What is Carnivore TDEE?
Carnivore TDEE (Total Daily Energy Expenditure) is an estimate of the total number of calories you burn per day while following a carnivore diet. This diet primarily consists of animal products like meat, fish, eggs, and sometimes dairy, with zero or minimal carbohydrates. Your TDEE is the sum of your Basal Metabolic Rate (BMR – calories burned at rest), the thermic effect of food (TEF – calories burned digesting food), and calories burned through physical activity.
Knowing your Carnivore TDEE is crucial for managing your weight. If you eat more calories than your TDEE, you’ll likely gain weight; eat fewer, and you’ll likely lose weight. On a carnivore diet, the macronutrient composition (high protein, high fat) can also influence satiety and metabolic effects, but total energy balance still plays a key role.
Anyone following or considering a carnivore diet who wants to maintain, lose, or gain weight should use a Carnivore TDEE calculator. Common misconceptions are that calories don’t matter on carnivore or that you can eat unlimited amounts without weight gain. While satiety is high, exceeding your Carnivore TDEE consistently can still lead to weight gain.
Carnivore TDEE Formula and Mathematical Explanation
The calculation of your Carnivore TDEE starts with your Basal Metabolic Rate (BMR), which is then adjusted for your activity level.
1. Calculate BMR:
- If Body Fat % is provided, the Katch-McArdle formula is often preferred:
LBM (Lean Body Mass) = Weight (kg) * (1 – Body Fat % / 100)
BMR = 370 + (21.6 * LBM) - If Body Fat % is not provided, the Mifflin-St Jeor equation is commonly used:
For Men: BMR = (10 * weight in kg) + (6.25 * height in cm) – (5 * age in years) + 5
For Women: BMR = (10 * weight in kg) + (6.25 * height in cm) – (5 * age in years) – 161
2. Calculate TDEE:
TDEE = BMR × Activity Multiplier
The Activity Multiplier accounts for calories burned during exercise and daily activities (see table above).
3. Carnivore Macronutrients:
- Protein: A common starting point is 0.8-1.2 grams per pound of body weight (or 1.7-2.6 g/kg). You set your goal in the calculator. Protein calories = Protein (g) * 4.
- Fat: The remaining calories are allocated to fat. Fat calories = TDEE – Protein calories. Fat (g) = Fat calories / 9.
- Carbohydrates: Assumed to be near zero on a strict carnivore diet.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Age | Your age | years | 15-80 |
| Weight | Your body weight | kg or lbs | Varies |
| Height | Your body height | cm or in | Varies |
| Body Fat % | Percentage of body weight that is fat (optional) | % | 5-40 |
| Activity Multiplier | Factor representing physical activity level | None | 1.2-1.9 |
| BMR | Basal Metabolic Rate | kcal/day | 1200-2500+ |
| TDEE | Total Daily Energy Expenditure | kcal/day | 1400-4000+ |
| Protein Intake | Target protein grams per unit of body weight | g/lb or g/kg | 0.8-1.2 (g/lb) |
Practical Examples (Real-World Use Cases)
Example 1: Weight Maintenance for a Moderately Active Male
- Age: 35 years
- Gender: Male
- Weight: 180 lbs (approx. 81.6 kg)
- Height: 70 inches (approx. 177.8 cm)
- Activity Level: Moderately Active (1.55)
- Body Fat %: Not provided
- Protein Goal: 0.9 g/lb
BMR (Mifflin-St Jeor) ≈ 1795 kcal
Carnivore TDEE ≈ 1795 * 1.55 = 2782 kcal
Protein ≈ 180 * 0.9 = 162g (648 kcal)
Fat ≈ (2782 – 648) / 9 = 237g
To maintain weight, this individual would aim for around 2782 calories, with 162g protein and 237g fat daily on a carnivore diet.
Example 2: Weight Loss for a Lightly Active Female with Known Body Fat
- Age: 45 years
- Gender: Female
- Weight: 150 lbs (approx. 68 kg)
- Height: 64 inches (approx. 162.6 cm)
- Activity Level: Lightly Active (1.375)
- Body Fat %: 30%
- Protein Goal: 1.0 g/lb
LBM = 150 * (1 – 0.30) = 105 lbs (approx. 47.6 kg)
BMR (Katch-McArdle) = 370 + (21.6 * 47.6) ≈ 1398 kcal
Carnivore TDEE ≈ 1398 * 1.375 = 1922 kcal
For weight loss (e.g., a 500 kcal deficit), target intake would be ~1422 kcal.
