Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
We propose to study both stool and urine energy loss in 24 individuals on two experimental diets (50% increased and 50% reduced nutrient load relative to body size) in a random cross-over design. Following this over/underfeeding, volunteers will also be randomly assigned to a placebo versus oral antibiotic medication arm. This study will extend our previous findings by investigating whether 1) nutrient absorption changes upon similar increases/decreases in relative nutrient load and 2) whether manipulation of gut microbial communities with antibiotics alters nutrient absorption and 3) how these changes may affect glucose tolerance and fat storage.
