What Is a Ketogenic Eating Pattern?

A ketogenic eating pattern is characterized by very low carbohydrate intake (typically 20–50g net carbs per day), moderate protein, and high fat. This macronutrient distribution is substantially different from the standard dietary guidelines ^[1].

The standard ketogenic ratio is approximately 70–75% calories from fat, 20–25% from protein, and 5–10% from carbohydrates. This calculator helps you determine the specific gram amounts based on your daily calorie needs ^[2].

Keto Presets Explained

• Standard Keto (≤20g): The most commonly referenced net carb target. Used as the baseline in most keto research studies
• Moderate (≤35g): Slightly higher carb allowance that some individuals find more sustainable for long-term adherence
• Liberal (≤50g): Approaches the upper boundary of low-carb eating. May not maintain the same macro ratios as a strict ketogenic pattern

To calculate net carbs for specific foods, use our Net Carbs Calculator.

Protein on Keto

This calculator uses 1.5 g/kg of body weight for protein, which falls within the range recommended for preserving lean mass during carbohydrate restriction ^[3]. Adequate protein supports body composition maintenance regardless of carbohydrate intake level.

For more detailed protein calculations, see our Protein Intake Calculator. For fat-specific targets, try the Fat Intake Calculator.
