The Carnivore Diet: Revolutionary Health Hack Or Dangerous Trend?

Written by Dr Bikram Ratti MBBS (London) MRCGP. Private GP and Men’s Health Specialist at The Doctor’s Practice.

In the ever-evolving world of nutrition, the carnivore diet has taken centre stage as one of the most controversial and polarising dietary trends. While some hail it as the ultimate solution for weight loss, inflammation reduction, and improved metabolic health, others warn of potential long-term risks.

As a doctor who has spent over 20 years treating men with metabolic disorders, testosterone deficiencies, and inflammatory conditions, I’ve seen firsthand how diet plays a crucial role in overall health. In this article, I’ll break down the science behind the carnivore diet, its potential benefits, risks, and whether it’s a sustainable option for long-term health.

WHAT IS THE CARNIVORE DIET?

The carnivore diet is a restrictive eating plan that consists solely of animal-based foods—primarily meat, fish, eggs, and some dairy. It eliminates all plant-based foods, including vegetables, fruits, nuts, seeds, grains, and legumes.

WHY ARE PEOPLE TURNING TO THE CARNIVORE DIET?

Weight loss – High-protein, high-fat diets are known to enhance satiety and reduce cravings.
Inflammation reduction – Many report improvements in autoimmune conditions, joint pain, and skin health.
Mental clarity and focus – Some claim enhanced cognitive function and better energy levels.
Digestive health – By eliminating fibre, some find relief from IBS and bloating.
Testosterone support – Higher intake of animal fats and proteins may contribute to better hormonal balance in men.

But is there science to support these claims? Let’s look at the research.

THE SCIENCE BEHIND THE CARNIVORE DIET

WEIGHT LOSS & METABOLIC HEALTH

The high-protein content of the carnivore diet can promote weight loss by:

Increasing satiety hormones (GLP-1 and PYY), making you feel fuller for longer.
Boosting metabolism, as protein has the highest thermic effect of all macronutrients.

A 2021 study in the American Journal of Clinical Nutrition found that high-protein diets lead to increased fat loss and muscle retention, even without calorie counting.

2. INFLAMMATION & AUTOIMMUNE CONDITIONS

Many proponents of the carnivore diet claim a drastic reduction in inflammatory conditions such as arthritis, eczema, and autoimmune disorders.

A 2023 study in Frontiers in Immunology highlighted that eliminating plant antigens and lectins (which are found in many vegetables and grains) may reduce systemic inflammation.
However, long-term studies are lacking, and the role of fibre and antioxidants in reducing inflammation is well-documented.

3. GUT HEALTH & DIGESTIVE DISORDERS

Many report relief from IBS, bloating, and leaky gut syndrome on a carnivore diet.
However, the absence of fibre may lead to changes in gut microbiome composition, which could have long-term consequences.
A 2022 study in Nature Metabolism found that fibre is essential for gut bacterial diversity, which plays a role in immune regulation and metabolic health.

TESTOSTERONE & HORMONAL BALANCE

For men, one of the most compelling reasons to try the carnivore diet is its potential impact on testosterone levels.

Cholesterol and dietary fat are essential for testosterone production, and a high-fat diet has been linked to increased testosterone.
A 2020 study in the Journal of Clinical Endocrinology & Metabolism found that men who consumed more saturated fats from red meat and eggs had higher testosterone levels than those on low-fat diets.
However, long-term effects on cardiovascular health need to be considered.

POTENTIAL RISKS OF THE CARNIVORE DIET

NUTRIENT DEFICIENCIES

By eliminating plant foods, there’s a risk of missing out on:

Vitamin C – Essential for collagen production and immune function.
Magnesium – Important for muscle function, sleep, and heart health.
Fibre – Crucial for gut microbiome diversity and long-term metabolic health.

HEART DISEASE CONCERNS

The high intake of saturated fats raises concerns about long-term heart health.

A 2023 study in Circulation found that diets high in red meat may increase cardiovascular risk, but other factors (such as metabolic health and inflammation) play a role.

LONG-TERM SUSTAINABILITY

The restrictive nature of the diet makes it difficult to follow long-term.
Social limitations – Dining out and variety in meals can be challenging.
Lack of research – Most studies on low-carb and ketogenic diets do not fully apply to carnivore, and long-term data is limited.

WHO MIGHT BENEFIT FROM THE CARNIVORE DIET?

The carnivore diet may be worth exploring for individuals dealing with:

Severe autoimmune conditions that worsen with plant foods.
IBS, Crohn’s disease, or other gut sensitivities.
Men looking to optimise testosterone levels naturally.
Individuals who thrive on a low-carb, high-protein approach.

However, for most people, a balanced diet that includes high-quality animal protein, healthy fats, and nutrient-dense plant foods may offer more long-term benefits.

FINAL THOUGHTS: IS THE CARNIVORE DIET WORTH TRYING?

The carnivore diet challenges traditional nutritional guidelines and offers potential benefits for weight loss, inflammation, and hormone balance. However, long-term health implications remain uncertain.

As a men’s health specialist, my approach is always personalised—what works for one person may not work for another. If you’re considering the carnivore diet, I recommend:

Starting with a modified approach—include eggs, dairy, and some nutrient-dense plant foods.
Monitoring your blood markers—testosterone, cholesterol, inflammation levels, and micronutrients.
Listening to your body—adjust based on energy levels, digestion, and performance.

The best diet is the one that supports your long-term health, vitality, and well-being.
