Why am I sweating more on keto?

Sweating is a natural process of the body that helps cool us down. The keto diet can cause you to sweat more because your body’s fuel source has changed from glucose (carbohydrates) to fat and protein.


This change in fuel causes an increase in the amount of energy needed by your cells, leading to sweating. 

Your body is going to be adjusting to the keto diet in many ways. One of those things may include sweating more than you typically do. There are a few reasons this could happen, and we’ll go over them now!

The body stores around four times the amount of water on a carb-based diet per gram of carbohydrate. When you get into keto and stop eating carbs, this ratio changes to 1:4. The result is that someone might sweat or urinate more than normal while adjusting to keto.

With a regular diet, you don’t limit your carbohydrate intake. And according to some studies, one gram of carbohydrate that the body absorbs can store 4 grams of water.

The keto diet makes you eat fewer carbs. Therefore, in many ways, your body will remove stored water. Sweating is one of those ways.

Besides, the keto diet also helps you burn a large number of xenobiotics. And like a cycle, combustion produces energy, and energy has heat; heat makes you sweat.

How are ketones excreted in our breath?

Breath acetone or isopropyl alcohol.

You may sweat more because your body adjusts to the dramatic shift of metabolic processes (burning fat and protein instead of carbohydrates). This can result in an increased need for water, which will be excreted through the skin and vaporized by sweat. 

According to: ResearchGate

Your breath may smell like acetone (or isopropyl alcohol) more than usual since ketones are present in higher concentrations on keto and are being excreted from the lungs along with carbon dioxide via your breath.

So don’t worry, sweating and frequent urination are common symptoms in the early stages of ketosis.

This is caused by an increase in acetone, a product that’s created when fat cells break down into smaller molecules called fatty acids. When your body becomes accustomed to changes in diet or exercise routines, these symptoms will typically decrease as well!

What is ketosis and why does it mean to you over sweating?

I’ll help you quickly understand what ketosis is and why it makes you sweat more.

Then in the next part, I will show you how to prevent this situation.

Ketosis is a metabolic process in which fat cells break down into smaller molecules called fatty acids.

As I mentioned below, a person on the keto diet will excrete more of these compounds in their breath – including acetone or isopropyl alcohol – and will have an increase in sweating.

Why does ketosis make you sweat more?

This is because you have a higher level of ketones in the blood, which interferes with your body’s ability to cool itself by sweating.

The reason ketosis makes you sweat more is that when there are greater concentrations of ketones in your bloodstream, it will make it harder for your body to cool down, leading to sweating.

Another answer can be that ketosis causes more fatty acids to enter your sweat glands which will cause sweating too.

How to test if you are in ketosis?

My advice is not to make emotional conclusions about whether or not your body is in ketosis.

To test if you are in ketosis, check your urine for ketones with a simple at-home strip using a ketone strip test.

These products are available online and in your local pharmacies for around $1. If you’re serious about telling if you’re in ketosis or not, invest a couple of dollars and buy one now.

If you want to check your ketone levels seriously, I recommend using a different test. Using a blood-ketone meter is the most rigorous way to track your ketone levels & it is considered the gold standard in all keto research to check your ketosis status.

What to do when sweating on the Keto diet?

These symptoms will disappear as the body get used to ketosis. Even excessive sweating will subside over time. But, you also refer to the following ways to minimize sweating.

To stop sweating more on keto, here are 5 tips I have used & guided many people to improve the above situation:

Tips 1 – Avoid spicy foods

Spicy foods may cause sweating or hyperhidrosis. Chili peppers are low in carbs, making them ideal for use in the keto diet. However, the truth is that you need to avoid chili peppers and spicy foods in general. The reason is that these foods will make you sweat a lot.

Our bodies react to spicy foods with sweat to release some of the heat that these foods create.

Avoiding spicy foods can help reduce sweating.

Tips 2 – Wear more comfortable clothing

Comfortable clothes with sweat-wicking materials don’t make you sweat less. However, suitable clothing will help keep you comfortable in ketosis.

People should wear light clothing made of fabric so their sweat can evaporate quickly.

