The animal-based diet is an eating approach built around meat, organ meats, fruit, honey, and raw dairy as its core foods. Popularized by physician Paul Saladino, it differs from a strict carnivore diet by including select carbohydrate sources like berries, tropical fruits, and honey while eliminating most vegetables, grains, legumes, and seed oils. The central idea is that animal foods provide the highest concentration of bioavailable nutrients, and the plant foods that are included are chosen specifically because they’re low in compounds that may interfere with nutrient absorption.
What You Eat on the Animal-Based Diet
The food list is narrower than most diets but more flexible than pure carnivore eating. The foundation is ruminant meat (beef, bison, lamb), with a strong emphasis on organ meats. Liver is considered especially important, with a recommended intake of about half an ounce daily or two to three ounces per week. Beyond liver, the diet encourages variety: heart, bone marrow, kidney, and other organs all make the list.
Carbohydrates come from fruit and honey rather than grains or starchy vegetables. A typical day might include around 10 tablespoons of raw honey, 550 grams of blueberries, 250 grams of watermelon or papaya, or 200 grams of squash with skin and seeds removed. Raw dairy rounds out the diet, with roughly a liter of raw milk spread across four meals plus butter. Pasteurized dairy is generally avoided on the premise that raw dairy retains more of its original nutrient profile.
What’s notably absent: leafy greens, cruciferous vegetables, grains, beans, nuts, seeds, and processed foods of any kind.
The Reasoning Behind Excluding Vegetables
The diet’s most counterintuitive feature is its rejection of foods most people consider healthy, like spinach, kale, and broccoli. The rationale centers on naturally occurring compounds in plants called antinutrients. These include oxalates, phytates, and lectins, which are bioactive substances that can interfere with how your body absorbs minerals and other nutrients.
Oxalates, for example, bind to calcium and prevent your body from absorbing it. They’re found in raw spinach, kale, broccoli, and soybeans. Phytates, concentrated in grains and legumes, can reduce absorption of iron and zinc. In large amounts, these compounds may contribute to bloating, nausea, or nutritional deficiencies. That said, research published in The Open Biotechnology Journal notes that antinutrients in vegetables and whole grains are primarily a concern when someone’s diet is composed exclusively of uncooked plant foods. Cooking, soaking, and fermenting significantly reduce their levels.
Animal-based diet proponents argue that since animal foods deliver the same vitamins and minerals without these absorption barriers, there’s no reason to eat plants that come packaged with defense chemicals. Critics counter that the beneficial compounds in plants (fiber, polyphenols, various antioxidants) outweigh the downsides of antinutrients for most people.
Why Fruit and Honey Instead of Starches
Unlike a ketogenic or zero-carb carnivore diet, the animal-based approach embraces carbohydrates, just from specific sources. Fruit and honey are preferred over complex starches like potatoes or rice. One line of reasoning involves how your body processes these sugars. Honey contains compounds that naturally slow the breakdown of complex starches into simple sugars by inhibiting certain digestive enzymes, which may help moderate blood sugar response. Research in the journal Nutrients has explored honey’s potential protective effects against metabolic syndrome through this mechanism.
The practical result is a diet that’s not low-carb by default. Recommended carbohydrate intake ranges from 0.7 to 1.2 grams per pound of your goal body weight. For someone targeting 150 pounds, that’s 105 to 180 grams of carbs daily, all sourced from fruit and honey. People working to improve metabolic health may start lower, around 90 to 120 grams.
Macronutrient Targets
The diet uses goal body weight as the anchor for calculating how much to eat. The general framework looks like this:
- Protein: 1 to 1.2 grams per pound of goal body weight
- Fat: 0.8 to 1 gram per pound of goal body weight
- Carbohydrates: 0.7 to 1.2 grams per pound of goal body weight
For a person with a goal weight of 150 pounds, that translates to roughly 150 to 180 grams of protein, 120 to 150 grams of fat, and 105 to 180 grams of carbohydrates per day. This is a high-protein, moderate-fat, moderate-carb profile, which sets it apart from both keto (very low carb, very high fat) and standard dietary guidelines (lower protein, higher carb).
