Key Takeaways
Empty Calories
"Empty calories" refers to foods or drinks that provide energy — measured in calories — but deliver little to no meaningful nutrients such as vitamins, minerals, fiber, or protein. The term is commonly applied to items like sugary beverages, candy, and certain ultra-processed snack foods. It's a useful shorthand in nutrition education, but it can also oversimplify how food quality actually works.
In nutritional science, calorie density and nutrient density are distinct measures; a food can be calorie-dense without being nutrient-poor in every dimension, which is one reason the "empty" label is contested among dietitians.
Where the Term Comes From
The phrase "empty calories" became a staple of nutrition messaging in the mid-twentieth century as public health educators looked for accessible ways to talk about diet quality. The core idea is straightforward: some foods supply the body with energy — calories — while contributing almost none of the other things the body needs to function, such as vitamins, minerals, fiber, or protein.
Sugary sodas are the canonical example. A standard 12-ounce can of cola can deliver more than 150 calories almost entirely from added sugar, with negligible amounts of any micronutrient. Alcohol is another often-cited case — it provides calories through ethanol while supplying essentially no nutritional benefit.
As a teaching concept, the term works well. It gives people a quick way to understand that calories and nutrition are not the same thing. But like many simplifications in health communication, it can be stretched further than the evidence really supports.
Why the Label Gets Complicated
The first complication is that "empty" is rarely absolute. Consider white rice, which nutrition discourse often lumps near the empty-calorie end of the spectrum. It's lower in fiber and certain nutrients compared with brown rice, but it still provides some B vitamins, a small amount of protein, and is a primary caloric staple for billions of people who maintain good health. Labeling it "empty" misrepresents its actual profile.
A second issue is that foods are rarely eaten in isolation. A small amount of candy consumed alongside a meal containing vegetables, legumes, and protein contributes far less meaningful disruption to nutritional status than the empty-calorie label might imply. Nutrition science consistently emphasizes overall dietary patterns over the impact of any single food or ingredient.
Language Shapes How We Eat
The words used in nutrition messaging can influence behavior and self-perception. Terms like "empty," "bad," or "junk" applied to foods are associated in some research with more rigid, all-or-nothing eating attitudes. Nutrition educators increasingly favor value-neutral language that focuses on patterns rather than moral judgments about individual foods.
Third, the framing can inadvertently promote a guilt-based relationship with eating. When people internalize that certain foods are inherently "empty" or worthless, it can encourage all-or-nothing thinking that makes balanced eating harder, not easier. This is one reason many registered dietitians have moved away from the term in clinical practice.
For a more precise tool, the concept of nutrient density offers a better framework — it evaluates the ratio of beneficial nutrients to calories rather than sorting foods into good and bad bins.
What the Research Actually Supports
Nutrition research broadly supports reducing consumption of heavily processed foods high in added sugars and refined carbohydrates, particularly when they displace more nutrient-rich foods in the diet. The concern is less about individual items and more about patterns: diets consistently high in ultra-processed, low-nutrient foods are associated with poorer health outcomes over time.
~57%
Share of US calories from ultra-processed foods
Research published in BMJ Open estimated that ultra-processed foods accounted for roughly 57% of total caloric intake in US adults, highlighting the scale of low-nutrient food consumption.
17 tsp
Average daily added sugar intake for US adults
The American Heart Association has reported that Americans consume an average of about 17 teaspoons of added sugar per day, well above the recommended limits.
This is meaningfully different from saying any specific food is inherently harmful. The scientific and public health consensus focuses on habitual patterns — how much of what types of food people eat across months and years — rather than single-food verdicts.
It's also worth noting that the empty calorie concept applies unevenly across populations. For someone who is undernourished or has elevated caloric needs, a calorie-dense food with modest nutrient content may serve a genuine purpose. Blanket labels rarely account for individual context. If you're unsure how nutrition concepts apply to your own health situation, a registered dietitian is the most reliable guide.

A More Useful Way to Think About Food Quality
Rather than asking whether a food is "empty," a more productive question is: what does this food contribute relative to what I'm eating overall? That reframing shifts attention away from individual guilt and toward the bigger picture of dietary patterns.
Reading food labels can help — understanding nutrition facts labels gives you a concrete way to compare how much added sugar, fiber, vitamins, and minerals different options actually contain. And if you're considering removing whole categories of food from your diet, it's worth understanding the trade-offs involved before making significant changes.
The empty calorie concept has genuine value as a starting point for nutrition literacy. It signals that calories and quality are not synonymous. But treating it as the final word on what's worth eating — or what you should feel bad about eating — overshoots what the evidence actually says.
