Essential body fat should be at least what percentage in females?

Essential body fat for females is recognized as being necessary for the maintenance of health and normal physiological functions. This fat is crucial for processes such as hormone production, which influences reproductive system functions, and is necessary for overall energy balance. In females, essential body fat is typically higher than in males due to reproductive requirements.

The range of 8-12% specifically aligns with recognized standards for essential body fat in women. This percentage ensures that women have adequate fat reserves to support reproductive health while balancing overall body composition. It's important to note that percentages below this range may lead to disruptions in hormonal balance and associated health issues. Therefore, the answer correctly reflects the necessary guidelines for maintaining essential body fat in females, ensuring both health and reproductive capability are supported.
