Keto Side Effects: How To Minimize & Avoid The Risks

Keto Side Effects

Keto, or a ketogenic diet, is tough on your body, so there are side effects of a keto meal plan. Check out this list of mild and severe keto side effects experienced by those who follow a low-carb, high-fat diet for the first time.

Benefits of a keto diet include:

• Weight loss
• Mental clarity
• Greater energy
• Decreased cravings
• Muscle growth
• Clearer skin

Why You Experience Side Effects on the Keto Diet

Switching from a high-carbohydrate to a low-carbohydrate diet lowers your body’s blood sugar levels. When your blood sugar is low, your body turns to its stored fat to meet its energy needs. Fat gets broken down into molecules called ketones. On the keto diet, ketones become your alternative fuel source, which have been found to be more efficient than glucose since they provide more lasting energy. Keep in mind that it takes time for your body to get used to utilizing ketones as its fuel, which explains why keto side effects happen. Think of it as an adjustment phase, which is normal for anyone who tries anything new in life! The good news is that you don’t have to endure keto diet side effects – there are ways to minimize them and feel better.

Mild Side Effects of Keto Diet and Remedies

1. Frequent Urination is a common keto side effect

A common side effect of the keto diet is urinating more often as you start a keto diet. This happens because your body uses up its glycogen (stored glucose aka carbohydrates). Glycogen holds water in your body, which is why you release water by urinating. Why does it matter? Frequent urination can be a problem because it may lead to dehydration. You can also lose electrolytes in the process.

Solution:

• Keep your water intake high. Here’s a helpful tip to know your hydration status: Check the color of your urine! A clear or pale color means that you are well-hydrated. Dark urine means that you need to drink more water.

• Prevent electrolyte imbalances by eating low-carb foods that contain electrolytes such as sodium, potassium, calcium, and magnesium. Examples are salty snacks, green leafy vegetables, salmon, and cheese.

2. Sugar Cravings is a common keto side effect

Sugar cravings are going to be more intense as you drastically reduce carbs in your diet! Sugar cravings can make you feel weak and anxious as a keto diet side effect. But don’t worry, there are ways to fight these cravings.

Solution:

• Often sugar cravings result from a lack of protein and fat in your keto diet. Replace those carbs with foods that are packed with protein and healthy fats such as whole eggs, meat, nuts and seeds, and fatty fish.

• Engage in an activity that takes your mind off those sweets. Research shows that going for a short walk actually reduces sugar cravings.

• Make sure you’re getting enough fiber. When you cut out carb-heavy foods like pasta, and starchy vegetables like corn and sweet potato, you also miss out on fiber which can help curb sugar cravings. Try introducing more foods to your diet that are keto-friendly and contain fiber like spinach, broccoli, zucchini, avocado, and raspberries. You’ll find that with these foods you’ll stay fuller longer which will help conquer cravings.

3. Bad Breath “Keto Breath” – common keto side effect

Bad breath on a keto diet, also known as “keto breath,” is an expected keto side effect. Keto breath is often described as having a “metallic” or “fruity” smell to it. While keto breath is a good sign that you’ve reached ketosis, it can be bothersome to you and other people who notice.

Solution:

• It may take weeks before keto breath disappears (Up to 21 days). Meanwhile, you can reduce bad odor by drinking more water, brushing and flossing your teeth daily, and taking sugar-free breath mints.

4. Flu-Like Symptoms is a common keto side effect

You may have heard of “keto flu” but are not sure what it means. Keto flu is a keto side effect that is a collection of symptoms that kicks in on the first or second day of doing keto. Think of it as your body’s withdrawal reaction to carb restriction in your diet! These flu-like symptoms include headaches, tiredness, brain fog, sore throat, and muscle soreness.

Solution:

First of all, know that keto flu can go away in a few days.

• If you find yourself too weak to work, allow your body to rest. A good night’s sleep of at least 7 hours will reduce your symptoms.

• Increase your fat intake as well:

More dietary fats = more ketones in your body = fewer keto flu symptoms

• Supplement with MCT (medium-chain triglycerides) oil, a pure form of fat. Take one tablespoon straight up or add it to your cup of coffee.

5. Sleep issues are a common keto side effect

The ketogenic diet can interrupt your sleep and one common keto side effect is insomnia in the short term. However, we all know how much being sleep deprived can mess with your focus, energy and productivity. Sleep researchers have confirmed that inefficient sleep is not only detrimental to your health but also impairs judgement, mood and your ability to learn and retain information.

Solution:

Effective sleep comes down to a few simple practices and avoid some bad bedtime habits:

• Eating very late at night. When you eat too close to going to bed, it can cause indigestion which affects sleep quality and your ability to stay asleep. Instead, set a hard stop on your last meal and snacks. This will prevent overeating and improve your sleep.

