The Claim
A diet composed of ultra-processed foods with slow eating rate textures does not significantly change body weight, fat mass, or fat-free mass over a 14-day period, even when energy intake is reduced.
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.
Eating ultra-processed foods slowly for 14 days does not change body weight, fat mass, or muscle mass, even if people consume fewer calories.
See the scientific wording
Ultra-processed diets with slow eating rate textures do not significantly alter body weight, fat mass, or fat-free mass over a 14-day period despite reduced energy intake, indicating that short-term caloric reduction from eating rate changes may not translate to measurable body composition changes.
When people eat harder, chewier ultra-processed foods slowly, their mouth and throat send stronger fullness signals to the brain, and their gut releases more hormones that stop hunger. This makes them eat fewer calories. But in just two weeks, the body does not lose weight or fat because the calorie reduction is too small and the body holds onto its energy stores.
What the research says
1 studyWhen people ate ultra-processed foods more slowly, they consumed fewer calories—but their weight and body fat didn’t change in two weeks. This suggests that just eating slower for a short time isn’t enough to lose weight or change body composition.
