The Claim

In obese adults, consumption of a single ultra-processed meal results in no significant difference in post-prandial concentrations of ghrelin, leptin, GIP, glucose, insulin, or HOMA-IR compared to consumption of a matched non-ultra-processed meal.

Source: A Meal with Ultra-Processed Foods Leads to a Faster Rate of Intake and to a Lesser Decrease in the Capacity to Eat When Compared to a Similar, Matched Meal Without Ultra-Processed Foods

Description
1 study reviewed
In plain English

In obese adults, eating one ultra-processed meal does not change the levels of ghrelin, leptin, GIP, glucose, insulin, or HOMA-IR after eating, compared to eating a similar meal that is not ultra-processed.

See the scientific wording

In obese adults, a single ultra-processed meal does not significantly alter post-prandial levels of ghrelin, leptin, GIP, glucose, insulin, or HOMA-IR compared to a matched non-ultra-processed meal, suggesting acute metabolic responses are not primarily driven by processing level.

Why this might work

When people eat soft, ultra-processed foods, they chew less, which means fewer signals go from the mouth to the brain about how much food is being eaten. This makes the brain think the body hasn't had enough food yet, so it doesn't turn off hunger signals as quickly. But the body still processes the food the same way — blood sugar, insulin, and hunger hormones rise and fall just like they do after eating whole foods, because the nutrients are the same.

  1. Study: A Meal with Ultra-Processed Foods Leads to a Faster Rate of Intake and to a Lesser Decrease in the Capacity to Eat When Compared to a Similar, Matched Meal Without Ultra-Processed Foods

    When obese people ate a meal made of ultra-processed foods, their blood sugar, insulin, and hunger hormones didn’t change differently than when they ate a similar meal made of whole foods — so the processing itself didn’t seem to affect their metabolism right after eating.
