Daily Protein Intake Patterns on Energy Metabolism and the Motivation to Snack

2016-06-12 16:31:25 | BioPortfolio

Summary

The purpose of this study is to determine if when one eats protein can change how the body uses food for energy. Researchers will also test if eating a high protein breakfast can change one's craving for snack foods.

Description

The purpose of this study is to determine if consuming 30 g of high-quality protein at each meal can increase fat utilization and shift between-meal snack choices. While the benefits of high-protein diets are well known, little is known about the optimal amount of protein that should be eaten at each meal. Most Americans eat little protein at breakfast and lunch and most of their protein at the evening meal. Current guidelines for protein are based on body weight; however, recent evidence indicates that absolute amounts of protein at each meal are needed to maintain metabolically active fat-free mass. This suggests that a more even protein consumption pattern across daily meals may positively influence energy metabolism. In addition, recent evidence indicates that protein may reduce activity in the food reward areas of the brain. This suggests that protein may influence between-meal snacking by decreasing the relative reinforcing value (RRV) of highly rewarding snack foods. The RRV of a food is an empirical measure of its motivating value and energy-dense foods are highly reinforcing, especially for obese individuals. This study will be the first to investigate the role of the daily distribution of protein intake on energy metabolism and modifying snacking behavior.

Medical and Biotech [MESH] Definitions

A mitochondrial uncoupling protein that is expressed in heart and skeletal muscle tissues. It functions to regulate tissue respiration, energy balance, and THERMOGENESIS. Mutations in the UCP3 gene are associated with OBESITY.

A secreted protein of approximately 131 amino acids that is related to AGOUTI SIGNALING PROTEIN and is also an antagonist of MELANOCORTIN RECEPTOR activity. It is expressed primarily in the HYPOTHALAMUS and the ADRENAL GLAND. As a paracrine signaling molecule, AGRP is known to regulate food intake and body weight. Elevated AGRP has been associated with OBESITY.

A secreted protein of approximately 131 amino acids (depending on species) that regulates the synthesis of eumelanin (brown/black) pigments in MELANOCYTES. Agouti protein antagonizes the signaling of MELANOCORTIN RECEPTORS and has wide distribution including ADIPOSE TISSUE; GONADS; and HEART. Its overexpression in agouti mice results in uniform yellow coat color, OBESITY, and metabolic defects similar to type II diabetes in humans.
