Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the effect of casein protein consumption both prior to sleep as well first thing in the morning on metabolism (increase satiety and appetite, lower resting metabolic rate, and lower blood sugar levels), when compared to nighttime protein or placebo consumption alone. Protein itself is a macronutrient that not only helps the body repair itself, and play a critical role in growth, it also aids in increasing satiety and decreasing appetite. Casein protein specifically is slow digesting dairy protein which may impact the body's metabolism for a longer period than other dairy proteins such as whey. The literature demonstrates nighttime protein ingestion prior to sleep increases metabolic rate and satiety the next morning. However, there appears to be no data on the metabolic effects of protein ingested both at night and in the morning.

Participants arrive to the lab, complete 30 mins resting metabolic rate assessment. Then they are provided with a shake to drink 30 mins before bed. They return to the lab the following morning for 30 min RMR, drink another shake and do 30 mins RMR before leaving the lab.
