Who Shouldn’t Follow a Keto Diet?

The ketogenic diet has many health risks, and some people should not try it. For example, people with kidney disease or other conditions should avoid it. Pregnant women and people with type 1 diabetes should also avoid it. People who have had their gallbladder removed or suffer from liver or pancreatic problems should also avoid it.

The keto diet involves consuming large amounts of fat. The average daily intake is about 60% from fat and only 10% from carbohydrates. Because of the high fat content, the keto diet can cause some uncomfortable side effects.

Some studies suggest that people who are overweight or obese should not follow a ketogenic diet. This is because dieting is not a cure for weight loss. Instead, it is only a temporary solution to obesity.

Here are some people who should not follow a keto diet.

Keto Diet: Is It Right for You?

Although it has several benefits, a ketogenic diet may not be right for everyone. For example, people with type 1 diabetes are not recommended to try it because they have a higher risk of developing diabetic ketoacidosis. This condition is a serious complication of diabetes and can lead to dehydration and acidic blood.

People with type 2 diabetes, on the other hand, can benefit from this diet because it can increase insulin sensitivity and help them lose weight. As a result, it’s important to talk to your health care provider before trying the keto diet.

Who Should Avoid the Keto Diet?

People with certain health conditions or eating disorders should avoid the keto diet. The diet is restrictive in nature and can worsen an existing condition.

People dealing with an eating disorder

A Keto diet can be dangerous for people dealing with an eating disorder. It can cause nutritional deficiencies as well as kidney and liver problems. In addition, it can increase the levels of “bad” cholesterol, which can increase the risk of heart disease. The extreme restriction of this diet can worsen binge eating behaviors. It’s best to follow a diet that encourages you to eat fewer calories to avoid overeating.


Children under 18 years of age

Children under 18 should avoid ketogenic diets. A ketogenic diet can lead to nutritional deficiencies, which can be harmful to children. This diet changes the body’s energy source from carbohydrates to fat. Children’s bodies need carbohydrates to fuel their physical and mental activities, but this diet limits their carbohydrate intake to 20-30 grams per day. This can lead to a lack of energy and decreased appetite.

People with low weight

The keto diet is not recommended for underweight people, but it is safe for obese people. People who are underweight should seek medical advice before starting a ketogenic diet. This is a low-carb diet that reduces carbohydrate intake and increases satiety. It also reduces appetite and the risk of overeating. People who are underweight experience extreme side effects if they follow the keto diet.

People with diabetes on insulin

A diabetic taking insulin should not attempt a keto diet. People with diabetes are especially vulnerable to ketoacidosis, a condition in which the body cannot produce insulin. Because insulin and oral diabetes medications lower blood sugar, restricting carbohydrates in your daily calorie intake can lead to low blood sugar and hypoglycemia. Therefore, people with diabetes who take insulin should check with their doctors before starting a keto diet.

People taking metformin or other medications

If you take metformin, it may be important to consult a medical professional before starting a keto diet. This medication belongs to the biguanide class and works to lower blood sugar levels. It also inhibits the production of glucose in the liver. This can lead to an increase in lactate, a compound of lactic acid.

Pregnant and lactating women

The Keto diet is not suitable for pregnant or lactating women. It is best for these women to focus on a nutrient-dense, high-quality diet without refined sugars. They should also be aware of hunger cues. While the keto diet may sound appealing to some, it is not safe for pregnant or breastfeeding women. One study showed that mice that were on the keto diet during lactation developed ketoacidosis, which causes acid to build up in the blood.

People with Kidney Disorders

The Keto diet is not recommended for people with kidney disease, as it can make their condition worse. People with CKD should follow a low-protein diet to prevent deterioration of kidney function. The diet also restricts carbohydrates, which can make it difficult for people with kidney disease to get enough fiber.

People recovering from surgery

The keto diet is not a good idea for anyone recovering from surgery. While it may be tempting to eat a high-fat diet immediately after surgery, it’s best to wait at least four months after the procedure. To help your body heal properly, you need to follow a low-fat diet.


The ketogenic diet has numerous health risks and may be unsuitable for vegans. It is high in fat and can damage the liver in the long term. A classic vegan diet includes whole grains, nuts, seeds, legumes and root vegetables. These foods contain a lot of carbohydrates. A ketogenic diet eliminates these foods, which can lead to a nutritional deficiency.


Why Is The Keto Diet Not For Everyone?

While keto can help you burn fat more efficiently and lose weight, it’s not for everyone. For one thing, it takes a lot of effort to stay in ketosis. Also, it doesn’t allow you to consume sugar, so most no-carb sugar substitutes won’t work.

In addition, this diet can cause some side effects, such as high cholesterol and kidney problems. For these reasons, you should not start a ketogenic diet if you have a history of heart disease or blood sugar problems.

It’s also impossible to get enough nutrients on a no-carb keto diet. Some people may not tolerate the high levels of saturated fat in the ketogenic diet. For these reasons, it is not the best diet for everyone.
