The ketogenic diet is not just a trend—it’s a powerful lifestyle tool for improving your health, managing weight, and even reversing chronic conditions. With roots stretching back a century, keto has evolved into numerous variations, each tailored to specific needs. Whether you’re looking to lose weight, enhance athletic performance, or heal your body from the inside out, this guide will provide everything you need to know, including why starting with a 90-day carnivore reset is the ultimate way to begin your journey.

What Is the Ketogenic Diet?

The ketogenic diet is a low-carb, high-fat dietary approach that shifts your body into a metabolic state called ketosis. By drastically reducing carbohydrate intake, your body starts burning fat for fuel instead of glucose, producing ketones as a byproduct. These ketones power your brain and body efficiently, offering a range of benefits from weight loss to improved mental clarity.

First developed in the 1920s by Dr. Russell Wilder at the Mayo Clinic, keto was originally used to treat epilepsy. Case studies from institutions like Johns Hopkins have shown that ketogenic diets reduce seizure frequency by up to 50% in children with epilepsy. Today, keto has expanded far beyond its medical origins to become a mainstream solution for weight loss, metabolic health, and chronic disease management.

The Health Benefits of the Ketogenic Diet

1. Neurological Benefits

• Originally designed for epilepsy, keto reduces neuroinflammation and enhances brain function.
• Emerging evidence suggests keto’s potential in managing Alzheimer’s, Parkinson’s, and autism spectrum disorders.
• Mental health improvements are also notable, with thousands reporting reductions in anxiety, depression, and brain fog.

2. Weight Loss and Metabolic Health

• Keto promotes fat burning and suppresses appetite, making it effective for sustained weight loss.
• A 2017 meta-analysis found that ketogenic diets outperform low-fat diets in reducing body weight, triglycerides, and improving HDL cholesterol.

3. Autoimmune and Inflammatory Conditions

• The carnivore diet, a strict version of keto, has reversed autoimmune diseases like rheumatoid arthritis, lupus, and psoriasis in thousands of anecdotal cases.
• By eliminating inflammatory foods, people report relief from chronic pain and systemic inflammation.

4. Athletic Performance

• Variations like the Targeted and Cyclical Ketogenic Diets (TKD and CKD) allow athletes to optimize performance by strategically including carbohydrates.
• Athletes like Zach Bitter, a record-holding ultramarathoner, have used keto to improve endurance and recovery.

5. Mental Health

• Ketones provide a stable energy source for the brain, stabilizing mood and reducing the need for medication in conditions like bipolar disorder and depression.

The Variations of the Ketogenic Diet

The ketogenic diet isn’t one-size-fits-all. Below are the most popular variations, how to follow them, their pros and cons, and real-world case studies.

1. Standard Ketogenic Diet (SKD)

• What It Is: The classic version—75% fat, 20% protein, 5% carbs—focused on weight loss and metabolic health.
• How to Follow: Keep net carbs under 20-50g/day. Eat fatty meats, low-carb vegetables, and healthy fats.
• Pros: Simple, well-researched, ideal for beginners.
• Cons: May cause “keto flu” during adaptation.
• Case Study: A 2004 study found participants lost 12% of their body weight and improved cardiovascular markers on SKD.

2. Targeted Ketogenic Diet (TKD)

• What It Is: Includes 20-50g of carbs around workouts for high-intensity exercise.
• How to Follow: Eat fast-digesting carbs (e.g., ripe banana) 30 minutes before or after workouts.
• Pros: Boosts performance without disrupting ketosis.
• Cons: Not suitable for sedentary individuals.
• Case Study: Athletes on TKD maintained ketosis while improving workout performance.

3. Cyclical Ketogenic Diet (CKD)

• What It Is: Alternates 5-6 days of keto with 1-2 days of high-carb refeeding.
• How to Follow: Strict keto on weekdays, then eat 300-600g of carbs (e.g., rice, sweet potatoes) during refeed days.
• Pros: Improves glycogen storage and muscle recovery.
• Cons: Can disrupt ketosis temporarily.
• Case Study: Bodybuilders report better muscle growth and fat loss using CKD.

4. Carnivore Diet

• What It Is: The ultimate elimination diet—eat only animal-based foods (meat, fish, eggs).
• How to Follow: Eliminate all plant foods for 90 days to reset your body, then reintroduce foods.
• Pros: Resolves autoimmune issues, reduces inflammation, improves mental health.
• Cons: Highly restrictive; requires careful planning.
• Case Study: Mikhaila Peterson reversed severe rheumatoid arthritis and depression on carnivore.

5. Well-Formulated Ketogenic Diet (WFKD)

• What It Is: Focuses on nutrient-dense, whole foods for sustainable health.
• How to Follow: Eat fatty fish, organ meats, and leafy greens. Avoid processed keto snacks.
• Pros: Long-term health benefits; reduces nutrient deficiencies.
• Cons: Requires more effort in meal preparation.
• Case Study: Phinney and Volek’s research demonstrates WFKD’s effectiveness in reversing metabolic syndrome.

6. Therapeutic Ketogenic Diet

• What It Is: A medically supervised diet with 80-90% fat for epilepsy, Alzheimer’s, or cancer.
• How to Follow: Use MCT oil, butter, and heavy cream to achieve high fat intake.
• Pros: Proven therapeutic benefits.
• Cons: Requires medical supervision; extremely restrictive.
• Case Study: A Johns Hopkins study showed a 50% reduction in seizures in children with epilepsy.

7. High-Protein Ketogenic Diet

• What It Is: Increases protein to 30-35%, reducing fat to 60-65%.
• How to Follow: Focus on lean proteins like chicken and fish while limiting carbs.
• Pros: Preserves muscle mass; increases satiety.
• Cons: Excess protein can inhibit ketosis.
• Case Study: Fitness enthusiasts using this approach report better body composition.

Why Start with a 90-Day Carnivore Reset?

The carnivore diet is the most effective way to eliminate inflammatory foods and reset your body. By eating only animal-based foods for 90 days, you allow your gut, immune system, and mind to heal. Thousands of people report life-changing benefits, including the reversal of autoimmune conditions, mental clarity, and improved mood.

Once the 90 days are complete, you can reintroduce foods one at a time, transitioning to the keto variation that suits your needs. This N=1 experimentation helps identify which foods cause inflammation and which support your optimal health.
