Consuming excess protein can indeed put stress on the liver and kidneys. When protein intake exceeds the body's needs, the body must metabolize the surplus. The liver plays a crucial role in breaking down amino acids, while the kidneys are responsible for filtering out the byproducts of protein metabolism, such as urea. If protein consumption is consistently high, these organs may become overworked, potentially leading to increased risk of conditions like kidney stones or impaired kidney function over time.

While protein is critical for muscle synthesis and repair, excessive intake does not promote additional muscle growth and can have detrimental effects on the body, particularly concerning organ health. This highlights the importance of balancing protein intake within recommended dietary guidelines to maintain optimal health.
