Over the past decade, the low-carb movement has evolved from a fringe lifestyle into a global wellness phenomenon. From ketogenic diets to the emerging carnivore trend, people everywhere are discovering that cutting carbs and focusing on nutrient-dense foods can deliver powerful results for body and mind.
But as new research unfolds, questions arise about plant-based nutrition, anti-nutrients in vegetables, and how animal-based diets may affect long-term health, hormones, and mental well-being.
To explore these topics, we sat down with Maria Emmerich, an internationally renowned nutritionist and author of best-selling keto cookbooks, to discuss the truth behind low-carb transformations, carnivore vs keto, and the science connecting food and mental health.
The Nutrient Density Revolution
Modern nutrition is shifting away from calorie counting toward nutrient density prioritizing foods that deliver the most vitamins, minerals, and amino acids per bite.
Animal-based foods like organ meats, eggs, and fatty fish rank among the most nutrient-dense foods on earth, providing essential nutrients like vitamin B12, iron, zinc, and omega-3 fatty acids in highly absorbable forms.
“Organ meats are nature’s original multivitamins,” says Maria Emmerich. “Just a few ounces of liver provide more nutrition than most plant-based meals combined.”
This renewed focus on nutrient density has fueled the popularity of both keto and carnivore lifestyles, each aiming to reduce processed carbs and optimize metabolic health through whole, unprocessed foods.

Carnivore vs Keto: What’s the Difference?
While both diets eliminate refined carbohydrates, they differ in scope and flexibility.
The Keto Diet: Focuses on a high-fat, moderate-protein, very low-carb approach. It allows for some plant foods like leafy greens, nuts, seeds, and low-sugar fruits. The goal is to maintain nutritional ketosis, where the body burns fat for energy instead of glucose.
The Carnivore Diet: Takes keto to the extreme cutting out all plant foods and focusing exclusively on animal products such as meat, fish, eggs, and dairy. It’s essentially zero-carb.
“Think of keto as a metabolic strategy and carnivore as an elimination diet,” explains Maria Emmerich. “Many people start with keto and move to carnivore to identify food sensitivities or improve digestion.”
The Debate: Anti-Nutrients in Vegetables
Vegetables are widely celebrated for their antioxidants and fiber but they also contain compounds known as anti-nutrients, which can interfere with the absorption of minerals like iron, zinc, and calcium.
Examples include:
Oxalates (in spinach and almonds)
Phytates (in grains and legumes)
Lectins (in beans and nightshades)
Goitrogens (in cruciferous vegetables like kale and broccoli)
For most people, these compounds are harmless or even beneficial in small amounts. However, those with autoimmune or digestive issues may find relief by reducing them which is one reason some people thrive on a carnivore or animal-based diet.
“Anti-nutrients aren’t a problem for everyone,” says Emmerich. “But if you’re struggling with inflammation or poor gut health, temporarily removing them can be a powerful diagnostic tool.”
Keto for Mental Health: A Growing Field
One of the most exciting frontiers of nutrition research involves keto for mental health. Studies now show that ketogenic diets can help stabilize mood, enhance focus, and even support recovery from depression and anxiety.
When glucose levels fluctuate, so does brain chemistry. Ketones the alternative fuel produced in ketosis provide a steady, clean energy source for the brain, improving mental clarity and reducing mood swings.
Emerging evidence even supports keto’s role in neurological conditions like bipolar disorder, epilepsy, and Alzheimer’s disease.
“Brain fog, depression, and anxiety are often tied to metabolic dysfunction,” says James Kim of Ravoke. “By restoring energy balance, the keto diet can dramatically change how people feel both physically and emotionally.”
Keto for PCOS and Hormonal Health
The benefits of keto for PCOS (Polycystic Ovary Syndrome) are equally compelling. PCOS is strongly linked to insulin resistance, and low-carb diets help regulate blood sugar and improve hormonal balance.
Studies have shown that women with PCOS who adopt a ketogenic or low-carb lifestyle experience:
Improved insulin sensitivity
Reduced androgen levels
Better ovulation and fertility outcomes
Sustainable weight loss
“Nutrition is medicine,” emphasizes Maria Emmerich. “Keto gives women with PCOS the metabolic reset they need to restore hormonal balance naturally.”
Carnivore Diet Benefits and Low-Carb Transformations
The carnivore diet benefits extend beyond simplicity and satiety. Supporters report relief from autoimmune symptoms, improved digestion, reduced inflammation, and consistent weight loss.
Because it eliminates plant irritants and carbohydrates, the carnivore diet helps stabilize blood sugar, reduce bloating, and enhance nutrient absorption.
Across social media, countless low-carb transformation stories highlight dramatic improvements in both physical and mental well-being. People describe reversing type 2 diabetes, shedding stubborn fat, and overcoming chronic fatigue simply by returning to whole, ancestral foods.
Organ Meats: The Forgotten Superfood
Organ meats — liver, heart, and kidneys — are the unsung heroes of the carnivore and keto movements. Often overlooked in modern diets, they’re packed with vitamins A, D, E, K, and B-complex, along with key minerals like selenium and iron.
Liver alone contains:
10x more vitamin B12 than steak
6x more folate than spinach
High levels of retinol (active vitamin A) for vision and immune support
“Organ meats are the original superfood,” says Emmerich. “If people ate more of them, we’d see far fewer deficiencies and a stronger immune system overall.”
The Power of Real-Life Success Stories
Among the most inspiring aspects of the keto and carnivore communities are the real-life success stories — people who reclaim their energy, confidence, and health after years of struggle.
From weight loss transformations to mental clarity breakthroughs, these testimonials remind us that food is not just fuel; it’s medicine.
One keto diet success story featured by Ravoke shared how a 42-year-old woman reversed chronic depression and insulin resistance within six months of adopting a ketogenic lifestyle. Her doctor later confirmed normalized blood sugar and improved cholesterol levels all without medication.
Balancing Safety and Sustainability
Despite their benefits, both keto and carnivore diets require careful monitoring. Nutrient deficiencies, electrolyte imbalances, and digestive adjustments are common during the first few weeks.
Experts recommend:
Getting regular blood tests for cholesterol, electrolytes, and nutrient levels
Including a variety of animal-based foods, especially organ meats
Consulting a healthcare provider if you have pre-existing conditions
“Keto and carnivore can be powerful healing tools,” says Maria Emmerich, “but they must be approached mindfully, with respect for your body’s feedback.”
Final Thoughts: Food as Medicine
The evolution from keto to carnivore isn’t about restriction it’s about rediscovery. Rediscovering the power of real food, the wisdom of ancestral eating, and the connection between diet and mental well-being.
Whether you lean plant-based, low-carb, or fully carnivore, the goal remains the same: nourish your body with nutrient-dense foods that support energy, balance, and long-term health.
