Final answer:
In females, the body fat should never drop below 20 percent of their total weight, as it is important for reproduction and influenced by hormones.
Step-by-step explanation:
In females, the body fat should never drop below 20 percent of their total weight. This is because females naturally have higher fat mass as compared to males, which is needed for reproduction and influenced by hormones. Having a lower body fat percentage can have negative effects on a female's health.
In assessing body fat content, methods such as the skin-fold test can be used, which is noninvasive and fairly accurate for determining fat mass. It is paramount for both males and females to maintain optimal body fat levels, with recommended fat content for females being between 20 and 30 percent of total body weight.
