This also means that the fats in your body are not needed for energy and so, are stored. However, when you lower your intake of carbohydrates, your body is taken into a state which is known as ketosis.

What is Ketosis?



Ketosis is a natural process in which the body begins to help a human being survive when there is a low intake of food. When the body is in this state, the body produces ketones from the breakdown of the liver.

A properly handled keto diet would usually compel your body to go into a metabolic state and this is a result of a very low intake of carbohydrates. Naturally, when you take in a lot of fats and starve yourself of carbohydrates, your body starts to burn ketones which serves as the primary source of energy.

How to Know If You Are In Ketosis

You can use your blood strips or urine to check if you are in ketosis. However, blood strips can be expensive and urine strips may not be exactly accurate. Therefore, you should pay attention to the following symptoms;

1. Bad breath; ketone contains a body called acetone which to some extent, excretes in the breath. This smell is usually temporary and will go away soon. However, if you detect that unusual bad breath that reminds you of the sharp smell of overripe fruit, it is a symptom that you are in ketosis.

2. Higher levels of energy and reduced hunger; natural, as you enter the ketosis, you will start to experience higher levels of energy as well as a reduction in the levels of hunger.

3. More urination; keto is naturally a diuretic which means you will find yourself urinating more. When you observe that this is happening, it may be proof that you are in ketosis.

4. Dry mouth; one effect of increased urination is a dry mouth. You will, therefore, experience dry mouth a lot if you have entered ketosis and as you begin to urinate more. It is important, therefore, that you drink a lot of water during this period in order to replenish your electrolytes.

Is Ketogenic Diet Healthy?

Yes. The ketogenic diet is very healthy. As a matter of fact, it comes with lots and lots of health benefits which we have already looked at. Even though this diet comes with a few side effects, it comes with a lot more health benefits ranging from providing more energy to helping with weight loss and controlling blood sugar. In all, the ketogenic diet is a very healthy diet.

Ketogenic Diet Side Effects

Even though a ketogenic diet as we have already seen, is a very healthy diet, it comes with quite a number of side effects which most of the time, are a result of dehydration. It is, therefore, advisable to drink so much water during this period in order to prevent dehydration and avoid some of these side effects.

Here are some of the side effects of a keto diet;

1. Heart palpitations; you may notice, as you transition to keto, that your heart beats harder and faster. This is quite normal so you do not really have to worry about it. Take lots of fluid and enough salt to prevent it from persisting.

2. Constipation; this is something else you may notice as you transition to keto and it is mostly due to dehydration. Simply increase your intake of water and eat more vegetables that contain fiber. If this does not work, a probiotic or psyllium husk powder will be of great help.

3. Lower levels of physical performance; when you have just started taking a keto diet, you will likely notice limitations in your physical performance. However, this is just your body adapting to the diet. As you continue with the diet and your body gets used to it, this side effect will go away and your strength and persistence will get back to normal again.

4. Cramps; you will also notice that you are having cramps especially in your legs. But do not worry, this is only a minor thing. Just ensure that you drink a lot of water and eat enough salt in your food.

5. Hair loss; this is a very rare side effect of the keto diet but it could happen in the first five months of using the keto diet. You can cut down on this by making sure to get at least eight hours every night and doing too much restriction on calories.

6. Indigestion; this is another side effect of transitioning to the keto diet. Even though this diet can actually help to eliminate indigestion, you may experience some indigestion in the beginning. You may have to reduce the amount of fat you take at the beginning and then increase it as time goes on.

What is Keto Flu?

Keto flu is experienced by many people who are newly transitioning to the keto diet. However, this would mostly go away after a few days. You can also minimize this or completely eliminate it.

In the beginning, you may feel discomforts which would include cramps, headache, fatigue, and nausea among many other things. Keto flu happens for a number of reasons the two most primary of which are;

1. The diuretic nature of keto; because of this, you will find that you need to urinate more often which will lead to you losing water as well as electrolytes from your body. Increase your intake of water to fight this. You can also take a bouillon cube or Powerade Zero. These will help to replace the electrolytes and water you have lost.

2. The transition process; your body is already configured to take in higher carbs and lower fat. However, because you are transitioning, your brain may not have enough energy which can lead to effects like nausea, grogginess, and headaches. To help minimize this, you can make your reduction of carb intake a gradual process.

Replacing electrolytes and increasing your intake of water should go a long way to combat keto flu.
