The Claim
Consumption of ultra-processed foods reduces chewing frequency by approximately 20% per calorie compared to consumption of non-ultra-processed foods in young overweight men, leading to faster eating rates and increased energy intake through diminished satiety signals.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Young overweight men who eat ultra-processed foods chew less frequently per calorie than when they eat non-ultra-processed foods, resulting in faster eating and higher total calorie intake due to reduced satiety signals.
See the scientific wording
Consumption of ultra-processed foods reduces chewing frequency by approximately 20% per calorie compared to non-ultra-processed foods in young overweight men, which may contribute to faster eating rates and increased energy intake by diminishing satiety signals.
Ultra-processed foods are softer and contain less fiber, so people chew less and eat faster. This reduces signals from the mouth and gut that tell the brain it's full. Less chewing also means fewer signals reach the brain's appetite control center, and less fiber means the gut produces fewer chemicals that signal fullness. As a result, the brain doesn't register fullness in time, so eating continues longer and more calories are consumed.
What the research says
1 studyWhen people ate ultra-processed foods like chips and cookies, they chewed less per bite and ended up eating more calories and gaining weight—even though they weren’t told to eat more. This suggests these foods make you eat faster and feel less full.
