What is the Ketogenic Diet?

The ketogenic (keto) diet is a high-fat, moderate-protein, very low-carbohydrate eating plan. By drastically reducing carbohydrate intake (typically to 20-50g net carbs per day), your body shifts from burning glucose to burning fat for fuel - a metabolic state called ketosis.

In ketosis, your liver converts fat into molecules called ketones, which become your body's primary energy source. This metabolic switch offers several potential benefits:

  • Enhanced fat burning: Your body becomes efficient at burning stored fat
  • Stable energy: No more blood sugar crashes or energy dips
  • Reduced hunger: Fat and ketones are more satiating than carbs
  • Mental clarity: Many report improved focus and cognitive function

Net Carbs vs Total Carbs

Understanding the difference between net carbs and total carbs is crucial for keto success:

Net Carbs Formula

Net Carbs = Total Carbs - Fiber - Sugar Alcohols

Why track net carbs?

  • Fiber passes through undigested and doesn't affect blood sugar
  • Most sugar alcohols have minimal impact on blood glucose
  • Net carbs represent the carbs that actually affect ketosis

Example: An avocado has 12g total carbs but 10g fiber, so only 2g net carbs count toward your daily limit.

Signs You're in Ketosis

How do you know when your body has entered ketosis? Look for these common signs:

🎯

Reduced Appetite

Ketones are highly satiating

âš¡

Increased Energy

Stable energy without crashes

🧠

Mental Clarity

Improved focus and concentration

💨

Keto Breath

Fruity or metallic breath (temporary)

For precise measurement, blood ketone meters are most accurate. Nutritional ketosis is typically indicated by blood ketone levels of 0.5-3.0 mmol/L.

Common Keto Mistakes to Avoid

Not Eating Enough Fat

Fat is your fuel on keto. Many people try to go low-carb AND low-fat, leaving them hungry and low-energy. Embrace healthy fats like avocado, olive oil, and fatty fish.

Too Much Protein

Excess protein can convert to glucose through gluconeogenesis, potentially affecting ketosis. Stick to moderate protein (0.8-1.0g per lb lean mass).

Ignoring Electrolytes

Keto causes water and electrolyte loss. Supplement sodium, potassium, and magnesium to avoid "keto flu" symptoms like headaches and fatigue.

Hidden Carbs

Carbs hide in sauces, dressings, and "low-carb" products. Always check nutrition labels and track everything, especially when starting out.

Frequently Asked Questions

What is the keto diet?

The ketogenic diet is a high-fat, moderate-protein, very low-carbohydrate diet. By reducing carbs to 20-50g per day, your body enters ketosis and burns fat for fuel instead of glucose, leading to weight loss and other health benefits.

What are the ideal keto macro ratios?

Standard keto macros are 70-75% fat, 20-25% protein, and 5-10% carbs. For strict keto, aim for 75-80% fat, 15-20% protein, and 5% carbs. Our calculator personalizes these based on your goals and body composition.

What is the difference between net carbs and total carbs?

Net carbs = Total carbs - Fiber - Sugar alcohols. On keto, track net carbs because fiber and most sugar alcohols don't affect blood sugar or ketosis. This allows you to eat more fibrous vegetables while staying in ketosis.

How many carbs can I eat and stay in ketosis?

Most people stay in ketosis eating 20-50g net carbs daily. For reliable ketosis, especially when starting, keep net carbs under 20g. As you become fat-adapted, you may tolerate more carbs while maintaining ketosis.

How much protein should I eat on keto?

Aim for 0.8-1.0g protein per pound of lean body mass. This preserves muscle while keeping protein moderate to avoid excess conversion to glucose. Our calculator factors in your body fat percentage for more accurate protein recommendations.

How do I know if I am in ketosis?

Common signs include reduced appetite, stable energy, mental clarity, and "keto breath." For accurate measurement, use blood ketone meters - nutritional ketosis is indicated by 0.5-3.0 mmol/L. Urine strips work but become less reliable as you adapt.
