And let's not forget, once again, that genes very seldom affect only one
thing. Most often they affect several things. People tend to think that
genes encode individual aspects of the human biology, and that you can
just "fine-tune" each individual aspect by tinkering with its correspondent
gene. But that's not how it usually works.

It's not impossible that the fact that our bodies tend to store all the
extra fat they can get rather than being "moderate" about it may be the
result of a gene that, if modified, would affect something else much more
negatively.

(Although it's also not impossible that "fixing" the obesity problem by
tinkering with the necessary gene could also have other beneficial
ancillary consequences. However, I would guess this to be unlikely
because if it were the case, it would have probably happened on its own
a long time ago.)
