First seen Nov 01, 2025 · Last updated May 16, 2026 · Updated 33 times

Summary

This study looks at how eating a lot of ultra-processed foods (like packaged snacks and sugary drinks) affects the way your body absorbs calories. Researchers will compare two diets: one where 80% of calories come from ultra-processed foods and another where only 20% do. They will measure the calories left in stool to see how much energy the body actually keeps. The study involves 20 adults with a BMI between 30 and 40 who are otherwise healthy.
