This advice is based on a modern understanding of lipid regulation, validated by several meta-analyses and systematic reviews (e.g., Berger 2015, Fernandez 2022) which show the absence of a significant direct correlation between ingested cholesterol and cardiovascular risk. Research confirms that the body regulates its own cholesterol level, notably through hepatic compensation: when exogenous intake increases, endogenous production decreases. Peter Attia rightly emphasizes that the impact of dietary cholesterol is generally weak and highly variable depending on the individual (with 'hyper-responders' being a minority). However, it is crucial not to confuse dietary cholesterol with saturated fats, which can influence LDL lipoprotein levels in many people. The distinction made between dietary cholesterol and blood levels is therefore scientifically sound and reflected in the evolution of public health recommendations, such as those of the American Heart Association.

What the graded evidence says

Evidence: B

Linked to, not proven to cause.

Effect: cardiovascular disease risk by egg / dietary-cholesterol intake (pooled cohorts) — up to ~1 egg/day not associated with CVD risk overall (pooled HR near 1.0); a separate cohort found each additional ~300 mg/day dietary cholesterol and each half-egg/day associated with modestly higher CVD and all-cause mortality
Measured on: generally healthy adults; some signal of greater sensitivity in diabetes

This is association data (cohorts), not proof, and it's slightly mixed: most analyses clear moderate egg intake, one large one flags dietary cholesterol. 'Up to 7 a week is harmless for everyone' is a fair rule of thumb for healthy people, with a gentle caveat for diabetes.
