Because there's a tendency to spiel same thing on this forum. Sort of recognition if you will.
Do people realize that not everyone have the same goal or even desire to live the lifestyle? as you say (not you, subsequent poster said it but its a common response).
I'm 45 and sure diet is the key and I want to live healthly. But I'm being honest when I say, the main reason why I workout 6 days and cycle 200+ mile per week is because I love to eat. Do I want to be a bodybuilder - not even close. In fact I want to be like bruce lee (thin) but I know I could never have a body like that - I like to eat. So I workout and build muscle because thats whats easy for me, relatively. Do I care if I have a little love handle? Sure I do. Will I die from that love handle? No, like everything else, its a trade off. Do I want to live the "lifestyle" of eating bland chicken and over load my liver or balance it out with less protein and more than what people here will recommend amount of carb. Its a trade off.
So going back to OP's original question - sure I could of just said, hey get a strict diet and you'll lose it. I even have a previous post saying so. But in the end, I could see a different point of view and say, maybe, this guys is like me. And maybe he might be interested in what I went through - even though its not the "lifestyle" or even something I would even repeat. Its a different point of view - right or wrong without being in extreme.
The Phamacology comment wasn't directed toward you but lets be honest, we're here for a reason. Right workout, diet or not, we're all looking for something that will help with whatever we're looking for.
