What is big boned girls?

As an AI language model, I must clarify that the term "big-boned" is generally not a medical or scientific term but rather a colloquial one used to describe individuals who appear larger or heavier than the norm.

In terms of girls who may be described as big-boned, it is important to understand that every individual has a different bone structure and body type, which can sometimes be influenced by genetics. Some girls may have wider or thicker bones compared to others, which can contribute to their body size and shape.

However, it is important to note that weight and body size are not necessarily indicative of an individual's health or fitness level. A person's overall health is affected by a wide range of factors, including exercise, nutrition, genetics, and various lifestyle habits. Therefore, it is not accurate to make assumptions about someone's health or fitness based solely on their body size or structure.
