Losing Weight?

OK, so I'm loitering down Main St. and I see this cool cat approaching me. He looks like Steve McGillivray...but it isn't Steve McGillivray. Anyway, I just ignore the dude but as he approaches me he says "Hey Itsum! How ya doing?". I just look at him and I'm dumbfounded. It is Steve and I can't believe what I'm seeing. The guy's lost like a ton of weight. He used to be this fat ass dude weighing 250 lbs and now he's not an ounce more than 180 lbs!! I'm at a loss for words and all I can say to him is "WTF!!".
He starts babbling off to me about how much weight he's lost (like I can't see!) and how he went from a 44 waist to a 36 and he threw out all his clothes and he's got a whole new wardrobe and all that type of stuff. The guys just brimming with confidence and he's telling me about all these hot chics he meets at the gym and how many Mercedes Benz's he's sold (he's, apparently, now the the #2 salesman for Mercedes).
I just feel great as I'm listening to all his stories and I can't stop smiling and I just think to myself..."man, here's a guy who turned his life around!" So we say goodbye and decide we'll go for a drink sometime and I carry on walking down Main St. (now I'm walking...I'm not loitering anymore...I've got this spring in my step) and I think that maybe I should also lose a pound or two and maybe I should start hitting the gym every now and again.
I didn't hear from him after that day but I hear all these rumors about how cool he is and how he went on this diet and lost weight and how he's pulling all these hot chics and shit.... and I'm digging this.
About a year later, I'm walking up Main St. and, lo and behold, I see Steve approaching me and he says "How ya doing, Itsum?" and I just look at him and I say "WTF!!!". I knew right then that it was a mistake and I shouldn't have said "WTF!!!". I was shocked. The dude was enormous ..... he was like, at least, 300lbs and looked miserable and upset and I just couldn't get any words out of my mouth and before I could say anything he said - " Hey, good to see ya...I'll see ya around".
I just felt terrible for Steve.........so I just went into the Fox & Firkin and knocked back a cold one and I thought about how bad some of these diets are. You lose all that weight and then you put even more weight on and it just screws up your life. It's like a yo-yo...up and down or like someone who suffers from bi-polar depression...when he's up everything is cool and when he's down life is a bitch!
By the way, if anything like this happens to a female friend of yours, please take my advice and don't ever say "WTF" after she's been on a diet and then she puts on weight again. A lady is more sensitive to these weight issues than a man is and if you say "WTF" when you see her, she is likely to go home and commit sewerage (that's the term I use for committing suicide because when you commit suicide it's like the shit hitting the fan).
Women take these weight things very seriously...it's like a matter of life and death with them. So please be considerate!
Anyway, I'm not a nutritionist so I don't understand all these diets and how they work...but I sure think that they can be dangerous!!
