The animal-based diet, a dietary approach centered around animal products, has gained traction as an alternative to conventional dietary guidelines. This article explores the concept of the animal-based diet, its potential benefits and drawbacks, and how it compares to other dietary approaches.
Defining the Animal-Based Diet
An animal-based diet emphasizes the consumption of animal products such as meat, organs, fruit, honey, raw dairy (if tolerated), and eggs. This approach often involves minimizing or eliminating plant-based foods, particularly those considered "toxic vegetables." Proponents suggest that this dietary shift can address gut imbalances and promote overall health.
Personal Anecdotes and Initial Experiences
Experiences with the animal-based diet vary. Some individuals report positive initial experiences, such as weight loss and improved energy levels. However, challenges such as constipation can arise, prompting the need to incorporate other foods like dates, bananas, and kefir to aid digestion. As one person recounted, "The first two weeks were a piece of cake…But then I had the worst constipation I’ve ever had in my entire life."
From Plant-Based to Animal-Based: A Dietary Shift
The animal-based diet represents a significant departure from traditional plant-based diets. One individual noted that their parents were "kind of health nuts" and primarily followed a plant-based diet, which was "pretty much the exact opposite of animal based." This highlights the contrasting nature of these dietary philosophies.
Individual Sensitivities and Universal Truths
It's crucial to recognize that individual responses to different diets can vary significantly. As one person stated, "I’m a firm believer in what works for you works for you. Everyone has different sensitivities and preferences and ailments." While some foods like chocolate, processed fast food, and high fructose corn syrup are widely considered unhealthy, opinions on the healthfulness of meat, fat, and gluten differ.

The Animal-Based Diet as an Experiment
For many, adopting an animal-based diet is an ongoing experiment. Personal observations include:
- Increased protein consumption, facilitating muscle building.
- Reduced gas and stomach discomfort due to minimal vegetable and legume intake.
- Stable energy levels after meals, preventing afternoon crashes.
- Reduced cravings and increased satiety, minimizing the desire for dessert.
- Simplified meal preparation and cost-effective grocery shopping.
- Consistent enjoyment of meals, even with repetitive choices like chicken breast and fried eggs.
Occasional Cheats and Evolving Preferences
While primarily adhering to an animal-based diet, occasional deviations may occur. However, over time, preferences may shift, with a reduced enjoyment of "normal" meals. For example, one might opt for a burger without the bun or skip side dishes like salads or mashed potatoes.
Scientific Perspectives on Animal-Based vs. Plant-Based Diets
A study published in the British Journal of Nutrition (2020) assessed the quality of plant-based versus animal-based foods in relation to mortality. The study, using data from a nationally representative sample of 36,825 adults, developed a Comprehensive Diet Quality Index (cDQI) to evaluate the quality of 17 foods. The results indicated that a higher quality plant-based diet was associated with a lower risk of all-cause mortality, while no independent association was found for the quality of animal-based foods and mortality.
The Role of Fiber and Gut Health
Plant-based diets are often recommended for preventing chronic diseases such as obesity, diabetes, cardiovascular disease, and cancer. These diets are typically rich in fiber, which plays a crucial role in gut health. However, the study mentioned above suggests that the quality of plant-based foods, rather than simply the presence or absence of animal foods, is a key factor in determining health outcomes.
Study Methodology
The study utilized data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2014. Dietary intake was assessed through 24-hour recalls, and mortality data was obtained from the National Death Index. The cDQI was developed to assess the quality of both plant-based and animal-based food components of the diet.

Key Findings
The study found that individuals in the highest quartile of cDQI had a 25% lower risk of all-cause mortality compared to those in the lowest quartile. After controlling for the quality of animal-based foods, individuals in the highest quartile of plant-based diet quality had a 34% lower risk of all-cause mortality. Higher intake of vegetables, whole fruits, nuts/seeds/legumes, vegetable oils, and coffee/tea was associated with lower all-cause mortality.
Personal Experience with a Carnivore Diet
One individual shared their experience with a full carnivore diet, eliminating all plant foods and drinks. They noted saving time and money on shopping and meal preparation. They also experienced better mental clarity, sustained energy, and improved sleep quality. Gut test results revealed a shift towards a more favorable ratio of Bacteroidetes to Firmicutes, even without consuming fermented veggies or fiber.
Body Composition Changes
Body composition analysis revealed a gain of 1kg of lean muscle and 1.5kg of fat in a short period. However, concerns about bone density led to the reintroduction of some vegetables.
Performance and Recovery
Initially, the individual felt terrible and experienced a decline in performance. However, after becoming fat-adapted, they felt lighter and faster. They also experienced improved recovery after races, with less fatigue and muscle soreness.
Lessons Learned
The individual concluded that they needed more protein and fewer veggies, fruits, and dairy to prevent bloating, cramps, and cravings. They also noted the importance of adjusting the fat-to-protein ratio to prevent weight gain.