Tips 3 – Reduce daily caffeine consumption

Coffee is one of the best daily drinks for most of us. However, in ketosis, caffeine can dehydrate us quickly and cause excessive amounts of sweat.

Cutting back on caffeine means you need to kick the habit of starting your day with a cup of coffee. However, in terms of caffeine’s diuretic properties, you should consider this trade-off.

You could try to replace coffee with green tea to reduce sweating on a keto diet.

Tips 4 – Adding Supplements and Replenish your Electrolytes

This is the best option to recover the electrolytes as soon as they are lost through sweating. 

You can add supplements such as SaltStick Caps which are electrolyte capsules designed to be palatable while allowing for the absorption of electrolytes.

When sweating more on a keto diet, you’re losing vital moisture for your hydration and electrolytes like sodium, potassium, calcium, and magnesium.

To stop sweating more on keto, I like to supplement with a few different options relatively inexpensive from Amazon.

Tips 5 – Drink enough water, not over

Drinking too much water will make your body sweat more. That’s a natural thing. You can use electrolytes to replace water. This will help balance the amount of water in the body.

Other Ketosis Symptoms You May Notice

Ketosis is the metabolic state when you eat and drink on a keto diet. Ketosis is quite complicated. However, you can recognize that the body is in this state with the following 5 signs:

Feeling more focus

The keto diet causes the brain to burn large amounts of ketones instead of glucose. In some clinical trials, ketones may be used to treat brain diseases. Ketones can help improve the brain, thereby increasing the ability to concentrate effectively.

Feeling more focused also comes from consuming fewer carbs. This helps stabilize blood sugar levels, leading to better brain function.

Therefore, it is not surprising that you will feel more focused and alert when changing your diet.

Increased heart rate

Consuming fewer carbs with the keto diet leaves the body dehydrated and salt-deprived. This deficiency can increase the risk of atrial fibrillation and arrhythmia. If you never have cardiovascular disease, the increase in heart rate will not be too serious.

Dry mouth

As you probably know, dry mouth is one of the common symptoms of keto diet therapy. The cause of this condition is quite simple. 

Essentially, the keto diet allows you to increase the amount of fat in each meal by up to 80 percent and deeply reduce the number of carbs to nearly 50 grams per day. 

This inadvertently affects the transfer of hydrate in the body. From there, you will always feel a dry mouth early in the morning.

Potential digestive issues

Changing the foods you eat will change the way your digestive tract works. Problems such as constipation or diarrhea will appear during the early stages of ketosis.

Following the keto diet doesn’t mean your food intake is inadequate. To minimize problems related to the digestive system, you need to slowly adjust your diet, paying attention to ensuring enough nutrients.

The weight started to drop significantly

In just the first few weeks, when the body is in the phase of ketosis, your weight will have a noticeable change. This is due to your body using up stored carbs and water.

If you still adhere to an appropriate diet in the following weeks, weight control will not be too difficult.

How to fixing Night Sweats and Fatigue on keto?

Keto sweating is annoying, especially at night.

Night sweat is a common problem that can happen as you enter ketosis. There are many reasons why this may occur, including dehydration, the development of kidney stones in the Kidney, an infection caused by bacteria or fungus, or be related to menstrual periods. 

Another reason could be your need for electrolytes which go hand-in-hand with the keto diet, causing night sweats and fatigue.

To prevent these symptoms from worsening and leading to stomach problems such as indigestion. It is important to drink enough fluids to stay hydrated while paying attention not to over-hydrate because drinking too much will lead back to more sweating at night!

Final Thoughts

“Why am I sweating more on keto?” This is a question many people have when starting a carb-restricted diet. With the information I provide above, you must have had valuable tips for this problem.

If you’ve been on the keto diet for some time and are noticing more night sweats or fatigue, there may be other underlying factors that need to be addressed. It could be a lack of electrolytes in your system, inflammation, dehydration, etc.

As a final piece of advice, you should talk to your doctor if these symptoms persist so they can help you figure out what is going wrong with your body. Because, as mentioned in the article, you only sweat a lot in the early stages of ketosis.
