  17. A positive urine drug test for illicit drugs
  18. History of major depression within <5 years from screening or which, in the opinion of a medical investigator, will impact the participant's ability to complete the study.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
PLACEBO_COMPARATOR: Placebo
Participants will receive powdered maltodextrin to provide equivalent calories and macronutrients without any fiber.
Powdered maltodextrin will be provided in pre-weighed portions for consumption in a 1 week titration with a 21 day intervention at full dose.
