Summary

The goal if this study is to determine how oral lactate ingestion affects markers of appetite regulation. Researchers will compare oral lactate ingestion to a sodium chloride placebo. Participants will consume the lactate or placebo solution and then have blood samples and assessments of appetite over the course of 90 min. Free-living energy intake will be measured for 3 days surrounding each experimental session.

Detailed description

The purpose of this study is to explore the effects of oral lactate ingestion on appetite regulation in humans. To do this males and females will report to the laboratory for 2 experimental sessions completed in a counterbalanced, double-blinded manner. During one session a lactate solution will be ingested, in another session an equimolar sodium chloride solution will be ingested that matches the osmolarity of the lactate condition. Venous blood samples and subjective appetite perceptions will be obtained at five time points during each experimental session. Energy expenditure will be measured through accelerometers placed on the participants anterior thigh by an investigator on the morning the day before the session and worn over the experimental period (day before, day of, day after) recording their physical activity. Energy intake will be tracked using a smartphone mobile application called Keenoa over the same time period the accelerometers are worn.
