Dr. Philip Ovadia explains that cholesterol is often misunderstood. It plays a role in repairing blood vessel damage but is not the root cause of heart disease. He advocates for a high-fat diet, combined with animal protein, to improve heart disease, contrasting it with common medical advice to avoid saturated fats and red meat.
Dr. Ovadia, having performed over 3,000 heart surgeries, states that heart disease is largely preventable and that the current medical system often fails patients by not providing adequate information for prevention. He argues that the disease should not progress to the point of needing invasive surgery or stents, as its true causes are known and reversible.
Cholesterol found in plaque is part of the repair process for damaged blood vessels. The problem arises when cholesterol becomes dysfunctional (oxidized LDL, small dense LDL, vLDL), leading to an inflammatory reaction and plaque buildup. Focusing on what damages the blood vessels, rather than cholesterol itself, is the correct approach.
Dr. Ovadia advises patients to request an advanced lipid panel, also known as an NMR panel or lipo fractionation, to understand the type and size of LDL particles. He clarifies that large, healthy LDL particles are beneficial, while smaller, dysfunctional ones are problematic. For those unable to access these tests, he suggests focusing on inflammation and insulin resistance markers.
For individuals on ketogenic or carnivore diets, an increase in LDL cholesterol can occur as the body adapts to burning fat for energy. This often involves an increase in large, buoyant LDL particles, which are not problematic. An advanced lipid panel can confirm this, along with other indicators like low C-reactive protein (CRP), normal uric acid, and ferritin levels, to ensure overall health.
Dr. Ovadia indicates statins have a small benefit primarily for insulin-resistant individuals unwilling to make lifestyle changes. He highlights two major long-term side effects: increased insulin resistance (worsening the root cause of heart disease) and neurocognitive issues. He stresses that statins often provide a false sense of security, as many patients on statins still end up needing heart surgery.
Insulin resistance is identified as the absolute root cause of heart disease. It contributes through several pathways: elevated blood sugar damaging vessels, decreased nitric oxide (a protective chemical for blood vessels), and systemic inflammation. Dr. Ovadia points out that studies from the 1960s and 70s already showed nearly all heart disease patients have insulin resistance.
Dr. Ovadia emphatically states that red meat and butter do not cause heart disease; they don't cause insulin resistance or inflammation. He challenges the notion that saturated fats are harmful, saying it has been disproven. He highlights that these healthy fats, especially animal fats, can help reverse heart disease.
A high-fat diet, specifically using natural animal fats and minimally processed fruit fats (like coconut, avocado, olive oil), combined with animal protein, has been shown to improve heart disease. Foods like beef, eggs (especially pasture-raised), and lamb are highly recommended. Raw milk and raw cheese are also considered beneficial. Honey can be incorporated in moderation by insulin-sensitive and active individuals.
Real, unprocessed salt has no limit for those seeking to fix heart disease, as opposed to processed salts found in junk food. For those including vegetables, Dr. Ovadia advises tailoring carbohydrate intake based on individual insulin sensitivity and activity levels, recommending tools like continuous glucose monitors. Fasting is also presented as a powerful tool to encourage ketogenic metabolism and reduce visceral fat.
Triglycerides are a better marker for heart disease risk than LDL. Levels under 100 mg/dL and a triglyceride-to-HDL ratio less than 1.5 are ideal. Fasting insulin is crucial, with desired levels under 7 (ideally 3-5). The Coronary Artery Calcium (CAC) scan directly measures plaque, offering a more accurate assessment than cholesterol levels. The CT angiogram provides even more detailed imaging but involves higher radiation.
The timeline for reversing heart disease varies, but the primary goal is to halt its progression by addressing insulin resistance and inflammation. Improvement can be seen within months to a few years. Even if complete reversal isn't possible (e.g., in long-standing type 2 diabetes with accumulated damage), significant improvement in health markers and quality of life is achievable.

The primary culprits behind heart disease are ultra-processed carbohydrates and sugars (like bread, pasta, cereals), industrial seed oils (vegetable oils, canola oil), fake heart-healthy foods (like margarine), and alcohol. These foods contribute to insulin resistance and inflammation, directly damaging blood vessels. Dr. Ovadia stresses the importance of reading ingredient lists and avoiding artificial additives.
