The Claim

Over a 14-day period, ultra-processed diets with slow eating rate textures produce no significant differences in fasting metabolic markers, gut hormone responses, or inflammatory biomarkers compared to ultra-processed diets with fast eating rate textures in healthy adults.

Description
1 study reviewed
In plain English

In healthy adults, eating ultra-processed foods slowly versus quickly for 14 days does not change levels of fasting blood markers, gut hormones, or inflammation markers.

See the scientific wording

Ultra-processed diets with slow eating rate textures do not produce significant differences in fasting metabolic markers, gut hormone responses, or inflammatory biomarkers compared to fast eating rate textures over a 14-day period, suggesting that eating speed alone may not directly alter acute metabolic physiology in healthy adults.

Why this might work

When food is chewed slowly, the mouth sends stronger and longer signals to the brain about how much is being eaten, which makes a person feel full sooner and eat less. But even though this reduces how much food is eaten, the body still processes the food the same way — blood sugar, insulin, gut hormones, and inflammation levels stay unchanged because the type of food and its nutrients are identical, regardless of how fast it is eaten.

    Even when people ate the same junk food more slowly, their blood sugar, insulin, and inflammation levels didn’t change—so how fast you eat doesn’t seem to affect your body’s metabolism in the short term.
