Satiety of High-protein Ramen Noodles

The aim of this study is to determine if high-protein instant ramen noodles acutely increase satiety, reduce hunger, and improve blood sugar levels compared to standard instant ramen noodles in generally healthy young to middle aged adults. In addition, we aim to test if intake of high-protein instant ramen noodles reduces caloric intake at the next meal compared to standard instant ramen noodles.
