One of the most popular and effective ways to achieve weight loss and improve your health is adhering to a ketogenic diet. This high-fat, low-carb diet may involve 20% of protein, 10% of carbs, and 70% of fat. Keto dieters are usually able to consume fewer calories without feeling hungry.

The body’s cells normally use glucose as the primary fuel source, and glucose can be found on dietary carbs, such as starchy foods and sugars. The body then breaks these dietary carbs down into simple sugars and eventually uses it as fuel source or stores it in the liver and muscle as glycogen.

Without enough glucose to provide enough energy, the body begins breaking down fat stores and using glucose from triglycerides. It basically adopts an alternative strategy to meet your body’s energy needs.

The byproduct of this process is called ketones which, in small amounts, indicate that your body is breaking down fat. Elevated ketone levels can however poison the body and can lead to a condition called ketoacidosis.

How to Achieve Ketosis?

Ever wonder how to achieve ketosis? Well, basically adhering to a certain diet can help you get into ketosis. Choosing a diet that involves cutting carb intake and an extended period of fasting time is ideal.

Although starvation can be a way to achieve ketosis, it obviously is not sustainable in the long run. Thus, limiting carb intake can be the best approach to achieve ketosis.

Following a low-carbohydrate diet, such as keto diet, is key.

Ketosis is a metabolic state wherein the body uses fat and ketones instead of glucose as its main source of fuel. Many keto dieters aim to achieve weight loss by going into this metabolic state.

But how will you know whether or not you’ve reached the ketosis state? In this article, we will give you 11 positive and negative ketosis symptoms.

Ketosis Symptoms

1. Weight loss

The ketogenic diets are highly effective when it comes to losing weight.

In fact, several weight loss studies have shown that keto dieters are likely to experience both short- and long-term weight loss.

Some people on a keto diet may experience fast weight loss during the first week. These are primarily stored carbs and water being used up, and not fat loss.

Sticking to the diet and remaining in a calorie deficit can cause you to consistently lose body fat after the initial water weight drop.

2. Increased energy and improved focus

Feeling tired and sick and experiencing brain fog are not uncommon for people who are just starting out with a very low-carb diet. These symptoms are mostly referred to as the keto flu or low-carb flu.

But long-term keto dieters often report increased energy and improved focus.

As you begin with any low-carb diet, your body learns to adopt an alternative strategy for it to have an alternative fuel source. Instead of burning carbs, your body learns to burn more fat for fuel.

Getting into ketosis allows a large part of your brain to start burning ketones instead of glucose, which can take a few days or even weeks before it starts to work properly.

Ketones, having been tested in a medical setting to treat neurological conditions and diseases such as memory loss and concussion, are an extremely powerful fuel source for the brain.

Thus, it’s not surprising that long-term keto dieters often experience improved brain function and increased clarity.

What’s more, eliminating carbs in your diet helps control and stabilize the levels of your blood sugar, which may further improve brain function and increase focus.

3. Bad breath

Having a bad breath is also not uncommon when you reach full ketosis. In fact, many keto and Atkins dieters report having a breath that takes on a fruity smell. This is a result of elevated ketone levels; there’s a ketone called acetone that exits in your breath and urine.

Having a bad breath is absolutely less than ideal for your social life, but it can be a positive sign that you’ve reached the ketosis state. To solve the issue, many people on a keto diet either use sugar-free gum or brush their teeth several times a day.

Don’t forget to check the label for carbs if you wish to use gum, sugar-free drinks, or any other sugar-free alternatives.

4. Elevated ketones in the breath or urine

A breath analyzer can measure blood ketone levels by monitoring acetone, which is one of the three main ketones that are present in your blood when you’re in a ketosis state.

Breath analyzers are shown to give fairly accurate results, although less accurate as compared to the blood monitor method.

Using special indicator strips is also another good method to measure the presence of ketones in your urine every day. This can be a quick and cheap method to assess your ketone levels daily by measuring ketone excretion through the urine.

5. Increased ketones in the blood

An increased ketones in the blood and a reduction in blood sugar levels are hallmarks of a keto diet. As you go along with your keto diet, your body will start to burn fat and ketones as the main source of fuel.

