Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Intervention study with three treatment groups in a randomised, single-blind, triple crossover design.

Study population: Healthy male participants will receive three different isocaloric and -volumetric protein shakes prepared using whey, rice and potato protein powders on different trial days with at least a one-week washout period apart.

Biological samples (blood and saliva samples) are collected at various time points during the visit. Blood samples are collected at baseline 10 min prior (T-10), then at 30 min (T30), 60 min (T60), 120 min (T120) and at 180 min (T180) after protein shake consumption. Saliva samples are collected at baseline (T-10), then at every 30 minutes following protein shake consumption (T30, T60, T90, T120, T150, T180). In addition, pertinent questionnaires Visual Analogue Scale \[VAS\] for the assessment of satiety and VAS for the assessment of protein shakes' perception will be collected at T-10, T30, T60, T90, T120, T150, T180 and at T0, respectively
