Women who reach a body-fat level under what percentage may experience menstrual changes?

1. 5-7 percent

2. 8-10 percent

3. 10-13 percent

4. 14-16 percent

The correct answer is: 10-13 percent

Women who reach a body-fat level under 10-13 percent may begin to experience menstrual changes due to the body's physiological responses to low fat reserves. Body fat plays a critical role in hormone production, particularly estrogen, which is essential for reproductive health. When body fat levels drop significantly, the body may interpret this as a signal of inadequate energy reserves, leading to a decrease in hormone production. This hormonal imbalance often results in irregular or halted menstrual cycles, a condition known as amenorrhea. Maintaining a body fat percentage within a healthy range supports optimal hormonal function and reproductive health. Therefore, the threshold of under 10-13 percent is significant because it marks a level at which women may start experiencing these physiological changes. Understanding this concept is vital for those involved in fitness and health, as it highlights the importance of balancing body composition with overall health, particularly for women.