Plant-Based Diets: Physiological and Psychological Factors
Plant-based diets are often associated with planetary and human health. Studies have shown that higher intake of dietary fiber, found in whole-grain products, vegetables, legumes, and fruits, is linked to a reduced risk of non-communicable diseases.
Macronutrient Content and Appetite Control
Macronutrient content plays a crucial role in appetite control. Energy density and protein content of meals influence subsequent metabolic activity and future meal intake. Plant-based meals have been shown to induce greater satiety compared to macronutrient-matched meat-based meals.
Psychological Mechanisms
Psychological factors, such as self-control and cognitive strategies, also influence food choices. Restrictive eating, often associated with vegetarian and vegan diets, has been linked to a higher risk of depressive symptoms. However, adequate nutrient intake, including high fiber intake, has been associated with lower depressive symptoms and anxiety.
Modulating Food Choices
Targeting food choice environments through labeling, portion size reduction, and pricing strategies can influence dietary intake. Increasing the availability of vegetarian meals in cafeterias has been shown to increase their sales without affecting overall sales.
Research on Hunger and Mood
One study aimed to determine satiety and mood before and after consuming plant-based or animal-based meals in university cafeterias. The study found that individuals choosing plant-based meals reported lower hunger on average, but post-meal mood increased less compared to those consuming animal-based meals.
Nutrient Composition and Satiety
Macronutrient analysis revealed that plant-based meals had higher carbohydrates and sugar and lower fat and protein compared to animal-based meals. Protein content was found to have a small effect on post-meal satiety.
The Importance of Protein
Protein plays a crucial role in satiety and muscle building. Consuming adequate protein can help reduce cravings, increase satiety, and facilitate muscle growth.
The Role of Fiber
Fiber is essential for gut health and can help regulate appetite. Plant-based meals often contain higher amounts of fiber compared to animal-based meals.
Personal Health Reset: An Eight-Week Update
One individual shared their eight-week health reset, which involved adopting a primarily animal-based diet and incorporating regular exercise. They reported feeling stronger, having more energy, and experiencing freedom from the cycle of hunger and restriction.
Animal-Based Success Story
Another individual shared their experience with the animal-based diet, noting that it helped them lose weight, become more active, and improve their overall health. They emphasized the importance of meal planning and making time for healthy choices.
The Carnivore Diet: A Strict Approach
The carnivore diet, a subset of the animal-based diet, involves consuming only meat and other animal products. Proponents claim that it can promote weight loss, fight inflammation, lower blood sugar, and improve mental health.
Comparison to Keto and Atkins Diets
The carnivore diet is similar to the ketogenic (keto) and Atkins diets, but it is more restrictive. While keto and Atkins diets limit carbs, the carnivore diet eliminates all carbohydrates and other food groups.
Historical Context
The concept of a carb-free diet dates back to the late 1700s, when Scottish military surgeon John Rollo used a meat-only diet to treat patients with diabetes.
Potential Benefits and Drawbacks
While the carnivore diet may lead to quick weight loss, it is highly restrictive and may result in nutrient deficiencies. It is not aligned with the Dietary Guidelines for Americans, which recommends a balanced diet with fruits, vegetables, and whole grains.
Foods Allowed and Avoided
The carnivore diet allows for the consumption of red meat, chicken, fish, seafood, and some dairy products. It excludes all fruits, vegetables, grains, legumes, nuts, and seeds.
Expert Opinions
Experts caution against the carnivore diet due to its restrictive nature and potential for nutrient deficiencies. They recommend consulting with a healthcare professional before adopting such a diet.
