Carbohydrates

25 g
Protein:90 g
Fat:140 g
💡

Expert Tip

Keep net carbs below 20-30 grams to reliably enter ketosis. Protein acts as a building block, while fat provides the remaining calories.

Calculation Methodology & Details

📐

Formula

Carbs = Set Net Limit Protein = (Calories × Prot%) / 4 Fat = (Calories − Carbs×4 − Protein×4) / 9

Ketogenic diets prioritize high fat (70-75%), moderate protein (20-25%), and minimal carbs (5%).

FAQ

Which formula is used for calculating BMR & TDEE?
Most tools utilize the Mifflin-St Jeor equation, widely considered by clinicians as the most accurate standard for estimating resting metabolic rate.
How should I adjust macronutrient targets for my goals?
Protein is typically prioritized based on lean mass (1.6-2.2g per kg), while dietary fats and carbohydrates fill the remaining daily caloric allowance depending on diet preference (e.g. keto vs. balanced).
Can I rely on these numbers for therapeutic dietary management?
These tools provide baseline estimates for general wellness and fitness tracking. Patients with metabolic disorders, diabetes, or renal disease should consult a registered dietitian or physician.
