Study start date: May 1, 2008

Actual date on which the first participant was enrolled.

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.

Basic Science Study

Basic science studies help researchers understand how the body works or how a disease develops. They don't test treatments, but they build the foundation for future therapies.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
