a keto diet mimics fasting. Which is why Randy and I believe that combining a keto diet with our Christian faith is a powerful transformative tool.

Being in a state of therapeutic ketosis offers many health benefits that go beyond weight loss. It has many other physical and mental benefits.

Type 2 Diabetics Using Keto

Type 2 diabetes is one of the most common forms of diabetes. Accounting for almost 95% of all cases of diagnosed diabetes.

Over 29 million people in the United States alone suffer from diabetes. What’s frightening is that over a third of US adults have pre-diabetes and 90% of them are clueless to the fact.

We are facing a real diabetes crises in this country and yet most people are walking around unaware of it.
In most cases people are diagnosed when their uncontrolled sugar levels land them in the emergency room of a hospital.

Type 1 Diabetics Using A Ketogenic Diet

In the case of a Type 1 diabetics, you need to tread lightly when doing a keto diet, but it can be used as an effective tool to manage it. Once again I remind you to enlist the help of a doctor.

Dr. Richard K. Bernstein is a pioneer in using a low carb, keto diet to address Type 1 diabetes. I encourage you to visit his site for more information.

The latest study on Type 1 diabetics using a keto diet are promising. It points to how it’s helped them reduce HbA1c levels, reduce the amount of insulin used, and allowed for weight loss

 Keto Flu

Are there any downsides to being in ketosis? When an individual switches from being primarily a glucose (sugar-burner) to a ketone (fat-burner) they can sometimes temporarily experience unpleasant symptoms, such as:

  • Lethargy
  • Brain Fog
  • Mood Swings
  • Headaches
  • Tiredness

These symptoms can occur when first embarking on a ketogenic diet or after eating a high carb meal once you have been doing this diet.  This is because your body has to burn through the excess glycogen before burning fat for fuel.

Can The Keto Flu Be Avoided?

The good news is that keto flu symptoms are short-term and they can be reduced or even prevented by taking some measures.

  • Make sure you are properly hydrated: A good guide is to drink half your weight in ounces of water. Calculation: Your weight X .05= ounces of water per day
  • Use exogenous ketones: You can raise your ketones by taking them in the form of a ketone supplement. Doing so helps you get into a state of ketosis faster and thereby reduces keto flu symptoms quicker.  In this way it doesn’t rely on your diet alone to be in a state of ketosis.
  • Add more salt: A keto diet has a diuretic effect and can therefore excrete more sodium. For this reason adding high level salt in the form of Himalayan pink salt, or Celtic salt is advisable.
  • Raise your healthy fat intake: By having enough healthy fats you keep your brain properly nourished. The key is to replace the carbohydrates you eliminated with keto approved fats.
