Isn't this standard James at the minute? When he put on weight, it was there's a global pandemic, team thicc, no one sees you with your top off (unless you constantly get someone to take photos of you after bjj sessions). I'm guessing he's just weighed himself and realised he's lost a bit of weight, so naturally everyone else should and everyone should want to be him.
So lose weight, but not too much weight that you have more visible abs than him, as then you are boring. Do resistance training (though not sure if he goes to the gym any more) but don't get more muscular than him as then you must be on steroids.
Don't pursue money in your work as getting a nice house and car means your a knob, but having money to buy other expensive things, flying business class and randomly paying stuff for your mates (whether they want you to or not) is fine. Look at the knobhead flashing his cash on a car, but praise for me flashing my cash doing xyz.
Let man live, but tell everyone who does something different to you that they're a bleep.
