Obesity, desires, and excess

Is obesity the result of thwarted desires?

Survival in evolution past times seems to favour those who had a strong desire for survival, desires for action, desires for work, and those things work can bring. In modern times, survival is no longer dependent on such thing, but social skills, and, combined with birth control, does not cause increase in the birthrate, but a decline in birth rate. Aka, less evolution. But the desires remain.

Many of our desires are beyond our needs. Is overeating one of those desires, or needs that is simply an available way of satisfying an evolutionary desires in a biologically damaging way?
