Evaluate the options provided: diabetes, cardiovascular disease, breast cancer, and colon cancer. While obesity can increase the risk of these conditions, it is directly caused by overnourishment.
Conclude that the direct consequence of overnourishment is obesity, which can subsequently lead to other health issues such as diabetes and cardiovascular disease.
