“Protein Appetite Leveraging” was presented at the 2015 Protein Trends & Technologies Seminar by Richard D. Mattes, MPH, PhD, RD, Distinguished Professor of Nutrition Science, Purdue University; Affiliated Scientist at the Monell Chemical Senses Center.
Abstract: It is well known that proteins provide essential amino acids required for life. What is less understood is the role they play in satiety and weight management. This presentation looked at theories and research that help delineate how proteins influence hunger, energy intake and energy expenditure. Additionally, the implications of a food’s sensory properties and expectation for satiety were touched on. This information provided an improved framework for the development of protein-enhanced products in the marketplace.
Excerpt of the written summary of this presentation: Mattes posed the question, “Are all calories equal? At the molecular level, the answer is yes.” “However,” he noted, “several food components are of interest for weight control at the organ and whole-body level, and research is showing that the energy from each may not be equal.”
Protein is one such food component that might alter other food choices. Some work indicates there might be a “protein-specific” effect, as rats deprived of protein will show a preference for protein consumption when provided access. Similar results have been noted in pregnant animals. Further, when fed a protein-restricted diet for 12 days, animals will try to “make up” the deficit when allowed protein for one hour per day.
