Ketogenic Diet

High-fat, low-carb eating for metabolic transformation

The ketogenic diet shifts your metabolism to burn fat instead of carbohydrates, producing ketones for stable energy, enhanced mental clarity, and effective weight management.

What is the Ketogenic Diet?

The ketogenic diet is a high-fat, moderate-protein, very low-carbohydrate eating approach that shifts your body's primary fuel source from glucose (carbohydrates) to ketones (produced from fat).

When carbohydrate intake drops below approximately 50 grams per day, the liver begins converting fatty acids into ketone bodies — acetoacetate, beta-hydroxybutyrate, and acetone. These ketones become the primary energy source for your brain and body, a metabolic state called ketosis.

Originally developed in the 1920s to treat epilepsy in children, the ketogenic diet has since been studied extensively for weight loss, type 2 diabetes management, neurological conditions, and metabolic health optimization.

Did You Know?

Your brain can derive up to 75% of its energy from ketones when fully keto-adapted. Many people report enhanced mental clarity and focus, which is why executives and biohackers have embraced keto for cognitive performance.

How the Keto Diet Works

1 Carbohydrate Restriction

By limiting carbs to 20-50g daily, you deplete glycogen stores in your liver and muscles. This typically takes 2-4 days depending on activity level.

2 Fat Adaptation Begins

As glucose becomes scarce, your liver ramps up ketone production. The first 1-2 weeks involve metabolic adaptation, sometimes called the "keto flu" as your body adjusts.

3 Ketosis Achieved

Blood ketone levels reach 0.5-3.0 mmol/L, indicating nutritional ketosis. Your body is now efficiently burning fat for fuel, appetite naturally decreases, and energy stabilizes.

4 Full Keto-Adaptation

After 3-6 weeks, your mitochondria have upregulated enzymes for optimal ketone utilization. Exercise performance returns, mental clarity peaks, and the benefits fully manifest.

Science-Backed Benefits

⚖️

Weight Loss

Multiple meta-analyses show keto produces greater weight loss than low-fat diets, particularly in the first 6 months. Reduced appetite from ketosis drives a natural caloric deficit.

Blood Sugar Control

Dramatically improves insulin sensitivity and HbA1c levels. Some type 2 diabetics have reduced or eliminated medication under medical supervision.

Mental Clarity

Ketones are a more efficient fuel for the brain than glucose. Many experience reduced brain fog, improved focus, and stable mood without energy crashes.

Reduced Inflammation

Beta-hydroxybutyrate (BHB) has been shown to reduce inflammatory markers including CRP and IL-6, potentially benefiting autoimmune conditions and chronic pain.

Getting Started: Your First Week

Clear Out Your Pantry

Remove temptations: bread, pasta, cereals, sugary snacks, and seed oils. Stock up on keto staples to set yourself up for success.

Calculate Your Macros

Aim for 70-75% fat, 20-25% protein, and 5-10% carbs. Most people stay under 20-50g net carbs daily. Track for the first few weeks.

Prioritize Electrolytes

Keto causes water and electrolyte loss. Supplement sodium (salt your food liberally), potassium, and magnesium to prevent "keto flu" symptoms.

Stay Hydrated

Drink plenty of water, bone broth, and unsweetened tea. Dehydration is common in the first week as glycogen (which holds water) depletes.

Be Patient with Adaptation

The first 1-2 weeks may feel challenging. Energy may dip before it surges. Full keto-adaptation takes 3-6 weeks — the benefits compound over time.

🩺

"The ketogenic diet is not just about weight loss — it's about metabolic health. When you reduce your dependence on glucose and become metabolically flexible, you unlock a level of energy and mental clarity most people have never experienced."

— Dr. Eric Berg, DC, Ketogenic Diet Expert

Frequently Asked Questions

Is the ketogenic diet safe long-term? ▼

Research suggests keto is safe for most healthy adults. Studies have followed participants for up to 2 years without adverse effects. However, those with kidney disease, liver disease, or certain metabolic conditions should consult a doctor before starting.

What is the "keto flu" and how do I avoid it? ▼

Keto flu refers to temporary symptoms (fatigue, headaches, brain fog) as your body adapts. Prevent it by staying hydrated, consuming adequate salt (5-7g daily), and supplementing magnesium and potassium. Symptoms typically resolve within 1-2 weeks.

Can I exercise on keto? ▼

Yes! While high-intensity performance may temporarily dip during adaptation, endurance activities often improve on keto. After full adaptation (3-6 weeks), many athletes report excellent performance. Targeted or cyclical keto variants allow strategic carb timing for intense training.

How do I know if I'm in ketosis? ▼

Common signs include reduced hunger, increased energy, mental clarity, and fruity breath. For precision, use blood ketone meters (most accurate), urine strips (good for beginners), or breath analyzers. Blood ketones of 0.5-3.0 mmol/L indicate nutritional ketosis.
