One of those is not like the other. All you really have to do to lose weight is to eat less (where less is defined as "fewer calories"). There's nothing more to it. That's the entire method. Everything else is just there to aid you in accomplishing that goal. This is a perfect example illustrating why simple and easy aren't synonyms. Losing weight is simple (it's literally a single thing you have to do), but far from easy since chocolate is really tasty.
