Is eating only meat the future of optimal health, or is it just another extreme dietary trend skating on the edge of controversy?
The carnivore diet—a regimen that eliminates everything but animal products—has surged in popularity, fueled by testimonials of dramatic weight loss, reversed chronic conditions, and sharper mental clarity.
Supporters claim it’s a return to humanity's ancestral roots, while critics question its sustainability, nutritional adequacy, and long-term health implications. To examine this polarizing topic, I want to help cut through the noise to present a balanced analysis that offers insights for both skeptics and supporters.

A Hunter-Gatherer Throwback or Modern-Day Fad?
Human history is sprinkled with evidence of predominantly meat-based diets. Archeological findings suggest that ancient hunter-gatherer diets heavily relied on animal products during eras of scarcity, shaping the evolution of our omnivorous digestive systems. However, the modern carnivore diet goes a step further, cutting out plant-based foods entirely. This raises valid concerns about how it aligns—or clashes—with our evolutionary roots.
Another valid concern with this predominantly meat based approach is the assumption that our ancestors ahered to one universal diet. This is absolutely not the case and we can simply look at the diversity in food availability and produce (even in an ever more connected world) to recognise that access to, and sources of food, would have been much different depending on geographical position.
The Science of the Carnivore Diet (and What We Don’t Know Yet)
Metabolic Health and Chronic Conditions
Anecdotal reports highlight its use in managing autoimmune conditions, like IBS and IBD, as well as type II diabetes and being an effective weight loss approach. However, critics rightly point out the lack of data on the diet, particularly long-term, large-scale studies that evaluate its safety and efficacy over time. Without data spanning decades, we’re simply guessing about its sustainability for lifelong health.
Cholesterol and Heart Health
Few topics stir debate like the effect of the carnivore diet on cholesterol levels. Adherents report improved triglyceride-to-HDL ratios—a marker associated with better cardiovascular health.
Yet, for some, LDL cholesterol levels spike dramatically on a meat-exclusive diet. This has been brushed off as unimportant by many advocates who go as far to say LDL being a risk factor for heart disease and cardiovascular events is a myth. While it's true that LDL may not be the sole factor in these issues manifesting, you can't ignore the strong link associated with these events and the fact that LDL is part of the constellation of risk factors associated with an increased risk of these health issues.
Many questions remain unanswered, including the context of these changes and whether they translate to actual cardiovascular risks of course but it's ridiculous to go so far the other way that you openly proclaim changing cholesterol levels and overall profile as being insignificant to a person's health.
Gut Microbiota and Dietary Diversity
One overlooked aspect is the impact of a zero-fiber diet on gut microbiota composition. Advocates suggest fiber isn’t necessary for gut health, pointing to anecdotal evidence that digestive distress disappears on a meat-only diet.
Critics argue that the carnivore approach eliminates diverse pre- and probiotics crucial for a flourishing gut microbiome. Here, science is far from settled, but the trade-offs warrant careful consideration.
The Ethical and Environmental Conundrum
Promoting a carnivorous lifestyle in an era of climate crisis is not without its challenges.
Critics cite data pointing to animal agriculture’s environmental toll; from greenhouse gas emissions to deforestation. Conversely, proponents argue that ethically raised, grass-fed livestock can have a smaller environmental footprint than the resource-heavy monocropping required for plant-based products like soy and almond milk.
It’s clear that individual choices, regional practices, and personal circumstances play a huge role in determining the true impact of a carnivore diet.
For skeptics, the environmental concerns remain a sticking point, while supporters emphasize mindful sourcing to mitigate those challenges. Again, with this argument, both "tribes" are approaching this from the extreme of their position. Carnivore diets are not going to become the universal norm so our entire food system won't be shifting and potentially furthering it's contributions to climate change.
Conversely, I find it hard to believe that all carnivore diet followers source their foods from local farmers with a minimal environment footprint. That doesn't mean that some don't but it would be impractical (and not also feasible depending on where the person lives) to always source locally.
Red Meat, the central focus of this diet in much of the online debate, has been unjustly villified in recent years. Check out this video we did with MyProtein that gives a fair and balanced insight and overview over red meat and it's potential role in our health.
Stories from the Frontlines of the Carnivore Lifestyle
Success Stories
Countless testimonials extol the virtues of the carnivore diet. From significant weight loss to resolving lingering chronic issues, these personal stories bolster its appeal as a problem-solving dietary approach. Many adherents also highlight psychological benefits such as enhanced mood stability and sharper focus.
Cautionary Tales
However, not everyone gleans untold success. Some individuals report struggles with nutrient deficiencies (including vitamin C and potassium), difficulty adhering to the diet long-term, and friction in social situations due to its unconventional nature. Balancing personal experiences with medical guidance is a non-negotiable step.
Practical Steps for Considering the Carnivore Diet
If you’re curious about the carnivore diet, the following steps can help you safely explore it:
Review Your Goals: Are you considering this for weight loss, management of chronic conditions, or curiosity? Be clear about your motivations.
Consult a Professional: Work with a healthcare provider or a nutritiona professional to assess whether this diet aligns with your health needs and considerations.
Monitor Your Nutritional Intake: A meat-based diet can lack key nutrients like vitamin C, magnesium, and fiber. You may need supplements or strategic food choices (e.g., organ meats).
Start Slow: Transitioning from a mixed diet to carnivore can be a shock. Start by gradually increasing animal products and gauging how your body responds.
Track Changes: Regularly monitor key health indicators like cholesterol levels, inflammation markers, energy levels, and mental clarity. Make data-driven adjustments.
Stay Open-Minded: It’s okay to adapt. If the carnivore diet doesn’t suit you long-term, look for ways to incorporate its principles into a balanced, sustainable model. Add in other whole foods to your diet for sustainability and you'll find that the carnivore diet has served it's role as a stepping stone to a more nutritious, fulfilling overall dietary approach.
Finding Middle Ground in the Debate
The carnivore diet is neither the miracle cure its proponents champion nor the catastrophic trend its detractors fear. It has its merits—particularly as a solution for certain individuals with specific health challenges—and its flaws, especially in terms of nutritional gaps and ecological concerns.
The answer lies not in universal acceptance or outright dismissal but in informed experimentation tailored to individual needs.
A Call to Engage
Ultimately, diets like the carnivore program remind us of one key truth: there’s no one-size-fits-all approach to nutrition. We encourage you to dig deeper, question everything, and share your personal experiences. By fostering an open, informed dialogue, we can collectively reshape how we approach health and wellness.
