Your not wrong, but I just want to make an aside about how I think 'obvious' is a dirty word. Things are only ever obvious when you already have domain knowledge, which you can't assume of everyone even in something as ubiquitous as diet. Yes, once you understand hobbies or dieting the vast majority of down to earth honest advice is going to be HIGHLY boring and repetitive. But Some people still might not have got the message, and some messages are worth repeating to help them out. All this withstanding, I also don't feel like this stuff is HN material.
