“Background Many investigators have sought to elucidate the hormonal response to feeding, as such an understanding may provide insight into important biological processes that occur in the postprandial state. Both the meal size [1, 2] and macronutrient type [3–5] may impact the hormonal response. Although this ensuing hormonal response may be important to a variety of individuals (e.g.
