Granted, nobody's going to make a reality TV series based on my diet experiences. I did have a comical moment when I went to the gym the first week, climbed aboard one of those StairMaster-like contraptions and almost fell off. Maybe there would be some melodramatic footage if someone filmed me every time I went through a McDonald's drive-thru to buy my kids the occasional Happy Meal or ice cream. I'm sure that I look like a tragic romantic figure every time I pass by the posters and pictures of McDonald's Angus burger.
This is a nice way to add some realism in a funny way. He is proud of the weight he has lost, while realizing that it isn't quite dramatic enough to start a reality show about. This experience at the gym is something a lot of people have probably dealt with. This tangent about his un-dramatic weight loss leads into an interesting scenario between him and McDonalds.
I bought cupcakes for my daughter's kindergarten class to celebrate her birthday, and I didn't swipe any for myself (we had extra and don't think I wasn't tempted).
This is almost like giving himself a pat on the back. The parenthesis are an aside to the reader, letting them know that although he didn't actually eat the cupcake, he was still tempted and is still human and wrestling with his diet.
OK, maybe that's not exactly how our visits to the drive-thru have worked out. As I was saying, mostly this is a drama-free diet.
This snaps him back into reality. He is conversational with the readers and he is honest with them. Although he was initially skeptical about how this diet would work out, he is now realizing that although he isn't dropping tons and tons of weight, he isn't experiencing much drama. This offers hope to readers, and he is giving it to them in a way that isn't overly motivational. Some people become annoyed always hearing that they can do it, and that it'll be easy. This is motivation that seems to be coming from a friend. He is letting you know that he is trying it, and so far it isn't so bad.
This is a funny, and more negative way of saying that he has stuck to his diet. He is clearly still doubting himself and waiting for the day that he caves, but he is also pleasantly surprised that he has still been able to diet. Rather than just saying he ate healthy this week, or he resisted temptation, he refers to fast food and junk food as chances to destroy his new lifestyle.
-Angus, I only met you several months before I began this diet. Angus, I hardly knew ye.
-"Dad, would you stop kissing the menu?"
-Angus, call me--
-"Dad!"
Geoff has personified the angus burger and has not only started dialogue with it but has started a relationship with the burger. This shows that food is more than just food to Geoff, and now that it has been taken away from him it is equivalent to losing a lover.
I also lost money by not going to the YMCA -- we have a membership, and I should be using it more -- but I didn't make it once this week. If I had, I might have finally dropped enough to get into the high 240s.
The dashes are a way for Geoff to take a moment to explain why not using the YMCA gym lost money for him. This is him reflecting on what he could have done better, and realizing that it would have helped him lose weight and make the most of the money he is spending.
I used to spend almost $100 a month on snacks and generally unnecessary food -- and frankly, I'd rather not believe that.
The dash again is similar to the use of parenthesis. It is a bit of an aside to the reader. It isn't necessary to understand what he is saying, but it lets you know his feelings about what he is realizing, and the mental pause that people take when they see a dash adds to the voice created when he adds his opinion about what he has just realized.