• Exercising later in the day. When you exercise your brain releases adrenaline which stimulates your body and mind. By exercising closer to bed time it takes longer for your body to stabilize adrenaline levels which can make it hard to fall asleep. If working out is part of your daily routine, make sure it’s no later than 4 hours before you’re getting ready for bed.

• Using your phone or computer before bed. There has been extensive research done on how blue-light from our devices trick our brains into delaying the onset of melatonin (the sleep chemical your brain releases) and negatively affects quality of sleep for up to an hour once you have fallen asleep. Instead, try “night shift” on your phone or use some blue-light blocking glasses before bed. You’ll look smarter and sleep better.

Keep your room at an ideal temperature. The ideal temperature for your body to fall asleep is between 60-67 degrees fahrenheit. Put a few drops of lavender oil on your pillow. Studies have shown a link between lavender oil and sustained sleep.

6. Diarrhea is a common keto side effect

Some keto dieters may experience diarrhea. This keto side effect happens as a result of consuming more fat – which is a must on keto. Meanwhile, diarrhea can also be a side effect of consuming erythritol, a keto-friendly sweetener. Stopping diarrhea is important to prevent dehydration. And it’s never fun to get stuck in the bathroom.

Solution:

• You may need to reduce certain fats in your diet, such as MCT oil. If you take more than one tablespoon of MCT, you’re likely to get diarrhea. Give your tummy time to adjust.

• Try drinking bone broth. It’s packed with nutrients like collagen (good for muscles, skin, bones), and zinc (immune booster). It soothes your digestive system, is easy to digest, and also helps digest other foods.

7. Constipation is a keto side effect

Constipation is another digestive issues that’s caused by limited fiber in your diet. Because as we stated earlier, carbs are present in many high-fiber foods you’re familiar with such as whole grains and fruits. The good news is, constipation on the keto diet is very easy to deal with and prevent.

Solution:

• Boosting your fiber intake through keto-friendly foods like flaxseed, avocados, cauliflower, and chia seeds will make a big difference.

• Exercise after a meal, increases blood circulation which has been shown to help with constipation.

• Drinking more water. When you’re dehydrated water is pulled from your large intestine to serve other parts of the body where water is essential. This often causes constipation because it makes your stool more firm, and dry. By making sure you’re hydrated (about 10 cups a day), it makes easier for the body to pass stools.

8. Increase in Cholesterol is an uncommon keto side effect

There are people whose cholesterol levels increase on a keto diet. And because keto is high-fat, many falsely assume that it increases bad cholesterol and causes heart disease. Yes, cholesterol levels increase as a keto side effect, but one should look at specific cholesterol components. If you eat healthy fats on keto, then you should expect your good cholesterol (HDL cholesterol) to increase – which is a good thing. At the same time, your bad cholesterol (LDL cholesterol) decreases. This beneficial effect of the keto diet on cholesterol was demonstrated by a study done on obese patients.

Solution:

• If you have problems with your cholesterol despite following a clean keto diet (meaning, you choose healthy sources of fat and eat whole foods), you might want to check with your doctor to rule out medical conditions. Some medical conditions elevate cholesterol, and your diet may have nothing to do with it.

Severe Keto Side Effects of Keto Diet and Remedies

9. Vitamin Deficiency is an uncommon keto side effect

Not eating nutrient-dense, low-carb foods can increase your risk for vitamin deficiencies. Possible keto side effect deficiencies include vitamin A, B vitamins, vitamin C, and vitamin K. Keep in mind that these vitamins help with many bodily functions and processes. They give you energy (vitamin B), help form your red blood cells (vitamin B & K), repair your tissues (vitamin C), and boost your immune system (vitamin C & A)! You cannot afford to ignore them.

Solution:

• Avoid vitamin deficiencies by eating natural whole foods! Filling your keto meal plan with high-nutrient foods like steak, salmon, broccoli, spinach, cauliflower, raspberries, walnuts and almonds will ensure that you’re getting everything you need.

• However, if you don’t have a lot of available natural low-carb options, consider taking vitamin supplements.

10. Disruption of Menstrual Cycles is an uncommon keto side effect

This is one of the worst keto side effects you can experience if you cut calories. The danger in missed periods is that it affects your fertility. It even increases your risk for osteoporosis, a condition where your bones become fragile.

Solution:

• Strict calorie counting is not necessary for keto. The concept of “calories in versus calories out” does not paint the whole picture. Protein and fats make you feel fuller, and you won’t even have to worry about overeating.

• However, missed periods can also be a sign of a health problem unrelated to your diet. That’s why you should visit a doctor for a proper check-up!
