How Many Eggs Should You Really Eat Per Day?

Eggs and Cholesterol: What the Latest Trials Actually Show

For decades, eggs have swung in and out of dietary favor — cholesterol villain one decade, protein powerhouse the next. The research picture is more nuanced than either extreme, and the right answer depends more on who’s eating than on a single universal number.

The Short Answer

About 1 egg per day (up to roughly 7 per week) is the range best supported by randomized controlled trial evidence for healthy adults. For many people without existing metabolic conditions, even up to 2 eggs/day has held up fine in trials — provided the rest of the diet isn’t heavy in saturated fat.

What the Trial Data Actually Shows

A meta-analysis of 28 randomized controlled trials found egg consumption modestly raised total cholesterol and LDL-C — but it also raised HDL-C, with no change in the LDL:HDL ratio or triglycerides, and no dose-response relationship with the number of eggs eaten.

More importantly, a 2025 randomized cross-over trial isolated the real culprit: saturated fat, not dietary cholesterol from eggs, was the key driver of LDL elevation. Replacing a high-saturated-fat/low-egg diet with a low-saturated-fat diet that included 2 eggs/day actually lowered LDL cholesterol

Bottom line from RCTs: what surrounds the egg on your plate matters more than the egg itself.

So, How Many Eggs Per Day?

There’s no single official cutoff, but here’s how the evidence breaks down by group:

Healthy adults, no dyslipidemia or diabetes: 1–2 eggs/day appears safe. One trial specifically tested 2 eggs/day, 6 days a week (~12/week) against a low-egg comparator and found the higher-egg arm did not worsen lipid profiles.

Existing dyslipidemia, diabetes, obesity, or hypertension: Staying closer to 1 egg/day is the more conservative, better-supported choice. Some cohort data flags intake of 2+ eggs/week as associated with elevated diabetes risk in this population — though this is observational and hasn’t established causation.

What matters more than the number: Overall saturated fat intake. If eggs are replacing bacon and butter, they’re likely a net positive. If they’re piled on top of an already high-saturated-fat diet, the picture changes.

The Practical Takeaway

For most healthy adults, 1 egg a day is a safe, well-supported baseline — and even up to 2/day appears fine for many people, as long as the rest of the diet isn’t heavy in saturated fat. If you have diabetes or high cholesterol, staying closer to 1/day is the more cautious approach, at least until your clinician weighs in on your specific lipid and glycemic picture.
