Dr. Philip Ovadia, a heart surgeon who has operated on thousands of hearts, addresses the common concern about cholesterol levels among those on the carnivore diet. He aims to provide a straight answer on whether eating only meat will clog arteries and shorten life, based on his direct experience with human arteries.
Dr. Ovadia recounts how he initially believed the standard story that cholesterol causes heart disease, but his observations in the operating room revealed inconsistencies. He frequently saw patients with normal cholesterol levels suffering from massive heart attacks, and others with high LDL but clean arteries, leading him to question the established paradigm.
Through thousands of cases, Dr. Ovadia identified chronic inflammation, metabolic dysfunction, damaged artery walls, insulin resistance, and high blood sugar swings as the true problems. He compares cholesterol to a firefighter responding to an existing 'fire' (artery injury), not the cause of the fire itself. Cholesterol only builds up if the injury persists.
While many on a carnivore diet see their LDL and total cholesterol rise, Dr. Ovadia explains this is often a marker, not a cause, of disease. On a carnivore diet, the body makes more cholesterol due to the absence of plant toxins and processed carbs, while inflammation drops, triglycerides plummet, HDL rises, and blood sugar stabilizes. These metabolic improvements are what truly matter.
Dr. Ovadia shares his personal journey of losing nearly 100 lbs and reversing metabolic issues on a low-carb, mostly carnivore diet. He notes that patients who improve their metabolic health through carnivore or similar diets show less plaque progression and improved coronary artery calcium scores, despite potentially higher LDL levels.
He emphasizes that carnivore isn't a magic bullet for everyone, especially those with genetic conditions like familial hypercholesterolemia or other risk factors like smoking. He advises patients to get comprehensive lab tests, including fasting insulin, hemoglobin A1C, triglycerides, HDL, hsCRP, and a coronary artery calcium scan, rather than solely focusing on LDL.
Dr. Ovadia recommends stop fearing red meat, getting the full range of metabolic labs, considering a coronary artery calcium scan, and monitoring progress every 3-6 months if on a carnivore diet. He also stresses the importance of working with a doctor who understands metabolic health over one solely focused on LDL, and encourages critical thinking about medical advice.
His ultimate goal is to help people avoid surgery by understanding and addressing the real causes of heart disease. He advocates for informed decisions based on observed arterial health rather than outdated cholesterol fears, highlighting that diet changes can empower individuals to lead healthier, longer lives.
