Calculate Your Animal Based Macros
Enter your current body weight.
Enter your height.
Enter your age in years.
Select your biological gender.
Choose the option that best describes your daily activity.
Select your primary fitness goal.
Desired percentage of calories from protein (e.g., 30-40% for animal-based).
Desired percentage of calories from fat (e.g., 50-70% for animal-based).
Your Animal Based Macro Targets
How these numbers are calculated: Your Basal Metabolic Rate (BMR) is estimated using the Mifflin-St Jeor equation. This is then multiplied by your activity level to get your Total Daily Energy Expenditure (TDEE). Finally, your calorie goal is adjusted based on your weight goal, and macros are distributed according to your chosen percentages (Protein: 4 kcal/g, Carbs: 4 kcal/g, Fat: 9 kcal/g).
What is an Animal Based Macro Calculator?
An Animal Based Macro Calculator is a specialized tool designed to help individuals following an animal-based diet determine their optimal daily intake of macronutrients: protein, fat, and carbohydrates. Unlike generic macro calculators, this tool is tailored to the unique nutritional philosophy of an animal-based approach, which typically emphasizes high protein and fat from animal sources while keeping carbohydrates very low, primarily from select fruits or honey, or entirely eliminating them in stricter carnivore variations.
Who Should Use an Animal Based Macro Calculator?
- Individuals on an Animal-Based Diet: Anyone committed to an animal-based eating pattern, whether for health, performance, or personal preference.
- Weight Management: Those looking to lose weight, gain muscle, or maintain their current weight effectively by precisely tracking their intake.
- Athletes and Bodybuilders: To optimize recovery, muscle growth, and energy levels by ensuring adequate protein and fat intake.
- Health Seekers: People aiming to improve metabolic health, reduce inflammation, or address specific health concerns often associated with animal-based nutrition.
- Beginners to Animal-Based Eating: To establish a solid nutritional foundation and avoid common pitfalls of under- or over-eating specific macros.
Common Misconceptions about Animal Based Macros
- “Animal-based means zero carbs”: While many animal-based diets are very low-carb, some variations include small amounts of carbohydrates from specific plant foods like fruits or honey. Our Animal Based Macro Calculator allows for this flexibility.
- “All animal-based diets are the same”: There’s a spectrum, from strict carnivore (meat, salt, water) to broader animal-based approaches that include dairy, eggs, and limited plant foods. Macro ratios will vary.
- “You don’t need to track macros on an animal-based diet”: While some find success intuitively, precise tracking with an Animal Based Macro Calculator can be crucial for specific goals like rapid fat loss, muscle gain, or addressing stalls.
- “High fat is always bad”: On an animal-based diet, healthy fats from animal sources are a primary energy source and crucial for hormone production and nutrient absorption. The calculator helps you find the right balance.
Animal Based Macro Calculator Formula and Mathematical Explanation
The Animal Based Macro Calculator uses a multi-step process to determine your personalized macro targets. It starts by estimating your basal metabolic rate, then adjusts for activity, and finally distributes calories into protein, fat, and carbohydrates based on your preferences.
Step-by-Step Derivation:
- Basal Metabolic Rate (BMR) Calculation: This is the number of calories your body burns at rest to maintain basic bodily functions. We use the Mifflin-St Jeor Equation, which is widely considered one of the most accurate:
- 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
- Total Daily Energy Expenditure (TDEE) Calculation: Your TDEE is your BMR multiplied by an activity factor, which accounts for the calories you burn through daily activities and exercise.
- TDEE = BMR × Activity Multiplier
- Calorie Goal Adjustment: Based on your goal (maintain, lose, or gain weight), your TDEE is adjusted:
- Maintain Weight: Calorie Goal = TDEE
- Lose Weight: Calorie Goal = TDEE – 500 kcal (a common deficit for ~1 lb/week fat loss)
- Gain Weight: Calorie Goal = TDEE + 500 kcal (a common surplus for ~1 lb/week muscle gain)
- Macronutrient Distribution: The final step is to distribute your total calorie goal into protein, fat, and carbohydrates based on the percentages you input.
