Skipping breakfast is associated with a significantly higher risk of incident coronary heart disease (CHD) in men, independent of diet quality and lifestyle factors.

For men, consistently skipping breakfast is linked to a higher risk of heart disease. While this doesn't mean you must eat immediately upon waking, maintaining a regular breakfast habit appears protective for cardiovascular health, potentially by stabilizing metabolic markers like blood pressure and cholesterol.

GoodSupportsHIGH confidence
Men who skipped breakfast had a 27% higher risk of CHD compared with men who did not (relative risk, 1.27; 95% confidence interval, 1.06–1.53).
