“…16,17 In the present study, whey, casein and milk had similar effects on acute appetite sensation, but ad libitum EI at the subsequent lunch was significantly decreased by milk compared with the casein and the whey beverages. There was no significant difference in EI after the whey and the casein beverages.…”

“…Cumulative lipid oxidation was greater after the whey, casein and soy meals than after the high carbohydrate meal, and tended to be greater after the whey meal than after the soy meal (P ¼ 0.097). By contrast, Alfenas et al 17 observed a significantly higher DIT after a breakfast meal containing soy compared with a breakfast meal containing carbohydrate, but no significant difference in DIT after breakfast meals with soy, whey and casein. The respiratory quotient was significantly low after whey compared with soy, whereas casein was not significantly different from either whey or soy.…”

“…Others have reported no difference in the effect of whey and casein on satiety, 15 whilst some have reported that casein is more satiating than whey. 16,17 The aim of the present study was to compare the effect of whey, casein and milk, consumed as part of a mixed meal, on satiety, DIT and substrate oxidation.…”

The effect of milk proteins on appetite regulation and diet-induced thermogenesis

BACKGROUND/OBJECTIVES:There is increasing evidence to support that a high-protein diet may promote weight loss and prevent weight (re)gain better than a low-protein diet, and that the effect is due to higher diet-induced thermogenesis (DIT) and increased satiety. However, data on the effect of different types of protein are limited. In the present study we compare the effect of whey, casein and milk on DIT and satiety. SUBJECTS/METHODS: Seventeen slightly overweight (29±4 kg/m 2 ) male subjects completed the study. The study had a randomized, crossover design, where the effect on 4 h postprandial energy expenditure (EE), substrate oxidation and subjective appetite sensation of three isocaloric test meals containing either a whey drink, a casein drink or skim milk was examined. Energy intake (EI) at a subsequent ad libitum lunch was also measured. RESULTS: There was no significant effect on subjective appetite sensation, but EI at lunch was lower after the milk test meal than after the casein (9%; P ¼ 0.0260) and the whey (9%; P ¼ 0.0258) test meals. Postprandial lipid oxidation was significantly higher after the casein test meal compared with the whey test meal (P ¼ 0.0147) when adjusted for baseline values. There was no significant difference in effect on EE, protein oxidation or carbohydrate oxidation. CONCLUSIONS: Milk reduced subsequent EI more than isocaloric drinks containing only whey or casein. A small but significant increase in lipid oxidation was seen after casein compared with whey.

“…Glycemic index was also included within these diets but is not included in this discussion. In the adults who completed the study, the higher-protein diet led to less weight regain (MD: 20.93 kg; 95% CI: 20.31, 21.55 kg; P = 0.003) than the lower-protein diet did (66). The children who followed the higher-protein regimen had reductions in waist circumference (22.7 cm; 95% CI: 0.9, 5.1 cm; P , 0.007) and LDL cholesterol (20.25 mmol/L; 95% CI: 0.09, 0.41 mmol/L; P , 0.007) compared with those following the lower-protein version (78).…”

“…Although the impact of protein quality on appetite control and food intake is poorly characterized, there are data, albeit inconsistent, that show protein-source effects. In some (62,63), but not all (64)(65)(66), studies the consumption of whey protein elicited a greater reduction in postprandial hunger and a greater increase in postprandial satiety than consumption of casein and/or soy. The contribution of protein quality on these outcomes is further supported by the Veldhorst et al (50,51) studies that compared higher-with lower-protein meals but included different types of protein.…”

Over the past 20 y, higher-protein diets have been touted as a successful strategy to prevent or treat obesity through improvements in body weight management. These improvements are thought to be due, in part, to modulations in energy metabolism, appetite, and energy intake. Recent evidence also supports higher-protein diets for improvements in cardiometabolic risk factors. This article provides an overview of the literature that explores the mechanisms of action after acute protein consumption and the clinical health outcomes after consumption of long-term, higher-protein diets. Several meta-analyses of shorter-term, tightly controlled feeding studies showed greater weight loss, fat mass loss, and preservation of lean mass after higherprotein energy-restriction diets than after lower-protein energyrestriction diets. Reductions in triglycerides, blood pressure, and waist circumference were also reported. In addition, a review of the acute feeding trials confirms a modest satiety effect, including greater perceived fullness and elevated satiety hormones after higherprotein meals but does not support an effect on energy intake at the next eating occasion. Although shorter-term, tightly controlled feeding studies consistently identified benefits with increased protein consumption, longer-term studies produced limited and conflicting findings; nevertheless, a recent meta-analysis showed persistent benefits of a higher-protein weight-loss diet on body weight and fat mass. Dietary compliance appears to be the primary contributor to the discrepant findings because improvements in weight management were detected in those who adhered to the prescribed higher-protein regimen, whereas those who did not adhere to the diet had no marked improvements. Collectively, these data suggest that higher-protein diets that contain between 1.2 and 1.6 g protein $ kg 21 $ d 21 and potentially include meal-specific protein quantities of at least w25-30 g protein/meal provide improvements in appetite, body weight management, cardiometabolic risk factors, or all of these health outcomes; however, further strategies to increase dietary compliance with long-term dietary interventions are warranted.

Dietary proteins have been shown to stimulate thermogenesis, increase satiety, and improve insulin sensitivity in the short and long term. Animal‐based proteins (AP) and plant‐based proteins (PP) have different amino acid profiles, bioavailability, and digestibility, so it seems to have various short‐ and long‐term effects on metabolic responses. This review aimed to compare the findings of controlled clinical trials on postprandial effects of dietary Aps versus PPs on energy expenditure (EE), lipemia, glycemia, and insulinemia. Data are inconclusive regarding the postprandial effects of APs and PPs. However, there is some evidence indicating that APs increase postprandial EE, DIT, and SO more than PPs. With lipemia and glycemia, most studies showed that APs reduce or delay postprandial glycemia and lipemia and increase insulinemia more than PPs. The difference in amino acid composition, digestion and absorption rate, and gastric emptying rate between APs and PPs explains this difference.
