What leads to fat build up and weight gain?

There are several different reasons as to why our bodies can change in physical shape, accumulating fat over time. Obesity is a serious issue, but not everyone experience it from the same causes. Sometimes, we inherit genetic traits that affect our susceptibility to gaining weight. Other times, our diet, addictions, reliance on some prescribed medications, pre-existing conditions such as Diabetes and thyroid issues can lead to fat buildup. Regardless of whether an individual has an extremely high daily sugar intake or has inherited bad genetics, the effects of fat buildup are the same.
