NCT05934357

Brief Summary

The study aims to evaluate the metabolizable energy of the typical American diet with and without the inclusion of fiber. We hypothesize that including fiber in the diet will decrease the metabolizable energy of the diet resulting in more nutrient loss into the feces and urine.

Outcome Measures

Primary Outcomes (1)

  • Metabolizable Energy of the Diet

    The diets provided to participants will be analyzed for their energy and proximate analysis. Fecal and urine samples will be collected for 5 days during week 2 of each intervention period to calculate the total metabolizable energy of the diet. Energy and proximate analysis (dry matter, organic matter, crude protein, acid-hydrolyzed fat, and total dietary fiber) will be analyzed from the provided diet and the fecal samples. Energy will be analyzed from urine samples. The metabolizable energy content will be calculated according to the methods of Novotny et al. (2012), which considers the energy of the diet compared to the remaining energy in the collected fecal and urine samples.

    during the last 5 days of the 2 week intervention period

Secondary Outcomes (1)

  • Fecal Microbiota
