The ketogenic diet is a popular low-carb, high-fat diet that has shown promising results for weight loss, improved blood sugar control, and various health benefits.

However, the ketogenic diet is not suitable for everyone. In this comprehensive guide, we will go over who should avoid the ketogenic diet and why.

1. People with Certain Medical Conditions

The ketogenic diet may not be safe for people with certain medical conditions, including:.

Eating Disorders

The ketogenic diet may trigger or worsen eating disorders, such as anorexia or bulimia.

Gallbladder Disease

The ketogenic diet is high in fat, which can put extra stress on the gallbladder. This can be dangerous for people with gallbladder disease or those who have had their gallbladder removed.

Pancreatitis

The high fat content of the ketogenic diet can aggravate pancreatitis, a condition where the pancreas becomes inflamed and painful.

Kidney disease

The ketogenic diet can put extra strain on the kidneys. People with kidney disease or a history of kidney stones should avoid the ketogenic diet.

2. People Taking Certain Medications

The ketogenic diet can interact with certain medications, making them less effective or causing undesirable side effects. You should speak to your doctor before starting the ketogenic diet if you take any of the following medications:.

Diabetes Medications

The ketogenic diet can lower blood sugar levels, which may require an adjustment in diabetic medication dosage. This should be done under medical supervision.

Blood Pressure Medications

The ketogenic diet can lower blood pressure, which can lead to a medication overdose. Speak to your doctor about adjusting your medication if you plan to start the ketogenic diet.

Cholesterol-Lowering Medications

The ketogenic diet can raise cholesterol levels and may interfere with cholesterol-lowering medications. Speak to your doctor before starting the ketogenic diet if you take any cholesterol-lowering medications.

3. Pregnant or Breastfeeding Women

The safety of the ketogenic diet during pregnancy and breastfeeding is not well established.

While some women may safely follow the ketogenic diet during pregnancy or breastfeeding, there is not enough research to determine the safety of this diet during these critical times.

4. Athletes and Active Individuals

The ketogenic diet may not be ideal for athletes or highly active individuals who require a lot of carbohydrates for energy. The ketogenic diet restricts carbohydrates, which can lead to decreased energy and exercise performance.

However, some athletes and active individuals have found success with the targeted ketogenic diet or the cyclical ketogenic diet, which allow for carbohydrates at certain times to provide enough energy for high-intensity exercise.

5. People with a History of Eating Disorders

The ketogenic diet may trigger or worsen eating disorders, particularly in individuals with a history of disordered eating.

Eating disorders can be life-threatening and should be treated by a healthcare professional before considering any restrictive diet.

6. Individuals with Fatty Liver Disease

The ketogenic diet can be helpful for individuals with non-alcoholic fatty liver disease (NAFLD), but it may not be safe for those with advanced liver disease or cirrhosis.

Speak to your doctor before starting the ketogenic diet if you have any liver disease.

7. People with a History of High Cholesterol Levels

The ketogenic diet can raise cholesterol levels in some people, particularly those with a history of high cholesterol levels or heart disease.

Speak to your doctor before starting the ketogenic diet if you have a history of high cholesterol levels or heart disease.

8. Those Who Struggle to Get Enough Micronutrients

The ketogenic diet restricts certain food groups, which can make it challenging to get enough micronutrients, such as vitamins and minerals. This can be particularly problematic for people who already struggle to get enough nutrients from their diet.

9. Children

The ketogenic diet may not be suitable for children, particularly those with a history of seizures. Speak to your child’s pediatrician before considering the ketogenic diet for your child.

10. Those Who Cannot Maintain the Diet Long-Term

The ketogenic diet can lead to impressive weight loss and health improvements in the short-term, but it can be challenging to maintain long-term. The ketogenic diet is a restrictive diet that requires careful planning, preparation, and adherence.

Those who cannot maintain the diet long-term may regain weight and not experience the full benefits of the diet.

The Bottom Line

The ketogenic diet is not suitable for everyone.

People with certain medical conditions, those taking certain medications, pregnant or breastfeeding women, athletes and active individuals, individuals with a history of eating disorders, those with fatty liver disease or high cholesterol levels, those who struggle to get enough micronutrients, children, and those unable to maintain the diet long-term should avoid the ketogenic diet. Speak to your doctor before starting the ketogenic diet if you have any concerns or medical conditions.
