What is a possible effect of excess protein in the body?

Excess protein in the body can lead to a strain on the kidneys. When protein is metabolized, it produces waste products, such as urea, that the kidneys must filter out of the bloodstream. A high intake of protein can make the kidneys work harder to excrete these waste products, which may be particularly concerning for individuals with pre-existing kidney conditions. Over time, this increased workload can potentially contribute to kidney damage or worsen existing kidney issues.

The other choices do not accurately reflect the potential effects of excess protein. While weight loss can occur under certain dietary conditions, excess protein does not inherently lead to weight loss; instead, it may contribute to weight gain if overall caloric intake exceeds energy expenditure. Increased energy levels are typically associated with a balanced diet rather than an excess of protein alone. Finally, improved digestion is more commonly linked to adequate fiber intake rather than excess protein, which can sometimes lead to digestive discomfort for some individuals.
