It is like going to the gym everyday but not managing your diet.  

Make believe you just happen to have something you think he will like e.g. some really nice chocolates or a good wine and tell him you need someone to give it to because you are on a diet.

I have never heard of anybody's car being keyed for their political views (maybe by a select few if you find yourself with a trump sticker on your vehicle in a place like Spokane).

Sorry, only you know whether your preference is chicken or fish, and which one is more suitable to your diet...

Do they need a diet or am I out of line?

I'd bet that some of them have a diet that consists of cereal, fast food, and heroin.Could you tell them that the stove is not for heating and if you catch it being used as a furnace, you will remove it?

I'm not suggesting you put the family on the PB&J diet or anything extreme.

I highly recommend trying the apps for you phone to relieve stress.One of my friend's wife is hooked on Celexa, Ambien, Xanax, diet coke, and vodka.

It's not just RE, there are signs for diets, yoga classes, Tupperware type parties, all kinds of junk.My opinion is that if someone is willing to break laws intentionally then where do they draw they line in the business dealings, will they do anything else illegal or off color or unethical?

In 2007, through diet and exercise, I lost over 250 pounds, and have kept it off.
