Abstract Objective The aim of this study was to assess the satiating efficacy of milk proteins compared to carbohydrates in twenty women during post-exercise period. Methods A milk protein-enriched beverage (MPB), and an isocaloric carbohydrate-enriched beverage (CB) containing respectively 9.3 g and 0.3 g of milk proteins per 100 mL beverage, were developed and tested in a satiety study with 20 free-living healthy and normal weight women. The participants drank 250 mL of the two beverages after an aerobic exercise session, filled daily food diaries and rated their appetite on visual analogue scale (VAS), in two days over three consecutive weeks. A psychometric evaluation of eating behaviour was obtained by three-factor eating questionnaire (TFEQ). Results No differences in appetite feelings and energy intakes between MPB and CB were found in the study population. However, 9 participants were significantly less hungry (− 9% vs + 15%, p 0.03) and ate later (208 min vs 127 min, p 0.03) and less (− 10% vs + 8% daily energy intake, p 0.01) when they had MPB than CB. These women had a slightly higher BMI and were more restrained than the others. Conclusions Data showed that MPB compared to CB could modify daily eating habits by enhancing satiety in women with a stronger cognitive control of eating behaviour. Highlights • A milk protein and an isocaloric carbohydrate enriched beverage were developed. • The two beverages did not elicit different appetite in 20 women after exercise. • The milk protein beverage reduced hunger and energy intake in more restrained women. • Cognitive control may counterbalance lacking protein-induced homeostatic mechanisms.
