Your Personalized Macro Targets
Here’s what your daily nutrition should look like on an animal-based diet
🥩 Daily Meat Recommendations
Meat Intake: 0 lbs of high-quality, grass-fed meat per day
Focus on fatty cuts like ribeye, ground beef (80/20), or lamb to hit your fat targets naturally. Ruminant animals such as beef, bison, lamb, and goat are your best choices.
🫀 Organ Meat Targets
Liver: 0.5 oz daily (approximately 2-3 oz per week)
Other Organs: 2-4 oz per day of heart, kidney, bone marrow, spleen, or other organs
Can’t stomach fresh organs? Desiccated organ supplements provide the same nutritional benefits in capsule form.
🍯 Carbohydrate Sources
Based on your activity level, consume carbohydrates primarily from fruit and honey.
Best choices include: ripe bananas, berries, melons, tropical fruits, raw honey, and if tolerated, raw dairy products. Avoid plant defense chemicals found in leaves, stems, roots, and seeds.

Getting Started with Your Macros
So you have your numbers—now what? Let me walk you through exactly how to put these macros into practice. Think of this as your roadmap to making the animal-based diet work for your life.
Building Your Plate
Start with the protein. For every 100 lbs of your goal body weight, you’ll want roughly 1 lb of meat. If your target is 150g of protein and you’re eating ribeye (about 20g protein per 100g), you’ll need about 750g or 1.65 lbs of meat total throughout the day.
Your fat intake naturally follows when you choose fattier cuts. An 80/20 ground beef patty or a marbled ribeye steak delivers both protein and fat in ideal ratios. This is why animal-based eating feels so satisfying—you’re not separating nutrients artificially.
Timing Your Meals
There’s no magic number of meals you need to eat. Some people thrive on two larger meals, others prefer three moderate ones. The key is hitting your macro targets by the end of the day. Many find that front-loading protein at breakfast sets them up for stable energy and better appetite control.
Adjusting for Your Activity
Notice how carbs scale with your training volume? That’s intentional. On rest days, you might stick to the lower end with some berries and a bit of honey. After a hard training session, you can bump up to the higher range with extra fruit, honey in your post-workout meal, or even some white rice if you tolerate it well.
Why These Numbers Matter
You might wonder why animal-based macro targets look different from what you see in mainstream diet advice. The answer lies in how these foods interact with your biology.
Protein: Your Body’s Building Blocks
Animal protein contains all essential amino acids in the ratios your body actually uses. When you eat 150g of protein from beef, your body can utilize nearly all of it for muscle repair, hormone production, enzyme creation, and immune function. Compare that to plant proteins, which lack certain amino acids and contain antinutrients that block absorption.
The 1-1.2g per pound of goal body weight recommendation comes from research on optimal muscle protein synthesis and metabolic health. Going below this can compromise lean mass, especially if you’re in a caloric deficit for fat loss.
Fat: More Than Just Energy
Animal fats, particularly those rich in stearic acid like tallow and suet, do something remarkable—they improve your mitochondrial function. Your mitochondria are the energy factories in your cells, and the type of fat you eat directly impacts how efficiently they run.
Saturated and monounsaturated fats from animals are stable, meaning they don’t oxidize easily in your body. This contrasts sharply with the polyunsaturated fats in seed oils and grain-fed animals, which can damage cellular membranes and promote inflammation.
Carbs: Fuel for Performance and Hormones
Here’s where animal-based differs from carnivore: we include strategic carbohydrates from fruit and honey. Why? Because carbs support thyroid function, sex hormone production, sleep quality, and athletic performance. They’re particularly crucial for women’s hormonal health and for anyone training intensely.
The key is choosing sources without plant defense chemicals. Fruit is essentially the reproductive organ of plants—they want you to eat it. Leaves, stems, seeds, and roots? Not so much. Those are protected by compounds that can irritate your gut, trigger immune responses, or interfere with nutrient absorption.
| Macronutrient | Role in Your Body | Best Animal-Based Sources |
|---|---|---|
| Protein | Muscle building, tissue repair, enzyme production, immune function | Beef, lamb, bison, organ meats, eggs |
| Fat | Energy, hormone production, brain function, nutrient absorption, cell membrane structure | Fatty beef cuts, lamb, suet, tallow, butter, egg yolks |
| Carbohydrates | Quick energy, glycogen replenishment, thyroid support, hormone balance | Fruit, raw honey, raw milk, white rice |
Common Questions Answered
Fine-Tuning Your Approach
Once you’ve spent a few weeks hitting your macro targets consistently, you’ll start noticing patterns. This is where the real personalization happens.
Signs You Need More Carbs
Your body will tell you if carbs are too low. Watch for poor sleep quality, especially trouble staying asleep. Women might notice irregular cycles or loss of menstrual periods. Training performance suffers—weights feel heavier, cardio feels harder, recovery takes longer. You might feel cold more often or notice your libido dropping. These are all signals to increase fruit and honey intake.
Signs You Need More Fat
Constant hunger between meals despite adequate protein suggests insufficient fat. Your skin might become dry, or you might feel tired despite sleeping well. Fat provides lasting energy and satiety. If you’re grazing on snacks constantly or thinking about your next meal right after eating, bump up your fat intake.