Nutrient Density Claims
A central selling point of the diet is that animal foods, particularly organ meats, pack more vitamins and minerals per calorie than most plant foods. Beef liver is the go-to example: a 100-gram serving delivers over 500% of the recommended daily intake of vitamin A and roughly 3,000% of vitamin B12. Kale, often cited as a nutritional powerhouse, leads in vitamin K (about 600% of the daily value per 100 grams) and vitamin C but falls short on protein and several minerals by comparison.
The diet also highlights nutrients that are difficult to get from plant sources alone. Vitamin B12, iron in its most absorbable form, iodine, selenium, and zinc are all abundant in animal foods. Research published in Cureus found that vegetarian and vegan diets carry a risk of deficiency in B12, selenium, vitamin A, iron, and iodine, all of which play essential roles in thyroid function. Selenium protects the thyroid gland from oxidative damage and helps regulate immune function, while iodine is required for thyroid hormone production. Deficiencies in these nutrients can worsen both overactive and underactive thyroid conditions.
Meat Quality and Sourcing
Proponents place significant emphasis on where your meat comes from. Grass-finished beef is preferred over grain-finished for several reasons. It tends to be lower in total calories because it carries less fat, and it contains higher levels of omega-3 fatty acids compared to grain-fed beef. The omega-3 to omega-6 ratio matters because omega-6 fatty acids, consumed in excess, can promote inflammation. Grass-finished meat offers a more favorable balance between the two.
For those on a budget, the general advice is to prioritize grass-finished for fattier cuts (where the fat composition matters most) and worry less about sourcing for leaner cuts. Organ meats, which are central to the diet, are typically inexpensive regardless of sourcing.
What the Blood Work Shows
One of the biggest concerns with any high-fat, animal-heavy diet is its effect on cholesterol. An exploratory study published in Cureus tracked blood parameters in people following a self-directed carnivore diet in Germany. Total cholesterol rose from a median of 224 mg/dL before the diet to 305 mg/dL on the diet. LDL cholesterol, often called “bad” cholesterol, jumped from 157 mg/dL to 256 mg/dL. Both changes were statistically significant.
The picture was more mixed for other markers. HDL cholesterol (the “good” kind) increased modestly from 64 to 78 mg/dL. Triglycerides stayed roughly stable, dropping slightly from 110 to 104 mg/dL. Two participants who started with pre-diabetic blood sugar markers saw improvement, and six participants with initially high triglycerides experienced reductions. The long-term cardiovascular implications of substantially elevated LDL on this type of diet remain a point of active debate, and the study was small with only 14 to 16 participants providing blood data.
Gut Health Considerations
The animal-based diet is inherently low in fiber, which raises questions about gut health. A 2024 study published in NPJ Biofilms and Microbiomes compared high-fat and high-fiber diets and found that both significantly altered the composition of gut bacteria. In the high-fat group, beneficial bacteria like Bacteroides dropped from 7.8% to 2.9% of the gut population, while less common species expanded rapidly. One bacterium, Lactococcus, went from undetectable to over 20% of the gut population.
These shifts suggest that a high-fat, low-fiber eating pattern meaningfully reshapes your gut microbiome. Whether those changes are harmful over years or decades isn’t settled. Proponents of the animal-based diet argue that the fruit and honey components provide enough prebiotic material to support a healthy gut, but the research on this specific combination is limited.
How It Differs From Carnivore and Keto
The animal-based diet sits in a unique spot between several popular approaches. A strict carnivore diet allows only animal products: meat, eggs, and sometimes dairy, with zero plant foods. Keto restricts carbohydrates to roughly 20 to 50 grams per day to keep the body in a fat-burning state called ketosis. The animal-based diet is neither. It permits 100 to 180 grams of carbohydrates daily from fruit and honey, which is far too much for ketosis, and it includes plant foods that a strict carnivore would reject.
Compared to a standard omnivore diet, the biggest differences are the complete elimination of grains, legumes, nuts, seeds, vegetable oils, and most vegetables. It’s essentially an elimination diet that keeps the foods it considers most nutrient-dense and least likely to cause digestive or inflammatory issues, then adds back only the plant foods it views as safe.
