The Effects of Whey, Rice and Potato pRotein isOlates on appeTite rEgulatIoN in Healthy Men

Summary

INTRODUCTION: Global protein consumption has been increasing for decades due to changes in socio-economic demographics and consumer trends towards higher protein intake, which may be related to their health benefits in performance nutrition and appetite regulation. The additional intake of protein often occurs in the form of supplements. One of the main ingredients used in sports and weight loss supplements are animal-derived proteins such as whey, which are of high quality, containing all the essential amino acids required in human nutrition with a high absorption rate. However, whey protein has a high environmental footprint, and it may contribute to insulin resistance in susceptible groups (e.g. obese, T2DM, insulin resistant, or those with sarcopenic obesity).

Rice and potato protein isolates are high-quality plant proteins containing all essential amino acids comparably to whey protein. These plant-derived proteins may provide a more sustainable and accessible alternative to animal-derived proteins for appetite regulation and weight management.

Interventions

DIETARY_SUPPLEMENT

Whey protein isolate

Instantized BiPRO® 50g (equiv. 45.5g of total protein) presented to participants in a form of a shake. Other ingredients in the whey protein shake: * Tropicana Trop50 Orange Juice 207mL * Water 43 mL * Sucralose 0.5g The total energy 233.47Kcal. Participants instructed to consume the entire protein shake presented to them in 5 minutes on an empty stomach when attending the study.

DIETARY_SUPPLEMENT

Potato protein isolate

Solanic®100 48g (equiv. 45.3g of total protein) presented to participants in a form of a shake. Other ingredients in the potato protein shake: * Tropicana Trop50 Orange Juice 250mL * Sucralose 0.5g The total energy 233.46Kcal Participants instructed to consume the entire protein shake presented to them in 5 minutes on an empty stomach when attending the study.

DIETARY_SUPPLEMENT

Rice protein isolate

Oryzatein® Silk 90 50g (equiv. 45.5g of total protein) presented to participants in a form of a shake. Other ingredients in the rice protein shake: * Tropicana Trop50 Orange Juice 183mL * Water 67mL * Sucralose 0.5g The total energy 233.43Kcal Participants instructed to consume the entire protein shake presented to them in 5 minutes on an empty stomach when attending the study.
