Carnivore Tdee Calculator

Carnivore TDEE Calculator

kg lbs
cm inches
Sedentary (little or no exercise) Lightly Active (light exercise/sports 1-3 days/week) Moderately Active (moderate exercise/sports 3-5 days/week) Very Active (hard exercise/sports 6-7 days a week) Extra Active (very hard exercise/physical job/training twice a day)

Your Estimated Daily Calorie Needs:

Basal Metabolic Rate (BMR): calories/day

Total Daily Energy Expenditure (TDEE): calories/day

Maintenance Calories: calories/day

Cutting Calories (approx. -500 kcal): calories/day

Bulking Calories (approx. +300 kcal): calories/day

These are estimates. Individual needs may vary based on metabolism, body composition, and specific diet adherence.

Understanding Your Energy Needs on a Carnivore Diet

Embarking on a carnivore diet involves a significant shift in your eating habits, focusing exclusively on animal products. While the principles of energy balance remain the same – calories in vs. calories out – understanding your Total Daily Energy Expenditure (TDEE) is crucial for achieving your health and fitness goals, whether that's weight loss, maintenance, or muscle gain.

What is TDEE?

TDEE stands for Total Daily Energy Expenditure. It's an estimate of how many calories you burn in a 24-hour period, taking into account your Basal Metabolic Rate (BMR) and your activity level. Your BMR is the number of calories your body needs to perform basic, life-sustaining functions at rest (like breathing, circulation, and cell production). Your TDEE then adds the calories burned through physical activity, digestion, and other daily movements.

Why is TDEE Important for Carnivores?

  • Weight Management: To lose weight, you need to consume fewer calories than your TDEE. To gain weight (muscle), you need to consume more. For maintenance, you aim to match your TDEE.
  • Satiety and Nutrient Density: The carnivore diet is inherently high in protein and fat, which are highly satiating. This can naturally lead to eating fewer calories without feeling deprived. However, it's still possible to overeat or undereat, making TDEE a valuable guide.
  • Thermic Effect of Food (TEF): Protein has a higher TEF than carbohydrates or fats, meaning your body expends more energy to digest and metabolize protein. While standard TDEE calculators don't explicitly factor in diet type, the high protein intake on a carnivore diet might slightly increase your actual energy expenditure compared to a mixed diet with the same calculated TDEE.
  • Energy Levels: Understanding your TDEE helps ensure you're consuming enough energy to support your activity levels and overall well-being, preventing fatigue or nutrient deficiencies.

How to Use This Calculator

Our Carnivore TDEE Calculator uses the widely accepted Mifflin-St Jeor equation to estimate your BMR, then applies an activity factor to determine your TDEE. Here's a breakdown of the inputs:

  • Age: Your metabolic rate naturally slows down as you age.
  • Gender: Men generally have a higher BMR than women due to differences in body composition (more muscle mass).
  • Weight & Height: These are crucial for calculating your body's surface area and overall metabolic size.
  • Activity Level: This factor accounts for the calories you burn through exercise and daily movement. Be honest with yourself to get the most accurate estimate.

Interpreting Your Results

  • BMR: The minimum calories your body needs to function at rest.
  • TDEE / Maintenance Calories: The estimated calories you need to consume daily to maintain your current weight.
  • Cutting Calories: If your goal is fat loss, aiming for a deficit of around 500 calories below your TDEE is a common starting point for sustainable weight loss (approximately 1 pound per week).
  • Bulking Calories: If your goal is muscle gain, a surplus of 300-500 calories above your TDEE can support muscle growth.

Important Considerations for Carnivores

While this calculator provides a solid estimate, remember that individual results can vary. Factors like your specific body composition (muscle vs. fat), metabolic adaptations to the carnivore diet, and even gut health can influence your actual energy needs. Use these numbers as a starting point, monitor your progress, and adjust your intake as needed. Listen to your body, especially on a carnivore diet where satiety signals can be very strong.
