Effects of Ultra Processed Food on Intestinal Energy Harvest

Source: ClinicalTrials.gov · Last updated 9 Oct 2026

Brief summary (registry, in English)

Ultra processed food is everywhere in modern society and may contain multiple ingredients that affect the way participants' bodies store energy. Some studies have shown that eating a diet high in ultra processed foods leads to weight gain, but these foods have not been studied enough to understand why. Recently, the gut microbiome has become a potential way to measure energy balance in the human body; this is done by measuring how many calories are in the stool. The investigators propose to test a very high ultra-processed food diet where 80% of calories are coming from ultra processed food and a low ultra processed food diet where 20% of the calories are coming from ultra processed food. This study will compare stool sample energy content of the two diets.
