There are two main reasons why breakfast requires protein supplementation: providing essential nutrients and maintaining stable blood sugar levels.

1. Providing Essential Nutrients: Protein is the foundation of life, serving as an essential substance that constitutes human cells and tissues, as well as a necessary component for life activities in the body. During sleep, the body experiences prolonged hunger, requiring adequate protein supplementation at breakfast to supply the nutrients needed by the body and help maintain normal physiological functions.

2. Maintaining stable blood sugar: The digestion and absorption of protein are relatively slow, helping the body maintain stable blood sugar levels and preventing rapid spikes or drops. This is particularly important for diabetic patients, as it helps avoid significant fluctuations in blood sugar and ensures stable glycemic control.

In summary, supplementing protein at breakfast is essential for providing necessary nutrients and maintaining stable blood sugar, thereby promoting overall health. It is recommended to choose high-quality protein sources such as eggs, milk, and soy products, and to maintain a healthy and balanced diet.
