The American Day · A Data Story
What happened to
three meals a day?
Breakfast, lunch, dinner. It’s a familiar routine, but it has never described everyone’s day. National food surveys show how that routine has changed—and what people eat around it.

01 / When We Eat
Dinner leaves
the biggest mark.
Drag through the years to see the day change. Each bar covers one hour, including people who ate nothing in that hour. The scale stays fixed.
Calories across the day
U.S. population aged 2+ · Average calories per person
Tap or focus a bar for its breakdown. Each slider step is one of nine surveys.
In 2021–23, first interviews moved to telephone. These are different samples of people; changes in reporting and population mix can affect the comparison. No survey values are invented for the gap after 2017–18.
02 / Which Meal Was Missing?
More people reported
no lunch than
no breakfast.
This counts everyone who reported no food or drink under that meal name, apart from plain water—not just people who ate exactly two meals.
The meal missing from the day
2021–23 · Adults aged 20–74 · Percent reporting no such meal
Both bars run from 0 to 100%. A person missing both meals counts in both bars. “No lunch” doesn’t mean they ate nothing at midday: they may have called it a snack.
03 / The Three-Meal Day
Less universal.
Still common.
A study of American adults found that fewer reported breakfast, lunch, and dinner in 2007–10 than in the early 1970s. Most still reported all three. Someone who ate all three meals plus snacks still counts here.
Who reported all three meals?
Percent of adults aged 20–74 · Published adjusted estimates
The decline was not steady. Reporting fell sharply in the late 1980s and 1990s, then rose in later surveys.
Kant & Graubard, Table 2 ↗04 / Between Meals
Snacks add up.
People chose the names themselves. A drink with lunch counts toward lunch; a separate occasion called “drink” goes in the drinks bar.
A day’s calories, by occasion
2021–23 · U.S. population aged 2+ · Average calories per person
“Other” includes eating spread over an extended period and occasions outside the listed meal, snack and drink categories.
05 / Beyond The Average
One average.
Thousands of different days.
These are individual days, not usual diets. The spread includes differences in age, appetite, how much people remember, and how much they ate that day.

Bins cover 500 calories each. The final, open-ended 4,500+ bin includes every higher report; none are dropped.

Food entries may be ingredients or components of a larger dish. Detail values cover all occasions at that hour, even when a meal filter is selected. Rounded values may differ slightly from their sum.
Sources & Method
What these numbers can tell us.
What people remembered
The CDC asked people to recall everything they ate and drank the previous day, midnight to midnight. Calories were calculated from the foods and amounts they described. These are estimates of reported intake, not targets for what to eat.
What counts as three meals
The adult comparison counts at least one breakfast, lunch and dinner/supper in one recall, whether or not the person also had snacks. It follows the paper’s groupings: brunch counts as lunch and almuerzo as breakfast. Water-only events do not count.
The historical study used adjusted estimates, and interviews changed over time. It cannot establish why eating patterns changed. In 2021–23, first-day interviews were conducted by telephone.
