The Claim

Consumption of ultra-processed foods increases daily energy intake by approximately 814 kcal in young overweight men, primarily through elevated intake of carbohydrates and fats, even under controlled feeding conditions with matched total energy and macronutrient targets.

Cause and effect
1 study reviewed
In plain English

Young overweight men who eat ultra-processed foods consume about 814 more calories per day than when eating unprocessed foods with the same total energy and macronutrient content, due to higher intake of carbohydrates and fats.

See the scientific wording

Ultra-processed food consumption increases daily energy intake by approximately 814 kcal in young overweight men, primarily through elevated intake of carbohydrates and fats, despite matched total energy and macronutrient targets in controlled feeding conditions.

Why this might work

Ultra-processed foods are softer and contain less fiber, so people chew them less and eat them faster. This means the stomach and intestines don't get enough time to signal fullness to the brain. As a result, the body doesn't stop eating until it has taken in far more calories than needed, even when the food has the same nutrients as healthier options.

  1. Study: Ultra‐processed foods cause weight gain and increased energy intake associated with reduced chewing frequency: A randomized, open‐label, crossover study

    Even when given meals with the same calories and nutrients, people ate over 800 more calories a day when eating ultra-processed foods—likely because they chewed less and ate faster—leading to weight gain.