Signs You Need More Protein
Losing strength in the gym or noticing muscle loss signals inadequate protein. Your hair might thin, nails become brittle, or wounds heal slowly. Protein needs increase with stress, illness, or intense training. If you’re hungry soon after meals that contained plenty of carbs and fat, you probably need more protein.
Animal-Based vs. Other Approaches
Let’s clear up some confusion about how animal-based differs from other popular diets you might have heard about.
| Diet Approach | Carb Intake | Food Sources | Key Difference |
|---|---|---|---|
| Animal-Based | 100-250g depending on activity | Meat, organs, fruit, honey, raw dairy | Includes strategic carbs from low-toxicity sources |
| Carnivore | 0-20g | Only animal products | Zero or minimal plant foods |
| Ketogenic | 20-50g | High fat, moderate protein, various sources | Focuses on ketone production, allows plant fats |
| Paleo | 50-150g | Meat, fish, vegetables, nuts, seeds | Includes many plant foods with defense chemicals |
Why Not Just Go Full Carnivore?
Some people thrive on carnivore, especially short-term for addressing specific health issues. However, many—particularly women, athletes, and younger individuals—do better with some carbohydrates. Carbs support thyroid function, sex hormones, sleep architecture, and training adaptations. The animal-based approach provides these benefits while avoiding the problematic compounds in vegetables, grains, legumes, and nuts.
What About Keto?
Ketogenic diets can be therapeutic for certain conditions like epilepsy or neurological issues. But staying in ketosis long-term isn’t necessary for most people and may actually compromise performance and hormone health. Animal-based gives you metabolic flexibility—your body can efficiently burn both fat and carbohydrates for fuel, which is how humans evolved to function.
Mistakes to Avoid
After helping hundreds of people adopt this way of eating, certain pitfalls come up repeatedly. Save yourself the trial and error by learning from others’ experiences.
Undershooting Protein
This is the number one issue. People think they’re eating enough meat, but when they actually weigh it, they’re falling short. One pound of raw meat is quite a bit of food—picture a large ribeye or more than four quarter-pound burger patties. Track for at least a week to calibrate your portion sizes.
Choosing Lean Cuts Exclusively
Chicken breast and sirloin have their place, but relying on them exclusively makes hitting your fat target difficult without adding excessive protein. You’ll end up either hungry or having to add fat separately. Instead, build meals around fattier options like ground beef, lamb, or ribeye. Your wallet might actually prefer this—fattier cuts are often cheaper per pound than premium lean cuts.
Fearing Fruit and Honey
Some people come to animal-based from strict carnivore or keto and carry lingering carb phobia. If you’re active and metabolically healthy, carbs from fruit and honey support your performance and hormones. They’re not the enemy—processed sugars and high-fructose corn syrup are. There’s a massive difference between an apple and a candy bar, even if they contain similar amounts of sugar.
Neglecting Organ Meats
Muscle meat alone doesn’t provide optimal nutrition. You need the vitamins and minerals concentrated in organs. Even small amounts make a significant impact. Start with just a small piece of liver once or twice a week. Many people find mixing ground liver into ground beef makes it undetectable. Or take the easy route with desiccated organ supplements.
Not Adjusting for Individual Needs
These macro recommendations are starting points, not rigid rules. A 22-year-old CrossFit athlete and a 50-year-old recovering from metabolic syndrome have very different needs. Pay attention to how you feel, perform, and progress. Adjust based on real-world feedback, not just the calculator.
Ignoring Food Quality
A 1,500-calorie diet of grass-fed beef, organs, and fruit affects your body differently than 1,500 calories of feedlot meat, processed foods, and sugar. Quality matters enormously. Grass-fed ruminants have better fatty acid profiles, higher micronutrient content, and lack the antibiotics and hormones common in conventional meat. It costs more upfront but pays dividends in how you feel.
Tracking and Monitoring Progress
Numbers on the calculator are just the beginning. Real success comes from tracking the right metrics and adjusting based on what you observe.
What to Track
Beyond the scale, pay attention to how your clothes fit, your strength in the gym, energy levels throughout the day, sleep quality, and mental clarity. Take progress photos every 2-4 weeks—they often reveal changes the scale misses. Track your workouts to monitor performance trends. Many people find keeping a daily journal helpful for connecting diet changes to how they feel.
When to Adjust Your Macros
Give any new macro split at least 2-3 weeks before making changes. Your body needs time to adapt. If fat loss stalls for more than two weeks despite consistency, you might need to reduce overall intake slightly or increase activity. If energy or performance drops, you might need more carbs or fat. If you’re losing weight but also losing strength, bump up protein or reduce your caloric deficit.
Using Apps and Trackers
Apps like Cronometer or MyFitnessPal can help you log food and see where you’re actually landing versus targets. This is especially useful in the first few weeks while you learn portion sizes. Once you have a feel for what 150g of protein looks like across your meals, you might not need to track as rigorously. Some people prefer to track indefinitely for accountability; others find it tedious after the initial learning period.
