Effect of High-calcium Intake on Appetite, Insulinemia and Incretins
Effect of High-calcium Intake on Appetite, Insulinemia and Incretins

The purpose of this study is to investigate the appetite, insulin and incretin hormone responses to a high-calcium meal.

Participants will be provided with control and high-calcium meals. Insulin, appetite, glucagon-like peptide-1 and glucose-dependent insulinotropic peptide responses will be assessed, along with rates of substrate oxidation.
