If you’ve spent more than five minutes on TikTok or Instagram looking at health content lately, you’ve probably seen a high-energy man with silver hair shouting about how fruit is "mierda" (crap) and chicharrón is a superfood. That’s Jorge Enrique Bayter Marín. Or, as his millions of followers know him: Doctor Bayter.
The guy is polarizing. One day he’s telling you that your morning oatmeal is a slow-motion suicide attempt, and the next, he’s showing off a plate of fatty pork belly as the pinnacle of human nutrition. Naturally, when someone starts attacking the "sacred" food pyramid this aggressively, people start asking the big question: is Dr Bayter a real doctor? It's a fair thing to wonder. In an era where anyone with a ring light and a white coat from Amazon can give medical advice, checking credentials isn't just cynical; it’s survival.
Let’s look at the actual credentials
Let’s skip the drama for a second and look at the paperwork. Jorge Enrique Bayter Marín is, in fact, a real physician. He isn't a chiropractor or a PhD in "holistic wellness" trying to pass as a medical doctor. He is a trained MD from Colombia.
Specifically, he is an Anesthesiologist and Intensive Care Specialist.
This is a detail that surprises people. Most "influencer doctors" come from family medicine or dermatology backgrounds. Bayter spent years in the trenches of the ICU (Intensive Care Unit). He’s used to dealing with patients on the brink of death—people whose bodies are failing because of metabolic syndrome, out-of-control diabetes, and cardiovascular collapse.
- Medical Degree: MD from a recognized Colombian institution.
- Specialty: Anesthesiology.
- Sub-specialty: Critical Care/Intensive Care (Intensivista).
- Registration: He holds a valid medical registration (RM 0717-95) in Colombia.
So, when you ask if Dr Bayter is a real doctor, the technical answer is a hard yes. He has the degrees. He’s seen the inside of a human heart. He’s managed ventilators. He isn't just a guy who read a blog about keto and decided to start a YouTube channel.
Why all the controversy then?
If he’s a real doctor, why is the medical community constantly side-eyeing him?

The friction doesn't come from his degree; it comes from his Methodology (Method DKP) and his delivery. Bayter doesn't just suggest a low-carb diet. He goes to war with carbohydrates. He calls fruit "poison" because of the fructose content. He claims that the modern medical system is essentially keeping people sick to sell them pills.
This is where things get messy. Most mainstream nutritionists and the World Health Organization (WHO) will tell you that fruit is part of a balanced diet. Bayter argues that for a "sick" person—someone with insulin resistance or a fatty liver—fruit is just more fuel for the fire.
He’s basically the "bad boy" of the medical world. He uses colorful language, he gets angry, and he’s incredibly dogmatic.
"I didn't become a doctor to tell you what you want to hear. I became a doctor to stop you from dying in my ICU."
That’s essentially his brand. It’s effective. It’s also why many traditional doctors find him dangerous. They worry people will take his advice too literally and stop eating all fiber or start consuming excessive amounts of saturated fat without understanding their own blood markers.
The Miami connection and the "Doctor Bayter LLC"
You might have noticed he spends a lot of time in the US now. There’s a Doctor Bayter LLC registered in Florida. He isn't necessarily practicing as a bedside intensivist in Miami (licensing for foreign doctors in the US is a brutal, multi-year process involving the USMLEs). Instead, he’s operating as a health consultant and content creator.

This is a key distinction. In Colombia, he is a licensed, practicing physician. In the US, his online presence is more about "educational health coaching." It’s a legal tightrope many international doctors walk.
Is his advice actually safe?
This is where you have to use your own brain.
Bayter’s core message is about Metabolic Flexibility. He wants your body to burn fat for fuel instead of constantly spiking insulin with sugar. Science actually backs a lot of this up. We know that sugar is the root of most modern chronic diseases. We know that the "low-fat" craze of the 90s was a disaster.
But—and it’s a big but—his "all or nothing" approach isn't for everyone.
If you have certain genetic markers or gallbladder issues, eating a diet 70% comprised of fat (even "good" fats) could send you to the hospital. Bayter often focuses on the "perfect keto" (Dieta Keto Perfecta). He isn't a fan of "dirty keto" with processed oils and sugar-free chemical snacks. He wants real, whole foods.
What most people get wrong about him
People think he’s just a "keto guy."

Honestly, he’s more of an anti-inflammation guy. He hates anything that causes systemic inflammation. That’s why he hates vegetable oils (seed oils), gluten, and processed sugars. He views the human body as a high-performance machine that we are currently fueling with cheap, toxic sludge.
His bedside manner? Non-existent.
His energy? Intense.
His medical license? Real.
How to verify him yourself
If you're still skeptical, you don't have to take a blog's word for it. You can look up medical registries in Colombia or check his affiliations with various aesthetic and intensive care congresses where he has been a speaker. He’s been around for over 20 years. He didn't just appear out of nowhere during the pandemic.

Actionable steps for your health
If you're following Dr. Bayter or thinking about it, don't just dive into a pile of bacon because a man on TikTok told you to.
- Get your bloodwork done first. Know your ApoB, your fasting insulin, and your Lp(a). Bayter himself often yells at people to "check your exams" before arguing with him.
- Don't ignore the nuances. If you're an elite athlete, your carb needs are different than a sedentary person with Type 2 diabetes.
- Consult a local professional. If you're going to make a radical lifestyle change, find a keto-friendly or functional medicine doctor in your area who can monitor your kidneys and liver.
Is Dr Bayter a real doctor? Yes. Is he right about everything? That’s for you and your blood tests to decide. Just remember that in medicine, "absolute truths" are rare, and what works for a patient in an ICU in Medellin might need tweaking for you.
Next Steps for You:
If you're looking to verify more medical influencers, you should start by checking the state or national medical board in their country of origin. For US-based doctors, the DocInfo portal by the Federation of State Medical Boards is the gold standard for checking if someone actually has a license to practice.
