Protein leverage hypothesis
Protein leverage hypothesis
The Protein leverage hypothesis (pronunciation: proh-teen lev-er-ij hy-po-thesis) is a theory in the field of Nutritional Science that suggests that the body's inherent drive to reach a certain protein target can influence overall energy intake, potentially leading to overeating and obesity when the diet is low in protein.
Etymology
The term "Protein leverage hypothesis" is derived from the words "protein", a type of nutrient found in food, "leverage", meaning influence or power, and "hypothesis", a proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Concept
The Protein leverage hypothesis was first proposed by Simpson and Raubenheimer in 2005. According to this hypothesis, if the proportion of protein in the diet falls, individuals will over-consume energy in an attempt to maintain their optimal protein intake. This over-consumption of energy can lead to weight gain and obesity.
