The Study
Passive overconsumption? Limited evidence of compensation in meal size when consuming foods high in energy density: Two randomised crossover experiments.
This study gave people different foods and saw how much they ate when they could eat as much as they wanted. It found that when the food had more calories per bite, people ate more calories—but it didn't prove that eating these foods every day makes people gain weight.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
When food is packed with more calories per bite, people eat the same amount by weight but take in way more calories—and they don’t eat less later to make up for it.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes—this means people unknowingly consume hundreds of extra calories daily from foods like cookies, cheese, or fried snacks, which can lead to weight gain over time.
- 2Eating high-energy-density food (over 3.0 kcal/g) led to eating 240 more calories than medium or low-density meals, even though the weight of food eaten stayed the same.

When people eat meals that are more energy-dense—meaning more calories per gram—they consume about 240 more calories in one sitting than when eating meals with lower energy density, and they do not eat less food to compensate.
Eating meals with high calorie density does not cause people to eat less later in the day when their food intake is measured in controlled settings.
When meals contain more calories per gram, people consume more total calories even if they eat the same amount of food, showing that calorie density influences intake more than portion size in the short term.
When food is made more calorie-dense, people eat the same amount in grams but take in more calories, without changing how much food they serve themselves.
As the calorie density of meals increases from low to high, total calorie intake increases in a straight-line pattern without any sudden change at 1.7–2.0 kcal/g, and there is no evidence that people eat less after this point.
Mammalian dairy products have biological properties that increase energy intake in infants by providing concentrated calories and reducing signals that tell the body to stop eating.