- Protein Grams: (Calorie Goal × Protein %) / 4 kcal/g
- Fat Grams: (Calorie Goal × Fat %) / 9 kcal/g
- Carbohydrate Grams: (Calorie Goal × Carbohydrate %) / 4 kcal/g
Note: The carbohydrate percentage is derived as 100% – Protein % – Fat %. For an animal-based diet, this percentage is typically very low or zero.
Variables Table:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Weight | Your body mass | kg / lbs | 40 – 150 kg (88 – 330 lbs) |
| Height | Your vertical measurement | cm / inches | 140 – 200 cm (55 – 79 inches) |
| Age | Your age in years | Years | 18 – 80 |
| Gender | Biological sex (influences BMR) | N/A | Male / Female |
| Activity Level | How active you are daily | Multiplier | 1.2 (sedentary) – 1.9 (extremely active) |
| Goal | Your fitness objective | N/A | Maintain, Lose, Gain Weight |
| Protein % | Percentage of calories from protein | % | 25% – 45% (for animal-based) |
| Fat % | Percentage of calories from fat | % | 50% – 70% (for animal-based) |
Practical Examples (Real-World Use Cases)
Let’s look at how the Animal Based Macro Calculator works with realistic scenarios.
Example 1: Weight Loss on an Animal-Based Diet
Sarah, a 35-year-old female, weighs 75 kg (165 lbs) and is 165 cm (65 inches) tall. She works a desk job but exercises moderately 3-4 times a week (Moderately Active). Her goal is to lose weight, and she prefers a higher fat intake typical of an animal-based diet, so she sets her protein at 30% and fat at 65%.
- Inputs:
- Weight: 75 kg
- Height: 165 cm
- Age: 35 years
- Gender: Female
- Activity Level: Moderately Active (1.55)
- Goal: Lose Weight
- Protein %: 30%
- Fat %: 65%
- Calculations:
- BMR: (10 * 75) + (6.25 * 165) – (5 * 35) – 161 = 750 + 1031.25 – 175 – 161 = 1445.25 kcal
- TDEE: 1445.25 * 1.55 = 2240.14 kcal
- Calorie Goal (Lose Weight): 2240.14 – 500 = 1740.14 kcal (approx. 1740 kcal)
- Carbohydrate %: 100% – 30% – 65% = 5%
- Outputs:
- Daily Calorie Goal: ~1740 kcal
- Protein: (1740 * 0.30) / 4 = 130.5 g
- Fat: (1740 * 0.65) / 9 = 125.8 g
- Carbohydrates: (1740 * 0.05) / 4 = 21.75 g
Sarah now has clear targets for her animal-based weight loss journey, ensuring she gets adequate protein for satiety and muscle preservation, and sufficient fat for energy, while maintaining a calorie deficit.
Example 2: Muscle Gain for an Active Male
David, a 28-year-old male, weighs 85 kg (187 lbs) and is 180 cm (71 inches) tall. He lifts weights 5 days a week and has an active job (Very Active). His goal is to gain muscle, and he wants a balanced animal-based macro split with higher protein. He sets his protein at 40% and fat at 55%.
- Inputs:
- Weight: 85 kg
- Height: 180 cm
- Age: 28 years
- Gender: Male
- Activity Level: Very Active (1.725)
- Goal: Gain Weight
- Protein %: 40%
- Fat %: 55%
- Calculations:
- BMR: (10 * 85) + (6.25 * 180) – (5 * 28) + 5 = 850 + 1125 – 140 + 5 = 1840 kcal
- TDEE: 1840 * 1.725 = 3174 kcal
- Calorie Goal (Gain Weight): 3174 + 500 = 3674 kcal
- Carbohydrate %: 100% – 40% – 55% = 5%
- Outputs:
- Daily Calorie Goal: ~3674 kcal
- Protein: (3674 * 0.40) / 4 = 367.4 g
- Fat: (3674 * 0.55) / 9 = 224.5 g
- Carbohydrates: (3674 * 0.05) / 4 = 45.9 g
David now has a robust calorie and macro target to fuel his intense training and support muscle hypertrophy on his animal-based diet. The higher protein ensures muscle repair and growth, while ample fat provides sustained energy.

