What Is Volume Eating? A Dietitian’s Top Tip for Feeling Satisfied on Fewer Calories

Most weight-loss advice centers on smaller portions and cutting back. But there is another approach that can let you fill your plate without dramatically increasing calories: volume eating.

“The idea is to focus on foods that provide a lot of volume for relatively few calories, such as vegetables, fruit and broth-based soups,” registered dietitian Erin Palinski-Wade tells TODAY.com. “These foods tend to be naturally rich in water and fiber, which can help you feel satisfied with fewer calories overall.”

That may sound ideal — eating enough to feel full while still maintaining a calorie deficit — but Palinski-Wade says there are important points to consider.

What Is Volume Eating for Weight Loss?

“I like to think of it as a strategy for building more satisfying meals rather than another restrictive diet,” says Palinski-Wade.

It can be especially helpful for people trying to lose or maintain weight who still struggle to feel full, she adds. Instead of drastically shrinking portions or eliminating higher-calorie foods you enjoy, you can swap in foods that allow for larger, more filling servings at fewer calories. That can leave you satisfied after meals and, in some cases, with room for an occasional higher-calorie treat.

Research supports the approach. One analysis of 31 studies found that lowering the calorie density of meals helped reduce overall calorie intake. “Other research has found that people eating lower energy-density diets could actually consume 1-2 pounds more food per day while taking in fewer calories and losing more weight over six months,” adds Palinski-Wade.

Who Should Consider Volume Eating?

People trying to manage their weight, whether by losing or maintaining it, may find volume eating useful. It can feel discouraging to see less food on your plate if you are used to larger servings and the comfort of feeling full at the end of a meal.

“Choosing more high-volume foods may make it easier to manage calories without feeling deprived,” says Palinksi-Wade.

Even if weight control is not your goal, there can still be benefits. Palinksi-Wade says people who eat out of habit, boredom or emotional reasons may appreciate the familiar and soothing act of chewing and eating.

“And for the many Americans who aren’t eating enough fruits and vegetables,” she adds, “focusing on adding more volume through produce can be a great way to improve overall nutrition.”

Who Should Avoid Volume Eating?

While this method can help some people, Palinski-Wade says several groups should be cautious.

For those with a current or past eating disorder, including binge eating disorder, “this approach may reinforce an unhealthy relationship with food or feelings of fullness,” she says.

If your attention shifts from feeling satisfied after eating to simply consuming the largest amount of food for the fewest calories while ignoring hunger and fullness cues, volume eating is probably not the right fit.

“People with certain digestive conditions, such as IBS, Crohn’s disease or other forms of inflammatory bowel disease, may also struggle with large amounts of high-fiber foods,” says Palinski-Wade. “Anyone with a history of bowel obstruction, bowel surgery, or difficulty absorbing nutrients should speak with their healthcare provider before significantly increasing fiber intake.”

People taking GLP-1 medications should also be careful. Large portions, even when low in calories, can worsen nausea and stomach discomfort because these drugs slow digestion. “For these individuals, prioritizing protein and nutrient-dense foods in smaller portions is generally a better strategy,” says Palinski-Wade.

Finally, volume eating is not ideal for people who burn energy quickly. Athletes and highly active gym-goers, runners or swimmers may struggle to get enough calories from large amounts of low-calorie foods to support training, performance and recovery.

How to Practice Volume Eating

Prioritize Foods High in Water and Fiber

Leafy greens, cucumbers, peppers, berries and watermelon are all good examples, says Palinkski-Wade. They take up plenty of space on your plate and in your stomach without adding much to your daily calorie total.

When in Doubt, Try Soup

One simple strategy is to begin meals with a broth-based soup to make them more filling for fewer calories, she says. “One study found that people who ate two servings of low-calorie-density soup each day lost 50% more weight over a year than those consuming the same calories from snack foods,” says Palinski-Wade. “And including a wider variety of low-energy-density foods may also help improve overall diet quality.”

Keep in Mind When Volume Eating…

Volume eating can shape hunger and fullness in both helpful and unhelpful ways. On the positive side, lower-calorie foods can create the familiar feeling of comfortable fullness as they occupy more space in the stomach. “That physical stretching sends signals to your brain that you’re getting full, which may help you feel satisfied while consuming fewer calories,” Palinski-Wade says.

Still, volume should not be the only thing you think about. Focusing only on how much food you can eat may cause you to overlook balanced meals. Each meal should include enough protein, carbs, healthy fats, fiber, vitamins and minerals. Getting the right mix of macro and micronutrients matters for satiety too. “The goal should be to feel comfortably satisfied after eating, not to feel as physically full as possible,” says Palinksi-Wade.

While eating, pause to check in with yourself. About halfway through your meal, ask whether you are still hungry or simply eating because food is in front of you.

“It can take about 20 minutes for your brain to fully register feelings of fullness,” she says. “Slowing down and checking in with yourself during a meal can make a big difference.”

If you are still hungry about 20 minutes after finishing, it is fine to eat more.
