How it works
Our scientific basis: Return to the Optimal Human Diet (OHD)
At Mevis, we base our therapeutic approach on anthropological, bioarchaeological, and evolutionary studies that reveal how humans have eaten for most of their history. This scientific evidence, unencumbered by modern dietary fads, clearly shows us what type of diet allowed our species to develop, adapt, and thrive over millennia.
What do anthropology and bioarchaeology tell us?
Analysis of bone remains, tools, hunting and migration patterns, along with studies of present-day non-industrialized tribes, allows us to reconstruct the Optimal Human Diet (OHD): a diet rich in animal fats and proteins, with very little or no processed carbohydrates, sugars, and industrial vegetable oils.
This dietary model is consistent with our physiology, genetics, and evolution, and stands in stark contrast to the modern diet, which is loaded with ultra-processed foods, additives, refined flours, and hidden sugars. This modern, artificial, and historically recent diet has proven to be suboptimal and incompatible with human metabolic health.
A sick species
The consequences of this diet, which is misaligned with our biology, are increasingly evident: chronic diseases, degenerative disorders, hormonal imbalances, mental health problems, obesity, infertility, type 2 diabetes, cancer, among many other conditions that affect millions of people today.
Traditional medicine often treats the symptoms, but rarely questions the origin of these diseases. At Mevis, we do.
Back to basics: eating like humans
We firmly believe that healing begins when we give the body back the nutrients it needs, in the way we evolved to assimilate them. The Optimal Human Diet (OHD) is not a fad: it is a recovery of ancestral knowledge validated by current science.
When we eat properly—with real, nutrient-dense food, focused on quality animal foods, and accompanied by physiological fasting—the body can return to its natural state of balance and healing. That's the heart of our work.
What is Mevis
Mevis is a multidisciplinary team of professionals dedicated to the holistic healing of people facing metabolic and chronic diseases. We specialize in metabolic therapies based on ketogenic nutrition, elimination diets such as the carnivore diet, and various fasting modalities, both intermittent and prolonged, tailored to each person's individual goals and needs.
Our Mission
Healing and transforming lives through a holistic approach based on nutrition, fasting, physical and mental well-being, and connection with nature. We offer a virtual care model, providing effective tools for preventing and reversing metabolic diseases and improving physical and cognitive performance.
How we work
Treatments are performed 100% virtually, through personalized sessions, ongoing follow-up, and a dedicated mobile app that allows for:
Schedule appointments.
Access educational content in video and documents.
Participate in supportive communities and social networks.
Choose between free programs or paid memberships.
Our plans include intensive nutritional counseling and lifestyle changes that aim to restore the body's natural rhythms. We base our approach on:
Low-carb diet (ketogenic or carnivore diet).
Therapeutic fasts adapted to each objective (intermittent, prolonged, etc.).
Complementary biohacking practices: cold immersion, conscious breathing (Wim Hof Method), meditation and mindfulness.
Our experience
We have over a decade of experience helping hundreds of individuals, families, and groups of friends transform their health in just a few weeks. Many of them have reversed conditions that were considered incurable by traditional medicine.
At Mevis, we don't just treat illnesses: we teach you how to live with fulfillment, energy, and mental clarity.
