The ketogenic diet, originally conceived as a treatment for epilepsy in children, has gained popularity for its potential benefits in various medical conditions and for weight loss. This article delves into the principles of the ketogenic diet, its applications, and how a keto calculator, particularly the Ankerl keto calculator, can aid in its implementation.
What is the Ketogenic Diet?
A ketogenic diet is characterized by a high intake of fats, a low intake of carbohydrates, and a moderate amount of protein. The primary goal of this diet is to shift the body's metabolic state from using glucose (derived from carbohydrates) as its primary fuel source to using ketones (derived from fats). When carbohydrate intake is restricted, the body converts fat into ketones, which then serve as an alternative energy source. In a state of ketosis, the body preferentially utilizes ketones over glucose.
Restoration Healthcare, for instance, suggests ketogenic diets for managing medical conditions such as Lyme disease, diabetes, early-onset Alzheimer's, and even cancer. The diet shares similarities with a modified Atkins diet, emphasizing the consumption of vegetables, fats, and proteins while limiting carbohydrates, especially those found in wheat, starch, and certain fruits.
Macronutrient Ratios in a Ketogenic Diet
Typically, a ketogenic diet comprises approximately 70% of daily caloric intake from fats, 25% from protein, and only 5% from carbohydrates. Determining net carbs involves subtracting the amount of fiber per serving from the total carbohydrates per serving listed on a nutrition label. When following this diet, it's advisable to prioritize dark green vegetables like romaine lettuce, broccoli, asparagus, Brussels sprouts, and cauliflower.
The Importance of Planning and Keto Calculators
Adhering to a ketogenic diet requires meticulous planning, including creating a grocery list that aligns with the specified protein/fat/carb percentages. Utilizing a ketogenic calculator is highly recommended to accurately measure the nutritional needs while on the diet.

Ketogenic Diet for Epilepsy: A Historical Perspective
The ketogenic diet has a long history in treating intractable epilepsy. Ancient Greek physicians observed that fasting could alleviate certain types of refractory epilepsies. Although drugs like phenytoin and sodium valproate overshadowed the ketogenic diet in the early 20th century, it experienced a resurgence, partly due to the efforts of Hollywood producer Jim Abrahams, whose son's epilepsy was successfully managed with the diet.
Ketogenic vs. Modified Atkins Diet (MAD)
The ketogenic diet is prescribed based on a ratio of grams of fat to the combined grams of carbohydrate and protein, which determines the degree of ketosis (typically 3:1- 4:1). While conceptually similar to the Atkins diet, the ketogenic diet is more calorie-controlled, requiring precise measurement of all food according to a registered dietitian's prescription. The modified Atkins diet (MAD) is a less strict alternative suitable for some individuals with epilepsy.
How the Ketogenic Diet Works for Seizure Control
The exact mechanism by which the ketogenic diet reduces seizures is not fully understood. Normally, the brain relies on glucose for energy. However, during ketosis, the body shifts to using fat as its primary energy source. The liver breaks down fats into ketone bodies, which circulate in the blood and are excreted in urine. The elevated ketone levels in the blood are believed to reduce seizure frequency.
Target Population and Success Rates
The ketogenic diet is more commonly used in children, while the MAD is suitable for both children and adults. It has also shown promise in managing other disorders like tuberous sclerosis complex, a genetic disorder characterized by non-malignant tumors in the brain and other organs. The success rate of the diet is measured by seizure freedom or a decrease in seizure frequency, with similar rates for both the ketogenic diet and the MAD.
Adverse Reactions and Supplementation
Short-term side effects during the initial phase of the diet may include dehydration, hypoglycemia, vomiting, and acidosis. Potential long-term side effects include constipation, stunted growth, vitamin and mineral deficiencies, hyperlipidemia, and kidney stones. Therefore, vitamin and mineral supplements are often necessary.

Resources for Recipes and Practical Tips
Numerous online resources offer recipes and practical tips for individuals following the ketogenic diet.
Contraindications
The ketogenic diet is not suitable for everyone. It is contraindicated in patients taking medications that interfere with carbohydrate metabolism.
Implementation and Practical Considerations
The diet is typically initiated through an outpatient family meeting involving a dietitian and epileptologist. This is followed by an inpatient admission to an Epilepsy Monitoring Unit for 3-5 days, along with blood work before starting the diet.
The Role of Medical Professionals
Successful implementation of the ketogenic diet requires a concerted effort from various medical professionals.
Long-Term Management and Support
While the ketogenic diet may help some individuals reduce or eliminate anti-epileptic drugs (AEDs), this is not always the case. Support groups like the Yahoo keto group provide a platform for parents, family members, and patients to connect and learn from each other's experiences.

Ankerl Keto Calculator
The Ankerl keto calculator is a tool designed to assist individuals in determining their macronutrient needs for a ketogenic diet. It takes into account factors such as age, activity level, and target weight to calculate the appropriate daily intake of fat, protein, and carbohydrates.
Visual Body Fat Charts
Visual body fat charts can be used to estimate personal body fat percentage for use with the keto calculator.
LCHF Diet and its Benefits
The low carb high fat / ketogenic diet has a weight loss effect and many other potential benefits are often overlooked. In April 2012 an article “The Ketogenic Diet as a Treatment Paradigm for Diverse Neurological Disorders” was published that nicely summarizes what’s currently know about the effects a ketogenic diet has on multiple neurological problems.
Mobile Compatibility
Almost half of users access keto calculators from mobile devices, making it essential for these tools to be mobile-friendly.
User Demographics
Data indicates that the majority of users are between 25-34 years old, with a significant proportion being female.
Practical Tips for Implementing a Ketogenic Diet
Vegetables
Consume vegetables with meals, especially when using fats like coconut oil.
Carb Restriction
Experiment to determine the level of carb restriction that works best for individual needs. Consider the trade-off between mental sharpness and immediate gratification from consuming carbohydrates.
Transitioning to a Fat-Fueled State
Gradually transition to a low-carb diet to allow the body to adapt. One approach is to avoid combining starch and protein in the same meal.
Fat Consumption
Aim for at least 70% of daily calories from fat. Use a keto calculator to determine the appropriate calorie intake based on individual factors. Incorporate sources like coconut oil, butter, olive oil, avocados, peanut butter, and peanuts.
Coconut Oil
Coconut oil is a versatile fat source that can be added to meals and beverages.
