What is the Ketogenic Diet?

The ketogenic (keto) diet is a high-fat, moderate-protein, low-carbohydrate diet that forces your body to burn fat for fuel instead of carbohydrates. By drastically reducing carb intake and increasing fat consumption, your body enters a metabolic state called ketosis.

Keto macros typically follow this ratio: 70-80% fat, 15-25% protein, and 5-10% carbohydrates (usually 20-50g net carbs per day). Our calculator helps you determine the exact macro targets for your individual needs.

How to Calculate Your Keto Macros

  1. Enter your age, gender, height, and weight
  2. Select your activity level
  3. Choose your goal (maintain, lose, or gain weight)
  4. Set your daily net carb target (typically 20-50g for keto)
  5. Click "Calculate Keto Macros" to see your personalized targets

Understanding Your Keto Macro Results

Your keto macro breakdown follows the ketogenic diet principles:

  • High Fat (70-80%): Primary energy source on keto, supports ketosis
  • Moderate Protein (15-25%): Preserves muscle mass, typically 1g per lb of body weight
  • Low Carbs (5-10%): Keeps you in ketosis, usually 20-50g net carbs per day

Frequently Asked Questions

Q: What are net carbs?

A: Net carbs = Total carbs - Fiber - Sugar alcohols. On keto, you count net carbs, not total carbs, as fiber doesn't significantly impact blood sugar.

Q: How many net carbs should I eat on keto?

A: Most people stay in ketosis with 20-50g of net carbs per day. Some individuals can tolerate up to 100g, but this varies based on activity level and metabolism.

Q: Can I eat too much protein on keto?

A: Excessive protein (over 2g per lb of body weight) can potentially kick you out of ketosis as your body may convert excess protein to glucose. Stick to moderate protein levels.
