What is the meaning of quotes reading without reflecting like eating digesting?

This quote means that reading without reflecting is like eating without digesting. Just as you cannot benefit from food if you do not digest it, you cannot benefit from reading if you do not reflect on what you have read. Reflection is essential for understanding and retaining information, and for making connections between different pieces of information. When you reflect on what you have read, you are also more likely to remember it and to be able to apply it to your own life.
