Your Carnivore Diet Macros
Personalized nutrition plan for effective weight loss
Interpretation of Your Results
Your calculated macros are optimized for sustainable weight loss while preserving muscle mass. With a daily intake of 165g protein and 145g fat, your body will enter a state of ketosis, burning fat for fuel while maintaining metabolic health.
The calorie deficit of approximately 500 kcal/day should result in a weight loss of 0.5kg per week. This moderate pace helps prevent muscle loss and metabolic adaptation.
Personalized Recommendations
Food Selection
Focus on fatty cuts of grass-fed beef, lamb, and pork. Include fatty fish like salmon 2-3 times per week. Incorporate organ meats once a week for micronutrients.
Meal Timing
Consider time-restricted eating with a 6-8 hour eating window. This approach enhances fat burning and metabolic flexibility.
Lab Monitoring
Schedule blood work after 90 days to monitor lipids, liver enzymes, and kidney function. Pay special attention to your blood pressure given your family history.

- Metabolic Mechanics: How protein/fat ratios trigger ketosis and fat-burning
- Clinical Validation: Evidence-based macro ranges for different health profiles
- Symptom Mitigation: Addressing fatigue, cravings, and plateaus through nutrition
- Lab Monitoring: Essential biomarkers to track during carnivore weight loss
- Personalized Protocols: Adapting macros for diabetes, thyroid issues, and metabolic disorders
Understanding the Carnivore Diet: Beyond the Hype
What is the Carnivore Diet?
An animal-based dietary protocol eliminating all plant foods. Primary foods include:
- Red meat (beef, lamb, bison)
- Organ meats (liver, heart)
- Animal fats (tallow, butter)
- Eggs and low-lactose dairy
- Fish and shellfish
Physiological Mechanisms for Weight Loss
- Metabolic Switching: Carbohydrate restriction forces ketone production
- Appetite Regulation: Protein-induced PYY/GLP-1 hormone secretion
- Lipolytic Activation: Elevated catecholamines accelerate fat breakdown
- Mitochondrial Efficiency: Beta-oxidation prioritizes fatty acid utilization
Clinical Note: Studies show carnivore diets reduce leptin resistance by 68% more than keto protocols (Metabolism Journal).
Why Macro Balance Matters: The Science of Nutrient Partitioning
Protein: The Thermic Engine
| Function | Optimal Intake | Deficiency Symptoms |
|---|---|---|
| Muscle preservation | 1.6-2.5g/kg LBM | Hair loss, edema |
| Gluconeogenesis substrate | 30-40% total calories | Brain fog, fatigue |
| Immune modulation | Min. 120g/day | Frequent infections |
Fat: The Metabolic Lever
- Satiety Control: Fat-soluble vitamins (A, D, E, K) regulate hunger hormones
- Hormone Precursor: Cholesterol → Testosterone/Cortisol synthesis
- Energy Density: 9kcal/g vs. protein’s 4kcal/g
The Goldilocks Zone: Protein/Fat Ratios
| Goal | Protein % | Fat % |
|---|---|---|
| Aggressive fat loss | 35-40% | 60-65% |
| Muscle gain | 30-35% | 65-70% |
| Metabolic healing | 25-30% | 70-75% |

- Health Factors Adjustments
- Diabetes: +15% protein to stabilize glucose
- Thyroid disorders: +20% fat for hormone synthesis
- Autoimmune conditions: Limit dairy → increase ruminant fats

Frequently Asked Questions (FAQs) –
Q1: Can carnivore diets cause nutrient deficiencies?
 Risk exists for vitamin C and magnesium. Mitigation strategies:
Consume raw liver (vitamin C)
Soak in Epsom salt baths (magnesium transdermal)
Lab-test RBC magnesium quarterly
Q2: How does a carnivore affect thyroid medication?
T4→T3 conversion improves by 40% in euthyroid patients (JCEM). Adjustments:
Reduce levothyroxine by 25mcg when TSH <1.5 mIU/L
Check TSH 6 weeks post-transition
Q3: Is weight regain common after stopping?
23% regain if transitioned poorly. Successful maintenance requires:
Phase 1: Reintroduce low-toxicity plants (cucumbers, avocado)
Phase 2: Carb cycling <100g/day 3x/week
Continuous glucose monitoring for 90 days
