Carnivore Diet Fat to Protein Ratio Calculator

Calculate the optimal fat to protein ratio for your carnivore diet based on your body weight, activity level, and goals.

Body Weight Enter your current body weight

Weight Unit

Daily Protein Intake (g) Your target daily protein consumption in grams

Activity Level

Fat to Protein Ratio: 1.5:1 Adjust the ratio of fat to protein in your diet (0.5:1 to 3:1)

Diet Goal

Ketosis Mode (higher fat for ketone production)

Quick Examples:

How to Use This Calculator

Enter your current body weight and select the unit of measurement
Input your target daily protein intake in grams
Select your activity level from the dropdown menu
Adjust the fat to protein ratio slider to your preference
Choose your diet goal (weight loss, maintenance, or muscle gain)
Click Calculate to see your recommended fat intake and macronutrient breakdown

Formula Used

Fat Intake (g) = Protein Intake (g) × Fat:Protein Ratio

Where:

Fat Intake = Recommended daily fat consumption in grams
Protein Intake = Target daily protein consumption in grams
Fat:Protein Ratio = Desired ratio of fat grams to protein grams

Example Calculation

Real-World Scenario:

A 75kg male who is moderately active and wants to maintain his weight on a carnivore diet.

Given:

Body Weight = 75 kg
Protein Intake = 120 g
Fat:Protein Ratio = 1.5:1
Activity Level = Moderate
Goal = Maintenance

Calculation:

Fat Intake = 120 g × 1.5 = 180 g

Protein Calories = 120 g × 4 kcal/g = 480 kcal

Fat Calories = 180 g × 9 kcal/g = 1620 kcal

Total Calories = 480 kcal + 1620 kcal = 2100 kcal

Result: The person should consume 180g of fat per day, resulting in a total of 2100 calories with approximately 77% of calories from fat and 23% from protein.

Why This Calculation Matters

Practical Applications

Optimizing energy levels on a carnivore diet
Achieving and maintaining ketosis
Balancing macronutrients for body composition goals

Key Benefits

Ensures adequate fat intake for hormone production
Helps prevent protein-sparing effect for energy
Supports metabolic flexibility and fat adaptation

Common Mistakes & Tips

Many carnivore diet beginners consume too much protein without adequate fat, which can lead to gluconeogenesis (excess protein converting to glucose), potentially kicking you out of ketosis. Aim for at least a 1:1 fat to protein ratio, or higher if your goal is ketosis.

Your activity level significantly impacts your energy needs. Very active individuals may need more protein for muscle repair and more fat for energy, while sedentary individuals may need to reduce overall intake. Adjust your ratios based on your daily energy expenditure.

Frequently Asked Questions

The ideal ratio varies based on individual goals. For general health and maintenance, a ratio between 1:1 and 2:1 (fat:protein) is common. For weight loss or deeper ketosis, a higher ratio of 2:1 to 3:1 may be beneficial. For muscle gain, a lower ratio around 0.8:1 to 1:1 might be preferred.

Protein needs vary based on body weight, activity level, and goals. A general guideline is 1.5-2.5g of protein per kg of body weight for active individuals, or 0.8-1.2g per kg for sedentary individuals. Those focusing on muscle building may need higher amounts, while those in ketosis for therapeutic reasons might aim for the lower end of the range.

Yes, but it requires attention. Animal products contain electrolytes, but you may need to supplement or consume specific parts of animals. Bone broth, organ meats, and animal blood are excellent sources. Many carnivores add salt (sodium) to their meals and may supplement with potassium and magnesium, especially during the adaptation phase.