Protein ≈ 150 * 1.0 = 150g (600 kcal)
Fat (for 1422 kcal total) ≈ (1422 – 600) / 9 = 91g
For weight loss, she might aim for 1422 calories, with 150g protein and 91g fat. Using her Carnivore TDEE for beginners guide helps.
How to Use This Carnivore TDEE Calculator
- Enter Your Details: Input your age, gender, weight (and select units), height (and select units).
- Select Activity Level: Choose the option that best describes your weekly physical activity.
- Body Fat % (Optional): If you know your body fat percentage, enter it for a potentially more accurate BMR calculation.
- Set Protein Goal: Define how many grams of protein per pound (or kg) of body weight you aim for. The unit will adjust based on your weight unit selection.
- View Results: The calculator instantly shows your estimated BMR, Carnivore TDEE (maintenance calories), and a sample macronutrient breakdown (protein and fat grams/calories) based on your protein goal and TDEE.
- Adjust for Goals: If your goal is weight loss, aim for 300-500 calories below your TDEE. For weight gain, aim for 300-500 above. Your protein goal might also change based on whether you’re aiming for carnivore muscle gain or weight loss.
The results give you a starting point. Monitor your weight, energy levels, and body composition, and adjust your intake as needed.
Key Factors That Affect Carnivore TDEE Results
- Age: Metabolic rate generally decreases with age.
- Gender: Men typically have a higher BMR than women due to more muscle mass on average.
- Weight and Height: Larger individuals burn more calories at rest and during activity.
- Body Composition: Muscle burns more calories at rest than fat. Knowing your body fat % can refine BMR estimates.
- Activity Level: The more active you are, the more calories you burn. This is the most variable factor.
- Thermic Effect of Food (TEF): Protein has a higher TEF than fat or carbs. A high-protein carnivore diet might slightly increase TEF compared to other diets with the same calories but lower protein.
- Hormonal Health: Thyroid function and other hormones can significantly impact metabolic rate.
- Adaptation to Diet: When first transitioning to a carnivore or keto diet, some people experience metabolic shifts. Learn more in our carnivore diet meal plan.
Frequently Asked Questions (FAQ)
- 1. How accurate is this Carnivore TDEE calculator?
- It provides a good estimate based on standard formulas. However, individual metabolic rates can vary. Use it as a starting point and adjust based on your results.
- 2. Why is body fat percentage optional?
- If you know your body fat %, the Katch-McArdle formula can be used, which is considered more accurate for individuals who are not of average body composition. If not, Mifflin-St Jeor is a reliable alternative.
- 3. How many calories should I eat to lose weight on carnivore?
- A common starting point for weight loss is to consume 300-500 calories less than your calculated Carnivore TDEE. Focus on high satiety from protein and fat. Explore carnivore weight loss strategies.
- 4. How much protein should I eat on a carnivore diet?
- A common range is 0.8 to 1.2 grams of protein per pound of body weight (or 1.7-2.6 g/kg), but this can vary based on activity level, goals (muscle gain vs. maintenance), and individual preference. See our guide on how much protein on carnivore.
- 5. Do I need to track calories on a carnivore diet?
- Some people thrive on carnivore by eating to satiety without tracking, especially if weight loss is easy. However, if you have specific goals or hit a plateau, tracking calories and macros using your Carnivore TDEE can be very helpful.
- 6. What if I’m not losing weight even below my Carnivore TDEE?
- Ensure your TDEE estimate and intake tracking are accurate. Consider factors like hidden carbs (if consuming dairy or processed meats), stress, sleep, and hormonal balance. Re-evaluate your activity level. Some find adjusting the fat to protein ratio carnivore helps.
- 7. Is a Carnivore TDEE different from a regular TDEE?
- The base BMR and TDEE calculation is the same. The “Carnivore” aspect refers to the macronutrient distribution (very low/zero carb, high protein/fat) and how you might use the TDEE to plan those macros.
- 8. Do I need to worry about electrolytes on a carnivore diet?
- Yes, especially when starting, as you lose water and electrolytes. Be mindful of sodium, potassium, and magnesium. More on electrolytes on carnivore.
