The ketogenic diet, or “keto diet,” is a healthy way to eat that is low in carbs and high in fat.
A lot of research has shown that this kind of eating can help you lose weight and get healthier.
Some studies show that ketogenic diets may even help people with diabetes, cancer, epilepsy, and Alzheimer’s disease.
Here is a complete guide for people who are new to the keto diet.
What is Keto Diet?
The ketogenic diet has been in existence for an extended period of time. It first appeared in the 1920s. Initially, physicians recommended it to alleviate conditions such as diabetes and epilepsy. But today, a small number of individuals employ the ketogenic diet as a method of weight loss.
Carbohydrates, such as breads, macaroni, and potatoes, make up more than 50% of many Americans’ daily diets. The body metabolizes the glucose (sugars) present in carbohydrates to provide energy.
The objective of the keto diet is to replace glucose-rich calories with fat. The typical keto diet primarily focuses your nutrition on fatty foods. They will account for 60% to 80% of your daily caloric intake. Proteins constitute 15% to 20% of the composition. The maximum amount of carbohydrate is 50 grams. This results in a diet that is quite restrictive.
According to research, individuals who adhere to the low-carb keto diet are more likely to experience weight loss within the first three to six months than those who adhere to a more balanced diet. However, because of the significant changes that the keto diet necessitates in one’s daily diet, it is advisable to consult with a physician or nutritionist prior to commencing the diet.
Types of Keto Diet?
If you intend to initiate the keto diet, it is important to be aware that there are numerous variations. Each one concentrates on minute adjustments to the ratio of carbohydrates, protein, and lipids in your daily diet.
The keto diet encompasses the following types:
- Standard ketogenic diet (SKD). This diet is characterized by a high level of fat, moderate protein, and low carbohydrate content. In your daily diet, it typically comprises 70% fat, 20% protein, and only 10% carbohydrates.
- Cyclical ketogenic diet (CKD). This consists of increments of higher-carb “refeeds,” such as five ketogenic days followed by two high-carb days.
- Targeted ketogenic diet (TKD). This diet allows carbohydrates to be incorporated into strenuous exercise.
- High-protein ketogenic diet (HPKD). It is comparable to the SKD; however, it permits the consumption of an increased quantity of protein. On average, the composition is 60% fat, 35% protein, and 5% carbohydrates.
How do You Start a Keto Diet?
In order to initiate the keto diet, it may be necessary to eliminate certain items from your pantry and incorporate specific high-fat food sources into your daily diet.
Consult with your physician or a nutritionist to determine the most suitable course of action for you. This is especially critical if you have additional dietary restrictions, such as specific food allergies, being vegan or vegetarian, or being vegetarian. Experts can assist you in identifying substitutes or alternatives and developing a meal plan that is most appropriate for your requirements.
Before you begin altering your diet, it is important to consult your doctor or consider the following questions:
- Is the keto diet effective for treating specific health conditions?
- Is it necessary for you to reduce your weight?
- What are some of the adverse effects?
- Is it advisable to consume or maintain vitamins or supplements while adhering to a diet?
- What is the recommended duration of the keto diet?
- Should you engage in physical activity? If so, what is the amount?

Side effects
While the ketogenic diet is generally considered safe for the majority of healthy individuals, it is possible to experience some initial side effects as the body adjusts to this dietary change.
Anecdotal evidence suggests the presence of these effects, commonly known as the keto flu. According to reports from individuals following this eating regimen, these symptoms typically resolve within a few days.
Symptoms associated with the keto flu may include diarrhea, constipation, and vomiting. Additionally, some less frequently reported symptoms are:
- reduced energy and cognitive function
- increased appetite
- sleep disturbances
- nausea
- gastrointestinal discomfort
- diminished exercise performance.
What foods do I avoid on a keto diet?
You should limit foods that are high in carbohydrates.
A ketogenic diet requires the reduction or elimination of the following foods:
- Sugary foods: include soda, fruit juice, smoothies, cake, ice cream, and confectionery.
- Grains or starches: Cereal, pasta, rice, and other wheat-based products are examples of grains or carbohydrates.
- Fruit: all fruit, except for small amounts of berries such as strawberries
- Beans or Legumes: Legumes, also known as beans, include chickpeas, lentils, kidney beans, among others.

Benefits of the keto diet?
Initially, researchers developed the ketogenic diet as a treatment for neurological disorders, including epilepsy.
Recent studies have demonstrated the benefits of the diet for a diverse array of health conditions.
- Heart disease: The ketogenic diet has the potential to enhance risk factors such as blood pressure, blood sugar, HDL (good) cholesterol levels, and body fat.
- Cancer: Researchers are currently investigating the diet as an additional cancer treatment due to its potential to slow the growth of tumors.
- Alzheimer’s disease: The ketogenic diet may alleviate Alzheimer’s disease symptoms and slow its progression.
- Epilepsy: Research has demonstrated that the ketogenic diet can result in substantial seizure reductions in adolescents with epilepsy.
- Parkinson’s disease: While additional research is required, a single study discovered that the diet was effective in alleviating Parkinson’s disease symptoms.
- Polycystic ovary syndrome: It is possible that the ketogenic diet may be instrumental in treating polycystic ovary syndrome by lowering insulin levels.
- Brain injuries. Certain studies suggest that the diet may improve the outcome of traumatic brain injuries.
Are There Risks From a Keto Diet?
The ketogenic diet offers various advantages; however, adhering to it over an extended period may lead to certain adverse effects, including the following risks:
- decreased protein levels in the bloodstream
- accumulation of fat in the liver
- formation of kidney stones
- deficiencies in essential micronutrients
Doctors who prescribe sodium-glucose cotransporter 2 (SGLT2) inhibitors to manage type 2 diabetes may increase the risk of their patients developing diabetic ketoacidosis. Increased acidity in the blood characterizes this serious condition. It is advisable for these individuals to refrain from following the ketogenic diet.
Researchers are conducting ongoing research to assess the long-term safety of the ketogenic diet.
The bottom line
When adhering to the ketogenic diet, one decreases their carbohydrate consumption and substitutes it with beneficial fats. This can promote the body’s utilization of fat for energy, facilitating weight loss and potentially lowering the risk of certain health conditions. It is advisable to seek advice from a healthcare professional before committing to this diet for an extended duration, as there may be some adverse effects. Further studies are necessary to comprehend its impact on the body over the long term.