Use these results as a starting point. Monitor your progress (weight, body composition, energy levels) and adjust your inputs, especially activity level and macro percentages, as needed. For example, if you’re not losing weight, you might slightly reduce your fat percentage or increase your activity level. If you’re feeling low on energy, you might increase your fat intake. The Animal Based Macro Calculator provides a powerful baseline for informed dietary choices.
Key Factors That Affect Animal Based Macro Calculator Results
Several critical factors influence the output of an Animal Based Macro Calculator. Understanding these can help you fine-tune your inputs for the most accurate and effective results.
- Accuracy of Body Metrics (Weight, Height, Age, Gender): These are the foundational inputs for calculating your BMR. Inaccurate measurements will lead to an incorrect BMR, which then skews all subsequent calculations. Regularly update your weight, especially if your body composition changes.
- Activity Level Selection: This is often the most subjective input. Overestimating your activity can lead to a calorie goal that’s too high, hindering weight loss. Underestimating can lead to a goal that’s too low, causing fatigue or stalling muscle gain. Be realistic and adjust if your lifestyle changes.
- Weight Goal (Lose, Maintain, Gain): The calculator applies a standard calorie adjustment (e.g., +/- 500 kcal) for weight loss or gain. While effective for many, individual metabolic rates vary. Some may need a larger or smaller deficit/surplus.
- Protein and Fat Percentage Preferences: These are highly customizable on an animal-based diet. Higher protein supports satiety and muscle, while higher fat provides sustained energy and is crucial for a low-carb approach. Experiment within healthy ranges to find what works best for your body and goals. Ensure the sum of protein and fat percentages does not exceed 100%.
- Metabolic Adaptation: Over time, your body can adapt to consistent calorie deficits, potentially slowing metabolism. This means your TDEE might decrease, requiring adjustments to your calorie goal from the Animal Based Macro Calculator.
- Individual Bio-variability: Everyone’s metabolism is unique. Factors like genetics, gut health, hormone levels, and stress can all influence how your body processes and utilizes macronutrients. The calculator provides a scientific estimate, but personal experimentation and observation are key.
Frequently Asked Questions (FAQ) about the Animal Based Macro Calculator
A: An animal-based diet primarily consists of foods derived from animals, such as meat, organs, eggs, and dairy. Some variations may include small amounts of low-toxin plant foods like fruits or honey, while stricter versions (like the carnivore diet) exclude all plant matter.
A: While the underlying BMR/TDEE calculations are similar, an Animal Based Macro Calculator is designed with the typical macro ratios of an animal-based diet in mind, often emphasizing higher protein and fat, and very low carbohydrates. It helps users align their targets with this specific dietary philosophy.
A: Yes. For a strict carnivore diet, you would typically set your protein and fat percentages to sum to 100% (e.g., 30% protein, 70% fat), resulting in 0% carbohydrates. This calculator allows for that flexibility.
A: You should recalculate your macros using the Animal Based Macro Calculator whenever your weight significantly changes (e.g., 5-10 lbs), your activity level changes, or your fitness goals shift. For consistent progress, checking every 4-8 weeks is a good practice.
A: The calculator will display an error if your protein and fat percentages exceed 100%. You must adjust them so their sum is 100% or less. The remaining percentage will be allocated to carbohydrates.
A: A 500 kcal adjustment is a common guideline for approximately 1 pound of weight change per week. However, individual results vary. You may need to adjust this based on your progress and how your body responds. Always consult with a healthcare professional for personalized advice.
A: Choose the activity level that you believe is the closest fit. If you’re unsure, it’s often better to start with a slightly lower estimate (e.g., “Lightly Active” instead of “Moderately Active”) and adjust after monitoring your results for a few weeks. Consistency in tracking is more important than initial perfection.
A: Tracking macros with an Animal Based Macro Calculator can be very beneficial for achieving specific goals like weight loss, muscle gain, or optimizing performance. It provides structure and ensures you’re consistently hitting your targets. For general health maintenance, some people may find intuitive eating sufficient once they understand the principles.
