The ketogenic diet, or keto for short, is a high-fat, moderate-protein, low-carbohydrate diet that has gained popularity as a weight loss method. The keto diet first surfaced in the 1920s as a treatment for conditions like epilepsy and diabetes. On a keto diet, the goal is to swap out glucose calories with fat. In a typical keto diet, fat will make up 60% to 80% of your daily calories, proteins will make up 15% to 20%, and carbs are restricted to no more than 50 grams.
The keto diet can be restrictive and requires careful planning. There are several types of keto diets, including the standard ketogenic diet, cyclical ketogenic diet, targeted ketogenic diet, and high-protein ketogenic diet. Each of these focuses on slight changes in the proportion of fat, protein, and carbs in your daily diet.
The keto diet has been highly effective for certain conditions, especially type 2 diabetes. One study found that the keto diet reversed diabetes in about 60% of participants and helped many lower their dependence on prescription insulin drugs.
If you're considering starting a keto diet, it's important to talk to your doctor or a nutritionist to ensure it's right for you. They can help you come up with a meal plan that suits your needs and health goals.

How to create a keto meal plan
A keto diet is a high-fat, low-carbohydrate diet that has been used to help with conditions like epilepsy and diabetes, as well as for weight loss. The goal of the keto diet is to swap out glucose calories with fat. In a typical keto diet, fat will make up around 60% to 80% of your daily calories, proteins will make up 15% to 20%, and carbs are restricted to no more than 50 grams.
- Choose keto-friendly foods: Select foods that are high in fat and low in carbs, such as meat, fish, eggs, dairy, nuts, seeds, and non-starchy vegetables.
- Plan your meals: Decide what you will eat for each meal and stick to your plan. This will help you stay within the correct macronutrient ratios and prevent hunger.
- Cook in batches: Prepare multiple servings of your meals and refrigerate or freeze the leftovers for another day. This will save you time and effort.
- Keep it simple: Opt for simple, no-cook meals or meals that require minimal preparation. For example, boiled eggs, canned fish, cheese, cold cuts, and pre-chopped veggies.
- Stock up on keto-friendly foods: Fill your kitchen with keto-friendly options so that you always have something to eat. This will also help you avoid high-carb foods.
- Read labels: Check the ingredients list and carb content of packaged foods to ensure they fit within your keto plan.
- Stay hydrated: Drink plenty of fluids, especially during the first week of your keto meal plan, to minimize symptoms of the "keto flu," which can include stomach aches, diarrhea, and trouble sleeping.
- Get enough electrolytes: Supplement with electrolytes or eat electrolyte-rich foods, such as bone broth, to help prevent keto flu symptoms.
- Consider supplements: Work with your healthcare provider to determine if you need any supplements to fill in nutritional gaps while on the keto diet.
- Adjust your activity level: Consider reducing your physical activity during the first week or two of your keto meal plan to give your body time to adjust to the new diet.
- Seek professional guidance: Consult a doctor or dietitian to ensure your keto meal plan is safe and meets your individual needs and goals.

The different types of keto diets
The ketogenic, or keto, diet is a high-fat, low-carb diet that has become a popular method worldwide for people trying to lose weight and improve their health. There are several types of keto diets, each with its own unique set of benefits and risks. Here is a detailed overview of some of the most common types of keto diets:
Standard Ketogenic Diet (SKD)
This is the most common and well-researched type of keto diet. It typically consists of 70-75% fat, 20% protein, and only 5-10% carbs. This diet has been shown to be effective for weight loss and improving blood glucose control and heart health.
Cyclical Ketogenic Diet (CKD)
The CKD involves periods of higher carb intake, such as 5 days of ketogenic eating followed by 2 days of higher carb consumption. This approach is intended for athletes who need to replenish glycogen lost during workouts.
Targeted Ketogenic Diet (TKD)
The TKD is similar to the SKD but allows for the addition of carbs around workout times. It is a compromise between the SKD and CKD, providing more flexibility for those who engage in intense physical activity.
High-Protein Ketogenic Diet
As the name suggests, this version of the keto diet includes more protein than the SKD, with a ratio of 30-35% protein, 60-65% fat, and 5% carbs. This diet is often used by bodybuilders and older individuals looking to protect muscle mass.
Calorie-Restricted Ketogenic Diet
This diet is similar to the SKD but restricts calories to a set amount. Research suggests that keto diets can be effective for weight loss, even without calorie restriction, due to the satiating effect of consuming high amounts of fat.
Lazy Keto Diet
The lazy keto diet is a more flexible approach that focuses solely on tracking carb intake, typically keeping it below 50 grams per day. This version may be suitable for those who find the strict tracking of calories, fat, and protein on the SKD too complicated.
Mediterranean Keto Diet
The Mediterranean keto diet combines the standard keto macros with the emphasis on healthy fats and unprocessed foods typically found in the Mediterranean diet. This approach may offer heart-health benefits due to the focus on monounsaturated fatty acids and omega-3s.
Keto 2.0
Keto 2.0 is a less restrictive version of the standard keto diet, allowing for more variety in carb sources, such as fruit, vegetables, beans, and whole grains. This approach may be more sustainable for those who find the strict carb limitations of the SKD challenging.
Dirty Keto
The dirty keto diet follows the same macronutrient distribution as the SKD but does not place restrictions on the sources of those macros. This means that highly processed and prepackaged meals can be included, making this a convenient option for those with busy schedules.
Clean Keto
Clean keto swings in the opposite direction of dirty keto, focusing on consuming organic and "healthy" versions of foods while still adhering to the standard keto macros. This approach may be more expensive due to the emphasis on grass-fed meats and other high-quality food items.

