The best choices for a person, definitionally, are those they themselves deem best (whether they carry them out or not). No other person has a higher authority to decide "best" for them.
It's not any second party's place to say. Your actions plainly demonstrate that you find pleasurable choices (overeating, alcohol) better for you than healthy ones. That's fine and good.
Short term pleasure over long term health is a legitimate choice, if you (or anyone else) wishes to make it for your (or their) own body. Not everyone needs to uniformly prioritize quantity of life over quality of life.
