The Great Breakfast Debate: Eat or Skip?

Dear readers,

The news exploded this week because of a presentation at the American Heart Association’s Scientific Sessions 2024 identifying a higher risk of death in those who eat in an 8-hour window and skip breakfast. The data has yet to be published and was analyzed by a university in Shanghai using a US database, NHANES. I included 3 other studies that found the same association. I recommend eating in an 11-12 hour window and including a healthy breakfast.

In addition, the US Food and Drug Administration recently announced it is removing its campaign of ivermectin use as an off-label COVID-19 treatment to inhibit doctors and the public from considering this therapy. The first non-statin drug to achieve labeling for the primary prevention of cardiovascular disease, bempedoic acid, was announced. However, it is an expensive choice with a sometimes tricky approval process. Healthy bones in those following plant-based diets were reported. The role of C15, a unique and perhaps essential fatty acid, was also reported in a trial in Asian women. Finally, sitting for prolonged periods may be associated with erectile dysfunction.

Be well,
Joel Kahn, MD, FACC

      • Restricting eating to a brief 8-hour window daily could result in a higher risk of death from heart attack and stroke, according to a new study.
      • Researchers report that people who practice this time-restricted eating plan also had poorer outcomes if they had existing cardiovascular disease or cancer.
      • This study was observational, so it is hard to draw definitive conclusions, but it does add to the growing body of studies on the pros and cons of time-restricted eating.

    • Previous research has identified genetic variants linked to sedentary leisure behavior, which includes activities such as watching television, using a computer, and operating a vehicle. In a new analysis published in Andrology, a higher genetic susceptibility to leisure computer usage was associated with a greater risk of erectile dysfunction in men.