Using a specialized meter to measure your blood ketone levels is probably the most accurate and reliable method to measure ketosis. This specialized meter calculates the amount of beta-hydroxybutyrate (BHB), one of the primary ketones present in the bloodstream, to measure your ketone levels.

Some experts on the ketogenic diet say that blood ketones ranging from 0.5–3.0 mmol/L are considered nutritional ketosis.

Measuring ketones in the blood is usually used in most research studies because it is known to be the most accurate way of testing. It’s just that it requires a small pinprick to draw blood from your finger—that’s one of the downsides of this method though.

In addition, test kits for this method can be costly. That is why most people only perform one test either every week or every other week. If you wish to try testing your ketones using this method, there are a range of good selections available for you online.

6. Appetite suppression

Most keto dieters experience reduced hunger, but the science behind this is still being investigated.

However, it’s been suggested that appetite suppression may be caused by an increased vegetable and protein intake, together with modifications to the hunger hormones of the body.

Added to that, the ketones themselves can also affect your brain to suppress appetite.

7. Short-term fatigue

New keto dieters may find the initial switch to low-carb, moderate-protein, and fat-rich diet challenging and can even be a big issue for them.

In fact, some people may even quit the diet before getting into full ketosis, leaving them to miss the many long-term benefits of the keto diet.

It’s natural for new keto dieters to experience these side effects; their body will eventually adapt to a new different system.

Don’t expect your transition into your new diet to happen overnight. It generally takes a week or even a month before you get into full ketosis.

If you experience fatigue during the initial switch, you can take electrolyte supplements.

The elimination of processed food that may contain added salt as well as the rapid reduction in your body’s water content may cause you to lose electrolytes.

8. Short-term reduced performance

Eliminating carbs in your diet may lead to general tiredness at first. You may experience an initial decrease in your daily exercise performance. This is primarily due to the reduction in your muscles’ glycogen stores, which provide the main fuel source for all forms of intense workouts or activities.

Many keto dieters report that their normal performance gets back after several weeks on the diet. A keto diet may even be beneficial for certain types of ultra-endurance sports and activities.

What’s more, this diet can potentially lead to increased ability to burn more fat during workouts.

A famous study demonstrated that athletes who switched to a keto diet burned more fat (as much as 230%) when they exercised as compared to athletes who did not follow a keto diet.

9. Insomnia

Another big issue for new keto dieters is sleep, especially when they’re just starting out with the diet.

A lot of people report waking up at night after drastically reducing carb-intake. This, however, usually improves in the long run. In fact, many long-term keto dieters reported having a better sleep quality when they switched to a keto diet.

10. Digestive issues

Considering the fact that a keto diet involves changing the types of food you eat, it’s not uncommon for you to experience some digestive issues, such as diarrhea and constipation, in the beginning.

While some of these digestive issues go away after the transition period, it’s highly important that you are mindful of the different foods that may have caused digestive issues.

Also, make sure to drink plenty of water and eat plenty of healthy low-carb, fiber-rich veggies. There are a lot of keto-related articles online to guide you on what foods to eat and what not when on a keto diet.

11. Frequent Urination

Frequent urination is also one of the signs of ketosis.

Eliminating glycogen stores can pull huge amounts of water out of your muscles. In addition, the kidneys tend to release more fluid while you are on ketosis.

Thus, increasing your fluid intake when starting a keto diet is highly recommended so as to help counteract dehydration.

Conclusion

There are absolutely many different positive and negative signs and symptoms to help you determine whether or not you’re getting into full ketosis, such as weight loss, increased energy and improved focus, bad breath, elevated ketones in the breath or urine, increased ketones in the blood, appetite suppression, short-term fatigue, short-term reduced performance, insomnia, digestive issues, and frequent urination

But consistently following the guidelines of a keto diet should help you get into the ketosis state. Monitoring ketone levels in your breath, urine, and blood on a weekly basis will absolutely give you a more accurate assessment.

But if you’re enjoying your keto diet, seeing the health benefits, losing weight, and feeling healthier, you need not be obsessed over your ketone levels.
