Primary purpose basic science
(Active Comparator)
Complete whey protein.
whey Whey.
Preload containing complete whey protein.
(Active Comparator)
Complete whey protein missing the CMP (aka GMP) portion of the peptide.
whey-cmp Whey-CMP
Preload containing complete whey protein which is missing the CMP/GMP portion of the protein.
(Placebo Comparator)
Placebo preload control, matched for energy.
control Control
Preload control matched for energy to the other 5 preloads.
(Active Comparator)
Small peptide cleaved from complete whey protein.
cmp CMP
Preload containing the CMP (casinomacropeptide) portion cleaved from complete whey protein.
(Active Comparator)
Complete milk protein.
mpi MPI
Preload containing whole milk protein.
(Active Comparator)
Preload containing casein.
cpi CPI
Preload containing sodium caseinate.

Additional Information

Official title Characterization of the Physiological and Subjective Satiety Response to Preloads Varying in Bioactive Dairy Proteins
Principal investigator Britt Burton-Freeman, PhD, MS
Description Assessing 5 different milk derived proteins versus placebo for appetite regulation and satiety, delivered via shake vehicle. Subjects will attend a 5 hour post-prandial study day. Subjects will keep food records 1 and 3 days prior to study visit, day of visit, and day after visit; food to be weighed using study provided dietary scale.
