The egg studies are not wrong.

They are measuring the wrong people.

A flaw called the ceiling effect, and what it has been hiding for thirty years.

Hi friend

The studies look reassuring. An egg a day barely moves your cardiovascular risk, small enough that most physicians will tell you one a day is fine.

So why won't I eat one?

Because of a measurement problem called the ceiling effect. Once you understand it, you can see why almost every egg study ever published was structurally unable to detect the risk it set out to measure. The people most harmed by dietary cholesterol turn out to be precisely the people for whom eggs are most often recommended.

• Why eggs may be more dangerous for people who are overweight or insulin resistant, and why that describes most of the people eating them

• What the cholesterol in a yolk may do during pregnancy, and why it connects to the test your obstetrician keeps running

• The protein and choline arguments, and where both are easier to get without the egg

“If you smoke two packs a day, adding a third barely changes your measured risk. That does not make the third pack safe. It means you were already at the ceiling. The egg studies have exactly the same problem.”

The goal of the Eat to Live Podcast is to give you the actual research — not the headline version of it. I hope this episode changes how you read the next egg study you come across.
