Mathematical Formulas & Calculation Methods

Standard Ketogenic Diet (SKD) Macro Distribution

Calculates daily grams based on 5% calories from net carbs, 25% from protein, and 70% from healthy fats.

Net Carbs (g) = (Total Calories × 0.05) / 4 | Protein (g) = (Total Calories × 0.25) / 4 | Fat (g) = (Total Calories × 0.70) / 9

Net Carbohydrate Definition

Net carbs represent digestible carbohydrates that impact blood glucose levels.

Net Carbs = Total Carbohydrates - Dietary Fiber - Sugar Alcohols (if applicable)

Worked Step-by-Step Examples

Example 1: 1,800 Calorie Keto Fat Loss Target

"Calculate daily macro targets in grams for a daily intake of 1,800 calories."

Steps:

Net Carbs (5%): 1,800 × 0.05 = 90 kcal → 90 / 4 = 22.5 grams net carbs.
Protein (25%): 1,800 × 0.25 = 450 kcal → 450 / 4 = 112.5 grams protein.
Fat (70%): 1,800 × 0.70 = 1,260 kcal → 1,260 / 9 = 140 grams fat.

Result: 22.5g Net Carbs | 112.5g Protein | 140g Fat

What is Calculateur de Keto Macro & Net Carb?

A keto calculator is a nutritional macro tool designed to calculate the exact ratio of fat, protein, and carbohydrates required to transition the human body into ketosis.

Tracking daily net carbs for ketosis is crucial because keeping digestible carbohydrates below 20 to 50 grams per day depletes liver glycogen stores, signaling the liver to produce ketone bodies from fatty acids for energy.

Establishing an optimal keto macros for fat loss balance ensures adequate protein to protect lean muscle tissue while utilizing dietary and stored body fat as primary energy sources.

Frequently Asked Questions

What is the difference between total carbs and net carbs?

Total carbs include dietary fiber and sugar alcohols. Net carbs subtract fiber because indigestible fiber does not spike blood sugar or disrupt ketosis.

How many net carbs should I eat daily on keto?

Most individuals enter ketosis by staying below 20 to 30 grams of net carbs per day.
