By a News Reporter-Staff News Editor at Health & Medicine Week -- Research findings on Health and Medicine - Diet and Nutrition are discussed in a new report. According to news reporting originating in West Lafayette, Indiana, by NewsRx journalists, research stated, “Higher-protein (HP) energy-restriction diets improve weight management to a greater extent than normalprotein (NP) versions. Potential mechanisms of action with regard to assessment of eating behaviors across the day have not been widely examined during energy restriction.”
The news reporters obtained a quote from the research from Purdue University, “The objectives of this study were to test whether the consumption of an HP energy-restriction diet reduces carbohydrate and fat intakes through improvements in daily appetite, satiety, and food cravings compared with NP versions and to test whether protein type within the NP diets alters protein-related satiety. Seventeen overweight women [mean+/-SEM age: 36+/-1 y; body mass index (kg/m(2)): 28.4+/-0.1] completed a randomized, controlled-feeding crossover study. Participants were provided with the following; similar to 1250-kcal/d energy-restricted (-750-kcal/d deficit) diets, each for+/-d: HP [124 g protein/d; 60% from beef and 40% from plant sources (HP-BEEF)] or NP (48 g protein/d) that was protein-type matched (NP-BEEF) or unmatched [100% from plant-based sources (NP-PLANT)]. On day+/-of each diet period, participants completed a 12-h testing day containing repetitive appetite, satiety, and food-craving questionnaires. On day 7, the participants were asked to consume their protein requirement within each respective diet but were provided with a surplus of carbohydrate-and fat-rich foods to consume, ad libitum, at each eating occasion across the day. All outcomes reported were primary study outcomes. The HP-BEEF diet reduced daily hunger by 16%, desire to eat by 15%, prospective food consumption by 14%, and fast-food cravings by 15% but increased daily fullness by 25% compared with the NP-BEEF and NP-PLANT diets (all P< 0.05). However, consuming more protein throughout the day did not reduce the energy consumed ad libitum from the fat-and carbohydrate-rich foods (HP-BEEF: 2000+/-180 kcal/d; NP-BEEF: 2120+/-190 kcal/d; NP-PLANT: 2070+/-180 kcal/d). None of the outcomes differed between the NP-BEEF and NP-PLANT treatments.”
According to the news reporters, the research concluded: “Although appetite control, satiety, and food cravings improved after an HP energy-restriction diet, increased protein consumption did not reduce carbohydrate and fat intakes throughout the free-living test day in overweight healthy women exposed to highly palatable foods.”