The benefits of a keto diet
The ketogenic diet is a high-fat, low-carb diet that has been linked to a range of health benefits. Here are some of the key advantages of following a keto diet:
- Weight loss: Research shows that keto diets are effective at promoting weight loss. They can reduce appetite and increase satiety, which can be helpful when trying to lose weight.
- Improved blood sugar and insulin levels: The keto diet can lower blood sugar and insulin levels, which may be beneficial for people with type 2 diabetes.
- Reduced abdominal fat: The keto diet can lead to a significant reduction in abdominal fat, which is associated with a decreased risk of heart disease and type 2 diabetes.
- Lowered triglycerides: Triglycerides are fat molecules that increase the risk of heart disease. The keto diet has been found to drastically reduce blood triglycerides.
- Increased 'good' HDL cholesterol: The keto diet's high-fat content leads to an increase in "good" HDL cholesterol, which is linked to improved heart health.
- Reduced blood pressure: Following a keto diet can effectively lower blood pressure, reducing the risk of heart disease, stroke, and kidney failure.
- Treatment for metabolic syndrome: Metabolic syndrome is a condition associated with an increased risk of diabetes and heart disease. The keto diet can effectively treat all five key symptoms of metabolic syndrome.
- Improved 'bad' LDL cholesterol: The keto diet increases the size of "bad" LDL cholesterol particles, reducing their harmful effects, and may also reduce the total number of LDL particles in the bloodstream.
- Beneficial for brain disorders: The keto diet has been used to treat epilepsy in children and is being studied for its potential benefits in treating other brain conditions such as Alzheimer's and Parkinson's disease.

The risks of a keto diet
The keto diet is a low-carb, high-fat diet that has gained popularity in recent years as a weight-loss method. While it may be effective for weight loss, it is not without its risks. Here are some of the dangers associated with the keto diet:
- Keto Flu: The keto diet can cause a range of flu-like symptoms, including leg cramps, digestive issues, bad breath, headaches, dizziness, fatigue, nausea, and constipation. These symptoms are caused by the body adapting to a diet very low in carbohydrates.
- Weight Regain: While the keto diet may help with initial weight loss, stopping the diet may lead to weight regain.
- Not Suitable for Everyone: The keto diet is not recommended for individuals with kidney failure, liver disease, or type 1 diabetes. It can lead to diabetes-related ketoacidosis, a dangerous condition that increases blood acidity.
- Cholesterol Impact: The keto diet is typically high in saturated fat and trans fats, which can raise "bad" LDL cholesterol and increase the risk of cardiovascular disease, heart attack, and stroke.
- Nutrient Deficiencies: The keto diet restricts fruits, grains, and legumes, which are important sources of fiber, vitamins, and minerals. This restriction may lead to deficiencies in fiber, B vitamins, calcium, vitamin D, magnesium, and phosphorus.
- Restrictive and Hard to Sustain: The keto diet is very restrictive, making it difficult to sustain in the long term. It can also affect social events as eating out becomes more challenging.
- Pregnancy and Nursing: The keto diet may not be safe for pregnant or nursing individuals.
- Liver Problems: The high-fat content of the keto diet may overload the liver and worsen existing liver conditions.
- Kidney Problems: The keto diet may increase the risk of kidney stones and can be harmful to individuals with chronic kidney disease.
- Digestive Issues and Gut Health: The keto diet's restriction of fiber-rich foods can lead to digestive issues and negative effects on gut health.
- Bone Health: The keto diet has been associated with impaired bone health and reduced bone mineral density in some studies.
- Chronic Diseases and Early Death: Some evidence suggests that the keto diet, when focused on animal-based food sources, may increase the risk of heart disease, cancer, and all-cause mortality.

Frequently asked questions
The keto diet is a high-fat, low-carbohydrate diet that has gained popularity as a weight loss method. It first surfaced in the 1920s as a way to help with conditions like epilepsy and diabetes.
On a keto diet, you eat too few carbs to support your body's energy needs. As a result, your body turns to burning your stores of body fat for fuel, producing ketones in the liver and entering a metabolic state called "ketosis."
There are several types of keto diet, including the standard ketogenic diet (SKD), the cyclical ketogenic diet (CKD), the targeted ketogenic diet (TKD), and the high-protein ketogenic diet (HPKD). Each focuses on slight changes in the proportion of fat, protein, and carbs in your daily diet.
Keto-friendly foods include full-fat dairy products, fatty fish like salmon, eggs, meat, and non-starchy, fibrous vegetables. For the 20 to 50 grams of carbs per day, choose non-starchy veggies like spinach, asparagus, and cauliflower.
Keto-friendly snacks include a good balance of healthy fats and moderate protein with low-carb content. Some options are jicama (a low-carb root vegetable), nuts, and cheese.
