Cholesterol Confusion: Why am I still alive? with Dr Nick Norwitz

Summary

Dr. Nick Norwitz discusses how cholesterol results can mean different things depending on a person’s underlying health and metabolism. He uses his own experience to argue for individualized assessment, while emphasizing that his case should not be simplified into “cholesterol doesn’t matter” or “don’t take statins.”

Key points

• His personal case: Norwitz says his total cholesterol reached about 700 mg/dL after he adopted a ketogenic diet to manage ulcerative colitis. He reports that a coronary CT angiography found no measurable plaque. He presents this as an unusual case, not proof that very high cholesterol is harmless.
• Cholesterol in context: He argues that the same cholesterol level may arise from different causes, such as an inherited disorder or a change in how the body transports and uses fuel. He cautions against treating one lab measurement as a complete picture of cardiovascular risk.
• Diet and cholesterol response: Norwitz describes a meta-analysis of 41 randomized trials in which lower starting BMI was the strongest predictor of LDL increases on low-carbohydrate diets. He proposes that some lean people on these diets may transport more fat in cholesterol-containing particles. This is presented as a possible explanation, not a universal rule.
• The “Oreo experiment”: In a personal crossover experiment, he compared statins with Oreo cookies and reported that adding the cookies rapidly lowered his cholesterol. He stresses that Oreos are not healthy food and that the experiment does not establish what anyone else should eat or do.
• Statins and evidence: He argues that statins’ effects may extend beyond LDL reduction, including possible anti-inflammatory benefits. He discusses research suggesting potential effects on GLP-1, mitochondria, and fatty-acid metabolism, as well as possible differences in side effects between women and men. He says these findings need further investigation and should be considered alongside established evidence and individual circumstances.
• Personalized care: His central message is to consider a person’s overall metabolic health, risk factors, and clinical context rather than relying on a single threshold. He advocates open discussion of uncertainties and weighing the potential benefits and trade-offs of treatment with a clinician.
• Inflammation and sleep: In response to a question about inflammation, he notes that statins may have anti-inflammatory effects in some people. He also describes animal research suggesting a possible pathway linking sleep deprivation, inflammatory cells, and heart disease. This supports taking sleep seriously, though the mechanism discussed is not presented as settled human evidence.
• Other possible approaches discussed: He mentions small or preliminary studies in which TUDCA appeared to reverse some statin-associated metabolic changes, and preclinical work in which fish oil may counter certain effects discussed in women. These are research leads, not recommendations for self-treatment.
• Practical wellness tip: A speaker says they encourage employees to do squats every half hour.
